Site Preparation

This section describes the steps to take and the considerations you should keep in mind prior to installing an SES chassis in a rack. It also contains information that applies to an SES installation in a Cisco closed rack. If the switch arrives in a Cisco closed rack, your initial concerns would be the cabinet grounding, and power connections. For specifications on the enclosure and power system, see the Appendix A, "Technical Specifications."

This section includes:

Parts Checklist

Before proceeding with the installation, verify that all the ordered parts are present and in good condition. Store a record of the parts and serial numbers. If any parts are missing or damaged, contact your sales representative.

Card Slot Locations

Slots are 1 and 2 are always double-height slots and reserved for the primary and redundant SES Processor Switching Modules (SES-PXMs). Slots 3 through 7 (and 3-7 and 10-14 for single-height modules) are used for various service modules. (Remember no service module slots are used when the SES is used as a BPX SES PNNI controller). Each service module slot can accept 1 single-height card or be converted to accept two double-height cards.

If you are considering any future card changes in which you replace a single-height card with a double-height card, place the single-height replacement candidates in as low of a slot number as possible, that is start with slot 3. Remember when you are converting single height slots into double height slots, you must start from the bottom. For example, before you can convert slot 4 into a double height slot, you must first have converted slot 3.

Site Requirements

The site must satisfy the requirements in the following categories:

The SES is typically co-located in a rack with either an IGX switch or an BPX switch. Refer to the Cisco IGX 8400 Series Installation and Configuration or the Cisco BPX 8600 Series Installation and Configuration documents for information about rack and cabinet moutned switches.
For displacement information for the Cisco WAN components in the Cisco cabinet, refer to Appendix C, "Cisco Cabinet Configurations".
The operating environment should be as follows:
Temperature and humidity range: 0º to 40ºC (32º to 104ºF) for normal operation, 50ºC for up to 72 hours. Recommend range of 20º to 30ºC. Up to 85% relative humidity, non-condensing.
For AC power use, an AC power source must be available within 6 feet (1.8 m) of the SES. For systems using a DC source, Cisco does not supply the DC power cord, so the user or installer determines the wire length and the distance to the DC source. The wire should be 10 AWG (4 square millimeters).
A fully loaded, AC-powered SES dissipates up to 4,800 BTUs (1.4 KW hour). A DC-powered SES dissipates up to 4,100 BTUs.
A fully loaded, DC-powered SES can weigh up to 120 lbs (54.3 Kgs). A fully loaded AC-powered SES can weigh up to 150 lbs (68.03 Kgs).

Caution  If you move a Cisco-supplied cabinet, do not push it at its sides. Push at the front or back.

Raised flooring with sufficient under-floor space for external cabling is best,
The location of the IGX or BPX switch which has a co-located SES should accommodate the routing of the data cables and the termination of the telephone company's or common carrier's circuits.
The building should provide adequate grounding to prevent damage from electrostatic discharge. See the sections "Bonding and Grounding " in the IGX or BPX installation documents for specific details.
In addition, the SES comes with a wrist strap that you can connect to the rear of the chassis near the ground lug or to a convenient point on the front of the chassis. You should put on a wrist strap before handling any cards.

Seismic Considerations

In Cisco-supplied cabinets, a feature is available for seismic anchoring. Holes exist in the upper and lower corners for 3/8" or 1/2" bolts. Also, an optional stability plate can be purchased with the Cisco cabinet. The stability plate is bolted to the floor, then the Cisco cabinet is bolted to the stability plate. The "Seismic" section in the IGX or BPX installation documents contains instructions for installing the seismic stability plate.

Power and Grounding

This section lists the requirements that relate to electrical power and grounding. These requirements cover installations at Central Office (CO) and Private Enterprise locations.

AC Power Circuit Breakers

For an AC-powered SES, verify that the shelf's power comes from dedicated AC branch circuits. The circuits must be protected by a dedicated, 15 Amp circuit breaker. Cisco Systems recommends that the site have a 15 Amp AC circuit breaker with a long trip-delay at each branch circuit.

DC Power Circuit Breakers

For a DC-powered SES, verify that its power comes from a dedicated DC branch circuit. This branch circuit must be protected by a dedicated circuit breaker. Cisco Systems recommends the site have a dedicated 30 Amp circuit breaker with a medium trip delay at each branch circuit.

A DC-powered SES uses a 30 Amp circuit breaker with a short trip delay on each -48V input.

Electrical Power for AC Units

The SES AC power requirement is a voltage range of 100 to 120 or 200 to 240 VAC. A worst case 90 VAC is allowed. Refer to Appendix A, "Technical Specifications." An AC power source must be available within 6 feet (1.8 m) of the system and easily accessible. Before turning on the power, verify that each power source to the SES comes from a dedicated branch circuit.

The power receptacles to which the node connects must be of the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth at the service equipment.

Cisco can provide AC power cords with the following plugs:

Electrical Power for a DC-Powered SES

Only an 48 VDC supply that complies with the Safety Extra Low Voltage (SELV) requirements of EN 60950 can connect to the DC input.

For DC supply connections, consult local or national codes for conductor sizing. Conductors must be suitable for 30 Amps. Wiring that is 10 AWG (4 square millimeters) is adequate.

Bonding and Grounding

To maintain the full EMI and EMC integrity of this equipment, it must be bonded to an integrated ground plane or an isolated ground plane network. The purpose of this requirement is to mitigate the damaging effects to equipment from electrostatic discharge and lightning. Refer to the latest edition of ITU Recommendation K.27 or Bellcore GR-1089-CORE requirements to ensure that the correct bonding and grounding procedures are followed. As recommended in these documents, a frame bonding connection is provided on the Cisco-supplied cabinet for rack-mounted systems.

Refer to the section "Making the Frame Bonding (Ground) Connection" in the IGX or the BPX installation documents for information on how to make a connection.


Note Except for the AC power supply module, every module in a rack-mount system relies on the rack itself for grounding. Therefore, the rack must be properly connected to protective earth before operating the system.

A DC-powered node must have grounding conductors that connect at two separate locations, as follows:

Telecommunications Requirements

The following telecommunications requirements may be relevant to a private network connected to the public switched networks in some international service areas: you must attach cables so that their securing bolts are tightened to the degree that removing the cable requires a tool.

Installing an SES

This section includes the following subsections:

Installing Processor and Service Modules

The SES is shipped from the factory with all cards and modules tested and installed. During initial installation, however, you may have to remove some of the service modules, the AC Power Supply Modules, or the Fan Tray Assembly to be able to more easily maneuver the SES chassis into place. Cisco recommends not removing the SES-PXMs. Before removing any modules or assemblies, Cisco suggests that you carefully note and write down their location or slot number in the chassis.

Using the Electrostatic Wrist Strap

The SES switch ships with a wrist strap for grounding the user and protecting the electronic components from electrostatic shock. The wrist strap kit consists of a strap, a coiled cord, and a clip for holding the strap.

The wrist strap can be connected to the SES chassis on the lower rear corner near the grounding lug, or to a convenient place on the front panel.


Caution To prevent damage to the cards from static electricity, put on a wrist strap and connect it to any convenient metal contact on the switch before you touch any cards.


Caution Do not drop or bump the SES-PXM. Handle the SES-PXM front card very carefully because it contains an attached disk drive.


Caution Inserting the cards in the correct slot is important for all cards but especially for the back cards because of the potential for electrical damage. If you insert a service module back card into a SES PXM back card slot (1 or 2), damage to the card and backplane can result. Never remove or insert either card in a PXM/SONET back card set with the power on.

If you accidentally try to insert a service module back card into slots 1 or 2, then observe incorrect switch operation, check for bent or damaged pins on the backplane and the back card.


Note Both the front card and the back card of all card sets in the shelf must be present for proper operation of the SES.

If a back card is removed and reseated or changed for another back card, the associated front card must be reset.

Removing and Installing the Front Cards

SES front (and back) cards are horizontally mounted. When seated, SES front cards are retained by a mechanical latch attached to the card. The top of a front card corresponds to the left side of the SES card cage as seen from the from the front, as shown in Figure 2-1.


Caution Before removing an SES-PXM from an operational system, execute the syncdisk and shutdisk commands.


Caution If you allow a front card to droop when you are inserting it in a card slot, you could damage components on the bottom of the card when you slide it in or out. When inserting or extracting an SES front card, make sure that you support the faceplate to keep the card level until it is completely inserted or extracted from the chassis.


Figure 2-1: Front Card Insertion/Extractor Lever


To remove a front card:


Step 1 Insert a small flat head screwdriver into the slot in the insertion/extractor lever and press until the latch springs open, approximately 10°. (There are two levers, on the left and right side, or top and bottom, on double-height cards.) Pull/rotate the insertion/extractor lever to disconnect the card from the backplane.

Step 2 Gently pull the card out of the card cage.


Caution To prevent damaging components on the bottom side of the card, make sure that you support the face plate and the card remains level while you are pulling it out of the chassis.

To install a front card:


Step 1 Be sure the extractor is in the unlatch position.

Step 2 Position the rear card guides over the appropriate slot at the left (top) and right (bottom) of the card cage.

Step 3 Gently slide the card all the way into the slot and then press/rotate the insertion/extractor lever (or both levers on double height cards) until it (or they) snaps into the vertical position.


Caution To prevent damaging components on the bottom side of the card, make sure that you support the face plate and the card remains level while you are sliding it into the chassis.


Note The card should slide in and out with only slight friction on the adjacent board's EMI gaskets. Do not use force. Investigate any binding.

Removing and Installing the Back Cards

Back cards are retained with two captive screws: one at the top of the faceplate and one at the bottom of the faceplate.

To remove a back card:


Step 1 Label and remove any cables connected to the back card.

Step 2 Use a screwdriver (flat or phillips as applicable) to undo the two retaining screws in the back card's faceplate.

Step 3 Pull both of the two extractor levers out to the horizontal position, this will start the removal of the card. Gently pull the card out of the card cage.

To install a back card:


Step 1 Ensure the two extractor levers are rotated to the "in" position. When the card is being inserted into the slot, the levers should be horizontal along the line of the back card.

Step 2 Position the rear card edges over the appropriate guides at the left and right sides of the SES card cage.

Step 3 Gently slide the card all the way into the slot and push to seat the card.

Step 4 Alternately tighten the two captive screws on the back card's faceplate.

Tighten the right and left captive screws in increments to prevent misalignment of the card. Do not overtighten the screws, but secure the card.


Warning Cards must be inserted in the correct slot positions. This is particularly true with back cards. If service module back cards are inserted into slots intended only for SES PXM backcards, slots 1 and 2, damage can be done.

If you accidentally attempt to insert a service module back card into slots 1 and 2 and have difficulty in operating the shelf, examine the backplane pins and the backcard connector to see if they have been bent or damaged.

Rack Mounting the SES

The SES is shipped with all the ordered modules installed and tested at the factory. If you've ordered an AC power option, the AC power supply tray is attached to the bottom of the SES chassis at the factory. To make the unit lighter for installation, Cisco advises you to remove the service modules (but leave the SES-PXM processor modules installed), fan tray assembly, and AC power supply modules before installing the SES.

When you install an SES, keep the following in mind:

    1. Due to the presence of a disk drive on each SES Processor Switching Module (SES-PXM), leave the SES-PXMs in place if possible. If you remove a SES-PXM, handle it with caution to preserve disk alignment.

    2. Even with all cards removed, the weight and bulk of the card cage mandate that three or more people install it. Alternatively, one person with a mechanical lift can install the SES.

    3. Two installers can support and maneuver the SES while a third secures it to the rack.

    4. Attach rear- or mid-mounting brackets before installing the SES in a rack.

Co-Locating Cisco Units in the Same Rack

Different Cisco products can reside in the same rack. An SES is typically co-located and rack-mounted with either an IGX switch, when it used as an IGX feeder, or with a BPX switch, when it is used as a PNNI controller. Appendix C, "Cisco Cabinet Configurations" illustrates some of the common configurations of Cisco WAN switching equipment in a Cisco-supplied rack.

Rack-Mount Positions

An SES is designed to be mounted flush with the front rails of the rack or mid-mounted. When the SES is flush mounted with the front of the rack, it is often attached to two mounting rails on each side. When the SES is mid-mounted, it typically attached to only one intermediate rail on each side. The allowable positions for intermediate rails are shown in .

There are two mid-mount brackets in each rack-mounting kit. One mid-mount bracket fits on each side of the SES chassis. The mid-mount bracket is 12.25 inches (7 rack units) high and has cutouts along the flange that attaches to the side of the SES to allow air flow. The same mid-mount bracket is used for the AC or DC-powered SESs; thus for an AC-powered SES, with the optional AC power tray assembly attached underneath the SES chassis, the mid-mount bracket does not extend down to AC power tray assembly. There are some shorter screws included in the rack-mount kits for attaching mid-mount brackets; these shorter screws are included specifically for attaching the mid-mount bracket to the side of the SES chassis that has the Fan Tray Assembly. Longer screws can interfere with the spinning of the fans in the Fan Tray Assembly. The shorter screws can be used on both mid-mount brackets, however.


Figure 2-2: SES Mounting Rail Positions


A rack-mount kit can be ordered for either 19- or 23-inch racks:

These kits include rear and mid-mount brackets as well as the hardware for mounting the brackets to the SES chassis. Note that there are extra #10 screws included in the 19-inch rack-mounting kit that can be used to secure the SES to the rack mounting rails. Since racks often have metric or non-standard threaded holes, you must supply the screws appropriate for your rack that attach the SES to rack mounting rails.

In each 19-inch rack-mounting kit, there are two sets of rear brackets; one set for each side. As shown in Figure 2-3, one bracket fits on the top at the rear of the SES, and the other fits on the bottom. There is a little bend in the bracket that fits over the top (or bottom) of the SES chassis. The other set of brackets fits on the other side of the SES chassis.

Rack Mounting Procedures


Caution The SES weighs 120 lbs to 150 lbs (54 kg to 68 kg) depending upon the number of installed cards. Have two persons, one each side, lift the SES into the rack, or use a lift.

Following these steps to mount an SES in a 19-inch rack.:


Step 1 If applicable, attach 1 mid-mounting bracket to each side of the SES.

Step 2 Use a lift or have two people position the SES into the rack.

Step 3 Use the #10 truss head screws to secure the SES to the front mounting rails (or mid-mounting rails if appropriate).

Step 4 Use the #10 screws to secure the SES to the rear mounting rails and to the rear mounting bracket, if applicable.

Follow these steps to mount an SES in a 23-inch rack.:


Step 1 Attach the 23-inch mounting brackets to both sides of the SES chassis, as shown in
Figure 2-5.

Step 2 Use a lift or have two people position the SES into the rack.

Step 3 Using hardware that you supply, and is appropriate for your 23-inch rack, secure the SES to the rack mounting rails.

Connecting Power for DC Systems

DC power is connected to one or two DC PEMs located on the SES chassis rear panel. You must supply the wiring from the DC source(s) to the DC PEM(s). The wiring should be 10 AWG (4 sq. millimeters).


Warning Be sure the power to the shelf is OFF at this point. DO NOT apply power until later.

To connect DC power to a DC SES, follow these steps:


Step 1 Locate the DC power entry module(s) on the rear panel of the SES.

There will be 1 or 2 DC PEMs installed and shipped with your SES according to your order. Figure 2-6 illustrates the rear panel of an SES with two DC PEMS, and Figure 2-7 illustrates the rear panel of an SES with one DC PEM.


Figure 2-6: Rear View of SES with Two DC PEMs



Figure 2-7:
Rear View of SES with 1 DC PEM


Step 2 Locate the pluggable terminal block (TB1) on the DC PEM to which you are connecting source power. Figure 2-8 is a rear view of a DC PEM showing TB1.


Figure 2-8: DC Power Entry Module, rear view




Step 3 Note the polarities of the TB1 connection points.

Figure 2-9 illustrates the polarity of each connection on the pluggable terminal block. The numbers start with 1 on the left and go to 3. The connection at the left is for the -48 VDC wire. The middle wire is Safety Ground. The connection at the right is for the positive return wire (for the -48 VDC).


Figure 2-9:
Polarities at SES PEM Pluggable Terminal Block


Step 4 Locate the wiring block for TB1. Figure 2-10 illustrates the TB1 wiring block (that is, the mating plug that attaches to TB1).


Figure 2-10:
Pluggable Terminal Block on SES PEM


Step 5 Insert and secure the stripped ends of the 10 AWG wire in the wiring block according to the scheme in Figure 2-9 and Figure 2-10 . Figure 2-10 shows the assembly with an example wire and the screw that secures it in the pluggable wire block.

Step 6 Attach the pluggable terminal block to the receptacle TB1 on the PEM.

Step 7 If you have a second DC PEM installed in your SES, repeat step 1 through step 6 for the second DC PEM.

Step 8 Connect the DC input wiring to a DC source capable of supplying at least 30 Amps (typical). The -48 VDC power source in the building should have a 30 A DC circuit breaker. The building's wiring should include an easily accessible disconnect device. Make sure the ground wire connects to a reliable building (earth) ground.


Warning For personnel safety, the green or green/yellow wire must connect to safety (earth) ground at both the equipment and at the supply side of the DC wiring.

Step 9 Before you turn on the system power, check the supply voltage.

The screws at positions 1 and 3 on the pluggable terminal block are convenient measuring points. Also, check the impedance between the safety ground (screw at location 2 on the pluggable terminal block) and the chassis. It should be close to 0.

Step 10 Turn on the source power, and check the voltage at the screws at positions 1 and 3 on the pluggable terminal block.

Step 11 Turn off the source power, and go to the section "Cable Management" which is followed by the section "Powering up the SES."

Connecting Power for AC Systems

This section describes how to connect AC power to an SES which has an optional AC power supply. The optional AC power supply tray is factory-installed on the bottom of the SES chassis. It is one rack unit high and can hold one or two 1200 Watt AC Power Supply Modules. Figure 2-11 illustrates a rear view of an AC Power Supply Module. Each AC Power Supply Module has its own independent connectors, Power switch, and LEDs.


Figure 2-11: Optional 1200 Watt AC Power Supply Module, Rear View


Each AC power supply module takes AC power and converts it to -48 VDC which is then routed through an external cable to the SES backplane connector. (There are no DC PEMs in an AC-powered SES.) In addition to supplying power, each power supply provides a signal that indicates the status of the power supply.


Note There must be at least two inches of empty space around the front and rear panels of the AC power supply for cooling air.

The rear panel of each AC Power Supply Module has:

The AC Power Supply Module front panel has both a DC OK LED and an AC OK LED.

Installing AC Power Supply Modules in the AC Power Supply Tray

The AC Power Supply Modules slide into the Optional AC Power Supply Tray from the rear of the SES. As seen from the front of the SES, AC Power Supply A (PSA) is on the left, and AC Power Supply B (PSB) is on the right. The front grill of the Optional AC Power Supply Tray has cutouts that allow the AC OK and DC OK LEDs on the front of the AC Power Supply Modules (PSA and PSB) to be seen from the front.

To install a 1200 Watt Power Supply Module in the AC Power Supply Tray, follow these steps:


Step 1 From the rear of the SES, slide a 1200 Watt AC Power Supply Module into the AC Power Supply Tray.

Step 2 Secure the set screw on the top of the AC Power Supply Module to secure it in the AC Power Supply Tray.

Step 3 Repeat step 1 and step 2 for the second 1200 Watt Power Supply Module if applicable.

If only one AC Power Supply Module is used in your system, make sure that the slot for the other AC Power Supply Module is covered with a blank faceplate.

Making the Connections to the AC Power Supply Module(s)


Step 1 Connect a cable supplied with your SES to the DC out connector on the optional AC power supply.


Note Without the DC cable connected to the SES backplane, the AC power supply will not power up. This is a safety feature.

The other end of this cable has a connector and a fixture for attaching to the SES backplane. (Note that there are not DC PEMs installed on an AC-powered SES.) The cable from the left AC Power Supply Module is connected to the connector on the left side of the SES backplane. Likewise, the cable from the right AC Power Supply Module is connected to the connector on the right side of the SES backplane.

Step 2 Use the appropriate AC power cord to connect the AC power source to the IEC receptacle(s) on the AC Power Supply Module.

Step 3 Make sure that the building AC receptacle is properly grounded.

Step 4 Repeat steps 2 through 3 for the second AC Power Supply Module if appropriate.

Figure 2-12 illustrates a SES chassis with 2 AC Power Supply Modules connected to the SES backplane.

Figure 2-13 illustrates an SES with one AC Power Supply Module connected to the SES backplane. If only one AC Power Supply Module is used in your SES, make sure that there are blank face plates covering the slots for the second AC Power Supply Module and the opening where the DC PEM would otherwise be installed.

In order for the AC power supply to function the enable switch must be in the "On" position, and the DC cable must be connected between the AC power supply connector and the SES backplane. Proceed to the section "Cable Management" which is followed by the section "Powering up the SES."


Note An AC power module will not power on if the DC cable is disconnected from the SES backplane.

Cable Management

A fully loaded SES may have many cables attached to the rack's modules. Cable management kits are available for installation on the rear of rack modules. These kits provide the means to route the power and data cables in a neat and orderly fashion to and from the modules in the SES. The cable management system is shipped with attaching hardware along with your SES.

Install the cable management brackets after a rack mounted unit has been installed in a rack, or a standalone SES has been positioned. Figure 2-14 illustrates an installed cable management system. When installing the cable management system on a rack-mount SES, the screws securing cable guides to the SES chassis are inserted from the outside in to the captive nuts in the chassis. When installing the cable management system in a standalone SES, the screws securing cable guides to the SES chassis are inserted from the outside to the captive nuts in the chassis.


Figure 2-14: Cable Management System on Rack-Mount SES


The cable management system provides the following features:

Powering up the SES

Before applying power to the SES, check the following items:

    1. Switch has proper grounding.

    2. AC or DC power sources are correctly installed.

    3. All cards are locked in the correct slots.

    4. All cables are secure.

    5. Control terminal is connected to the Console Port on the PXM-UI backcard. (See the "Service Expansion Shelf Feeder" appendix in the Cisco IGX 8400 Series Installation and Configuration document for release 9.2.)

After the preceding checks, turn on the power. Check the following:

    1. At the front of the unit, the status light on the PXM should be green.

    2. For an AC-powered system, the "AC" and "DC" LEDs on each AC Power Supply Module, as applicable, should be green.

    3. For a DC-powered system, the "DC OK" LED on DC PEM should be on.

    4. After each service module comes up, the status LEDs on each should show that it is in standby.

    5. When power is turned on, make a visual check to verify that all fans are running.

    6. After the system comes up, execute the dsppwr command.
