Chapter 34 Connecting Cisco Network Admission Control Network Modules Connecting NAC Network Modules Shutting Down the NAC Network Module Press the shutdown button on the network module faceplate for less than 2 seconds to perform a graceful shutdown of the hard disk before removing power from the router or before starting an online insertion and removal (OIR) sequence on the router. The application may take up to 2 minutes to fully shut down. Note See the Getting Started with NAC Network Modules in Cisco Access Routers document on Cisco.com for instructions that describe how to shut down the network module from the command line interface on the router, http://www.cisco.com/en/US/products/ps6128/prod_installation_guides_list.html Caution If you press the shutdown button for more than 4 seconds, a non-graceful shutdown of the hard disk will occur and may cause file corruption on the network module's hard disk. After a non-graceful shutdown, the DISK and SYS LEDs remain lighted. Press the shutdown button for less than 1 second to gracefully reboot the network module. Connecting NAC Network Modules To connect Cisco NAC network modules to an external device use a straight-through two-pair Category 5 unshielded twisted-pair (UTP) cable and connect the RJ-45 Gigabit Ethernet port on the network module to a switch, hub, repeater, or other Gigabit Ethernet network device. Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Network Admission Control Network Modules (NME-NAC-K9) only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring. Note RJ-45 cables are not available from Cisco Systems. These cables are widely available and must be Category 5 cables. OL-2485-20 Cisco Network Modules Hardware Installation Guide 34-23
