6-5 Power Supply
The NovaScale R422/R422-INF server has a single 980 watt power supply. This power
supply has the capability of operating at 100 - 240 input volts. Depress both main power
buttons on the front of the chassis and then unplug the AC power cord to completely
remove power from the system before removing the power supply.
Power Supply Failure
If the power supply unit fails, the system will shut down and you will need to replace the
power supply unit. Replacement units can be ordered directly from Bull S.A.S. Support
(PWS-981-1S - see contact information in Chapter 1 ).
Replacing the Power Supply
1. Accessing the inside of the system
To replace a power supply, you must fi rst remove the top chassis cover. To do so, fi rst
release the retention screws that secure the unit to the rack. Grasp the two handles on
either side and pull the unit straight out until it locks (you will hear a "click"). The top cover
of the chassis is secured with four screws: two at the top rear of the cover and one on each
side lip, also near the back. Remove all four, then place both thumbs in the indentations
and push the cover back until it slides off. You can then lift the top cover from the chassis to
gain full access to the inside of the server.
2. Removing the power supply
First unplug the power cord from the system. To remove the failed power unit, remove the
two screws on the back of the power supply, which secure it to the chassis. You can then lift
the unit straight out of the chassis. (See Figure 6-5.)
3. Installing a new power supply
Replace the failed unit with another unit of the same wattage. You must replace it with the
exact same power supply. Carefully insert the new unit into position in the chassis and
secure it with the two screws at the rear of the unit. Before reconnecting the power cord,
make sure the power switch on the power supply is in the off position. Then reconnect the
power cord, replace the chassis top cover and push the unit back into the rack. Finish by
turning the power switch on the power supply on, and then depress the power buttons on
the front of the chassis.
