Cabling Guidelines for Twisted Pair Ports
This section applies to the twisted pair ports on the following line cards:
AT-SBx81GT24 Line Card
AT-SBx81GP24 Line Card
AT-SBx81GT40 Line Card
Here are the guidelines to cabling the 10/100/1000Base-T twisted pair
ports on the cards:
The 10/100/1000Base-T twisted pair ports on the AT-SBx81GT24
and AT-SBx81GP24 Line Cards have 8-pin RJ45 connectors.
The 10/100/1000Base-T twisted pair ports on the AT-SBx81GT40
Line Card have 8-pin RJ point 5 connectors.
The cable specifications for the 10/100/1000Base-T twisted pair
ports on the AT-SBx81GT24 and AT-SBx81GT40 Line Cards are
listed in Table 18 on page 65.
The cable specifications for the 10/100/1000Base-T twisted pair
ports on the AT-SBx81GP24 Line Card are listed in Table 19 on
page 66.
The connectors on the cables should fit snugly into the ports, and
the tabs should lock the connectors into place.
The default setting for PoE on the ports on the AT-SBx81GP24
Line Card is enabled.
The default speed setting for the ports is Auto-Negotiation. This
setting is appropriate for ports connected to network devices that
also support Auto-Negotiation.
The default speed setting of Auto-Negotiation is not appropriate for
ports connected to network devices that do not support Auto-
Negotiation and have fixed speeds or 10 or 100 Mbps. For those
switch ports, 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.
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
