blank covers in all power supply bays that are to remain empty (C9400-PWR-BLANK). For information about
installing blank covers, see

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 by activating
the rocker input power switch switch into the OFF state 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 rocker 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 activating the input
power into the ON state with the rocker input power switch prior to energizing the unit. Statement
