Introducing IPS-4240 and IPS-4255

---

Note IPS-4240 and the IPS-4255 do not support redundant power supplies.

---

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 replaces IDS-4235. There are four 10/100/1000 copper sensing interfaces. IPS-4240 is available with either AC or DC power. It monitors up to 250 Mbps of aggregate network traffic on multiple sensing interfaces and is inline ready. The 250-Mbps performance for IPS-4240 is based on the following conditions:

•2500 new TCP connections per second

•2500 HTTP transactions per second

•Average packet size of 445 bytes

•Running Cisco IPS 5.1 or later

---

Note The 250-Mbps performance is traffic combined from all four sensing interfaces.

---

IPS-4255 replaces IDS-4250-TX. There are four 10/100/1000 copper sensing interfaces. It monitors up to 600 Mbps of aggregate network traffic on multiple sensing interfaces and is also inline ready. The 600-Mbps performance for IPS-4255 is based on the following conditions:

•6000 new TCP connections per second

•6000 HTTP transactions per second

•Average packet size of 445 bytes

•Running Cisco IPS 5.1 or later

Connecting IPS-4240 to a Cisco 7200 Series Router

When an IPS-4240 is connected directly to a 7200 series router and both the IPS-4240 and the router interfaces are hard-coded to speed 100 with duplex Full, the connection does not work. If you set IPS-4240 to speed Auto and duplex Auto, it connects to the router but only at speed 100 and duplex Half.

To connect correctly at speed 100 and duplex Full, set the interfaces of both IPS-4240 and the router to speed Auto and duplex Auto. Also, if either interface is hard-coded, you must make the connection using a crossover cable.
