3. Release the rack latches (C) on both the left and right sides, as shown in
Figure 3.
4. Review the following notes, and then slowly pull the system or expansion unit
out from the rack until the rails are fully extended and locked:
v
If the procedure you are performing requires you to unplug cables from the
back of the system or expansion unit, do so before you pull the unit out from
the rack.
v
Ensure that the cables at the rear of the system or expansion unit do not
catch or bind as you pull the unit out from the rack.
v
When the rails are fully extended, the rail safety latches lock into place. This
action prevents the system or expansion unit from being pulled out too far.
CAUTION:
This unit weighs approximately 43 kg (95 lb.). Ensure that you can safely
support this weight when removing the server unit from the system rack.
The IBM Systems Hardware Information Center is available for more information
or to view available video-clips that describe several of the maintenance
repair-action procedures.
Cable-management arm
The rack-mounted model is shipped with a cable-management arm to route all the
cables through the hooks along the cable arm and secure them with the straps
provided. The cable-management arm simplifies the cables management in the case
of a service action that requires you to pull out the rack-mounted system from the
rack.
Operator control panel
The service processor provides an interface to the control panel that is used to
display server status and diagnostic information. See Figure 4 on page 17 for
operator control panel physical details and buttons.
