General Maintenance Guidelines

This section covers the following topics:

Installation and Replacement Suggestions

The following examples list recommended installation and replacement practices for the Cisco 6015 system modules.

Caution Any module that is only partially connected to the backplane can disrupt system operation.

Do not force the module into its slot. This action can damage the pins on the backplane if they are not aligned properly with the module.
Ensure that the module is straight and not at an angle when you install the module in the slot. Installing the module at an angle can damage the module. Use the guide rails to install the module correctly.

Hot Swapping Modules

The DSL interface module is a FRU; however, it is not hot swappable. Removing the DSL interface module will interrupt the service for the entire system until it is replaced.

Caution The DSL interface module must be installed and removed by a trained technician only.

Preventing Electrostatic Discharge Damage

Proper ESD protection is required whenever you handle Cisco equipment. ESD damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Use an antistatic strap when you handle any card or component.

Tip Use the ESD grounding jack on the fan module for all maintenance except when you are removing the fan module. Use the ESD grounding jack on the DC PEM when you are removing the fan module.

Follow these guidelines to prevent ESD damage:

Always use an ESD ankle or wrist strap and ensure that the wrist strap makes good skin contact.
Connect the equipment end of the strap to the ESD grounding jack. There are two ESD grounding jacks that are located on the following Cisco 6015 chassis modules:
- Fan module
- DC PEM
When you install a component, use available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help ensure that bus connectors are properly seated.
When you remove a component, use available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.
Handle the modules by the extraction handles only; avoid touching the printed circuit boards or connectors.
Place a removed component board-side-up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.
Avoid contact between the printed circuit boards and clothing. The wrist strap protects components from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

Caution Periodically check the resistance value of the antistatic strap. Ensure that the measurement is between 1 and 10 megohms.

Removing and Installing the DSL Interface Module

The following sections describe how to remove or install a DSL interface module.

Removing the DSL Interface Module

Note If you are using AC power and the power cord is plugged in to the wall outlet, unplug it.

If you are using DC power and the fuses are already installed in the fuse and alarm panel, remove them. You can replace the fuses after the system is installed and connected.

The fuse and alarm panel is not provided by Cisco.

Tip Cisco recommends that you label each data cable at both ends to identify its destination.

Complete the following steps to remove the DSL interface module from the Cisco 6015 chassis:

Step 1 Connect a grounding strap to the ESD grounding jack that is located on the fan module.

Step 2 Set the circuit breaker on the DC PEM to the OFF (0) position.

Step 3 Disconnect the two Champ connector cables from the front of the DSL interface module.

Step 4 Use a flat-head or Phillips-head screwdriver to unscrew the four screws that hold the DSL interface module to the Cisco 6015 chassis.

Step 5 Hold the extraction handle on the front of the module and firmly pull the module out of the slot.

See the "Installing the DSL Interface Module" section for DSL interface module installation procedures.

Installing the DSL Interface Module

Step 4 Hold the extraction handle on the front of the module and gently apply pressure while carefully pushing the module into the slot.

Step 5 Push on the faceplate of the module to fully seat the module.

Step 6 Use a flat-head or Phillips-head screwdriver to attach the four screws to the Cisco 6015 chassis.

Step 7 Connect the DSL interface module to the POTS splitter (Cisco 6015 with a POTS splitter configuration) or MDF (Cisco 6015 without a POTS splitter configuration).

Use the cables that are described in the "Part and Tool Requirements" section to connect the DSL interface module to the POTS splitter or MDF. For cabling procedures for each POTS splitter, refer to the appropriate vendor documentation.

Note If unshielded cable is used for FCC Class A or EN55022 Class A compliance, the cables will need to be looped through ferrites.

Figure 4 shows the cabling between the DSL interface module and a third-party POTS splitter. These connections are for xDSL data flow between the Cisco 6015 and the POTS splitter.

Figure 4: Connecting the DSL Interface Module to the POTS Splitter

A system configuration using octal-port xTU-C line cards requires the installation of an additional POTS splitter. The additional POTS splitter expands the system capacity to 48 subscriber ports. Figure 5 shows the cabling between the DSL interface module and two third-party POTS splitters. These connections are for xDSL data flow between the Cisco 6015 and the POTS splitters.

Figure 5: Connecting the DSL Interface Module to Two POTS Splitters
