 | Warning Only trained personnel should install, replace, or service this equipment. |
This chapter provides procedures that you can use to install a Cisco 6130 NI-2 DSL access multiplexer (DSLAM) without a POTS splitter.
For detailed information on the following, refer to the Cisco 6130 DSLAM with NI-2 User Guide:
A DSLAM installation without a POTS splitter can include the following components:
In an installation without a POTS splitter configuration, the chassis connects directly to the main distribution frame (MDF).
For additional compliance and safety information, refer to the Regulatory Compliance and Safety Information for the Cisco 6100 Series System document.
| Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. |
Figure 5-1 shows the components for an installation without a POTS splitter configuration, which is designed for a dedicated, one-to-one configuration.
If you are installing more than one chassis in a configuration without a POTS splitter, install a fan tray under each chassis.
The chassis ships with a front door that must be installed and in place for the system to achieve NEBS compliance (see Figure 5-2).
For more information on NEBS requirements, refer to the Regulatory Compliance and Safety Information for the Cisco 6100 Series System document.
Installation of a rear door is optional. See the "Install the Rear Door (Optional)" section for installation information. Refer to the Cisco 6100 Series Rear Door Configuration Notes for additional product information.
When you install a Cisco 6130 NI-2 DSLAM without a POTS splitter, be sure that you follow the installation procedures in proper sequence. Table 5-1 lists the installation steps in the order in which they should occur. Subsequent subsections describe the installation steps.
| Caution Proper ESD protection is required whenever you handle Cisco DSL access multiplexer (DSLAM) equipment. Installation and maintenance personnel should be properly grounded using ground straps to eliminate the risk of electrostatic discharge (ESD) damage to the equipment. Modules are subject to ESD damage whenever they are removed from the chassis. |

For the rack to remain stable, you must install your Cisco 6130 system(s) from the bottom to the top of the rack. Before you install any chassis, determine how much rack space you need. The rack space required depends on the number of chassis and fan trays you plan to use.
You can install a combination of the following Cisco 6130 components in a 7-foot rack:
The Cisco 6130 system fits in a 23-inch wide rack. Allow enough space for wiring. See Table 2-1 for rack space requirements. Allow 1 RU of space under the fan tray. This space is for the intake plenum and for cabling back to front for the OC-3c NI-2 module.
| Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: |
If you plan to expand your system to include more chassis in the future, allow space in the rack for additions during the initial installation, keeping in mind the weight distribution and stability of the rack.
You are installing a Cisco 6130 chassis in this configuration; therefore, you must have a fan tray installed directly below the chassis. You must install the fan tray to achieve NEBS compliance.
Use the following steps to install the fan tray in the rack:
Step 1 Position the fan tray so that it is directly below the chassis (after it is installed). The top of the fan tray must be flush with the bottom of the chassis. Allow 1 RU of space beneath the fan tray. This space is for the intake plenum and for cabling back to front for the OC-3c NI-2 module.
Step 2 Using the four mounting screws and a Phillips-head screwdriver, bolt the fan tray in the rack below the chassis.
See Figure 5-1 for the correct placement of the fan tray.
The system I/O card is shipped with the Cisco 6130 NI-2 DSLAM in a kit that includes the components listed in Table 5-2.

The Cisco 6130 NI-2 DSLAM (chassis) is not shipped with the system I/O card (see Figure 5-3) installed, because the system I/O card is a field-replaceable unit and is packaged in the system I/O card installation kit.
Before you can operate the Cisco 6130 NI-2 DSLAM, you must install the system I/O card. During this initial installation, you mount the system I/O card on the chassis backplane, using the components from the installation kit, which is shipped with the chassis.
The installation kit consists of the following components:
The EMI shield is formed by the EMI fence (see Figure 5-5), which is soldered in place on the system I/O card, and the EMI cover (see Figure 5-5), which is held in place on the EMI fence with a kit screw installed through the EMI cover and into the EMI cover bracket (see Figure 5-6). The EMI cover bracket is held in place by two kit screws installed in the two underlying standoffs between receptacles P9 and P3. Printed circuit board fuses, relays, and surge protectors are shielded by clear plastic covers held in place by kit screws installed in the provided standoffs. The EMI cover and protective shields must be in place during Cisco 6130 NI-2 DSLAM operation.
The initial installation of the system I/O card is carried out in two procedures. First, the system I/O card and its protective plastic covers are mounted on the chassis backplane. Next the EMI cover bracket, EMI cover, and system I/O card ESD shield are installed.
This section tells you how to do the initial installation of the system I/O card on the chassis backplane (see Figure 5-4).
| Caution Disconnect chassis power before doing the initial installation of a system I/O card. |
| Caution Static voltages as low as 30 volts can cause latent damage to circuitry on the system I/O card. Be sure to observe all standard antistatic procedures (for example, wear a grounding strap). |
Step 1 Check that a standoff is located at each of the chassis backplane standoff positions (see hexagonal standoffs in Figure 5-4 and Figure 5-5). Install any missing standoffs using those contained in the installation kit as replacements. Also check that all standoffs are tight.
| Caution Do not overtighten a standoff. Overtightening may cause the system I/O card printed circuit board to crack. |
Step 2 Remove the screw from the right side of the backplane ESD shield and standoff between receptacles J41 and J47 (see Figure 5-4). No standoffs, except the three holding the backplane ESD shield in place, should now have screws in them.
Step 3 Holding the system I/O card vertically with its component side toward you (see Figure 5-5), align its top right mounting hole with the top right standoff (above J48) on the chassis backplane. Ensure that this aligns connectors J3 and J9, on the system I/O card, with receptacles P3 and P9 on the chassis backplane.
Step 4 Carefully press connectors J3 and J9 into backplane receptacles P3 and P9 until the system I/O card is in place and against all its standoffs.
Step 5 Use three kit screws to loosely mount the system I/O card on the three chassis backplane standoffs at the right side of the system I/O card (see Figure 5-5).
Step 6 Holding the safety shield in place at the left side of the system I/O card, loosely install the safety shield and system I/O card. Use three kit mounting screws, inserting them in the three standoffs at the left side of the system I/O card (see Figure 5-3, Figure 5-4, and Figure 5-5).
Step 7 Loosely reinstall the screw removed from the standoff in Step 2 above. The system I/O card should now be situated over the chassis backplane ESD cover (see Figure 5-4).
Step 8 Loosely install a kit mounting screw in the standoff at the upper left hand corner inside the EMI fence (see Figure 5-5 and Figure 5-6).
Step 9 Install a standoff from the installation kit in the standoff between relays K4 and K5 on the system I/O card (see Figure 5-3 and Figure 5-6). Observing the overtighten caution, tighten the installed standoff.
Step 10 Remove the system I/O card ESD shield from the installation kit. Place the ESD shield, on the standoff you installed in Step 9, so that the hole in its top aligns with the hole in the standoff. The top edge of the ESD shield should lie parallel to, and against, the EMI fence (see Figure 5-6).
Step 11 Install a kit screw through the hole in the ESD shield and into the standoff you installed in Step 9 above. Observing the overtighten caution, tighten the screw and check all other screws for tightness.
The EMI cover (see Figure 5-3 and Figure 5-6) is installed on the chassis backplane after the I/O card is positioned on the chassis backplane. This section tells you how to install the EMI cover on the chassis backplane.
Step 1 Remove the EMI cover bracket (Figure 5-6) from the installation kit. Place the bracket over the system I/O card holes between receptacles P3 and P9.
Step 2 Remove two kit screws and install them through the holes in the EMI cover bracket and into the standoffs under the system I/O card. Observing the overtighten caution, tighten the screws.
Step 3 Remove the EMI cover from the installation kit, and mount it on the EMI fence.
| Caution Be careful not to bend the tabs on the EMI cover when you install the cover on the EMI fence. |
Step 4 After making sure that no EMI cover tabs are outside the EMI fence, install a screw through the EMI cover and into the EMI cover bracket. Observing the overtighten caution, tighten the screws.
Step 5 If required, replace or install the CO alarm wiring at the system I/O card alarm wire-wrap headers. See the "Connect the Alarm Contacts" section for a description of system I/O card alarm wiring.
Step 6 If required, replace or install CO system network trunk and subtending interfaces. See the "Connect the Network to the System I/O Card" section for a description of system network trunk and subtending interface connections.
Use the following steps to install the chassis in the rack.
Step 1 Position one chassis above the fan tray. The top of the fan tray should be flush with the bottom of the chassis.
Step 2 Using mounting screws and a Phillips-head screwdriver, bolt the chassis in the rack.
Step 3 Remove the chassis front door.
Step 4 Repeat Steps 1 through 3 for each chassis as necessary.
Step 5 Connect the Cisco 72-1912-01 SCSI cable between connector J1 on the fan tray and connector J49 on the chassis. You need to do that so the chassis recognizes the fan tray (see Figure 5-7).
See Figure 5-1 for the correct placement of the chassis.
| Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. |
| Warning When you are installing the units, the ground connections must always be made first and disconnected last. |
| Warning This equipment needs to be grounded. Use a green and yellow 14 AWG ground wire to connect the host to earth ground during normal use. |
During the system installation, use the following steps to connect the grounding lugs on the chassis and the fan tray directly to the rack.
Step 1 Remove all paint or oxidation from the rack at the point of the grounding connection.
Step 2 Measure enough wire (14 American Wire Gauge [AWG] or thicker green or green with yellow stripes stranded copper wire) to connect the chassis to the rack. (See Figure 5-8 for grounding wire location.)
Step 3 Use a wire stripper to remove the casing from both ends of each wire.
Step 4 Using a 3/16-inch flat-blade screwdriver, loosen the screw on the rack.
Step 5 Hook one end of the copper wire around the screw on the rack in a clockwise direction.
Step 6 Tighten the rack screw over the copper wire.
Step 7 Loosen the compression screw provided on the grounding lug on the chassis. The grounding lugs are located in the upper left corner of each chassis (viewed from the rear).
Step 8 Insert the other end of the copper wire under the compression screw.
Step 9 Tighten the compression screw over the copper wire.
Step 10 Repeat Step 1 through Step 9 for the fan tray.
Step 11 Connect a Cisco 72-1912-01 SCSI cable to SCSI connector J1 on the fan tray and to SCSI connector J49 on the chassis. You need to do this so that the chassis recognizes the fan tray (see Figure 5-1).
The left side of Figure 5-8 shows how to ground the chassis and fan tray to the rack.
| Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. |
Connect the 50-pin Champ cables from the chassis (J39 through J44) to the MDF. These connections are for xDSL data flow between the chassis and the MDF. See the "Installing Cables without a POTS Splitter" section for cabling diagrams and cable part numbers.
Figure 3-3 and Figure 5-9 show a typical current data connection configuration, as well as the xDSL data connection through the Cisco 6130 NI-2 DSLAM.
| Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. |
| Caution To prevent the system from powering up, do not install the fuses at this time. If the fuses are already installed in the fuse and alarm panel, remove them. You can replace the fuses after the system is wired. |
| Warning The power supply circuitry for the Cisco DSLAM equipment can constitute an energy hazard. Before you install or replace the equipment, remove all jewelry (including rings, necklaces, and watches). Metal objects can come into contact with exposed power supply wiring or circuitry inside the DSLAM equipment. This could cause the metal objects to heat up and cause serious burns or weld the metal object to the equipment. |
| Warning This unit has more than one power supply connection; all connections must be removed completely to completely remove power from the unit. |
External power is supplied to the system as -48 VDC from the central office (CO) power source or rectifier to the fuse and alarm panel. Power is fed from the fuse and alarm panel to the chassis by a terminal block connector with four dual-power connections (P13) located at the top of the chassis backplane. Figure 5-10 shows the location of the power connections (P13) on the chassis.
You can wire the power connections from the chassis to the fuse and alarm panel for either dual- or single-power feed.
Use the following steps to attach the chassis power connections (P13) to the fuse and alarm panel for a dual-power feed.

To achieve NEBS compliance, verify that the chassis front door is attached to the chassis and closed. See the "Close the Chassis Front Door" section in "Installing a Cisco 6130 NI-2 DSLAM with a POTS Splitter."
You can order and install an optional rear door for the back of the chassis. The rear door attaches to the back of the chassis and restricts access to the backplane and cable connectors. To keep cables from interfering with the opening of the rear door, the cables that come down from the top of the rack can be tie wrapped to the door-mounting brackets.
For instructions, see the "Install the Rear Door (Optional)" section in "Installing a Cisco 6130 NI-2 DSLAM with a POTS Splitter."
