Chapter 1: General information
Controls, connectors, and indicators
Controls, connectors, and indicators for the switch include the:
•
RESET
button.
•
Ethernet LAN connector.
•
Green
PWR
and amber
ERR
LEDs.
•
Green and amber status LEDs associated with CRUs.
•
RS-232 maintenance port.
•
Chassis ground (
GND
) connector.
RESET button
When the
RESET
button is pressed, held for three seconds, and
released, the switch performs an initial machine load (IML) that
reloads the firmware from FLASH memory. This operation is not
disruptive to Fibre Channel traffic. When the
RESET
button is
pressed and held for ten seconds, the switch performs a reset. After
three seconds, the
ERR
LED blinks at twice the unit beaconing rate. A
reset is disruptive to Fibre Channel traffic and resets the:
•
Microprocessor and functional logic for the CTP card and reloads
the firmware from FLASH memory.
•
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.
