FCC Warning
This equipment has been tested and found to comply with the limits for a Class-A digital device, pursuant to Part
15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses, and can radiate radio frequency energy. It may cause
harmful interference to radio communications if the equipment is not installed and used in accordance with the
instructions. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and receiver.
 Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
 Consult the dealer or an experienced radio/TV technician for help.
Caution: Any changes or modifications not expressly approved by the grantee of this device could void the user's
authority to operate the equipment.
CE Mark Warning

1. Overview
Antaira’s LNX-800A industrial unmanaged Ethernet switch series are IP30 rated and DIN-Rail
mountable. Each unit is designed with five 10/100Tx Fast Ethernet ports, which the RJ-45 interface
provides auto detection of MDI or MDI-X, and each port builds with data memory buffers that support
the store-and-forward mechanism.
The LNX-800A series provides high EFT and ESD protection to prevent any unregulated voltage and
is suitable for harsh environments. It supports the power redundancy feature using a dual power input
design with reverse polarity protection.
In addition, the built-in relay warning function alerts maintainers when power failures or port breaks
occur.
The LNX-800A series includes two models: one with an operating temperature range of -10 to 70°C,
and the other one with an extended operating temperature range of -40 to 75°C. It is a perfectly
designed product to fulfill special needs for industrial automation, outdoor applications and harsh
weather environments.

2.4 LED Indicators
There are LED light indicators located on the front panel of the industrial Ethernet switch that
display the power status and network status. Each LED indicator has a different color and has
its own specific meaning, see below in Table 2.1.
LED Color Description
P1 Green On Power input 1 is active
Off Power input1 is inactive
P2 Green On Power input 2 is active

2.5 Ethernet Ports
 RJ-45 Ports
RJ-45 Ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for 10Base-T, 100Base-TX
devices 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 as below
for straight-through and crossover cabling schematics.

All ports on this industrial Ethernet switch support automatic MDI/MDI-X operation. Users can use
straight-through cables (see figure below) for all network connections to PCs, servers, other
switches or hubs. With straight-through cable, pins 1, 2, 3, and 6, at one end of the cable are
connected straight through to pins 1, 2, 3 and 6 at the other end of the cable. The table below
(Table 2.3) shows the 10BASE-T, 100BASE-TX MDI and MDI-X port pin outs.
Pin MDI-X Signal Name MDI Signal Name
1 Receive Data plus (RD+) Transmit Data plus (TD+)
2 Receive Data minus (RD-) Transmit Data minus (TD-)
3 Transmit Data plus (TD+) Receive Data plus (RD+)
6 Transmit Data minus (TD-) Receive Data minus (RD-)
The following figures show the cabling schematics for straight-through and crossover.
