Switch

Unpacking

Open the carton and unpack the items. Your package should include:

▪ One EX78900H hardened managed switch

▪ One RJ-45 console cable

If any items are missing or damaged, notify your EtherWAN representative. If

possible, save the carton and packing material in case you need to ship or store the

switch in the future.

What Else You Need

▪ Appropriate cables for data ports. To prevent damage to the switch from

electrical surges, it is recommended to use STP (Shielded twisted pair)

cabling.

▪ Personal computer or laptop

▪ Appropriate SFP modules for SFP ports

Select a Location

▪ Installations: DIN-Rail mount.

▪ Select a power source within 6 feet (1.8 meters).

▪ Choose a dry area with ambient temperature between -40 and 75ºC (-40

and 167ºF).

▪ For use at altitudes up to 2000 meters, indoor use only.

▪ Humidity range (Operational): 5% to 95%, non-condensation

Connect to the Data Ports

Depending on the model, your switch can have the following ports:

EX78922H-0VB

8-port 10/100/1000BASE-T (4 x 30W, 4 x 90W PoE)

2-port 100/1000M SFP

EX78924H-0VB

8-port 10/100/1000BASE-T (4 x 30W, 4 x 90W PoE)

4-port 100/1000M SFP

EX78934H-0VB

12-port 10/100/1000BASE-T (8 x 30W, 4 x 90W) PoE

4-port 100/1000M SFP

10/100/1000BASE-TX (PoE) Ports

Ports that support Power over Ethernet provide power to networked devices such

as IP Phones, Wireless LAN Access Points, and IP security cameras with a power

budget of 360 Watts.

PoE 90W Limitation

When using PoE ports at 90 Watts, use PoE ports – 1, 4, 8, and 9 for 90W PoE. See

example below:

100M/1000M SFP Ports

SFP transceivers can be installed directly into SFP slots. Ensure that the same type

of transceiver is used at both ends of the link and that the correct type of fiber

cable is used.

Connect Power

▪ The switch has two pairs of power inputs.

▪ Only one power input is required to operate the switch. However,

redundant power supply functionality is supported.

▪ Power rating: 52V/4.97A 57V/4.54A

▪ Note: Use qualified power supply by SELV or double insulation of UL 60950

or UL 61010-1 or UL 61010-2-201 standards.

Terminal Block

The switch provides two power inputs on a 52-57VDC terminal block. The

terminal block has 5 terminal posts.
