WARNING:
Do not attach any cables or power cords to the power supply until it is
installed in the carrier.
Do not power up the control unit until all of the modules and power
equipment are installed. Once they are installed, refer to
the System'', later in this chapter. Failure to comply with this procedure
can result in shock hazard and/or damage to the equipment.
If you are upgrading an older system and a ring generator is specified in
the system forms (Control Unit Diagram), install it in the power supply
before putting the power supply in the carrier. The procedure is detailed in
Maintenance and Troubleshooting.
For expansion carriers with older power supply modules only, a copper
shield must be installed on the power supply before installing it in the
carrier. The procedure is explained in
this chapter.
Before touching leads, connectors, pins, and other components, use a
properly grounded wrist strap, to prevent damage from electrostatic
discharge (ESD).
Remove the protective cover from the gold-finger connector (on the back
of the power supply) before inserting it into the carrier.
