Replacement
To replace the I/O bracket assembly (expansion board bracket), you MUST follow these steps:
1.
Grasp the assembly and insert it into the chassis and connector on the system board with
tray. Press firmly on the I/O bracket assembly, where the backplane is connected to the
system board with tray.
2.
Plug in the power cord, but DO NOT turn on the power switch.
3.
The auxiliary power section of the power supply should now be active. If the I/O bracket
assembly is not seated properly when the auxiliary power is active, the power LED will
be lit amber. Unplug the system and reseat the assembly. Once the assembly is seated
properly, unplug the workstation before continuing with additional service.
WARNING:
DO NOT turn on the power switch unless the I/O bracket assembly is
seated properly. For safety, DO NOT turn on the power switch until the workstation
is completely reassembled.
