NIM-16A is the Cisco 16-port asynchronous serial network interface module for the 4000 Series Integrated Services Routers, designed specifically for terminal-server use. It does not support SLIP or PPP. The 24-port version is NIM-24A, and the 64-port service module is SM-X-64A.
Sixteen RS-232 ports come out through two 8-port sockets, upper and lower, and each accepts a CAB-HD8-ASYNC or CAB-ASYNC-8 cable. The middle socket is not used on the NIM-16A. A speed of 9600 baud is recommended, 115200 baud suits only a few simultaneous connections, and 230400 baud is not recommended.
It works in the Cisco 4221, 4321, 4331, 4351, 4431 and 4451 routers. The maximum number of modules is 2 in the 4221 and 4321, 2 in the 4331 (3 with an SM-X-NIM-ADPTR adapter), 3 in the 4351 and 4451 (5 with adapters) and 3 in the 4431.
The router needs Cisco IOS XE Release 16.3.1 or later with the IP Base feature set or higher. The module measures 1.25 x 3.5 x 6.7 inches (32 x 89 x 172 mm).
