Pre-Owned, Used And Refurbished Cisco HWIC-4A/S
The Cisco HWIC-4A/S is a Cisco High-Speed WAN Interface Card serial adapter with 4 low-seed synchronous/asynchronous ports and is one of five serial and asynchronous HWICs offered by industry-leader Cisco Systems. The HWIC-4A/S, along with the other four high-speed WAN interface cards, provides highly flexible connections for Cisco 1800, 2800, and 3800 series integrated services routers. It allows customers to enable applications such as WAN aggregation, console server, legacy protocol transport, and dial access server. Users may mix and match the HWIC-4A/Swith other HWICs to tailor cost-effective solutions for common networking problems like external dial-modem access, remote network management, low-density WAN aggregation, high port density support, and legacy protocol transport. This interface card uses a Smart Serial connector.
Our extensive HWIC-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 HWIC-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 HWIC-4A/S purchase with our standard one year warranty. All used HWIC-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 HWIC-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.
