Switch Hardware Interfaces
The following sections describe the hardware interfaces on the switch.
RJ-45 Ports for 10/100/1000M BASE-T Ethernet Connectivity
All RJ-45 copper ports support autosensing. When you insert a cable into an RJ-45 port, the switch
automatically ascertains the maximum speed (10 Mbps, 100 Mbps, or 1 Gbps) and duplex mode (half-duplex
or full-duplex) of the attached device. All ports support a Category 5e (Cat 5e) cable (or higher-rated Ethernet
cable) terminated with an 8-pin RJ-45 connector.
To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink technology.This
technology allows attaching devices to the RJ-45 ports with either straight-through or crossover cables.
