Troubleshooting a Network or Fibre Channel Port Connection

•If the LINK LED turns on, the problem was the SFP module.

Troubleshooting a Connection to a 10/100 Ethernet Management or 10/100 Ethernet HA Port
A bad connection to the 10/100 Ethernet Management or the 10/100 Ethernet HA port (MGMT 10/100 or HA 10/100) is indicated by the ACT LED not being on. If the ACT LED is not on, follow these steps to help isolate the problem:
Step 1 Check to make sure that the cable is connected properly and in good operating condition.
•Verify that the cable is the correct type of cable. (See Appendix B, “Cable and Port Pinouts”.)
•Disconnect and connect both ends of the cable. If the ACT LED turns on, then the cable was not connected properly.
•If the ACT LED remains off, replace the cable. If the ACT LED turns on, then the cable was defective.
•If the ACT LED remains off, the cable is most likely not the problem. Continue to the next step.
Step 2 Check the external end system, switch, or router to which the port is connected.
•If the external end system, switch, or router is operating properly, continue to the next step.
•If the external end system, switch, or router is not operating properly, then correct the problem. If the ACT LED turns on, then the problem was with the external end system, switch, or router.
•If the ACT LED remains off, contact a customer service representative for instructions.
