Chapter 1: Overview

AT-8524MThe 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.

Figure 2 shows the front and back panels of the AT-8524M switch.
