Fabric OS Commands bladeBeacon Set blade beaconing mode on or off. Synopsis bladeBeacon [slotnumber] mode Availability Admin Release V4.1.x Description Use this command to set the blade beaconing mode on or off. Specify mode 1 to enable beaconing mode or specify mode 0 to disable beaconing. Note: This command is only available on the StorageWorks Core switch. When beaconing mode is enabled, the port LEDs will flash amber in a running pattern from port 0 through port 15 and back again. The pattern continues until the user turns it off. This can be used to locate a physical unit. Beaconing mode only takes over the port LEDs, it does not change the switch's functional behavior. The normal flashing LED pattern (associated with an active, faulty or disabled port for example) is suppressed and only the beaconing pattern is displayed. If a diagnostic frame based test (such as portLoopbackTest, crossPortTest, or spinSilk) is executed, the two LED patterns are inter-woven. The diagnostic test flickers the LEDs green and the beaconing mode runs the LEDs amber. The switchShow command can be used to display if the status of blade beaconing mode is on or off. 68 Fabric OS Version 3.1.x/4.1.x Reference Guide
