Cabling Copper Ports
Here are the guidelines to cabling the 10/100/1000Base-T copper ports:
The cable specifications for the ports are listed in “Cable
The connectors on the cables should fit snugly into the ports, and
the tabs should lock the connectors into place.
The default setting for the wiring configurations is auto-MDI/MDI-X.
The default setting is appropriate for switch ports that are
connected to 10/100Base-TX network devices that also support
auto-MDI/MDI-X.
The default auto-MDI/MDI-X setting is not appropriate for switch
ports that are connected to 10/100Base-TX network devices that
do not support auto-MDI/MDI-X and have a fixed wiring
configuration. For switch ports connected to those types of network
devices, you should disable auto-MDI/MDI-X and set the wiring
configurations manually.
The appropriate MDI/MDI-X setting for a switch port connected to a
10/100Base-TX network device with a fixed wiring configuration
depends on the setting of the network device and whether the
switch and network device are connected with straight-through or
crossover cable. If you are using straight-through copper cable, the
wiring configurations of a port on the switch and a port on a
network device must be opposite each other, such that one port
uses MDI and the other MDI-X. For example, if a network device
has a fixed wiring configuration of MDI, you must disable auto-MDI/
MDI-X on the corresponding switch port and manually set it to
MDI-X. If you are using crossover copper cable, the wiring
configurations of a port on the switch and a port on a network
device must be the same.
The default speed setting for the ports is Auto-Negotiation. This
setting is appropriate for ports connected to network devices that
also support Aut-Negotiation.
The default speed setting of Auto-Negotiation is not appropriate for
ports connected to 10/100Base-TX network devices that do not
support Auto-Negotiation and have fixed speeds. For those switch
ports, you should disable Auto-Negotiation and set the port’s
speed manually to match the speeds of the network devices.
The 10/100/1000Base-T ports must be set to Auto-Negotiation, the
default setting, to operate at 1000Mbps.
The default duplex mode setting for the ports is Auto-Negotiation.
This setting is appropriate for ports connected to network devices
that also support Auto-Negotiation for duplex modes.
