108 Fabric OS Command Reference

53-1001764-01

chassisBeacon

Sets chassis beaconing mode.

SYNOPSIS chassisbeacon [mode]

DESCRIPTION Use this command to enable or disable beaconing on a chassis. Chassis beaconing can be used to

locate a failing chassis in a group of chassis. Use the portBeacon command to locate a failing port, and

use the switchBeacon command to locate a failing (logical) switch.

When beaconing mode is turned on, the port LEDs flash green at various rates across the chassis. The

beaconing continues until you turn it off.

Beaconing mode takes over the port LEDs. The normal flashing LED pattern associated with an active,

faulty, or disabled port is suppressed, and only the beaconing pattern is shown. Other commands are still

executable and functional. However, if diagnostic frame-based tests such as portLoopbackTest are

executed, the diagnostic LED pattern is interleaved with the beaconing pattern.

NOTES The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in

place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for

details.
