The HWIC-8A is a reliable card for our serial connections. It provides solid performance and integrates easily with our Cisco router.
This card is perfect for expanding our serial network. The HWIC-8A is fast, reliable, and easy to set up.
The HWIC-8A offers great performance for serial communication. It's been easy to install and has significantly improved our network setup.
We've had great results with the HWIC-8A. It's a reliable, high-performance card that provides solid serial connectivity for our network.
The HWIC-8A has been a great addition to our network. It provides solid performance and reliable serial communication across our systems.
The HWIC-8A is an 8-port asynchronous high-speed WAN interface card designed for Cisco ISR routers, enabling simultaneous dial-up connectivity across eight serial interfaces.
The HWIC-8A is compatible with Cisco 1800, 2800, and 3800 ISR series routers that feature a High-Speed WAN Interface Card slot.
Each asynchronous port on the HWIC-8A supports data rates up to 2.1 Mbps, accommodating legacy modem, fax, and remote access applications.
The HWIC-8A supports PPP, PAP, CHAP, MLPPP, Frame Relay, and HDLC encapsulation protocols over asynchronous serial ports.
Power down the router, insert the HWIC-8A into an available HWIC slot, secure the card with the retention screw, and power up to auto-detect the module.
Use global configuration mode with commands like `interface async0/0` through `interface async0/7`, then assign IP addresses and encapsulation with `ip address` and `encapsulation` commands.
No additional software license is required; the HWIC-8A is enabled under standard Cisco IOS for supported router platforms.
The HWIC-8A functions as a DTE interface; external DCE devices or modems must supply clocking for synchronous connections.
Typical use cases include telemetry, legacy dial-up modems, fax servers, remote branch dial-in access, and out-of-band management.
The HWIC-8A supports up to eight concurrent asynchronous sessions, one per physical port.
The HWIC-8A consumes approximately 3.5 W under typical load conditions, ensuring minimal impact on router power budgets.
The module measures 10.2 cm × 10.8 cm × 1.6 cm and weighs approximately 0.2 kg, matching Cisco HWIC slot form factors.
Unlike a standard WIC with one or two ports, the HWIC-8A offers eight asynchronous ports in a single HWIC slot, maximizing port density.
Yes. The HWIC-8A is supported in Cisco packet-level simulation tools like Cisco Packet Tracer and VIRL for functionality testing.
Cisco provides a limited lifetime warranty on the HWIC-8A with access to software updates and Cisco Technical Assistance Center support.
You can purchase or reorder the HWIC-8A through authorized Cisco resellers or the Cisco Commerce portal using SKU HWIC-8A.
