Introduction
IGS-401F/402F/402S-4PH24 models are non-managed industrial
grade Gigabit PoE (Power over Ethernet) switches that provide stable
and reliable Ethernet transmission. Housed in rugged DIN rail or wall
mountable enclosures, these switches are designed for harsh
environments, such as industrial networking and intelligent
transportation systems (ITS) and are also suitable for many military and
utility market applications where environmental conditions exceed
commercial product specifications. Standard operating temperature
range models (-10°C~60°C) and wide operating temperature range
models (-40°C~75°C) fulfill the special needs of industrial automation
applications.

LAN & Fiber Ports
IGS-401F-4PH(E)24 & IGS-402F-4PH(E)24 models have 4 LAN ports
(labeled 1~4) and one fixed fiber port (labeled FIBER) or two fixed fiber
ports respectively on the front panel. IGS-402S-4PH(E)24 model has 4
LAN ports (labeled 1~4) on the front panel and one optical SFP slot. The
LAN ports that all utilize shielded RJ-45 connectors support
10/100/1000M; while the fixed fiber ports support 1000M and SFP ports
support 100/1000M.
PoE Ports
4 LAN ports (labeled 1~4) 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.

DIP Switch
IGS-401F-4PH(E)24 & 402F-4PH(E)24 use a 2-pole DIP switch for
configuration, while the IGS-402S-4PH(E)24 uses a 4-pole DIP switch for
configuration. Each pole of the switch has the following functions:

Recommended Power, Alarm, Ground Wiring
Scheme
DC Power Connection
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 (PWR1 & PWR2). One power supply is enough to
power up the device. If two power supplies are used, the device
provides power redundancy function. See the figure provided below for
recommended DC power wiring scheme.

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 6. Alarm Relay Wiring
Earth Ground Connection
An earth ground connector is provided on the top 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.

Installation
The switch can be mounted on the wall or installed in DIN rail
depending on your installation needs. When installing the wall-mounting
bracket (optional accessory) and DIN rail bracket, be sure to correctly
align the orientation pin.
Figure 10. DIN Rail Figure 11. Wall Mount
The switch with DIN Rail bracket has a steel spring in the upper rail
of the bracket. This spring is compressed for mounting and un-mounting
by applying downward force.
