Switch hardware interfaces

The following sections describe the hardware interfaces on the switch.
RJ-45 ports for 100/1000M and 2.5G BASE-T Ethernet
connectivity
All RJ-45 copper ports support autosensing. When you insert a cable into an RJ-45 port
and link two Ethernet devices, the switch automatically detects the maximum speed
and duplex mode (half-duplex or full-duplex)
So when you install a new cable with RJ-45 connectors, the ports at either end
auto-negotiate to determine if they will communicate at 1Gbps or 2.5Gps per minute.
The ports also interact to decide if they will support half-duplex (only one side transmits
at a time) or full-duplex (both sides transmit at the same time). This applies to all 24
ports supporting Ethernet cables terminated with 8-pin RJ-45 connectors.
Use Category 5e (Cat 5e) Ethernet cables terminated with RJ-45 connectors to make
1G, or 2.5G, connections.
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.
