HP Cluster Platform Server and Workstation Overview

2.4.4 Removing a Server from the Rack
To access internal components in the HP ProLiant DL360 G3 and G4 servers, you must first
power down the server and then remove it from the rack. All of the servers in the cluster are
secured to the rack on a sliding rail.
The front panel power button on the HP ProLiant DL360 G3 and G4, , as shown in Figure 2-15,
toggles power between on and standby. If you press the Power On/Standby switch (callout 2)
to power down the server, the Power On/Off LED changes from green to amber, indicating
standby mode. In Standby, the server removes power from most electronics and drives, portions
of the power supply, and some internal circuitry remain active. If you press the Unit Identification
switch on the front panel (callout 1), an LED illuminates blue on the server front and rear panels.

To completely remove all power, disconnect the power cord first from the AC outlet and then
from the server.
When performing this task, heed the warnings and cautions listed in Section .
To remove a server from the rack without shutting down the entire cluster, as shown in
Figure 2-17, follow these steps:
1. Power down the server.
2. Disconnect all remaining cables on the server rear panel, including cables extending from
external connectors on expansion boards. Make note of which ethernet and interconnect
cables are connected to which ports.
3. Loosen the thumbscrews securing the server to the rack (callout 1).
4. Slide the server out of the rack until the rail locks engage.
5. Press and hold the rail locks (callout 2), extend the server until it clears the rack.
6. Remove the server from the rack and position it securely on a workbench or other solid
surface for stability and safety.
