Connectors
LAN & Fiber Ports
IGS-404SM(-E) have 4 electrical LAN ports (labeled 1
~
4) and 4
fiber ports (SFP based, labeled 5
~
8) 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.
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. See page 5 for basic CLI and Web
operation.
One RJ-45 to DB-9 cable is provided with this device. CONSOLE
port pinouts (Figure 2) and RS-232 DB-9 (Figure 3) 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.

CLI & Web Basic Operation
IGS-404SM(-E) are managed Gigabit Ethernet 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. Configure the terminal as follows:
115200 speed
8 data bits
no parity
1 stop bit
no flow control
IGS-404SM(-E) switches use a command line interface (CLI)
through the serial port. Once the IP address has been configured,
a web browser can be used to configure the device through a
more easy to use GUI (graphical user interface). Please refer to
the operation manual on the CDROM.
Using the provided console cable, connect the RJ-45 to the
“CONSOLE” port and the DB9 to PC COM port. Apply power to the
switch. At the "Username:" prompt, enter '
admin
' (lower case, no
quotes). Just
press Enter when prompted for password
.
To set the IP address and subnet mask, issue the following
commands:
Example: sets VID 1 to 192.168.0.250, subnet 255.255.255.0)
# config terminal
(config)# interface vlan 1
(config-if-vlan)# ip address 192.168.0.250 255.255.255.0
Then, press Enter.
NOTE: The factory default IP address is 10.1.1.1 with mask
255.255.255.0
Power and Alarm
Figure 4. Top Panel
A removable terminal block on the top panel provides both power
and alarm connections. Power can be provided through the dual
inputs from separate sources. 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.
Earth Ground Connection
An earth ground connector is provided on the top panel (See
Figure 4) 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. Remove the grounding screw.
2. Attach the grounding screw to the
ring 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.
