Controllers
The ACI-3144-XR chassis supports either one or two system controllers: a Primary
Controller and Secondary Controller. Considerations when replacing a controller depend
on whether a single controller or dual controllers are installed in the chassis:
• If there is only one controller installed in the chassis and you remove that
controller, the chassis loses connectivity and traffic is disrupted. When installing a
new controller, you must first set up the IP address, then either import
switch
settings and user data
or again set up aggregations.
• If there are two controllers installed in the chassis, removing one controller does
not affect traffic. The system switches to the second controller and connections
are retained. If there is a system failover that switches control to the Secondary
Controller, follow the steps for a
on page 77. The ACI-3036-XR
chassis has only one controller, so this feature is not available.
♦
To remove a controller:
1. Unscrew the thumbscrews on both sides of the controller you want to remove.
NOTE
When removing and replacing a controller, it is recommended that you first back up
switch settings and user data.
ESD CAUTION
To avoid damage to hardware from Electrostatic Discharge (ESD), do not
