NME-NAC-K9 Cisco Network Admission Control (NAC) Network Module

The NME-NAC-K9 is a Cisco Network Admission Control (NAC) network module. Network administrators use it to authenticate, authorize, evaluate and remediate wired, wireless and remote users and their machines before those users reach the network. It checks laptops, desktops and corporate assets for compliance with the network's security policies and addresses vulnerabilities before access is permitted.

Hardware preinstalled at the factory is an 80 GB hard disk, 512 MB of memory and 64 MB of CompactFlash. A single RJ-45 Gigabit Ethernet port connects to a switch, hub, repeater or other Gigabit Ethernet device over a straight-through two-pair Category 5 UTP cable. LEDs are CF, LINK, ACT, DISK, PWR/SYS and EN.

Unlike other network modules, it uses a hard disk. Pressing the faceplate shutdown button for less than 2 seconds starts a graceful shutdown that can take up to 2 minutes, and holding it for more than 4 seconds forces a non-graceful shutdown that can corrupt files. Cisco supports the module on the CISCO2811 router, Cisco 2821, Cisco 2851 and Cisco 3800 series routers, including the CISCO3825 router. More options are in Cisco routers.
