Problem Recommended Action

SFP installed in one or

more ports but no

LEDs lit

1. Verify that the power cord is firmly seated into switch and is connected

to a properly earthed receptacle (outlet).

2. Check the Power LED to ensure that the switch is turned on.

3. Verify that the SFP is firmly seated.

SFP installed but only

yellow LED is lit

Reseat the SFP. If the same condition occurs, the SFP is probably faulty

and should be replaced.

SFP installed with

both green and yellow

LEDs lit

1. Make sure that the device is powered on and operating properly.

2. Unplug the fiber cable from the node and verify that an optical signal is

present on the cable receiver lead.

3. Verify that the fiber cable is fully seated at either end.

If optical power meter is available, verify the device is transmitting a

signal.

If there is no signal present, the device may require rebooting, device

drivers may need to be reinstalled, or the HBA or disk controller

hardware may require servicing.

If a signal is present on both the cable lead and the end node, the HBA

or disk controller may require service.

4. Ensure that the device and switch are operational and set to the same

speed.

SFP installed with only

green LED lit, but

devices are not

communicating

The switch is receiving a valid signal from the device, but no upper level

protocols are active.

1. Verify that the proper HBA device drivers are loaded for the

appropriate operating system and that the host has been configured to

recognize attached disk devices.

2. Improper FC-AL initialization could result from a defective or

inoperative adapter card or device. Run adapter diagnostics with a

loopback connector to see if the adapter is working properly.

3. Unplug the fiber cable from the end node and verify that an optical

signal is present on the cable receiver lead. If no signal is present, the

cable’s receiver lead may be bad and the device may be streaming F8

Failure notifications.
