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. 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
.
When logging into the GUI or the CLI for the first time, the switch will
prompt you to change the default password to a new one. The new password
must meet the following complexity requirements:
Minimum 8 characters and maximum 35 characters in password
length without leading or trailing blanks.
The password must contain characters from the following categories:
1. Uppercase English letters, (A to Z)
2. Lowercase English letters, (a to z)
3. Numbers, (0 to 9)
4. Non-alphanumeric characters (e.g. @,#,$), but not including
(”, ?, !)

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.” The system
information screen will display.

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.
