Step 4 Connect the other end of the copper wire to earth ground.

Powe ring Up the Cisco ONS 15304

Warning Because the router does not contain a powe r supply or an ON/OFF switch, you are required to provide a controlled power source such as a rectifier or a DC circuit breaker. See "Safety Guidelines," for safety precautions and recommendations.

Warning Working with live circuits is dangerous. Before continuing, ensure that the power to the router is turned off and cannot be accidentally turned on. Use a multimeter to verify that power is not being applied to the router.

Warning Use only copper wire when connecting power to the router.

Warning Connect to a -48/60 VDC source that is electrically isolated from an AC source and reliably connected to earth.

Warning Care must be given to connecting units to the supply circuit so that wiring is not overloaded.

To connect power to the Cisco ONS 15304, you need one DC terminal block plastic shield and a number 2 Phillips screwdriver. Follow these steps:

Step 1 Make sure the power is switched off at the power supply before connecting the power feeds to the Cisco ONS 15304.

Step 2 Attach the -48/60 VDC red wire and the -48/60 VRTN (black wire) to the 48V A and B feeds (number 14 AWG minimum) to the terminal block of the Cisco ONS 15304.

Step 3 Find the plastic shield and number 2 Phillips screws in the accessory kit. Position the holes of the plastic shield on the terminal block. Use the number 2 Phillips screwdriver to attach the plastic shield and screws to the terminal block. See Figure 3-4 for screw location.

Figure 3-4: Location of t he Term inal Block on the Cisco ONS 15304

Step 4 Connect the other end of the power cord to the power source.

Step 5 Loosen the screws on the SAM ejectors with a number 2 Phillips screwdriver and pull the ejectors out about 4 inches.

Step 6 Turn ON the power at the power supply and verify that the voltages are 48V/60V for both A and B feeds.

Step 7 After verifying the voltages, grasp the ejectors, push the SAM back into place, and tighten the screws with a number 2 Phillips screwdriver.

Connecting a Terminal to the A sync Co nsole Port

To connect a terminal to the async console port of the Cisco ONS 15304, you need:

A VT-100 terminal or terminal emulator
EIA/TIA-232 cable (included)
RJ-45 connector (included)

Step 1 Remove the console cable and the RJ-45 connector from the accessory kit. Connect one end of the cable to the async port (labeled "ASYNC") on the front of the Cisco ONS 15304 (see Figure 3-5).

Note If you are using HyperTerminal, set the connection rate to 9600 baud and turn flow control off (or leave as none). Choose "none" for parity and "1" for stop bits.

Figure 3-5: Async Con sole Po rt on the Cisco ONS 15304

Step 2 Connect a cable adapter to the other end of the console cable. The type of adapter you use depends on the connector on your terminal.

Step 3 Connect the cable adapter to the terminal.

Step 4 Because the Cisco ONS 15304 has no power switches, turn on power to the Cisco ONS 15304 by following the procedure described in the "Powering Up the Cisco ONS 15304" section.

Logging In to the Cisco ONS 15304

To log in to the Cisco ONS 15304, you need a VT-100 terminal emulator.

Connecting a Terminal to the Ethernet LAN Management Port

The Cisco ONS 15304 supports two management ports on the front panel: an async console port (see the "Connecting a Terminal to the Async Console Port" section) and an Ethernet LAN port using an RJ-45 connector. This section describes how to configure and activate the Ethernet LAN management port.

To provision the Cisco ONS 15304 for management access, you need:

A VT100 terminal or terminal emulator if you want to watch the on-screen images as the Cisco ONS 15304 boots
Unshielded twisted pair (UTP) CAT 3 or CAT 5 cable (not included)
RJ-45 connector (not included)

Note If you are using HyperTerminal, set the connection rate to 9600 baud and turn flow control off (or leave as none). Set "none" for parity and "1" for stop bits.

To connect to the Ethernet LAN management port, you must configure it through the async console port. If you have not already accessed the Cisco ONS 15304 through the async console port, see the "Connecting a Terminal to the Async Console Port" section.

Step 1 Connect the CAT 5 cable to the LAN management port using an RJ-45 connector.

After typing each of the following commands, press the Enter key:

Step 2 Log in to the Cisco ONS 15304 using either the default username, admin, or a username created earlier. At the ONS> prompt, enter:
login username

Step 3 Enter configuration mode. At the ONS# prompt, enter:
configure terminal

Step 4 Enter interface configuration mode. At the ONS (config)# prompt, enter:
interface Ethernet 0

Step 5 Specify an IP address and activate the management LAN interface. At the ONS (config-if)# prompt, enter:
no shutdown
ip address interface_address subnet_mask

The LAN port is now ready for management access.

You might want to use an access list to protect against unauthorized access. To do this, first create an access list and then associate it with the management LAN interface. For more information on creating and assigning access lists, see the Cisco IOS Network Protocols Configuration Guide.

Cisco ONS 15304 LE D Indicators

The Cisco ONS 15304 displays various LEDs that indicate different operating conditions. For example, the SAM LED displays a green "Active" LED when the system is operating normally. See Figure 3-6 for the location of the LEDs on the system.

When you power up and boot the system, the Cisco ONS 15304 performs a power-on self test (POST). There are two types of POSTs: short and long. A short POST takes approximately 1 to 2 minutes; a long POST takes approximately 4 to 5 minutes.

While the POST is running, the Fault LED flashes red. When the POST is complete, the system reboots, and the Active, Standby, or Fault LED is lit, based on the actual operating state.

Figure 3-6 shows the Cisco ONS 15304 LEDs and buttons.

Figure 3-6: Cisco ONS 15304 LE D s

LED Power-On Sequence

After the Cisco ONS 15304 has booted and the POST is complete, both SAMs return to ROMMON, and the standby and fault LEDs flash on and off for approximately 5 seconds.

Next, the Cisco ONS 15304 reboots, resulting in the following LED status:

The active LED on the active SAM lights solid
The standby LED on the standby SAM lights solid
The free run LED lights solid
No other LEDs are lit except optical LEDs (red)

Lamp Test

The alarm cut-off (ACO) pushbutton, when pressed for two seconds, performs a lamp test on the Cisco ONS 15304.

System A larm LEDs

System alarm LEDs are provided to display critical, major, and minor system alarms. Table 3-2 lists the alarms and how to interpret them.

Table 3-2: System Alar m LEDs

Alarm LED Color Meaning

Critical alarm LED

Red

A severe service condition that requires immediate corrective action.

Major alarm LED

Red

A serious service condition that indicates a major disruption of service. This condition has a lesser effect on service or system performance than a critical alarm.

Minor alarm LED

Yellow

A condition that does not have a serious effect on service or operation.

Alarm	LED Color	Meaning
Critical alarm LED	Red	A severe service condition that requires immediate corrective action.
Major alarm LED	Red	A serious service condition that indicates a major disruption of service. This condition has a lesser effect on service or system performance than a critical alarm.
Minor alarm LED	Yellow	A condition that does not have a serious effect on service or operation.

Processor LED

A processor (PROC) LED is red when both processors (SAM A and SAM B) have failed.

ACO LED

An alarm cut-off (ACO) LED and pushbutton are provided at the front panel of the system. ACO functions as follows:

Press the ACO button to squelch any active alarm contact closures at the site alarms connector. This silences audible alarms at the site.
When you use the ACO button to squelch an alarm, the green ACO LED lights.
The green ACO LED goes out when the alarm being squelched is cleared or if a new alarm is posted by the system.

Table 3-3 describes the meaning of the ACO LED colors.

Table 3-3: ACO LE D

LED Color Meaning

Green

A green ACO LED means an audible alarm is being squelched because the ACO button has been pushed.

No color

No lighting of the ACO LED means that an alarm that was squelched has been cleared. It can also indicate that a new alarm has been posted by the system.

LED Color	Meaning
Green	A green ACO LED means an audible alarm is being squelched because the ACO button has been pushed.
No color	No lighting of the ACO LED means that an alarm that was squelched has been cleared. It can also indicate that a new alarm has been posted by the system.

SAM LEDs

SDH SAM LEDs are provided for quick assessment of SAM "health." They have the characteristics identified in Table 3-4.

Table 3-4: SAM Alar m LEDs

LED Name Color Meaning

ACTIVE

Green

A green ACTIVE LED means that SAM is currently the active SAM.

STANDBY

Green

A green STANDBY LED means that SAM is currently the standby SAM.

ACTIVE and STANDBY

Both are green

Green ACTIVE and STANDBY LEDs mean abnormal system behavior and a trouble situation.

FAULT

Red

A red FAULT LED indicates that an equipment failure occurred on that SAM. This LED does not light in relation to facility failures. It reflects only equipment failures within the particular SAM. Although SAM equipment failures can cause facility failures, generally, the FAULT LED is reserved for SAM equipment-related trouble.

LED Name	Color	Meaning
ACTIVE	Green	A green ACTIVE LED means that SAM is currently the active SAM.
STANDBY	Green	A green STANDBY LED means that SAM is currently the standby SAM.
ACTIVE and STANDBY	Both are green	Green ACTIVE and STANDBY LEDs mean abnormal system behavior and a trouble situation.
FAULT	Red	A red FAULT LED indicates that an equipment failure occurred on that SAM. This LED does not light in relation to facility failures. It reflects only equipment failures within the particular SAM. Although SAM equipment failures can cause facility failures, generally, the FAULT LED is reserved for SAM equipment-related trouble.

Timing LEDs

Timing LEDs indicate the timing source currently being used. The possibilities are optical line A, optical line B, external port A, external port B, FREE RUN, and HOLDOVER.

FREE RUN is a condition in which the network element is configured to use its internal timing source. FREE RUN is the default timing status if no timing source is configured. HOLDOVER is a condition in which the network element is configured to use an external timing source, but the source is bad or has failed. As a result, timing is now driven from the internal timing source based on the frequency acquired from the last good reference.

Timing status LEDs have the following characteristics:

Each SAM has LEDs for LINE A, LINE B, EXTERNAL A, EXTERNAL B, HOLDOVER, and FREE RUN. LINE A, LINE B, and EXTERNAL LEDs can be lit green when a reference is the current system reference and red when a reference goes into alarm. HOLDOVER and FREE RUN only light green.
A single green LED is lit on the active SAM to indicate where timing for that SAM is currently being received. The standby SAM LED indicators track to the active SAM indicators.

Table 3-5 describes the timing LEDs.

Table 3-5: Timing L EDs

Fan Tray Ala rm LED

The Cisco ONS 15304 uses three fans located in the fan tray. If a fan has a locked rotor, a fan failure detector signals the user with an alarm for that fan. The fan tray unit is hot swappable.

A fan alarm LED is provided for each fan on the front panel of the system. The red LEDs are labeled FAN ALARMS and each LED is labeled 1, 2, and 3.

If one fan tray LED is red, it is considered a minor, nonservice-affecting condition. If two or three fan tray LEDs are red, it is considered a major, service-affecting condition. The Cisco ONS 15304 can operate with one fan failure. However, it cannot operate with two or three fan failures. Therefore, if a fan fails, replace the fan tray as soon as possible.

Cleaning the Fiber-Optic Conne ctor Sleeve
and Patch Cord

Warning Avoid looking directly into fiber ends or optical connectors. Doing so could cause damage to your eyes.

To ensure optical performance of the SDH network, Cisco recommends cleaning the fiber-optic connectors on the fiber patch cords and equipment before installing or reinstalling the fiber patch cords into the Cisco ONS 15304 SAM. You need:

Noyes (test equipment vendor) or equivalent 200X or higher fiber scope. The scope is used for viewing the fiber to determine if additional cleaning is required or if damage has occurred to the ferrule of the fiber.
Isopropyl A1, reagent grade that is certified particle grade for cleaning fiber-optic cable.
Wipes pre-moistened with alcohol (Texwipe TX806) for cleaning the fiber-optic connector.
100% polyester wipe (Texwipe TX404) that is lint free, fiber free, and cleanroom certified. This is used for removing excess alcohol during cleaning.
Foam miniswabs (Chemtronics 48040) in a static/sterile package.
Number 2 Phillips screwdriver.

Note Contamination of fiber-optic connectors can be reduced by removing the Cisco ONS 15304 from its antistatic packaging only during installation. In addition, avoid removing the protective caps from the fiber cables and the equipment before installing the Cisco ONS 15304. To reduce contamination during installation, the fiber cable should be inserted immediately into the optic facility and the fiber patch panel.

Step 1 Attach an antistatic wrist strap to your wrist and plug the other end into the electrostatic discharge (ESD) jack on the Cisco ONS 15304.

Step 2 Loosen the screws on the Cisco ONS 15304 ejectors with a number 2 Phillips screwdriver and pull the SAM toward you. Remove the SAM from the Cisco ONS 15304 and place it on a clean antistatic surface.

Step 3 To clean the connector sleeve on the SAM, moisten a miniswab with alcohol. Use the miniswab to scrub the alignment sleeve lightly. See Figure 3-7 for the location of the alignment sleeve.

Figure 3-7: FC Fiber Conne cto r

Step 4 Use a dry miniswab to remove excess alcohol immediately. Do not allow excess alcohol to dry.

Note The position of the fiber connectors on the Cisco ONS 15304 can restrict thorough cleaning. If contamination still exists or signal degrade or excessive loss is recorded through the connector, replace the SAM.

Step 5 To clean the ferrule, place the end of the connector in a new cloth or a premoistened cloth and wipe the ferrule until clean.

Step 6 While still wet, wipe the ferrule dry using a new cloth (TX-806). If the ferrule is allowed to dry before all alcohol residue is removed, the unit might not operate properly.

Step 7 Insert the connector into a fiber scope to inspect the cleanliness of the fiber. If the connector is still dirty, repeat the fiber cleaning procedure or replace the fiber-optic patch cord.

Connecting Fiber-Optic Cab les to the Optical Facility

Caution The minimum be nd radius for fiber-optic cable is 1.5 inches. Observe this limit at all times. Failure to do so can result in damage to the fiber or degrade the optical signal.

To connect fiber-optic cables to the optical facility, you need:

Plastic clip for the fiber-optic cables (included)
Fiber-optic cables
Number 2 Phillips screwdriver

To attach the fiber-optic cables to the Cisco ONS 15304:

Step 1 Attach the white plastic clip (included in the accessory kit) to the left of the optical facility keyhole. This clip is used to secure the fiber-optic cable to the front of the SAM.

Step 2 To attach fiber-optic cables to a SAM, grasp the ejectors positioned under the SAM and partially pull the SAM out about four inches (see Figure 3-8).

Figure 3-8: Optical Facility and Ejector Loc at ion on the Cisco ONS 15304

Step 3 Grasp the fiber-optic cables with the thumb and forefinger of both hands and push them through the opening of the white fiber-optic cable clip. Insert the fiber-optic cables through the keyhole on the front left side of the SAM. (See Figure 3-9.)

Figure 3-9: Closeup View of Fib er-Optic Cable Clip and Keyhole Location

Step 4 After the fiber-optic cables are through the keyhole, carefully pull the cables and tuck them under the top front lip of the SAM at the same time. Thread the cables through until you reach the optical facilities on the right side of the SAM. See Figure 3-10 for the view from the back of the SAM.

Step 5 Test the receive level before plugging the fiber-optic cables into the Cisco ONS 15304. See Table 2-5 and Table 2-6 for transmitter and receiver specifications.

Figure 3-10: Fiber-Optic Cable Pos itionin g

Step 6 Attach the fiber-optic cables to the optical facilities as shown in Figure 3-10.

Step 7 After attaching the fiber-optic cables, grasp the ejectors and push the SAM into the Cisco ONS 15304. Tighten the screws on the ejectors with a number 2 Phillips screwdriver.

Caution Exceeding the maximum optical power input specifications of the Cisco ONS 15304 might cause permanent damage to the SAM.

Cisco recommends cleaning the fiber-optic connectors on the fiber patch cords and equipment if the input/output optical specification levels you have measured do not fall within the input/output optical specifications shown in Table 2-5 and Table 2-6.
