Installing the cable-management arm and connecting and routing power cables
The cable-management arm is used to efficiently route cables so that you have proper access to the rear of the system. After you install the cable-management arm, connect and route power cables.
About this task
Note: If you are installing more than one system now, install the cable-management arm after you
install the other systems into the rack.
Procedure
-
Ensure that you have the following parts.
Refer to Figure 1.
