Important Guidelines for I/O Bracket Assembly (Expansion
Board Assembly) Replacement
To replace the I/O bracket assembly, you MUST follow these steps:
1. Grasp the assembly and insert it into the chassis and connector on the system board. Press
firmly on the I/O bracket assembly, where the backplane is connected to the system
board.
2. After connecting the power cord to the grounded AC outlet and to the workstation, DO
NOT turn on the power switch if the power LED is a steady amber color. A steady amber
color indicates that the I/O bracket assembly, processor(s), or terminator board (if
installed) is not seated properly.
Disconnect the power cord from the grounded AC outlet, reseat the I/O bracket assembly,
processor(s), or terminator board (if installed), then reconnect the power cord. Once these
components are seated properly and the power LED is a steady green color, disconnect
the power cord once again before continuing with additional service.
WARNING: DO NOT turn on the power switch unless the I/O bracket assembly,
processor(s), and terminator board (if installed) are seated properly and the power
LED is a steady green color. To reduce the risk of injury, DO NOT turn on the
power switch until the workstation is completely reassembled.
