Troubleshooting a Network or Fibre Channel Port Connection
If an LED on a network or Fibre Channel port indicates a problem, follow the
steps in the next sections to isolate the problem:
■ Troubleshooting a Connection to a Gigabit Ethernet Port
■ Troubleshooting a Connection to a 10/100 Ethernet Management or 10/100
Ethernet HA Port
■ Troubleshooting a Connection to a Fibre Channel Port
Troubleshooting a Connection to a Gigabit Ethernet Port
A bad connection to a Gigabit Ethernet (GE 1 or GE 2) port is indicated by the
LINK LED being off. If the LINK LED is off:
1. Verify that the cable is connected properly and is in good operating condition.
■ Disconnect and connect both ends of the cable. If the LINK LED turns on,
then the cable was not connected properly.
■ If the LINK LED remains off, replace the cable. If the LINK LED turns
on, then the cable was defective.
■ If the LINK LED remains off, the cable is most likely not the problem.
Continue to the next 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 LINK LED turns on, then the problem was
with the external end system, switch, or router.
■ If the LINK LED remains off, continue to the next step.
3. Replace the SFP module.
■ If the LINK LED turns on, the problem was the SFP module.
■ If the LINK LED remains off, contact a customer service representative
for instructions.
