PSU
The procedure for hot-swapping an AC PSU, in this section, is applicable for a system that is currently
running.
1.
Remove the faulty PSU.
-
Unscrew the thumbscrew and set it aside.
-
Set the latch into open position, and gently guide the AC PSU out and away from the slot.
2.
Insert the replacement PSU.
-
Guide the AC PSU into the empty slot, and adjust the latch so that the latch tab can clear the
slot cutout, then push the AC PSU in until it stops.
-
Guide the latch into upright position. It should be completely flush with the surface of the front
panel when fully closed.
3.
Insert the thumbscrew and twist to finger-tight.
4.
Check the LEDs at the front panel of the AC PSUs (
). The Green LED should now be
illuminated.
