RJ-45 Ports for 10/100/1000M BASE-T 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 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 copper ports also support Power over Ethernet (PoE+). In addition, the two small form-factor pluggable
(SFP) ports can support 1G fiber optical modules.
