Twisted Pair
Ports
Figure 3 Twisted Pair Ports
The AT-9410GB Gigabit Ethernet Switch features 10 twisted pair ports.
Type of Connector
All of the twisted pair ports feature RJ-45 connectors. (For the port
pinout details, refer to RJ-45 Port Pinouts in the next section.)
Speed
The 10/100/1000Base-T ports are capable of 10 Mbps, 100 Mbps, or 1000
Mbps speeds. You can set the port speed manually or, since the ports are
IEEE 802.3 Auto-Negotiation compliant, you can let the switch set each
port’s speed automatically. With Auto-Negotiation, the switch
automatically matches the highest possible common speed between
each switch port and each end node. For example, if an end node is
capable of only 10 Mbps, the switch sets the port connected to the end
node to 10 Mbps.
Note
Auto-Negotiation is activated as the default on ports 1 through 10.
To deactivate Auto-Negotiation and set the speeds manually, refer
to the AT-S45 Management Software User’s Guide.

Maximum Distance
Each twisted pair port has a maximum operating distance of 100 m (328
ft).
Type of Cabling
For 10 Mbps operation on the twisted pair ports, Category 3 or better
100 ohm shielded or unshielded twisted pair cabling is required. For 100
or 1000 Mbps operation on the twisted pair ports, Category 5 and
Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair
cabling is required.
Auto-MDI
All of the twisted pair ports on the switch are auto-MDI and IEEE
802.3ab-compatible. They automatically configure themselves as either
MDI or MDI-X when operating at 10 Mbps or 100 Mbps. This feature
allows you to use either straight-through or crossover twisted pair
cables to connect devices to the ports.
Duplex Mode
Each twisted pair port on the switch can operate in either half- or full-
duplex mode. The twisted pair ports are IEEE 802.3u-compliant and will
Auto-Negotiate the duplex mode setting by default. If the end node
connected to a twisted pair port on the switch is capable of full-duplex
operation, the switch sets the port to full-duplex. If the end node is
capable of only half-duplex, the port is set to half-duplex.
If desired, Auto-Negotiation on one or all of the twisted pair ports can be
disabled so that you can set the duplex mode manually through the
switch’s management software.

Expansion Slots
Figure 5 GBIC Expansion Slots
The AT-9410GB Gigabit Ethernet Switch has two expansion slots on the
front panel, labeled GBIC1 and GBIC2. Each slot can accommodate one
optional GBIC module.
A GBIC module is a gigabit (1000Base) transceiver. Figure 6 shows an
example of a fiber optic GBIC module. You can use GBIC modules to
quickly and easily add additional Gigabit Ethernet ports to your switch.
Figure 6 Example of a GBIC Module
GBIC modules can be used to extend the distance of your network, build
a high-speed backbone network, or connect additional nodes to the
network, such as high-speed servers.
The AT-9410GB Gigabit Ethernet Switch supports the AT-G8 series GBIC
modules: SX, LX, LX25, LX40, LX75.
