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.
When you insert a cable into the switch's RJ-45 port, the switch automatically performs
the following actions:
• Senses whether the cable is a straight-through or crossover cable.
• Determines whether the link to the attached device requires a normal connection
(such as when you are connecting the port to a computer) or an uplink connection
(such as when you are connecting the port to a router, switch, or hub).
• Automatically configures the RJ-45 port to enable communications with the attached
device. The Auto Uplink technology compensates for setting uplink connections
while eliminating concern about whether to use crossover or straight-through cables
when you attach devices.
All RJ-45 copper ports on model GC728XP and model GC752XP support Power over
Ethernet (PoE+).
