LEDoperation other than expected or LEDs may indicate link problems. For example, all LEDs flashingamber for a port indicates that an invalid non-Brocade SFP may be installed. For details on adapterLED operation, refer to the “LED Operation” section for your adapter in the Brocade AdaptersInstallation and Reference Manual. If LEDs do not illuminate to indicate an active link, useappropriate Fabric OS and adapter diagnostic commands and HCM options in Table 3 on page 51.For additional diagnostics commands, refer to Chapter 3, “Tools for Collecting Data” for HCM andBCU commands and the Fabric OS Administrator’s Guide for Fabric OS commands.NOTEAlso verify LED operation on a switch port that is connected to an adapter port. Refer to the switchhardware reference manual to analyze LED meaning.
