Troubleshooting Optical Fibre Channel PCI Adapters
U525 and U526 Optical Fibre Channel PCI Adapters 3-9
Troubleshooting Optical Fibre Channel PCI Adapters To troubleshoot an optical Fibre Channel PCI adapter, you can perform general
troubleshooting procedures for the system and procedures specific to the optical Fibre
Channel PCI adapter.
For information about general procedures for troubleshooting your system, see the
operation and maintenance guide for your system, as listed in Tab le 1-2 , and the
Express5800/320Ma: System Administrator’s Guide. General procedures include
viewing the status of system components in ftSMC and checking for error messages in
the event logs.
To troubleshoot optical Fibre Channel PCI adapters specifically, do the following:
•Make sure that the optical Fibre Channel cable from the PCI adapter to the disk
drive is properly connected. For information about the optical Fibre Channel cable,
see “Cabling Requirements of Optical Fibre Channel PCI Adapters” on page 3-5.
If the problem persists when the cable is properly attached, replace the cable. If
replacing the cable does not fix the problem, contact NEC Technical Support or
your authorized Service Representative.
•Examine the status LED for each PCI slot and the LEDs on each optical Fibre
Channel PCI adapter.
For more information about interpreting the PCI slot LEDs, see the operation and
maintenance guide for your system, as listed in Tabl e 1-2 .
Each optical Fibre Channel PCI adapter contains two status LEDs (see Figure3-1).
For descriptions of these LEDs, see Tab le 3-3 .
