Installing Power Supply Modules
Power supply modules install directly onto the NIU module, Expansion Receiver
Modules, and supplementary power supply carriers. The power supply provides
+5V and +3.3V to downstream modules through the mating connector. The number
of modules that can be supported depends on the power requirements of the
modules. Additional booster power supplies can be used as needed to meet the
power needs of all modules. The configuration software provides power
calculations with a valid hardware configuration. If a rack includes more than one
power supply, additional power supplies must be installed so that they can be turned
at the same time as the main power supply.
1. The latch on the power supply must be
in the unlocked position.
2. Align the connectors and the latch post
and press the power supply module
down firmly, until the two tabs on the
bottom of the power supply click into
place. Be sure the tabs are fully inserted
in the holes in bottom edge of the NIU,
ERM, or carrier.
3. Turn the latch to the locked position to
secure the power supply.
Removing the Power Supply
Exercise care when working around operating equipment. Devices may become
very hot and could cause injury.
1. Remove power.
2. Turn the latch to the unlocked position
as illustrated.
3. Press the flexible panel on the lower
edge of the power supply to disengage
the tabs on the power supply from the
holes in the carrier.
4. Pull the power supply straight off.
