Common hardware interfaces
This section describes the hardware interfaces that are common to the M4350 series
switch models.
Gigabit and Multispeed Gigabit RJ-45 copper ports
All 1 Gbps and multispeed Gigabit RJ-45 copper ports support autosensing. When you
insert a cable into an RJ-45 port, the switch automatically detects the attached device’s
maximum speed: 100 Mbps, 1 Gbps, and, depending on the model, 2.5 Gbps, 5 Gbps,
or 10 Gbps. For devices that support 100 Mbps, the switch automatically detects the
duplex mode (half-duplex or full-duplex).
We recommend using the following cables:
•
Category 5e (Cat 5e) or higher-rated cable for a copper port at 1 Gbps or 2.5 Gbps.
•
Category 6a (Cat 6a) or higher-rated cable for a copper port at 10 Gbps.
For more information about Ethernet cables, see Speed and cables on page 46.
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.
