The IGS is a two-port multiprotocol router in a fixed configuration system. This compact router is available either with an Ethernet connection and a single synchronous serial port, or with two Ethernet connections, and supports a number of serial interfaces.
The IGS features an MC68020 processor running at 16 MHz. There is no separate processor card for the IGS; this server is a single-card unit.
Figure 1-1 shows the IGS chassis from a front view.
