CE Network Modules Chapter 19 Connecting Content Engine Network Modules for Caching and Content Delivery Note The NM-CE-BP network module clock may be reset to 1980 if it is powered off for a long period. Several 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. Note There is no backup power for a network module's real time clock. Once power has been turned off or the network module has been removed from the router, the real time clock stops. Figure 19-1 Faceplate for the CE Network Module with 40- or 80-GB Disk Expansion Module NM-CE-BP DISK LINK ACT PWR EN FastEthernet 0 CF 72090 Figure 19-2 Faceplate for the CE Network Module with SCSI Connector Expansion Module NM-CE-BP DISK LINK ACT PWR EN FastEthernet 0 CF 72089 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. Tip For information on removing, replacing, and installing the expansion modules, see the Installing Expansion Modules on Cisco CE Network Modules for Caching and Content Delivery document. 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.
