Figure 3–4 Replacing an SBB
3.6.3 Replacing a Power Supply
You can replace a power supply without affecting pedestal operation using the
following procedure:
CAUTION
When you remove a power supply, the airflow
through the SBBs is interrupted. Always install the
replacement power supply as quickly as possible
to prevent overheating.
1. Grasp the power supply handle shown in Figure 3–5.
2. Slide and hold the locking latch to the left and pull the supply out using a
short jerking motion.
3. Insert the replacement power supply into the pedestal and carefully align it.
4. Push the power supply in until it is fully seated and the locking tab engages.
5. Until the fan is operating at the proper speed, the green power supply LED
remains off. When the fan reaches the proper speed (several seconds), the
LED should come on.
