Upgrading Your System 4-11
Removing a Power Supply
CAUTIONs
Turn off peripheral devices:
If the chassis contains only
two power supplies, turn off all peripheral devices connected
to the server. Then turn off the server power with the push-
button on/off switch on the front panel.
Populate all bays:
Figure 4-4 shows the far-right power
supply bay vacant. To ensure correct airflow, you must
populate this bay with a redundant power supply or cover
panel. The figure is intended to show a power supply bay
with the supply removed and not yet replaced, not an
acceptable configuration for a system during operation.
1.
Look at the yellow FAIL LEDs on the power supplies to determine which
one is defective.
2.
Pull the power supply handle down to unlock it from the chassis.
3.
Pull the power supply straight back, out of the chassis. Set it aside.
