RJ-45 ports for 10/100/1000BASE-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) unshielded twisted-pair (UTP) 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 the need to set up uplink
connections while eliminating concern about whether to use crossover or
straight-through cables when you attach devices.
All RJ-45 ports also support Power over Ethernet (PoE+, IEEE 802.3at). The switch can
supply up to 30W PoE+ to each port.
The maximum PoE power budget across all active PoE+ ports is 180W for model
GS716TP and 300W for model GS716TPP.
