Description
IPS 4240 and IPS 4255 deliver high port density in a small form factor. They use a compact flash device for storage rather than the hard-disk drives used in other sensor models
IPS 4240 monitors up to 250 Mbps of aggregate network traffic on multiple sensing interfaces and is inline ready. It replaces IDS 4235. There are four 10/100/1000 copper sensing interfaces
