Introduction

28 Edge Switch 2/32 Installation Guide

Ethernet LAN Connector

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

connector (Figure 1 on page 25) that attaches to an Ethernet LAN to provide

communication with the on page 25 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 25) 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 25) 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 25) 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 25) 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 26) 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 26)

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.
