Edge Switch 2/12 Service Manual
IML or Reset the Switch
This section describes procedures to perform an initial machine load (IML) or
reset the Edge Switch 2/12. An IML or reset is performed at the switch front panel
using the recessed IML/RESET button.
Note:
Performing an IML or switch reset does not affect the switch configuration
information.
An IML does not cause power-on diagnostics to execute and is not disruptive to
Fibre Channel traffic. The operation:
■
Reloads switch firmware from FLASH memory.
■
Resets the Ethernet LAN interface, causing the connection to the Web
browser PC to drop momentarily until the connection automatically recovers.
A switch reset is more disruptive 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 Web browser PC 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.
Caution:
A reset should be performed only if a CTP card failure is indicated.
Do not reset the switch unless directed to do so by a procedural step or the
next level of support.
Switch IML
To IML the switch from the front panel:
1. Press and hold the recessed IML/RESET button (approximately three
seconds) until the amber ERR LED blinks at twice the unit beaconing rate.
2. Release the button to IML the switch. During the IML, the switch-to-PC
Ethernet link drops momentarily until the connection automatically recovers.
