19 C H A P T E R Connecting Content Engine Network Modules for Caching and Content Delivery This chapter describes how to connect content engine (CE) network modules for caching and content delivery and contains the following sections: • CE Network Modules, page 19-1 • CE Network Module LEDs, page 19-4 • Online Insertion and Removal with a CE Network Module, page 19-5 • Related Documents, page 19-7 Tip To determine whether your router supports a specific network module, see Table 1-6 on page 1-16. CE Network Modules This section provides overview information on CE network modules. The following CE network modules are available on Cisco modular routers: • CE network module with a 40-GB Disk Expansion Module (NM-CE-BP-40G-K9) (see Figure 19-1) • CE network module with a 80-GB Disk Expansion Module (NM-CE-BP-80G-K9) (see Figure 19-1) • CE network module with a SCSI Controller Expansion Module and a 68-pin SCSI connector for connection to an external storage array (NM-CE-BP-SCSI-K9) (see Figure 19-2) The 80-GB CE network module can run Application and Content Networking System (ACNS) software or Cisco Wide Area File Services (WAFS) software. The 40-GB CE network module and the CE network module with a SCSI controller can run ACNS software only. For information on configuring ACNS or WAFS, see the documentation listed in the "Related Documents" section on page 19-7. Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the CE network modules (NM-CE-BP-40G-K9 and NM-CE-BP-80G-K9) only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends. OL-2485-20 Cisco Network Modules Hardware Installation Guide 19-1
