Twisted-Pair Port Cables

72
Here are the guidelines to cabling the 10/100/1000Base-T twisted-pair
ports:
The ports have 8-pin RJ45 connectors.

The connectors on the cables should fit snugly into the ports, and

the tabs should lock the connectors into place.
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.
The default duplex mode setting of Auto-Negotiation is not

appropriate for ports connected to network devices that do not
support Auto-Negotiation and have a fixed duplex mode. Disable
Auto-Negotiation on those ports and set their duplex modes
manually to avoid the possibility of duplex mode mismatches. A
switch port using Auto-Negotiation defaults to half-duplex if it
detects that the end node is not using Auto-Negotiation. This can
result in a mismatch if the end node is operating at a fixed duplex
mode of full-duplex.
The default wiring configuration of the ports is automatic MDIX

detection, which configures the MDI/MDIX setting automatically.
This setting is appropriate for switch ports that are connected to
network devices that also support the feature.
The Twisted-Pair Standard Cable Requirements for non-PoE and

PoE wiring are given in Table 17 on page 102 and Table 18 on
page 103.
Note
The default setting for the AT-IS230-10GP switch PoE ports is
enabled. The AT-IS130-6GP switch PoE ports are always enabled.
