Installing the IPS 4240 and the IPS 4255
Connecting the 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 the
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 the 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.
