Disconnect the power cords and I/O cables
This procedure is used to disconnect the system from electrical power and disconnect
the peripherals.
Note
Before performing the following steps, ensure that the system is prepared for
removal. Use the management GUI to ensure that the system is not visible.
Procedure
1. Label each power cord and I/O cable so you can easily identify them when you
need to plug them in to restore the system.
2. Unplug power cords from the power supplies and disconnect the I/O cables
from the system.
Extend the system from the cabinet
This procedure is used to extend the system from the cabinet so that the system
cover can be removed to access the internal FRU components, or used in removing
the system from the cabinet.
Note
When replacing hot-swappable components, ensure the system cables are long
enough to stay connected while the unit is extended.
Procedure
1. At the front of the cabinet, locate the two rocker switches on left and right side
of the system. Press the top of the rocker switches inward to release the
system from the cabinet.
If the rocker switches do not disengage the system, loosen the screw under
each rocker.
