Apple Xserve G5 - Manual (Page 4)

2 - Xserve G5 Take Apart General Information
Tools
You will need a medium and a small Phillips screwdriver and a small flat-blade screwdriver
for some procedures. If the server is locked, you will also need the server’s Allen wrench
key.
Note: Many take-apart procedures do not require tools.
Server Identifier Light/Button
The identifier light on the server’s front panel turns on when internal sensors or a systems
administrator detects a problem with the server. (The light can also be turned on by
pressing the identifier button.) This indicator will help you locate which server in a rack
needs servicing. In addition, you can use the identifier button to initiate several firmware
commands to the system. See “Entering Firmware Boot Commands From the Front Panel”
in the Troubleshooting chapter.
Note: A duplicate identifier light/button is on the server’s back panel.
Before Opening the Server
Serial Number
Be sure to write down the server’s serial number. If the server’s software must be set up
after service is complete, the serial number will be required for login.
Unlocking the Server
If the server is in the locked position (the yellow security LED on the front panel is on), use
the Allen key that came with the server to unlock it.
Important: When the lock on the server’s front panel is locked, the software ignores the
optical drive, keyboard and mouse, and other peripherals connected to the USB and
FireWire ports on the server.
Shutting Down
You must shut down the server before replacing or installing all parts except the hard
drives. Before shutting down, be sure to alert users that the server will be unavailable for a
period of time.
Warning: After shutting down the server, you must wait a few minutes before servicing it
to allow internal components to cool.
