Not all features listed in this guide are available on all workstations.
5.1 Preparation
for
Disassembly
See Chapter
4
, 'Identifying the Chassis, Routine Care, and Disassembly Preparation' for initial
procedures.
1. Remove/disengage any security devices that prohibit opening the workstation (Section
5.2
and
5.4
).
2. Close any open software applications.
3. Exit the operating system.
4. Remove any media such as a diskette or compact disc from the workstation.
5. Turn off the workstation and any peripheral devices that are connected to it.
Ä
CAUTION:
Turn off the workstation before disconnecting any cables.
Ä
CAUTION:
Regardless of the power-on state, voltage is always present on the system board as long as
the system is plugged into an active AC outlet. In some systems the cooling fan is on even when the
workstation is in the “Standby,” or “Suspend” modes. The power cord should always be disconnected
before servicing a unit.
6. Disconnect the power cord from the electrical outlet and then from the workstation.
7. Disconnect all peripheral device cables from the workstation.
✎
During disassembly, label each cable as you remove it, noting its position and routing. Keep all
screws with the units removed.
Ä
CAUTION:
The screws used in the workstation are of different thread sizes and lengths; using the wrong
screw in an application may damage the unit.
