Chapter 3: AT-SBx81CFC960 Controller Fabric Card
76 Section I: Hardware Overview
Reset Button
You may use the Reset button to reset either the controller card or all of
the cards in the chassis. The action depends on the number of AT-
SBx81CFC960 Controller Cards in the chassis and, if the chassis has two
controller cards, whether you reset the active or standby master controller
card.
The possible actions are described here:
 If the chassis has only one controller card, pressing the Reset
button resets the controller card and all of the Ethernet line cards in
the chassis. You may perform this function if the chassis and line
cards are experiencing a problem.
Caution
The controller and Ethernet line cards do not forward network traffic
for about three minutes while they initialize the AlliedWare Plus
Operating System and configure their parameter settings. Some
network traffic may be lost.
 If the chassis has two controller cards, pressing the Reset button
on the active master controller card resets the controller card, but
not the Ethernet line cards. The standby master controller card
immediately becomes the new active master card and the Ethernet
line cards continue to forward traffic. The reset controller card is
unavailable for about two minutes while it initializes its AlliedWare
Plus Operating System, after which it becomes the standby master
controller card in the chassis.
Note
The available bandwidth of the backplane in the chassis is reduced
for about one minute while the reset controller card initializes its
management software. This may reduce network performance.
 If the chassis has two controller cards, pressing the Reset button
on the standby master controller card resets that card, but not the
active master controller card or the Ethernet line cards.
Note
The available bandwidth of the backplane in the chassis is reduced
for about one minute while the standby master controller card
initializes its management software and synchronizes its database
with the active master controller card. This may reduce network
performance.
