Switch hardware interfaces
This section describes the hardware interfaces that are common to the M4250 series
switch models.
1GBASE-T RJ-45 and 2.5GBASE-T RJ-45 copper ports
All 1GBASE-T RJ-45 and 2.5GBASE-T RJ-45 copper ports support autosensing. When
you insert a cable into an RJ-45 port, the switch automatically detects the maximum
speed (10 Mbps, 100 Mbps, 1 Gbps, or 2.5 Gbps) of the attached device. For devices
that support 10 Mbps or 100 Mbps, the switch automatically detects the duplex mode
(half-duplex or full-duplex). All ports support a Category 5 (Cat 5) unshielded twisted-pair
(UTP) cable or higher-rated Ethernet cable terminated with an 8-pin RJ-45 connector.
For more information about Ethernet cables, see Cables and speed on page 26.
Note: Use a Category 5e (Cat 5e) or higher-rated cable for a copper port at 1 Gbps.
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.
PoE port capacities and budgets
The Power over Ethernet (PoE) models support eight PoE+ or PoE++ ports with the port
capacities and budgets that are described in the following table.
