Cisco HWIC-8A 8-Port Async Serial WAN Interface Card - Refurbished | Resilient Tec
Warranty: Lifetime
Cisco HWIC-8A — 8-Port Asynchronous Serial WAN Interface Card | Refurbished & Tested
The Cisco HWIC-8A is an 8-port asynchronous serial WAN interface card that slots into the HWIC bay of compatible Cisco Integrated Services Routers (ISR). It adds eight EIA-232 async serial ports for terminal server deployments, out-of-band management networks, and console aggregation — the same card Cisco ships new, at a fraction of the cost. Every unit is fully tested and confirmed functional before shipment. 22 units in stock, ships same day.
Which Cisco Routers Does the HWIC-8A Fit?
The HWIC-8A is compatible with any Cisco ISR that has an available HWIC expansion slot:
- Cisco ISR 1800 series (1841, 1861 and compatible)
- Cisco ISR 2800 series (2801, 2811, 2821, 2851)
- Cisco ISR 3800 series (3825, 3845)
- Cisco ISR G2 2900 / 3900 series — verify slot type before ordering

Refurbished vs New — What You Actually Get
| Feature | Refurbished (This) | New OEM |
|---|---|---|
| Functionality | ✅ Fully tested, 100% operational | ✅ Fully operational |
| Cost | ✅ Significantly lower | 2-4x higher |
| Availability | ✅ In stock now (22 units) | Often EOL / long lead time |
| Warranty | ✅ Lifetime warranty (Resilient Tec) | Standard Cisco warranty |
| Best for | ✅ Lab, enterprise, OOB networks | New greenfield deployments |
Note: the HWIC-8A is an end-of-life Cisco product. Refurbished is now the only reliable source — and our units are tested before every shipment.
Ideal Use Cases
- Terminal server deployments — connect up to 8 serial devices for centralized out-of-band console access
- Out-of-band (OOB) management networks — maintain router/switch/firewall access when in-band paths fail
- Enterprise and data center console aggregation — reduce the number of console cables and access points
- Lab and training environments — CCNA, CCNP, CCIE racks requiring async serial console access
- ISR expansion — add serial WAN or async management capability to an existing ISR deployment
What Cable Do You Need?
The HWIC-8A uses a 68-pin HD D-Sub connector on the card. To connect to serial devices, you need the Cisco CAB-HD8-ASYNC breakout cable — this cable is sold separately and breaks out the single 68-pin port into 8 x RJ-45 connections. We stock this cable as well.
