Front and Back Panel Features Chapter 2 Installing the IPS 4240 and the IPS 4255 The IPS 4255 replaces the 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 the 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 Note The 600-Mbps performance is traffic combined from all four sensing interfaces. Front and Back Panel Features Note Although the illustrations show the IPS 4240, the IPS 4255 has the same front and back panel features and indicators. This section describes the IPS 4240 and the IPS 4255 front and back panel features and indicators. Figure 2-1 shows the front view of the IPS 4240 and the IPS 4255.
