Grounding the Industrial Rackmount Switch
Grounding and wire routing help limit the effects of noise from
electromagnetic interference (EMI). Run the groun d connect ion from th e
ground screw to the grounding surface prior to connecting devices.
Connecting the Power Inputs
The ICS supports dual redundant p ower supplies: Power Supply 1 (PWR1)
and Power Supply 2 (PWR2). The connections for PWR1 and PWR2 are
located on the rear of the product. Be sure t o use a standard power cord
with an IEC C13 connector, which is compatible with the AC power in l et.

Installing/Removing ICS Switch Modules
IM-G7000A Series modules are designed for installation in ICS switches.
Before inserting the module into the slot, first remove the metal cover
plate. Push the module along the track and firmly connect the module
with the connector. Finally, secure the modul e by firmly tightening the
screws.
IM-G7000A Series modules are hot-swappable. Take the following steps
to remove modules from the switch:
1. Push the HOT SWAP button on the module.
2. Wait for the HOT SWAP STATE LED to turn off.
3. Loosen the screw(s) and remove the module.
Wiring the Relay Contact
Each ICS switch has one relay output.
FAULT: The relay contact of the 4-pin terminal block connector is used to
detect user-configured events. The two wires attached to the fault
contacts form an open circuit when a user-conf igur ed event is triggered.
If a user-configured event does not occur, the fault circu it remains closed.
USB Console Connection
The ICS has one USB console port (type B connect or) locate d on th e to p
panel. Use the USB cable (provided in the product package) to connect
the ICS’s console port to your PC’s USB port, and install the USB driver
(available on the software CD) on the PC. You may then use a console
terminal program, such as Moxa PComm Terminal Emulator, to acces s the
ICS’s console configuration utility.
USB Console Port (Type B Connector) Pinouts
USB Storage Connection
The ICS has one USB storag e port (type A c onnector) on the front p anel.
Use Moxa’s ABC-02-USB automatic backup configurator to connect t h e
ICS’s USB storage port for configuration backup, firmware upgrade, or
system log file backup.
USB Storage Port (Type A Connector) Pinouts
DO NOT remove the ABC-02-USB USB Automatic Backup
Configurator while writing or reading data.

Reset Button
Depress the Reset button continuously for five seco nds to load the factory
default settings. Use a pointed object, such a s a straightened paper clip or
toothpick, to depress the Reset button. When y ou do so, the STATE LED
will start to blink about once per second. Continue t o depress t he ST ATE
LED until it begins blinking more rapidly, which indicates that the button
has been depressed for five second s and you can release the Reset b utton
to load factory default settings.
DO NOT power off the switch when loading default settings.
System has passed the self-diagnosis test
on boot-up and is ready to run.

Rack Mounting Instructions
1. Elevated Operating Ambient: If installed in a closed or multi-unit
rack assembly, the operating ambient temperature of the rack
environment may be greater than room a mbient. Therefore,
consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
2. Reduced Air Flow: Installation of the equipment in a rack should be
such that the amount of air flow required for safe operation of the
equipment is not compromised.
3. Mechanical Loading: Mounting of the equipment in the rack shou ld
be such that a hazardous condition is not achieved due to uneven
mechanical loading.
4. Circuit Overloading: Consideration should be given to the
connection of the equipment to the supply circuit and the effect that
overloading of the circuits might have on overcurre nt prote ct ion and
supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
5. Reliable Earthing: Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply
connections other than direct connections to the b ranch circuit (e.g .,
use of power strips).
Restricted Access Locations
• This equipment is intended to be used in Restricted Access Locations,
such as a computer room, with access limited to SERVICE
PERSONNEL or USERS who have been instructed on how to handle
the metal chassis of equipment that is so hot that special protection
may be needed before touching it. The location should only be
accessible with a key or through a security identity system.
• External metal parts of this equipment are extremely hot!! Before
touching the equipment, you must take special precautions to protect
your hands and body from serious injury.
