Complete the following steps to measure the rack space:
Step 1
Use Table 5 to calculate the rack space necessary for your Cisco 6100 system configuration. The total
amount of rack space should not exceed 42 RUs. If your total configuration exceeds 42 RUs, either
replan your configuration or use more than one rack to house the Cisco 6100 Series
system components.

Instructions
1
Total number of Cisco 6100 chassis in the rack—Maximum is two chassis per rack (including
subtending host and subtended node chassis).
2
Total number of fan trays in the rack—Used when installing either dual-port DMT-2 ATU-C or
quad-port flexi ATU-C modules in the chassis.
3
Total number of POTS splitters in the rack.
4
Multiply 9 RUs by the total number of chassis on line 1.
5
Multiply 3 RUs by the total number of fan trays on line 2.
6
Multiply 4 RUs by the total number of POTS splitters on line 3.
Add lines 4 through 6 for the total number of RUs needed with your Direct Connect with a POTS
7
splitter configuration using Cisco 6100 chassis.
1. This amount includes the 1 RU of space necessary for an intake plenum and cabling back to front for the OC-3c network interface module.
Determine if you need to prepare the rack to accommodate the fan tray and install the thermal guard.
Step 2

Disconnect ViewRunner
If you need to prepare the rack to accommodate the fan tray and install the thermal guard, you will need
to complete the following steps to disconnect the ViewRunner system:
Open the optional rear door, if your system has one.
Step 1
Step 2
Use a Phillips-head screwdriver to remove the two backplane screws that hold the plastic ESD shield
over the system I/O card. Keep these backplane screws and the plastic ESD shield for use when you
reconnect the ViewRunner system.
Disconnect the ViewRunner system from the Cisco 6100 by removing the Ethernet cable from the
Step 3
RJ-45 connector on the system I/O card.

If one or both of the following conditions is present, go to the following subsection:
The POTS splitter is not installed at the bottom of the rack and 3 RUs of space is not available
–
between the Cisco 6100 and POTS splitter.
The Cisco 6100 Series system is installed in a side-by-side rack configuration.
–
If you have sufficient space available in your rack configuration, the POTS splitter is installed at
the bottom of the rack, and your system is not installed in a side-by-side rack configuration, go to
the "Disconnect the Cisco 6100 Power Connections" section on page 15.
