If one desires to update all of the COM24 cards in a chassis, then all upgrade fields would be
checked as shown in
Figure 55 below.
Figure 55 – Multi-card COM24 SW Upgrade
Please note that when executing a multi-card firmware upgrade, the upgrade command will be
sent to the leftmost card slot first, and then to each of the cards in succession. As soon as each
card finishes its download, it will reset itself. If you have sent the upgrade command from a card
within the first several slots, it may be reset before all of the cards in the chassis have received
their upgrade commands, in which case the last few cards in the chassis will not be updated. In
order to avoid this situation, it is highly recommended that you execute all multi-card upgrades
while logged into the COM24 card that inhabits the rightmost slot of any given chassis.
