This section covers the implementation details for the Firmware Download 
Management Information Bases (FD-MIB) on the SANbox switch. 

The FD-MIB enables you to download, install, and activate new firmware on 
QLogic SANbox 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 hotreset 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/hotreset 
to multiple switches, only perform the NDCLA/hotreset on one switch at a time, 
and wait 75 seconds before performing the NDCLA/hotreset 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.
