Switch hardware interfaces
The following sections describe the hardware interfaces on the switch.
RJ-45 ports for 100/1000M and 2.5G/5G/10G 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. Depending on the port, the
switch can autodetect 100 Mbps or 1 Gbps and duplex mode (half-duplex or full-duplex),
or 2.5 Gbps, 5 Gbps, or 10 Gbps of the attached device. All ports support Ethernet
cables that are terminated with 8-pin RJ-45 connectors.
Use Category 5e (Cat 5e) Ethernet cables terminated with RJ-45 connectors to make
1G, 2.5G, and 5G connections. For 10G connections, use Cat 6a or higher-rated Ethernet
cables terminated with RJ-45 connectors.

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.
For model MS510TXUP, all copper ports (1 through 8) also support PoE++ (up to 60W
per port).
