General Information

Power and System

Error LEDs The PWR LED (Figure 1-6 on page 1-19) illuminates when the switch
is connected to facility AC power and powered on. If the LED
extinguishes, a facility power source, power cord, or power
distribution failure is indicated.
The ERR LED (Figure 1-6 on page 1-19) illuminates when the switch
detects an event requiring immediate operator attention, such as a
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.
FRU Status LEDs 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
(Figure 1-6 on page 1-19) 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
(Figure 1-7 on page 1-19) illuminates if the fan fails or rotates too
slowly.
Power Supply - A green LED at the upper left corner of each
power supply (Figure 1-7 on page 1-19) illuminates if the power
supply is operational and receiving AC power.
Maintenance Port The rear panel provides a 9-pin RS-232 maintenance port (Figure 1-7
on page 1-19) that provides a connection for a local terminal or dial-in
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.
