FRU failure. The LED remains illuminated as long as an event is
active. The LED extinguishes when the Clear System Error Light
function is selected from the Element Manager application. The LED
blinks if unit beaconing is enabled. An illuminated ERR LED
(indicating a failure) takes precedence over unit beaconing.
Amber and green LEDs associated with switch FRUs provide status
information as follows:
•
Port SFP - Amber and green LEDs to the left of the port
on page 19) illuminate, extinguish, or blink to indicate various
port states (operational with active Fibre Channel traffic,
operational but not communicating, beaconing, blocked, failed,
inactive, or running diagnostics).
•
Fan - An amber LED at the lower left corner of each fan

The rear panel provides a 9-pin RS-232 maintenance port

connection for a remote terminal. Although the port is typically used
by authorized maintenance personnel, operations personnel can use
the port to configure switch network addresses.
The switch provides the following diagnostic software features that
aid in fault isolation and repair of problems:
•
FRUs provide on-board diagnostic and monitoring circuits that
continuously report FRU status to the SAN Management and
element Manager applications. These applications provide
system alerts and logs that display failure and diagnostic
information at the management server or a remote workstation
communicating with the management server.
