Replacing the cable-management arm

Before you replace the cable-management arm, remove any devices that are directly above and below the
console unit so that you can disconnect the cables and detach the cable-management arm. See the
documentation that comes with the device for removal instructions.
You can also remove the console unit from the rack for easier access. See the instructions in "Removing the
console unit from the rack" on page 41; then, return to step Step 5 on page 32 in this procedure.
To replace the cable-management arm, complete the following steps:

If a console switch is installed behind the console unit, remove the console switch from the rack.
Step 2.
Turn off the display and disconnect the power cord from the short jumper cord on the cable-
management arm from the electrical outlet or power distribution unit (PDU). Disconnect from the
server or console switch any cables that are connected to the console unit (keyboard-and-mouse,
video, and power cables).
Step 3.
Close the flat-panel display.
Step 4.
Temporarily remove all cables from the cable-management arm.
Step 5.
