Installing the RA4100
Before beginning these procedures, make sure you understand the following
warnings and caution:
WARNING: To reduce the risk of personal injury or damage to the equipment,
be sure that:
■ The leveling jacks are extended to the floor.
■ The full weight of the rack rests on the leveling jacks.
■ The stabilizing feet are attached to the rack, if it is a single rack
installation.
■ The racks are coupled in multiple rack installations.
■ A rack may become unstable if more than one component is extended for
any reason. Extend only one component at a time.
WARNING: To reduce the risk of electric shock or damage to the equipment:
■ Do not disable the power cord grounding plug. The grounding plug is an
important safety feature.
■ Plug the power cord into a grounded (earthed) electrical outlet that is
easily accessible at all times.
■ Install the power supply before connecting the power cord to the power
supply.
■ Unplug the power cord before removing the power supply.
■ If the system has multiple power supplies, disconnect power from the
system by unplugging all power cords from the power supplies.
CAUTION: The Compaq RA4100 must always be operated with the system unit
cover on. Proper cooling will not be achieved if the system unit cover is
removed.
