For Cisco 2691, Cisco 3725, and Cisco 3745 routers only, ensure that the ROM monitor 
(ROMMON) version is 12.2(8r)T2 or a later version. This ROMMON version contains a fix that 
prevents the router from resetting all the network modules when it is reloaded. 

Cisco IOS Release 12.2(11)YT, Cisco IOS Release 12.2(13)T, or a later release is required.

Cisco ACNS software Version 4.2.3 or a later release is required.

The only ACNS software features supported by the CE network module are the ACNS software 
content engine features.

Online insertion and removal (OIR) is supported only on Cisco 3660 and Cisco 3745 platforms.

Transmission speed over the internal CE link is automatically negotiated between the CE interface 
and the Cisco IOS interface on the router side. On Cisco 2600 series and Cisco 2600XM series 
platforms except for the Cisco 2691, a speed of 10 Mbps is negotiated. On all other platforms, the 
speed of 100 Mbps is automatically negotiated.

The maximum number of CE network modules that can be installed in a router is limited by the 
amount and type of power that is provided to the network module slots.
