In the course of its operation the system may require more than one power supply installed and
supplying power. Should it become necessary to remove an active power supply unit from the
system, consult the user manual for proper system administration of available power. In order to
safely de-energize the power supply unit, the input power should first be turned off and the power
cable physically disconnected from the unit. The unit must then be removed from the slot and stowed
safely away in a proper antistatic bag. Care must be taken not to touch any of the exposed pins from
the backplane connector. When a replacement power supply unit is to be installed, its power switch
must always be in the OFF state and no input power cable be installed prior to inserting it into the
slot. After the unit is seated, the input power cable may then be installed and fastened securely
before switching on the power supply.
