General Information
• Ethernet LAN interface, causing the connection to the
management server to drop momentarily until the connection
automatically recovers.
• Ports, causing all Fibre Channel connections to drop momentarily
until the connections automatically recover. This causes attached
devices to log out and log back in, therefore data frames lost
during switch reset must be retransmitted.
Perform a reset only if a CTP card failure is indicated. The button is
flush mounted to protect against inadvertent activation.
Ethernet LAN
Connector The front panel has a 10/100 megabit per second (Mbps) RJ-45
twisted-pair connector that attaches to an Ethernet LAN to provide
communication with a management server or simple network
management protocol (SNMP) workstation.
The connector provides two green LEDs. The left LED illuminates to
indicate LAN operation at 10 Mbps. The right LED illuminates to
indicate operation at 100 Mbps.
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. 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/blue LEDs associated with switch FRUs provide
status information as follows:
• Fibre Channel ports - LEDs to the left of each port illuminate,
extinguish, or blink to indicate port status and speed. The amber
LED illuminates if the port fails. The green/blue LED illuminates
green to indicate 1.0625 Gbps port operation. The green/blue
LED illuminates blue to indicate 2.1250 Gbps port operation.
• Power supply assembly - An amber LED on each assembly
illuminates if the FRU fails.
