This item is composed of a 2811 Router + an NM-16A Module. It also includes 1 x Octal Cable. The 2811 Router is loaded with IOS 15.1
A Terminal Server based on a Cisco 2800 with an NM-16A module offers several advantages over the more traditional 2511 Terminal Server:
- First of all, it doesn't require an AUI adapter.
- Second, it is more reliable, mainly because the 2511 is an old device (not made anymore).
- And third, it supports SSH!
The MTTF (Mean Time To Failure) of a 2600 with a NM-16A is far greater than a traditional 2511/2511-RJ Terminal Server. In simple words, it is much more reliable!
In addition, 2800 Routers support SSH, which is NOT supported under any Cisco 2500 Router, because the 2500's do not support Crypto commands!
