Disconnect Cables From the Server
Caution:
The system supplies Standby power to the circuit boards even when the
system is powered off.
1. Label all cables connected to the server.
2. Power down the server.
See Powering Down the Server.
3. Disconnect the power cords from the rear of the server.
4. Disconnect all data cables from the rear of the server.
5. If your rackmount kit includes a cable management device, remove the cables
from it.
6. Depending on the components that you are servicing, either extend the server to
the maintenance position, or remove the server from the rack.
Stabilize the Rack
Caution:
To reduce the risk of personal injury, stabilize the rack cabinet, and extend
the anti-tilt bar before you install the server.
Refer to your rack documentation for detailed instructions for the following steps.
1. Open and remove the front and back doors from the rack cabinet, only if they
impinge on the mounting bay.
2. To prevent the rack cabinet from tipping during the installation, fully extend the
rack cabinet anti-tilt bar, which is located at the bottom front of the rack cabinet.
3. If the rack includes leveling feet beneath the rack cabinet to prevent the rack from
rolling, extend these leveling feet fully downward and lock to the floor.
Caution:
When moving the rack cabinet to a new location, verify that the leveling
feet are up before moving the rack.
