SAN32M1 Fabric Switch Installation and Service Manual 348
• Perform partial power-on diagnostics, reset functional logic for
the CTP card, and load firmware from FLASH memory to
random-access memory (RAM) without powering off the switch.
• Reset the Ethernet local area network (LAN) interface, causing
the connection to the EFC Server to drop momentarily until the
connection automatically recovers.
• Automatically enable changes to an active zone configuration.
• Keep all configured fabric logins, name server registrations, and
operating parameters intact.
• Automatically set the switch online. The blocked state of each
Fibre Channel port remains intact.
NOTE: A switch reset or IPL should be performed only if a CTP card failure
is indicated. Do not reset or IPL the switch unless directed to do so by a
procedural step or the next level of support.
Reset the switch
Resetting the switch with the IML button causes the switch to
perform an initial machine load (IML) that takes approximately 30
seconds.
To reset the switch:
1. At the switch front panel, press and hold the IML button for
approximately three seconds.
2. During the reset, the switch-to-EFC Server Ethernet link drops
momentarily and the following occurs at the Element Manager
application:
— As the network connection drops, the Status table turns
yellow, the Status field displays No Link, and the State field
displays a reason message.
— The alert panel at the bottom of the navigation control panel
displays a grey square, indicating switch status is unknown.
— Illustrated FRUs (SFPs, fans, and power supplies) in the
Hardware View disappear, and appear again as the connection
is re-established.
