3.5 Wiring the Fault Alarm Contact
The fault alarm contacts are in the middle of the terminal block connector, as shown in Figure 6. Insert the wires
into the fault alarm contacts. After the wires are inserted, the switch detects the fault status of the power failure or
port link failure, and then forms an open circuit. Figure 7 shows an application example for wiring the fault alarm
contacts.
NOTE The wire gauge for the terminal block should be within the range 12–24 AWG.

3.6 Cabling
Use four twisted-pair, Category 5 (or above) cabling for the RJ-45 port connection. The cable between the switch
and the link partner (for example, switch, hub, workstation) must be less than 100 meters (328 ft) long.
