No new units, replacement parts, or Cisco TAC support exist any longer — refurbished, tested secondary-market units like ours are the only remaining source.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this include the cable I need to connect devices?\u003c\/strong\u003e\u003cbr\u003eNo, the CAB-HD8-ASYNC breakout cable is sold separately (we stock it too). The card has a single 68-pin port; the cable splits that into 8 individual RJ-45 serial connections.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this to build a terminal or console server for my lab or network?\u003c\/strong\u003e\u003cbr\u003eYes — this is the single most common use we see. Configure reverse Telnet or SSH on the router's async lines and each port becomes an independently addressable console connection, letting one router act as an 8-port console\/terminal server for switches, firewalls, PDUs, or other serial-console devices.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this work with non-Cisco equipment like UPS units, PDUs, or SCADA\/RTU gear?\u003c\/strong\u003e\u003cbr\u003eYes. The HWIC-8A provides plain EIA-232 async serial ports, so it works with any RS-232 device, not just Cisco hardware. Many customers use it as a lower-cost alternative to commercial serial-to-Ethernet device servers for exactly this reason.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this card DTE or DCE, and do I need a null-modem cable?\u003c\/strong\u003e\u003cbr\u003eThe HWIC-8A is DTE format only. If the device on the other end is also DTE (a server console port, many PDUs\/UPS units), you'll need a null-modem adapter between the two. If connecting to DCE equipment such as a modem, a straight-through connection is fine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many ports can one router support?\u003c\/strong\u003e\u003cbr\u003eMost ISR routers have two HWIC slots, so two HWIC-8A cards give you 16 async ports on a single router. You can also pair an HWIC-8A with an HWIC-16A for higher density.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between the HWIC-8A and the HWIC-8A\/S?\u003c\/strong\u003e\u003cbr\u003eThe plain HWIC-8A supports asynchronous EIA-232 in DTE format only. The HWIC-8A\/S (sometimes listed as HWIC-8A\/S-232) additionally supports synchronous connections and both DTE and DCE modes. If your project needs synchronous serial or DCE mode, make sure you're ordering the \/S variant, not this one.\u003c\/p\u003e\n\u003cp\u003eStill not sure if this is the right card for your setup? \u003cstrong\u003eContact us\u003c\/strong\u003e — we're happy to confirm compatibility before you buy.\u003c\/p\u003e","brand":"Cisco","offers":[{"title":"Default Title","offer_id":48070123815073,"sku":"HWIC-8A-R","price":1170.0,"currency_code":"BRL","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2216\/8673\/files\/Cisco-HWIC-8A-8-Port-Async-Serial-WAN-Interface-Card-Refurbished-Resilient-Tec.png?v=1791961848","url":"https:\/\/www.foxti.com.br\/products\/cisco-hwic-8a-8-port-async-serial-wan-interface-card-refurbished-resilient-tec","provider":"FoxTI","version":"1.0","type":"link"}
