Amber Fault Leds (Rackmount) - IBM F10 Service Manual

v No. The operating temperature is normal. Answer the next question.
Are other amber LEDs lit on the drive module?
v Yes. Go to the appropriate procedure to replace the failed hardware
component. Refer to "Drive Module Troubleshooting Chart" on page 198 for
guidance.
v No. Go to Step 4.

4. Answer the following questions.
Has the operating system or Storage Manager software issued an error
relating to the ESM board or I/O transmission to the disk array?
v Yes. Go to Step 6.
v No. Answer the next question.
Can you perform I/O operations to the drives successfully?
v Yes. Return to normal operation.
v No. Read "Hints for Troubleshooting Interface Problems" on page 169 and
try to determine the source of the interface problem. If you still cannot
determine the source of the problem, go to Step 6 and replace the ESM
FRU.
5. Check the fans and ventilation in the cabinet.
Check the LEDs on both fan FRUs. If one or both amber LEDs are lit on the
fan FRUs, go to "Replace a Failed Fan" on page 188 to replace the failed fan
FRU. If the amber LEDs are off, then check the ambient temperature inside
the cabinet to make sure it is within the required operating range (5° C to 40°
C [41°F to 104°F]). If it is too hot, shut down the drive module and take
necessary steps to cool the environment. If the fans are working and the
temperature is within the normal operating range, go to Step 6.
6. Shut down the drive module (Figure 87 on page 172).
If applicable, stop all I/O activity to the drive module and logically disconnect
the drives from the host. Turn off both power switches and unplug both power
cords from the back of the drive module. All LEDs should be off.
7. Disconnect the interface cables (Figure 87 on page 172).
