AT-8500 Series Layer 2+ Fast Ethernet Switches Installation Guide

AT-8550SPThe AT-8550SP switch has 48 10/100Base-TX twisted pair ports with RJ-45 connectors. The ports have a maximum operating distance of 100 meters (328 feet) using Category 3 or better 100 ohm twisted pair cable for 10Base-T operation and Category 5 or 5E 100 ohm twisted pair cable for 100Base-TX operation.

The switch also features two 10/100/1000Base-T twisted pair ports, labelled Ports 49R and 50R. They have RJ-45 connectors, require Category 5 or 5E 100 ohm twisted pair cable, and have a maximum operating distance of 100 meters (328 feet).

There are also two slots for two Small Form-factor Pluggable (SFP) transceivers. You can use the slots to add 1000Base-X fiber optic ports to the switch. For a list of supported SFP transceivers, contact your Allied Telesis sales representative or refer to the Allied Telesis web site: www.alliedtelesis.com.

Note

The twisted pair ports 49R and 50R change to a redundant status when SFP transceivers are installed and establish links with their end nodes. A link on an SFP port always takes precedence over that of the corresponding 10/100/1000Base-T twisted pair port.

Figure 5 shows the front and back panels of the AT-8550GB switch.
