• Ports, causing all Fibre Channel connections to drop momentarily until the connections

automatically recover.

An IML should only be performed if a CTP failure is indicated. Do not IML the switch unless directed

to do so by a procedural step in this manual or by the next level of support. As a precaution, the IML

button is flush mounted to protect against accidental activation.

Ethernet LAN connector

The front panel provides a 10/100 megabit per second (Mbps) RJ-45 twisted-pair connector

(Figure 1 on page 17) that attaches to an Ethernet LAN to provide communication with the on

page 17 or an SNMP management workstation. Two green LEDs are associated with the LAN

connector. When illuminated, the left LED indicates LAN operation at 10 Mbps, and the right LED

indicates LAN operation at 100 Mbps.

Power and system error LEDs

The PWR LED (Figure 1on page 17) 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 on page 17) 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. 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 on page 17) 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 on page 17) illuminates if the

fan fails or rotates too slowly.

• Power Supply—A green LED at the upper left corner of each power supply (Figure 2 on

page 17) 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 2 on page 17) 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.
