1. Overview
Antaira Technologies’ LMX-2828G-10G-SFP is a 28-port industrial managed Ethernet switch
embedded with 16*gigabit SFP slots, 8*gigabit combo ports (8*10/100/1000Tx RJ45 and
8*100/1000 SFP slots), and 4*10G SFP+ slots. This switch supports layer 3 routing protocols
like RIP and OSPF, along with a static routing table. The LMX-2828G-10G-SFP has other
functions like RSTP for network redundancy, IGMP, VLAN, QoS, and SNMP features.
The LMX-2828G-10G-SFP is designed for rack-mount installation. It is suitable as a backbone
fiber aggregation switch. This product is ideal for supporting applications that require high-
density port connections, such as, security surveillance, traffic monitoring systems, facility
management in power/utility, water wastewater treatment plants and oil/gas/mining.

2.5 Ethernet Ports
◼RJ45 Ports (Auto MDI/MDIX):
The RJ45 ports are auto-sensing for 10/100/1000Base-Tx device connections. Auto MDI/MDIX
means that the switch can connect to another switch or workstation without changing the straight-
through or crossover cabling. See the figures shown below for straight-through and crossover
cabling schematics.
◼RJ45 Pin Assignments (Figure 2.2 & 2.3)
The following figures show the cabling schematics for straight-through and crossover cables.
The following figures show the 10,100, and 1000 Ethernet RJ‐45 pin outs.
