Cabling
Each 10/100/1000BASE-T port uses an RJ45 socket (similar to phone jacks) for
connection of unshielded twisted-pair cable (UTP). The IEEE 802.3/802.3u 802.3ab
Fast/Gigabit Ethernet standard requires Category 5 UTP for 100 Mbps 100BASE-TX.
10BASE-T networks can use Cat.3, 4, 5, or 1000BASE-T use 5/5e/6 UTP (see table
below). Maximum distance is 100 meters (328 feet). The 100BASE-FX/1000BASE-
SX/LX SFP slot uses an LC connector with optional SFP module. The table below
provides cable specification details.

Ethernet devices like hubs and PCs can connect to the industrial managed switch by
using straight-through wires. The two 10/100/1000Mbps ports are auto-MDI/MDI-X and
can be used on straight-through or crossover cable.
Installing the SFP/SFP+ transceiver
SFP transceivers are hot-pluggable and hot-swappable. They can be plugged in and
removed to/from any SFP port without having to power down the industrial managed
switch (see below).
Approved Interlogix SFP transceivers
The industrial managed switch supports both single mode and multi-mode SFP
transceivers. The following list of approved Interlogix SFP transceivers is valid as of the
