Adding Cisco 6100 Hardware

There are two main ways to physically expand the Cisco 6100 hardware after its initial installation:

add modules to an existing chassis
add chassis to the rack and add modules to the new chassis

When initially setting up the 6100, you might want to consider whether or not you plan to expand your system in the near future. At the current time, the Digital Off-Hook (DOH) standard configuration requires installing the multiplexer chassis (MC) at the top of the rack followed by one or more line concentration chassis (LCCs) followed by one or more POTS splitter chassis (PSCs). Therefore if you plan to add any LCC and/or PSC, consider leaving space in the rack during the initial install.

See the ViewRunner for Windows Provisioning and Operation Manual for information on provisioning additional chassis and/or modules.

10.1 Adding Modules to an Existing Chassis

There are no special considerations for adding ATU-Cs, line interface modules (LIMs), or POTS splitter modules to previously installed chassis. LEDs on the front of the modules should signal connection problems (should there be any).

See the ViewRunner for Windows Provisioning and Operation Manual for information on provisioning additional chassis and/or modules.

10.2 Adding an LCC and Modules

The following describes the steps necessary for expanding the 6100 by adding an LCC chassis to the rack and then modules to the new chassis. These steps are listed in the proper order of execution.

1. Add the LCC to the rack

2. Ground the new chassis to logic ground on the LCC above it

3. Change the DIP switches (particularly switches 5 and 6 to OFF) on the last LCC, then set them on the new LCC (switches 5 and 6 to ON for termination)

4. Cable the new LCC to the LCC above it

5. Connect power to the chassis without the fuse in place

6. Add/Replace the 1 amp fuse in the fuse/alarm panel

7. Add the LIM controller to the chassis

8. Add the new LIMs

If these steps are done in the proper sequence, adding an LCC and PSC can be accomplished without impacting existing user traffic. The key is to wire the new (empty) chassis without cards installed, then install the LIM controller, followed by the LIMs (one-by-one), and finally the POTS modules.

Caution Do not "hot swap" the LIM controller when any of the LIMs are still installed in the system. You must remove all LIMs before installing the LIM controller. You can, however, remove the LIM controller without removing all LIMs.

10.3 Adding a PSC and Modules

The following describes the steps necessary for expanding the 6100 by adding an PSC and then modules to the new chassis. These steps are listed in the proper order of execution.

1. Add the PSC to the rack (one for every new LCC)

2. Ground the new chassis to the rack or ground lug

3. Cable the new PSC to the new LCC

4. Add the new POTS modules
