Switch Hardware Interfaces

The following sections describe the hardware interfaces on the switch.

1G/10G RJ-45 Ports

All copper RJ-45 ports support AutoSensing. When you insert a cable into an RJ-45 port, the
switch automatically ascertains the maximum speed (1 Gbps or 10 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 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. This
technology allows attaching devices to the RJ-45 ports with either straight-through or
crossover cables.
Note: For 10GBASE-T ports, Ethernet specifications limit a Category 6
(Cat 6) cable length between the switch and the attached device to
328 feet (100 meters).
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.
Designation
Green LED (10G LED)
• Off . No SFP+ module is inserted or no module link is established.
• Solid green . A valid 10 Gbps link is established.
• Blinking green. The module is transmitting or receiving packets at 10 Gbps.
Yellow LED (1G LED)
• Off . No SFP+ module is inserted or no module link is established.
• Solid yellow . A valid 1 Gbps link is established.
• Blinking yellow. The module is transmitting or receiving packets at 1 Gbps.
