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 5e (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. The fiber
segment using the single-mode connector type must use 9/125 µm single-mode fiber cable. You can connect two
devices up to 32 km apart. The fiber segment using the multi-mode connector type must use 50 or 62.5/125 µm
multi-mode fiber cable. You can connect two devices up to 2 km apart.
Gigabit Copper/SFP (Mini-GBIC) Combo Port
The 5073E-T Switch has three auto-detected gigabit cooper/SFP ports, which are the Mini-GBIC Combo ports.
These ports should use Category 5e (or above) UTP/STP cable for connections up to 1000 Mbps. The small form-
factor pluggable (SFP) is a compact optical transceiver used in optical communications for both telecommunication
and data communications. The SFP slots supporting dual mode can switch the connection speed between 100
and 1000 Mbps, and are used for connecting to the network segment with single or multi-mode fiber. Choose the
appropriate SFP transceiver to plug into the slots, and make sure to use the same type of tranceiver on both of the
SFP ports that you are connecting. For a list of SFP tranceivers, see “1.3 Order Information” on page 7. Use
proper multi-mode or single-mode fiber, according to the transceiver. Fiber optic transmits at speed up to 1000
Mbps and prevents noise interference.
