Removing and Installing Port Adapters
Specifically, when you insert a module, the longest pins make contact with the module first, and the
shortest pins make contact last. The system recognizes the signals and the sequence in which it receives
them.
When you remove or insert a module, the pins send signals to notify the system of changes. The router
then performs the following procedure:

Before you begin installation, read

required for installation.
Warnings and Cautions
Observe the following warnings and cautions when installing or removing port adapters.
Do not slide a port adapter all the way into the slot until you have connected all required cables. trying
Caution
to do so disrupts normal operation of the router or switch.
Note
If a port adapter lever or other retaining mechanism does not move to the locked position, the port
adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot,
reinsert it, and move the port adapter lever or other mechanism to the locked position.
To prevent jamming the carrier between the upper and lower edges of the port adapter slot, and to ensure
Caution
that the edge connector at the rear of the port adapter mates with the connection at the rear of the port
adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway in the
following illustrations.
Caution
When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the
card. Some platforms have an ESD connector for attaching the wrist strap.
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing.
OL-3495-02
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.
