Introduction
IGS-2408SM-24PH(E) are industrial grade managed Gigabit PoE
(Power over Ethernet) switches with 24 x 10/100/1000Mbps RJ-45 (with
Power over Ethernet function) + 8 x 100/1000Mbps SFP. Housed in
rugged enclosures, these switches are designed for harsh environments
where environmental conditions exceed commercial product
specifications, such as industrial networking or intelligent transportation
systems (ITS) and are also suitable for many Smart City, surveillance,
intelligent traffic control systems.
These switches are also rack-mountable in 19" rack and support L2
basic and advanced functions, such as ring redundancy (STP/RSTP/
MSTP/ERPS), proprietary u-ring redundancy, time synchronization
(PTPv2) and so on.

Access to Command Line Interface (CLI)
IGS-2408SM-24PH(E) models are managed Gigabit PoE switch
devices. Initial configuration (assignment of IP address) may be
accomplished via the RS-232 console and a PC or laptop running
terminal emulation software or via RJ45 Ethernet port running Telnet or
SSH.
Accessing the switch via CONSOLE or Ethernet port allows the user
to use Command Line Interface (CLI) to manage and configure the device.
This management method is relatively useful when you lose the network
connection to the device. In most configuration scenarios, the console
will only be used to initially configure the IP address, so that the device
may be accessed via the other methods which require working TCP/IP.
See below for useful information for accessing the device via console
and Telnet/SSH connection.
Console Connection
Use the provided accessory cable to connect the "CONSOLE" port
to the PC terminal communications port (DB9). Run any terminal
emulation program (HyperTerminal, PuTTY, TeraTerm Pro, etc.) and
configure the communication parameters as follows:
Speed:
115,200
Data:
8 bits
Parity:
None
Stop Bits:
1
Flow Control:
None
From a cold start, the following screen will be displayed. At the
"Username" prompt, enter “admin”with no password.
To change the default IP address to your desired one (for example,
192.168.0.10/24), issue the following commands:
For complete CLI operation, please refer to the operation manual.
#
# config terminal
(config)# interface vlan 1
(config-if-vlan)# ip address 192.168.0.10 255.255.255.0
Press ENTER to get started
Username: admin
Password:
#

7
Telnet/SSH Connection
To use Command Line Interface (CLI), you can also choose to
access the device through a Telnet/SSH connection via TCP/IP network
over Ethernet ports. For initial operation, use the default TCP/IP settings
(10.1.1.1) to login to the device.
Default TCP/IP settings:
IP Address:
10.1.1.1
Subnet Mask:
255.255.255.0
Username:
admin
Password:
No password (Press "Enter"
key)
To change the default IP address to your desired one (for example,
192.168.0.10/24), issue the following commands:
Once the desired IP address has been configured, a web browser
can be accessed and used to configure the device through a more easy-
to-use GUI (graphical user interface). For complete CLI operation, please
refer to the operation manual.
#
# config terminal
(config)# interface vlan 1
(config-if-vlan)# ip address 192.168.0.10 255.255.255.0

8
Access to Web-Based Management Interface
To enter the web-based management interface for the first time
or after returning the device back to factory defaults, input the default IP
address “10.1.1.1”in your web browser. Then, a standard login prompt
will appear depending on the type of browser used. The example below
is with Firefox browser.
Enter the factory default username “admin”with no password.
After successfully entering the web based management, the Port State
page will appear. For complete Web GUI operation, please refer to the
operation manual.

LAN and Fiber Ports
IGS-2408SM-24PH(E) switches have 24 electrical LAN ports
(labeled 1~24) and 8 fiber ports (SFP based, labeled 25~32) on the front
panel. The LAN ports that utilize shielded RJ-45 connectors support
10/100/1000M; while the fiber SFP ports support 100/1000M.
PoE Ports
All 24 LAN ports support PoE (Power over Ethernet) per
IEEE802.3af (15.4W) or IEEE802.3at (30W) for connection to standard
PoE PD (Power Devices) such as IP Cameras, Access Points, IP Phones,
Digital Signage, etc. PoE eliminates the need to run separate power to
these devices thereby simplifying deployment and reducing expenses.
The LAN ports may also connect to any non-PoE device for normal
Ethernet transmission without any damage to the non-PoE device or to
this device.

CONSOLE Port
The RJ-45 port labeled “CONSOLE” is an RS-232 terminal port for
local management. These models use a “light” CLI (Command Line
Interface) in addition to a user friendly Web interface and industry
standard SNMP.
One RJ-45 to DB-9 cable is provided with this device. CONSOLE
port pinouts and RS-232 DB-9 connector are illustrated below together
with RJ-45 to DB-9 signal mapping information. Use the supplied cable to
connect the RJ-45 CONSOLE port to a console PC.

Alarm Relay Connection
The alarm relay contact can be wired into an alarm circuit which
senses an alarm condition when the contact is broken. The alarm relay is
normally closed when there is no alarm condition. The alarm conditions
are user programmable through management to include power, link
faults or other fault conditions. Please note that the alarm relay contact
can only support 1A current at 24VDC. Do not apply voltage and current
that exceed these specifications.
Figure 5. Alarm Relay Wiring
Earth Ground Connection
An earth ground connector is provided on the rear panel with an
earth ground sign next to it. Grounding the device can help to release
leakage of electricity to the earth safely so as to reduce injuries from
electromagnetic interference (EMI).
Prior to connecting to the power, it is important to connect the ground
wire to the earth. Follow steps below to install ground wire:
1. Loosen or remove the grounding screw.
2. Attach the grounding screw to the ring-type or fork-type
terminal of the grounding cable. Make sure that the
grounding cable is long enough to reach the earth.
3. Use a screwdriver to fasten the grounding screw.
