McDATA Sphereon 4400 Fabric Switch Installation and Service Manual
General Information
Power and System
Error LEDs
The PWR LED illuminates when the switch is connected to facility
AC power and is operational (the product does not have a power
switch). If the LED extinguishes, a facility power source, power cord,
or power distribution failure is indicated.
The ERR LED illuminates when the switch detects an event requiring
operator attention, such as a FRU failure. The LED illuminates as
long as an event is active. The LED extinguishes when Clear System
Error Light is selected from the EFCM Basic Edition interface or
Element Manager application. The ERR LED also blinks if unit
beaconing is enabled. An illuminated 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:
• Fibre Channel ports - LEDs above or below each port illuminate,
extinguish, or blink to indicate port status and speed. The amber
LED illuminates if the port fails. The green LED illuminates to
indicate 1.0625, 2.1250, or 4.2500 Gbps port operation.
• Power supply assembly - A green LED on each external
assembly illuminates when the FRU is operational.
Maintenance Port
The rear panel has a 9-pin DSUB maintenance port that provides a
connection for a local terminal or dial-in connection for a remote
terminal. The port is typically used only by maintenance personnel,
however operators can use the port to configure network addresses.
Chassis Ground
Connector
The front panel has a chassis ground connector for an electrostatic
discharge (ESD) wrist strap and grounding cable. Plug the grounding
cable into the connector when performing a maintenance action with
the switch connected to facility power (grounded).
