Unpacking
Open the carton and unpack the items. Your package should include:
One EX78900E 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:
EX78922E-0VB
8-port 10/100/1000BASE-T (4 x 30W, 4 x 60W PoE)
2-port 100/1000M SFP
EX78924E-0VB
8-port 10/100/1000BASE-T (4 x 30W, 4 x 60W PoE)
4-port 100/1000M SFP
EX78934E-0VB
12-port 10/100/1000BASE-T (8 x 30W, 4 x 60W) 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 240 Watts.
100/1G 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 UL60950
or UL61010-1 or UL61010-2-201 standards.
Terminal Block
The switch provides two power inputs on a 52-57VDC terminal block. The
terminal block has 5 terminal posts.

Relay Output Alarm
The switch provides two relay output contacts. Both Relay 1 and Relay 2 signal
actions from one of the digital inputs. The relay outputs can be connected to an
alarm signaling device. The Current is 0.5A@48VDC at Normal Open or Normal
Close.
3 Normal Open | 2 Ground | 1 Normal Close
Power-Up Sequence
When the switch is powered up:
All Link/ACT LEDs blink momentarily.
The Power 1 LED light goes ON.
LEDs for every port connected to a device will flash, as the switch conducts a
brief Power On Self-Test (POST).

Digital IO-Setting
Connecting the Digital Inputs
The pin definitions for the digital input module are shown below. Each digital input
consists of two contacts on the 5-pin connector located on the top of the switch. The
inputs can be wired as either dry or wet contacts.
Dry Contacts:
[DI1-/GND] [DI2-/GND]
Logic level 1: Close to GND(10mA)
Logic level 0: Open
Wet Contacts:
[DI1+/DI1-] [DI2+/DI2-]
Logic level 1 (High): 13~30 Volts (3.2mA)
Logic level 0 (Low): 0~3 Volts
Configuring Digital Input Alarms Using the Web Interface
Located under the Diagnostics group, the Digital IO-Setting page allows for quick
configuration and enabling of digital input and environmental alarms.
To enable digital input alarms globally:
1. Choose Enable from the drop down menu in the Set State field.
2. Click on the Update Setting button to the right of the field.
To enable specific digital input alarms:
1. Enter a name or description of the alarm in the Description field.
2. In the Alert field, choose Enable/High from the drop-down menu if you want
the alarm to trigger in an occurrence of high voltage (wet contact), or Open state
(dry contact). Choose Enable/Low if you want the alarm to trigger in an
occurrence of low voltage (wet contact), or Closed to ground state (dry contact).
3. To set alarms for temperature and humidity, enter the threshold value in the
field provided, and select Enable from the drop down menu at the right.
4. Click on the Update Setting button at the bottom right to put the new settings
into effect. Then navigate to the Email configuration page.
Console Configuration
Connect to the switch console by connecting the RJ-45 console cable to the
console port of the switch and to the serial port of the computer running a
terminal emulation application (such as HyperTerminal or Putty).
Configuration settings of the terminal-emulation program: Baud rate:
115,200bps, Data bits: 8, Parity: none, Stop bit: 1, Flow control: none.
The default login name is “root,” no password.
Web Configuration
Log in to the switch by launching a web browser and entering 192.168.1.10 in the
address bar. Enter the default login ID: root (no password) and click “Login.”
USB Port
The switch is equipped with one USB port (Type A connector) for configuration
file and syslog backup. The USB port can be used to save the configuration and
Syslog to a (FAT32) USB storage device.
Plug the device into the USB port, and use the “Save Configuration” command in
the web interface, or “copy running-config startupconfig” in the CLI. Use the
“Export Logs to USB” command in the web interface, or “export logs” in the CLI.
Other Information
