Connecting cables to the chassis power supplies
This section describes how to connect the BIP power cables to the 8010co chassis
8004DC power supplies. These procedures assume that all required power
supplies were previously installed during the 8010co chassis installation.
Before beginning the procedures in this section, note the following:
• A 8010co chassis configuration can consist of one or two chassis in a single
rack. If a single chassis is installed, it is always installed in the lower shelf
position.
• Each chassis can be configured with up to three power supplies. The cabling
for each power supply comprises three conductors: the positive lead wire, the
negative lead wire, and the ground lead.
• To access the power supplies, you may have to remove the bottom front bezel
from both the upper shelf and lower shelf 8010co chassis.
Note: This guide does not describe how to remove or replace power
supplies in the 8010co chassis. For detailed instructions about adding
power supplies or modifying an existing configuration, see the
appropriate product chassis installation manual.
Note: For a single chassis installation, always install the chassis in the
lower shelf position to stabilize the rack.
Warning: Ensure that the DC power source is off or disconnected at the
remote end before you perform any of the steps in this section. You may
need to switch a circuit breaker off or turn off power at the DC input
source. Be sure that the DC input source power is locked out and tagged.
Note: The 321325-A bezel does not need to be removed to access the
power supplies.
