Quad-Port Flexi ATU-C to Octal-Port DMT ATU-C Line Card Conversion Procedures
Remove the Power
Complete the following steps to remove power from the Cisco 6160 system:
Step 1 Type the following command to save the configuration changes to NVRAM:
DSLAM# copy running-config startup-config
Step 2 Set the circuit breakers on the power entry modules (PEMs) to the OFF (0) position.
Measure the Rack Space and Prepare the Rack
When upgrading your system from 4xflexis to 8xDMTs in a Cisco 6160 with a POTS splitter
configuration, you may have to move the hardware components in the rack to accommodate a
second POTS splitter as necessary. See the “Configuration Requirements” section on page 2 for
additional information.
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.
Complete the following steps to measure the rack space and prepare the rack:
Step 1 Use Table 3 to calculate the rack space necessary for your Cisco 6160 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 6160 system components.
Step 2 Connect a grounding strap to an ESD grounding jack on the chassis.

Total number of Cisco 6160 chassis in the rack—Maximum is four chassis per rack (include
subtending host and subtended node chassis).

in the rack.
1. A third-party POTS splitter must be used in a Cisco 6160 with a POTS splitter configuration.

.
2. See the documentation that accompanied the third-party POTS splitter to determine the number of RUs required. One RU is equal to
1.75 inches (4.45 cm.).
4
Multiply 11 RUs by the total number of Cisco 6160 chassis on line 1.
5
Multiply line 2 by line 3 to determine the total POTS splitter space requirement.
6
Multiply 1 RU by the total number of Cisco 6160 chassis on line 1

3. One RU is recommended for cabling needs and intake plenum.
7
Add lines 4, 5, and 6 to obtain the total number of RUs needed for a Cisco 6160 with or without
a POTS splitter configuration.
