Hot-Swapping A Power Supply - NEC EXPRESS5800/120Lf User Manual

Hot-Swapping a Power Supply

Your system power is hot swappable only if your system is equipped with two
power supplies. If a supply malfunctions it is hot swappable.
When you are swapping out a faulty power supply, you can determine which
one to remove by checking the status LED panel indicator on each supply. If the
LED panel indicator on a power supply is lit amber (failure) the power supply
can be hot-swapped.
If your system is equipped with only one power supply, it is not hot swappable
and it is recommended that power to the system be turned off before removing
the power supply.
To hot-swap a power supply, perform the following steps:
1. At the rear of the cabinet locate the defective power supply. If the LED
panel indicator on a power supply is lit amber the power supply is defective.
2. Remove the power supply by grasping its handle (1) with your right hand,
press the latch with your index finger, pull the handle down slightly (2), and
slide the power supply out of the bay (3). See Figure 4-59.
3. Slide the new power supply into the bay until its latch clicks into place. See
Figure 4-60.
