Service Preparations

Before beginning any of the removal and replacement procedures, complete the
following steps:
1. Turn off the workstation.
2. Disconnect the power cord from the grounded AC outlet and then from the workstation.
3. Turn off all peripheral devices and disconnect cables from the rear of the workstation.
4. Remove the cable lock in order to access internal components. Refer to the following
section for instructions on how to remove the cable lock.
NOTE: In some of the removal procedures in this chapter, you will be asked to remove the
workstation feet and lay the workstation on its side when servicing some of the internal
components.
NOTE: For more information on preparing the workstation for service, see Chapter 2.
CAUTION: The power supply in the Compaq Professional Workstation SP700 has
an auxiliary power section. This section is always active as long as the unit is
plugged into a live AC outlet. Be sure to turn off the switch and unplug the power
cord before performing any service work.
CAUTION: Electrostatic discharge can damage electronic components of the
workstation. Before beginning these procedures, be sure you are properly
grounded. See "Electrostatic Discharge Information" in Chapter 2 for more
information.
