CE Network Modules
The NM-CE-BP network module clock may be reset to 1980 if it is powered off for a long period. Several
Note
applications that depend on correct time being configured on the network module may not work in such
a scenario. Therefore we strongly recommended that the NM-CE-BP network module be configured for
NTP using the ntp server server Cisco IOS command, either after a software upgrade from Application
and Content Networking System software Release 4.2.x to Release 5.x, or on obtaining a new network
module, to maintain correct time on the network module.
There is no backup power for a network module's real time clock. Once power has been turned off or the
Note
network module has been removed from the router, the real time clock stops.

Note Some early CE network modules have an inactive USB port on the faceplate. This USB port has been
removed in later Cisco CE network modules.

Connecting CE Network Modules to the Network
To connect a CE network module to the network, from the RJ-45 port on the CE network module use a
straight-through two-pair Category 5 unshielded twisted-pair (UTP) cable to connect to a switch, hub,
repeater, server, or other network device. (See
