Installing a SIM Card for Models SF400 and SF800
SIM (Subscriber Identity Module) cards are required for the MultiModem iSMS to operate on a GPRS network. This
section describes how to install the SIM card.
Before You Begin
Perform the procedure that follows—removal of chassis cover—only at an ESD workstation using an antistatic wrist strap.
If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it
to a metal ground screw (lug) next to power switch of MultiModem iSMS chassis.
1. Power off the unit and unplug the power cord.
2. Do not remove protective power supply cover. Harmful voltages may be exposed if cover is removed, and can lead to
electrical shock and or death.
Electrostatic discharge (ESD) is the release of stored static electricity that can damage electrical circuitry or components.
Static electricity is often stored in your body, and discharged when you contact an object of a different potential.
3. Use a small screwdriver to remove the six (6) screws on the back of the MultiModem iSMS. The figure that follows
uses red circles to indicate the location of these screws.
4. Lift the top cover from the back of the unit and then slide towards the front to remove.
5. Insert the SIM cards into the SIM card slots on the internal wireless modems. Each modem has a graphic line
depicting the correct SIM card orientation.
6. The figure that follows uses two red boxes to indicate the location of these receptacles. Note that the SF800 model is
used in the figure.
7. To re-attach the cover, tilt the cover up and align the “teeth” with the gaps between those on the bottom of the
chassis. The illustration uses red arrows to indicate the locations to align.
8. Rotate the cover down and push it toward the rear of the unit until it is flush.
9. Insert the six (6) screws back in to the unit and tighten.

Rack or Wall Mounting (SF400/800)
The MultiModem SF400/800 units can be rack (or wall) mounted with screws using the mounting brackets.
Rack Mounting
Ensure proper installation of the unit in a closed or multi-unit enclosure by following the recommended installation as
defined by the enclosure manufacturer. Do not place the unit directly on top of other equipment or place other
equipment directly on top of the unit. If installing the unit in a closed or multi-unit enclosure, ensure adequate airflow
within the rack so that the maximum recommended ambient temperature (50° C) is not exceeded. Ensure that the unit is
properly connected to earth ground by verifying that it is reliably grounded when mounted within a rack. If a power strip
is used, ensure that the power strip provides adequate grounding of the attached apparatus.
When mounting the equipment in the rack, make sure mechanical loading is even to avoid a hazardous condition. The
rack used must safely support the combined weight of all the equipment it supports.
Ensure that the mains supply circuit is capable of handling the load of the equipment. See the power label on the
equipment for load requirements.
Ensure that only properly qualified service personnel install this equipment. Only connect like circuits - connect SELV
(Secondary Extra Low Voltage) circuits to SELV circuits and TN (Telecommunications Network) circuits to TN circuits.
Note: The ambient temperature of the rack interior must not exceed 50° Celsius.

Chapter 2 – Setting up and using the
iSMS
Setting Up Your MultiModem iSMS
New MultiModem iSMS units are preconfigured with an IP address of 192.168.2.1 and a 24 bit subnet mask
(255.255.255.000).
Before connecting your new MultiModem iSMS to your network and powering it up, identify the existing IP network
numbering scheme of the target network. If the target network already implements a 192.168.2.xxx class C network, the
unit's host IP address of 192.168.2.1 may conflict with an existing computer or device on the network. Additionally,
advanced network configurations may block IP packets not of the current scheme. For example, if the current network
configuration is 10.1.x.x/16, any IP packets not of this subnet are blocked.
If either is the case, temporarily isolate a workstation and the new MultiModem iSMS from the target network. Connect
the Ethernet interface of the workstation directly to the Ethernet interface of the MultiModem iSMS. After configuring
the MultiModem iSMS with appropriate IP network parameters (IP address, subnet mask, default gateway and DNS), you
can connect the MultiModem iSMS to the target network.
Note: Be sure to perform a "Save to Flash" before powering off the unit, if you are physically moving the unit to a new
location.
The MultiModem iSMS LAN connection is a full duplex, auto negotiating 10/100 MHz, auto polarity sensing Ethernet
interface. You can use a traditional straight through RJ-45 Ethernet cable or a cross-over RJ-45 Ethernet cable when
connecting to an Ethernet port on a hub or switch or when connecting directly to the Ethernet interface of a workstation.
The LAN connection of the MultiModem iSMS does not support POE (Power over Ethernet) or 1GHz. These features may
need to be disabled on the equipment/port that the MultiModem iSMS is connected to.
You must cable and then configure your device:
●Basic cabling and TCP/IP directions are included in this chapter.
●Chapter 3 describes basic configurations.
●Chapter 4 describes advanced configurations.

Chapter 2 – Getting Started
17 MultiModem® iSMS Administrator’s Guide
SF100 Cabling
1. Plug one end of a RJ-45 cable into the LAN port on the MultiModem iSMS and the other end into your network or
workstation interface.
2. Attach the cellular antenna.
3. Connect the provided power supply cable to the 9 volt power port on the back of the MultiModem iSMS, and plug
the other end into an AC power outlet.
About 30 seconds after you apply power, the unit’s front panel Status and LAN LEDs report normally. For more
information about the LEDs, see Chapter 1.
Antenna Notes:

Establishing TCP/IP Communication
Use an IP enabled workstation with an Internet browser to setup and manage the MultiModem iSMS.
Your workstation needs to be configured with a 192.168.2.xIP address and subnet mask of 255.255.255.000, to be able to
communicate with a new (or factory defaulted) MultiModem iSMS (where xis not the number 0, 1, or 255, nor any other
host number that may already be in use by another computer or device on the 192.168.2.x subnet).
Note: When configuring your workstation with a 192.168.2.x IP address (either as an alias address or as the primary fixed
address) and when the workstation is not separated by a router or firewall from the MultiModem iSMS (that is, the units
are on the same local network), the workstation does not need to be configured with a default gateway address (default
route).
This section describes how to setup a Windows XP workstation so it can communicate with the MultiModem iSMS.
Setting a Fixed IP Address
1. Make the MultiModem iSMS connections.
2. From the Start menu, select Settings then Control Panel.
3. In the control panel, double-click Network Connections. The Network Connections window opens.
4. Right click the Local Area Connection icon and select Properties from the drop down list.
