General InformationI
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 1–8) 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 upper left corner of each fan FRU (Figure 1–9) illuminates if the fan fails or rotates too slowly.
•Power Supply - A green LED on each power supply (Figure 1–9) 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 1–9) 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.
Software Diagnostic Features
The switch provides the following diagnostic software features that aid in fault isolation and repair of problems:
•FRUs provide on-board diagnostic and monitoring circuits that continuously report FRU status to the HAFM and product manager applications. These applications provide system alerts and logs that display failure and diagnostic information at the HAFM server or a remote workstation communicating with the HAFM server.
•The HAFM Services application that runs as a Windows 2000 service and provides an additional user interface to display operational status.
•The embedded web server interface that provides Internet access to isolate problems for a single switch.
•Unsolicited SNMP trap messages that indicate operational state changes or failures can be transmitted to up to 12 authorized management workstations.
