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.
