Pre-Owned, Used And Refurbished Cisco NM-4A/S

Cisco's NM-4A/S is one of the most versatile serial connections that Cisco offers. This 4-port interface supports a wide variety of protocols and applications, including WAN concentration, transport of SDLC and Bi-sync data, and asynchronous terminal connections. The NM-4A/S interface supports a maximum synchronous speed of 128 Kbps, and a maximum asynchronous speed of 115.2 Kbps. Then NM-4A/S, like the NM-8A/S, uses the 60-pin "5-in-1" cables, similar to those used on the Cisco 2500 and Cisco 7000 series routers.

Our extensive NM-4A/S inventory provides for quick order turn-around, often allowing us to ship "same day" or within just 1-2 business days. What's more? As an independent supplier, we are able to offer more equipment options than are available through distribution, including new, used and refurbished NM-4A/S. In some instances, our pre-owned equipment may still be in new condition, still sealed in original factory packaging (but at a fraction of the cost).

MLCP is committed to quality, and we guaranty any refurbished Cisco NM-4A/S purchase with our standard lifetime warranty. All used NM-4A/S equipment is tested to factory specifications and packaged professionally for safe transport. As an experienced supplier of pre-owned network hardware, we understand that we have to be better than the manufacturer, and that fundamental principle guides us every day.

Is your interest in the NM-4A/S as a result of an upgrade? We may be interested in your surplus networking equipment and encourage you to take advantage of our flexible "buy-back" options, including an up-front purchase option and generous trade-ins for credit.
