Twisted-Pair 10/100/1000Base-T Ports
The AT-9000/28 and AT-9000/52 Managed Layer 2 GE ecoSwitch
respectively feature 24 and 48 twisted-pair 10/100/1000Base-T ports. In
addition, four more twisted-pair ports are provided as part of four combo
uplink ports on the AT-9000/28 and AT-9000/28SP and four additional
individual twisted-pair uplinks ports are available on the AT-9000/52.
Note
For an explanation of the combo port functions, go to “Combo Ports”
on page 21
Each twisted-pair port features an 8-pin RJ-45 connector. The ports are
1000Base-T, 100Base-TX and 10Base-T compliant and are capable of
1000 megabits per second (Mbps), 100 Mbps and 10 Mbps speeds.
Note
For the port pinouts, refer to Appendix A, “10/100/1000Base-T
Twisted-Pair Port Connectors” on page 63.
The ports are IEEE 802.3u Auto-Negotiation compliant. With Auto-
Negotiation enabled, 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 1000 Mbps, the switch sets
the port connected to the end node to 1000 Mbps.
The default setting for the twisted-pair ports is Auto-Negotiation, which
automatically determines the duplex mode setting. Each twisted-pair port
on the switches is capable of operating in either half- or full-duplex mode.
In order for the switch to set the duplex mode for each port correctly, the
end nodes that you connect to the switch ports should also use Auto-
Negotiation. Otherwise, a duplex mode mismatch can occur, affecting
network performance. For further information, refer to “Duplex Mode” on
page 29.
Each twisted-pair port has a maximum operating distance of 100 m
(328 feet). For 10 Mbps operation, Category 3 or better 100 ohm shielded
or unshielded twisted-pair cabling is required. For 100 or 1000 Mbps
operation, Category 5 and Enhanced Category 5 (5E) or better 100 ohm
shielded or unshielded twisted-pair cabling is required.
Note
For cable specifications, go to “Twisted-Pair and Fiber Optic Cable
Specifications” on page 36

Overview

SFP Transceiver Slots
All the models in the AT-9000 Managed Layer 2 GE ecoSwitch Series
have slots for Gigabit Ethernet SFP transceivers so that you can connect
the devices across large geographical distances to other Gigabit Ethernet
devices using fiber optic cables.
Figure 4 illustrates a SFP transceiver.
Figure 4. SFP Transceiver
Note
For an explanation of the combo port functions, go to “Combo Ports”
on page 21
Note
For a list of supported SFP transceivers for the AT-9000 products,
contact your Allied Telesis sales representative.
Caution
When you remove an SFP module from this product, the case
temperature of the SFP may exceed 70 C (158 F). Exercise caution
when handling with unprotected hands.
