Pre-owned, used and refurbished Cisco NM-1A-OC3MM

Purchase quality Cisco router equipment at the industry's best prices, including the NM-1A-OC3MM. MULTI-LINK (MLCP) carries an extensive inventory of new, refurbished and used Cisco router equipment across all product series, so we can assist with everything from SOHO to core router requirements.

Our extensive NM-1A-OC3MM 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-1A-OC3MM. 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-1A-OC3MM purchase with our standard one year warranty. All used NM-1A-OC3MM 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-1A-OC3MM 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.
