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 ) that attaches to an Ethernet LAN to provide communication
with the HAFM server 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 1 ) 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 ) 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
Product 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 )
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 2 )
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 ) 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 ) 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.
