The Port Replicator incorporates NIC pass though so the network card of the notebook provides the networking capabilities. The system main battery can be charged when connected to the Port Replicator if the AC Adapter provided with the Port Replicator is plugged in. The Port Replicator has a security slot that incorporates two levels of security. One slot allows the Port Replicator to be secured to a stationary object. The second slot locks the Port Replicator and the notebook to a stationary object. This security feature works only in conjunction with an optional security cable lock accessory kit.
