Firmware Download MIB 
Objects
This section covers the implementation details for the Firmware Download 
Management Information Bases (FD-MIB) on the QLogic switch. 
Firmware Download MIB Definitions
The FD-MIB enables you to download, install, and activate new firmware on 
QLogic switches using the Trivial File Transfer Protocol (TFTP). The downloaded 
firmware can be activated using a hot reset (non-disruptive) or a hard reset 
(disruptive).
A hot reset is a Non-Disruptive Code Load Activation (NDCLA) operation. The 
firmware will be activated, the switch will be reset without a Power On Self Test, 
and switch traffic will not be disrupted. The switch does not need to be rebooted 
after the firmware is activated. During a hot reset operation, fabric services will be 
unavailable for a short period (30-75 seconds depending on switch model). To 
ensure that the NDCLA operation is successful, verify that all administrative 
changes to the fabric (if any) are complete. When you need to do NDCLA/hot 
reset to multiple switches, only perform the NDCLA/hot reset on one switch at a 
time, and wait 75 seconds before performing the NDCLA/hot reset operation on 
the next switch.
A hard reset is a Normal (or regular) reset operation. The firmware will be 
activated, the switch will be reset with a Power On Self Test, and switch traffic will 
be disrupted. The switch must be rebooted after the firmware is activated.
