Allied Telesis AT-8550SP - Manual (Page 16)

Overview
16
AT-8550SP The 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 expansion slots for two Small Form-factor Pluggable
(SFP) modules. You can use the slots to add 1000Base-X fiber optic ports
to the switch. For a list of supported SFP modules, 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 SFP modules are installed and establish links with their end
nodes. A link on a SFP port always takes precedence over that of the
corresponding 10/100/1000Base-T twisted pair port.
