EX75900 Series | Hardened Managed PoE Ethernet Switch
Unpacking
Open the carton and unpack the items. Your package should include:
▪One EX75900 switch
▪One RJ-45 console cable
▪Rack-mounting hardware brackets
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
Select a Location
▪Desktop installations: Mount on a flat table or shelf surface.
▪Rack installations: Use a 19-inch (48.3-centimeter) EIA standard equipment
rack that is grounded and physically secure.
▪Choose a dry area with ambient temperature between -40 and 75ºC (-40
and 167ºF).
▪Keep away from heat sources, sunlight, warm air exhausts, hot-air vents,
and heaters.
▪Be sure there is adequate airflow.
Connect to the Data Ports
Depending on the model, your switch can have the following ports:
▪24 10/100/1000Base-TX PoE ports
▪4 1G SFP or 4 1G/10G SFP slots
10/100/1000BASE-TX Ports
Ports that support Power over Ethernet provide power to networked devices such
as IP Phones, Wireless LAN Access Points, and IP security cameras. Total power
budget is 720 Watts, 60 Watts per port.
1G/10G 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 DC Power
The switch has two terminal block power inputs. Only one power input is required
to operate the switch. However, redundant power supply functionality is
supported. Input voltage is 52-57 VDC.
Relay Output Alarm
The switch provides relay output contacts for signaling of a user-defined power or
port failure. The relay output can be connected to an alarm signaling device.
Current is 0.5A at 48VDC.
3 Normal Open | 2 Ground | 1 Normal Close

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
Logic level 0: Open
Wet Contacts:
[DI1+/DI1-] [DI2+/DI2-]
Logic level 1 (High): 13~30 Volts
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.

Installation Guide
EX75900 Series | Hardened Managed PoE Ethernet Switch
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 DB-9 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
Connect to the switch using either one of the RJ45 ports on the front, or the
console port on the rear of the device.
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.”
Copy Configuration to USB
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.
Safety Information
This equipment is intended to be used in a restricted access location and by
qualified personnel. This equipment is not suitable for use in locations where
children are likely to be present.
Pluggable optical modules and direct-attach cables shall meet the following
regulatory requirements:
• UL and/or CSA registered component for North America
• Class 1 Laser Product
• FCC 21 CFR Chapter 1, Sub-chapter J in accordance with FDA & CDRH
requirements
• IEC/EN 60825-1:2014, IEC/EN 60825-2:2004+A1+A2 or later, European Standard
(A) Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be
greater than room ambient. Therefore, consideration should be given to installing
the equipment in an environment compatible with the maximum ambient
temperature (Tma).
B) Mechanical Loading - Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
C) Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits
might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing
this concern.
D) Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g. use of power strips).
Do not disable the power cord grounding plug. The grounding plug is an
important safety feature.
