AT-8524M The AT-8524M switch has 24 10/100Base-TX twisted pair ports and two

module expansion slots. The twisted pair ports feature RJ-45 connectors

and 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 expansion slots are compatible with 100Base and 1000Base fiber

optic and twisted pair port expansion modules and the AT-STACKM

stacking module.

AT-8524POE The AT-8524POE switch has 24 10/100Base-TX ports with Power over

Ethernet (PoE) capability. (For a description of this feature, refer to “Power

Over Ethernet” on page 27.) The ports feature RJ-45 connectors and have

a maximum operating distance of 100 meters (328 feet) using twisted pair

cable. The ports, when not using PoE, can use 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. For ports using PoE,

Category 5 or 5E 100 ohm twisted pair cable is required for both 10 and

100 Mbps operation.

The switch also features two expansion slots that are compatible with

100Base and 1000Base fiber optic and twisted pair port expansion

modules and the AT-STACKM stacking module.

AT-8550GB 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 has 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 slots for two Gigabit Interface Converters

(GBICs). You can use the GBICs to add 1000Base-X fiber optic ports to

the switch to extend the distance of your network. For a list of GBICs

supported by the switch, 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 GBICs 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.
