The IGS-803SM is an Industrial Gigabit Ethernet Switch (IGS) for commercial temperature range of -10°C to +60°C. There are 8 LAN ports with RJ-45 connectors that support 10M/100M/1000M Ethernet. There are 3 fibre ports that support 100M/1000M dual rate speed and utilize SFP cages that support any industry standard Fast or Gigabit SFP module. The Ethernet switch is fully manageable; supporting most standard Layer 2 Ethernet configurable settings). The IGS-803SM-E model is identical in every way, except it can support an extended operating temperature range of - 40°C to +75°C.

These models are managed industrial grade GbE L2+ switches with 8/4 10/100/1000Base-T ports plus 3/4 GbE/100M Ethernet SFP ports 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 networks, security automation applications, intelligent transportation systems (ITS) and are also suitable for many military and utility market applications where environmental conditions exceed commercial product specifications (See Figure 1).

1588 Precision Time Protocol

These switches  support IEEE 1588 PTP V2 for precise time synchronization.  Each port may be configured independently  to operate in Ordinary-Boundary,  Peer to Peer Transparent Clock,  End to End Transparent Clock, Master, or Slave mode.  Accuracy is measured in nanoseconds, making it suitable for time sensitive applications such as mobile phone networks, military systems and large scale financial networks.

PoE Switch Application

Console Port Connection

The IGS-403 has an asynchronous terminal console port for local management via a serial terminal. The terminal provides management via a CLI (Command Line Interface) which will be familiar to many networking engineers. For most users, the CLI can be used to initially configure TCP/IP access so that further configuration can be completed via the GUI (Graphical User Interface) and any web browser. 


The units are equipped with both RADIUS and TACACS+ authentication for use in sensitive networks where security is paramount. SSL & SSH2 are also supported.
