202 Director 2/64 Service Manual

IML, IPL, or Reset the Director

This section describes procedures to IML, IPL, or reset the Director 2/64. An IML

or reset is performed at the CTP front panel using the IML or the RESET button.

An IPL is performed from the HAFM appliance (Director 2/64 Element

Manager). Do not IPL the director unless directed to do so by a procedural step or

the next level of support. An IML and IPL are functionally equivalent. The

operations do not cause power-on diagnostics to execute and are not disruptive to

Fibre Channel traffic. Both operations:

■ Reset the functional logic for the active CTP2 card only. An IPL does not reset

the backup CTP2 card, SBAR cards, or UPM cards. All director switching

operations continue unaffected.

Note: An initial machine load (IML) performs essentially the same functions, but resets

both CTP2 cards. A director IML is initiated by pressing and holding the white IML

button (on the faceplate of either CTP2 card) for three seconds.

■ Load firmware from the CTP2 card FLASH memory without cycling director

power.

■ Reset the Ethernet local area network (LAN) interface on the active CTP2

card, causing the connection to the HAFM appliance to drop momentarily

until the connection automatically recovers.

■ Automatically enable changes to an active zone configuration.

■ Keep all fabric logins, name server registrations, and operating parameters

intact.

■ Automatically set the director online. The blocked or unblocked state of each

port remains intact.
