General InformationI

•RS-232 maintenance port.

Initial Machine Load Button

When the IML button (Figure 1–8) is pressed and held for three seconds, the switch performs an IML that takes approximately 30 seconds and resets the:

•Microprocessor and functional logic for the CTP card and loads firmware from FLASH memory.

•Ethernet LAN interface, causing the connection to the HAFM server to drop momentarily until the connection automatically recovers.

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

An IML should only be performed if a CTP card failure is indicated. Do not IML the switch unless directed to do so by a procedural step or 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 1–8) 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 1–8) 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 1–8) 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.
