About this document
This document helps you do the following tasks:
vIdentify a failed power supply unit
vRemove the failed power supply unit and replace it with a new power supply unit
vVerify that the replacement power supply unit is working correctly
Best Practice: Replace a failed power supply unit as soon as possible.
Important: Before you proceed with these instructions, please review the IBM Systems Safety Notices
provided in the IBM Media Terms and Conditions CD that is shipped with the GX7000 Series appliance.
Identifying a failed power supply unit
There are two power supply units in the back of the GX7000 Series appliance. The power supply units
can be hot-swapped, so you can replace a single power supply unit without powering down the GX7000
Series appliance.
Understanding the power supply unit LED status
Each power supply unit contains an LED that indicates whether the unit is working as expected,
generally:
vAn LED that is lit green (solid or blinking) indicates that the unit is working as expected.
vAn LED that is lit amber or is not lit (off) indicates that the unit is not working as expected.
Understanding the fault LED status
There are also fault LEDs on the front panel of the appliance that illuminate in amber when there is a
problem with one of the power supply units:
v: The fault LED for the power supply unit that is located in the top slot of the chassis in the back
of the appliance.
v: The fault LED for the power supply unit that is located in the bottom slot of the chassis in the
back of the appliance.
Note: The fault LEDs on the front panel might vary in appearance depending on which GX7000 Series
appliance you are using.
