General Description

When the overheated power supply cools down, the power supply will attempt to place itself back in service. If the cause for the overheating condition is still present, the power supply will eventually overheat again and the shutdown process will repeat. During the periods where both power supplies are operating, the Power Supply Fail LED on the front of the chassis will turn OFF. The Power Supply Fail LED will only be ON when one of the two power supplies is actually failing.

Chassis Switch Panel

Refer to Figure 1-4 for the location of the Chassis Switch Panel. The Chassis Switch panel contains a microprocessor Reset button, switches for bypassing the Flash memory and Watchdog Timer, and Test Mode select switches. Use these switches only under the direction of Ancor Customer Service. Refer to the Chassis Switch Panel appendix for a description of these switches and buttons.

Switch Management Connector

The Switch Management Connector is an Ethernet 10BASE-T interface that provides a connection to a management station. The management station, running the Ancor Switch Utilities or SNMP, provides a means to access such things as the Fibre Channel Management Information Base (MIB) and upgrade the control firmware held in the Switch’s Flash memory.

Refer to the Switch Management Section of this manual for information about how to connect the management station and manage the Switch.
