The AT-8550GB switch has 48 10/100Base-TX twisted pair ports, capable
of operating at either 10 or 100 Mbps, with RJ-45 connectors. These
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).
The switch also has two expansion slots for two Gigabit Interface
Converter (GBIC) expansion modules. You can use the modules to add
1000Base-X fiber optic ports to the switch to extend the distance of your
network. For a list of GBIC modules supported by the switch, contact
your Allied Telesyn sales representative or refer to the Allied Telesyn web
site: www.alliedtelesyn.com.
Note
The twisted pair ports 49R and 50R change to a redundant status
when GBIC modules are installed and establish links with their end
nodes. A link on a GBIC port always takes precedence over that of
the corresponding 10/100/1000Base-T twisted pair port.
