A-Class Server Trouble Shooting
Electrostatic Discharge Precautions. The procedures in this section require
opening the server and exposing the system to electrostatic discharge. Always
observe all electrostatic precautions when working with components inside or out of
the server. Failure to follow these precautions may result in component damage or
loss of system reliability.
•
Use a grounding mat and an anti-static wrist strap.
•
Wear the anti-static wrist strap to ensure that any accumulated electrostatic
charge is discharged from your body to ground.
Before You Do Anything...
o
Power down the system.
o
Unplug the server.
NOTE
Cabinet-mounted servers must be removed from the cabinet before proceeding.
o
Remove the top of the server by unscrewing the knurled captive screws on each
side of the rear of the server. Slide the top back, lift it off, and set it aside.
Step 1. Document the I/O configuration (write down which type of I/O board is installed in
which of the I/O slots).
Step 2. Remove all I/O boards. Power up the server and observe the front panel LEDs.
Step 3. If the fault does not recur and only a single I/O board was removed, that I/O card is
the cause of the I/O Subsystem or I/O Board Fault. Replace that I/O board, power on
the server, and observe the front panel LEDs. If the problem recurs, proceed to step
8.
Step 4. If the fault does not recur and two I/O boards were removed, install the bottom I/O
card, power up the server, and observe the front panel LEDs.
Step 5. If the fault recurs, the I/O card in the bottom slot is the cause of the I/O Subsystem
or I/O Board Fault. Replace that I/O board.
Step 6. If the fault does not recur, install the second I/O card, power up the server, and
observe the front panel LEDs.
Step 7. If the problem recurs, replace the top I/O card.
Step 8. If replacing the I/O card does not clear the I/O Subsystem or I/O Board Fault, the
problem is with the system board. To change the system board, you must replace the
