(See the "Installing Cisco Network Modules in Cisco Access Routers" section on page 2-5.) Connecting Cisco High-Density Extension Modules to the Network The Cisco high-density extension module is connected to a distribution frame or patch panel with an RJ-21 cable. (See Figure 28-4.) RJ-21 cables are not provided with the network module. Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001 Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the 8-port analog voice/fax expansion module (EM-HDA-8FXS) and 4-port digital voice/fax expansion module (EM-4BRI-NT/TE) only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends. For ordering information, see the "Obtaining Technical Assistance" section on page xi. 28-6 Cisco Network Modules Hardware Installation Guide OL-2485-20
