Install the POTS Splitter
Before you install the additional POTS splitter needed for a Cisco 6160 with a POTS splitter
configuration, you need to stabilize the rack for the new hardware components.
Verify that your Cisco 6160 system is installed from the bottom to the top of the rack so the rack remains
stable. If your system is not installed from the bottom to the top of the rack, make the necessary
adjustments to the rack.
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:
- This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
- When mounting this unit in a partially filled rack, load the rack from the bottom to the top with
the heaviest component at the bottom of the rack.
- If the rack is provided with stabilizing devices, install the stabilizers before mounting or
servicing the unit in the rack.
In a Cisco 6160 system with a POTS splitter configuration using 8xDMTs, it is necessary to expand the
system to accommodate 256 ports in one of the following ways:
• Install a 528 POTS splitter.
• Verify that a total of two 128 POTS splitters are installed in the rack.
Note For installation procedures for each POTS splitter, refer to the appropriate
third-party documentation.
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.
