Pre-owned, used and refurbished Juniper NS-ISG-1000B-DC

At MULTI-LINK (MLCP), you will find a wide range of security products, including the Juniper NS-ISG-1000B-DC. We offer new, used and refurbished security products across all model lines.

Whether your specific need is for one NS-ISG-1000B-DC or a significant quantity - for a complete security configuration or an individual insert component - MLCP's mission is to help meet your requirement quickly. However, no matter how large our own physical NS-ISG-1000B-DC inventory, we can not always fulfill customer orders from stock, and so we also rely on our immediate access to an international pool of secondary market resources. Whatever it takes to fulfill your pressing requirements, MULTI-LINK has the resources to get it done.

Used and pre-owned NS-ISG-1000B-DC, as well as other used Juniper security products, are tested to meet factory specifications at our Torrance, CA headquarters. Your NS-ISG-1000B-DC is guaranteed with our one year warranty, standard for all refurbished Juniper equipment sold by MULTI-LINK.

Do you have surplus NS-ISG-1000B-DC or other security products you'd like to turn-in? If so, MULTI-LINK may be interested in your equipment, and we offer a variety of flexible buy-back options to help you get the most out of your surplus equipment. We'll make it easy, too, arranging for pick-up and transport from your facility to ours.

Whether you are looking to buy or sell, please contact a sales representative at 1-800 TO MULTI (866-8584) for assistance.
