Power off switch
To power off the switch:
1. Notify the customer the switch is to be powered off. Ensure the
system administrator quiesces Fibre Channel frame traffic
through the switch and sets attached devices offline.
2. Set the switch offline. Refer to Set online state (EFCM Basic
Edition) or Set online state (SAN management application) for
instructions.
DANGER
Multiple power cords
(L003)
3. Disconnect power cords from the AC connectors at the rear of the
switch.
IML or reset switch
ATTENTION! A reset should only be performed if a CTP card failure is
indicated. Do not reset a switch unless directed to do so by a procedural step
or the next level of support.
An initial machine load (IML) or reset is performed at the switch front
panel using the
RESET button. An IML does not cause power-on
diagnostics to execute and is not disruptive to Fibre Channel traffic.
An IML:
• Reloads switch firmware from FLASH memory.
• Resets the Ethernet LAN interface, causing the connection to the
browser PC or management server to drop momentarily until the
connection automatically recovers.
A reset is disruptive to Fibre Channel traffic and resets the:
• Microprocessor and functional logic for the control processor
(CTP) card and reloads the firmware from FLASH memory.
