Removing and Installing Port Adapters
Specifically, when you insert a module, the longest pins make contact with the module first, and the

Warnings and Cautions
Observe the following warnings and cautions when installing or removing port adapters.
Caution
Do not slide a port adapter all the way into the slot until you have connected all required cables. Trying
to do so disrupts normal operation of the router or switch.
To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and to

Rapidly scans the system for configuration changes.
Initializes newly inserted port adapters or administratively shuts down any vacant interfaces.
Brings all previously configured interfaces on the module back to their previously installed state.
Any newly inserted interface is put in the administratively shutdown state, as if it was present (but
not configured) at boot time. If a similar module type is reinserted into a slot, its ports are configured
and brought online up to the port count of the originally installed module of that type.
