The switch is a plug-and-play Hardened Gigabit Ethernet
Switch in compact size. It doesn't have any complicated
software to set up.

This manual describes how to install and use the Hardened
Gigabit Ethernet Switch. This switch integrates full wire speed
switching technology. This switch brings the answer to
complicated hardened networking environments.

To get the most out of this manual, you should have an
understanding of Ethernet networking concepts.

In this manual, you will find:

 Features on the switch
 Illustrative LED functions

Installation

This chapter gives step-by-step instructions about how to
install the switch:

Selecting a Site for the Switch

As with any electric device, you should place the switch
where it will not be subjected to extreme temperatures,
humidity, or electromagnetic interference. Specifically, the site
you select should meet the following requirements:

 The ambient temperature should be between -40 to 75

degrees Celsius.

 The relative humidity should be less than 95 percent,

non-condensing.

 Surrounding electrical devices should not exceed the

electromagnetic field (RFC) standards.

 Make sure that the switch receives adequate ventilation.

Do not block the ventilation holes on each side of the
switch.

 The power outlet should be within 1.8 meters of the

switch.

13

EX42908 series www.etherwan.com

DIN Rail Mounting

Installation: Place the switch on the DIN rail from above using
the slot. Push the front of the switch toward the mounting
surface until it audibly snaps into place.

Removal: Pull out the lower edge and then remove the switch
from the DIN rail.

14

EX42908 series www.etherwan.com

Connecting to Power

DC Terminal Block Power Inputs

 Connect the DC power cord to the plug-able terminal

block on the switch, and then plug it into a standard DC
outlet.

 Disconnect the power cord if you want to shut down the

switch.

CAUTION: This equipment is designed to permit the
connection of the earthed conductor of the DC supply circuit
to the earthing conductor at the equipment.

If this connection is made, all of the following conditions must
be met:

15

EX42908 series www.etherwan.com

 This equipment shall be connected to directly to the DC

supply system earthing electrode conductor or to a
bonding jumper from an earthing terminal bar or bus to
which the DC supply system earthing electrode conductor
is connected.

 This equipment shall be located in the same immediate

area (such as, adjacent cabinets) as any other equipment
that has a connection between the earthed conductor of
the same DC supply circuit and the earthing conductor,
and also the point of earthing of the DC system. The DC
system shall not be earthed elsewhere.

 The DC supply source is to be located within the same

premises as the equipment.

 Switching or disconnecting devices shall not be in the

earthed circuit conductor between the DC source and the
point of connection of the earthing electrode conductor.
