Overview
LevelOne IES-1881 Industry Ethernet Switch provides 16 PoE
ports of 10/100Base-TX plus 2 Combo ports of 1000Base-T
Gigabit Ethernet and 1000Base-LX SM SC fiber to enable high
speed network at mission-critical environment. With the 1U
height rack-mountable size, this switch can be easily installed
in the cabinet, plus the clearly visible status LEDs provide
simple monitoring of port link activity.
High Reliability
All components are built to withstand harsh environment
applications without compromise where humidity, temperature
variation and even shock vibration are concerns, including
Electric & Utility, Critical Infrastructure, Transportation and
Surveillance Security. This device operates under -40 to 75
Celsius (-40 to 167 Fahrenheit) temperature.
Power over Ethernet
This switch is Power Sourcing Equipment (PSE), and it is fully
complied with IEEE 802.3at PoE standard at maximum 30W
power budget per port. It helps to save infrastructure wiring
costs dramatically by eliminating electric wiring and less UPS
needed.
Management
Supports a variety of management features including: CLI via
Console or Telnet; Graphic User Interface via Web Browser or
Simple Network Management Protocol via SNMP tools. It
provides better visibility and management of those critical
assets.

Console Configuration
1. Connect to the switch console:
2. Connect the DB9 straight cable to the RS-232 serial port of
the device and the RS-232 serial port of the terminal or
computer running the terminal emulation application. Direct
access to the administration console is achieved by directly
connecting a terminal or a PC equipped with a terminalemulation program (such as HyperTerminal) to the switch
console port.
3. Configuration settings of the terminal-emulation program:
4. Baud rate: 115,200bps, Data bits: 8, Parity: none, Stop bit: 1,
Flow control: none.
5. Press the “Enter” key. The Command Line Interface (CLI)
screen should appear as below:
6. Logon to Exec Mode (View Mode):
7. At the “switch_a login:” prompt just type in “root” and press
<Enter> to logon to Exec Mode (or View Mode). And the
“switch_a>” prompt will show on the screen.
8. Logon to Privileged Exec Mode (Enable Mode):
9. At the “switch_a>” prompt just type in “enable” and press
<Enter> to logon to Privileged Exec Mode (or Enable Mode).
And the “switch_a#” prompt will show on the screen.
10. Logon to Configure Mode (Configure Terminal Mode):
11. At the “switch_a#” prompt just type in “configure terminal”
and press <Enter> to logon to Configure Mode (or Configure
IES-1881 Page 6
Terminal Mode). And the “switch_a(config)#” prompt will
show on the screen.
12. Set new IP address and subnet mask for Switch:
13. At the “switch_a(config)#” prompt just type in “interface
vlan1.1” and press <Enter> to logon to vlan 1 (vlan1.1 means
vlan 1). And the “switch_a(config-if)#” prompt will show on
the screen.
14. Command Syntax: “ip address A.B.C.D/M”. “A.B.C.D”
specifies IP address. “M” specifies IP subnet mask. “M”= 8:
255.0.0.0, 16:255.255.0.0, or 24: 255.255.255.0.
15. For example, At the “switch_a(config-if)#” prompt just type
in “ip address 192.168.1.10/24” and press <Enter> to set
new IP address (192.168.1.10) and new IP subnet mask
(255.255.255.0) for Switch
