Questions & Answers
What is the AR-8SA-W 8-Port Sync/Async Serial WAN Interface Card?
The AR-8SA-W is an 8-port serial WAN interface card that delivers configurable synchronous and asynchronous connections for enterprise-grade router deployment.
Which serial interfaces are supported by the AR-8SA-W?
The AR-8SA-W supports V.35, X.21, RS-232, RS-449, and RS-530 interfaces for broad network compatibility.
What data rates can the AR-8SA-W achieve?
Each port supports data rates from 50 bps to 2 Mbps, accommodating a wide range of serial WAN link speeds.
Can I mix synchronous and asynchronous ports on the AR-8SA-W?
Yes. You can independently configure each of the eight ports as synchronous or asynchronous to match your application requirements.
Which routers are compatible with the AR-8SA-W?
The AR-8SA-W is compatible with the AR-2600, AR-3600, and AR-6000 router series, as documented in the hardware installation guide.
How do I install the AR-8SA-W in my router?
Power off your router, insert the AR-8SA-W into an available expansion slot, secure it with screws, and power the router back on. The device is automatically detected on boot.
Does the AR-8SA-W support CSU/DSU bypass?
Yes. The card features integrated CSU/DSU bypass on each port, ensuring continuous link uptime in case of device failure.
What WAN protocols does the AR-8SA-W support?
It natively supports PPP, HDLC, Frame Relay, X.25, and LAPB protocols for versatile WAN connectivity.
How do I configure an AR-8SA-W port on my router’s operating system?
Use the CLI to enter interface configuration mode (e.g., interface serial x/y), set encapsulation, clock rate, and port type, then save the configuration.
Is the AR-8SA-W hot-swappable?
No. The AR-8SA-W must be installed or removed only when the router is powered off to prevent hardware damage.
What are the power and thermal requirements for the AR-8SA-W?
The card consumes up to 10 W and requires an ambient operating temperature of 0 °C to 40 °C, as specified in the router’s environmental guidelines.
How does the AR-8SA-W improve network performance?
By offloading serial processing to dedicated hardware, the AR-8SA-W increases throughput, reduces latency, and maintains QoS across WAN links.
Where can I purchase compatible cables for the AR-8SA-W?
You can order factory-tested V.35, X.21, and RS-232 cables from authorized resellers or through our online store using part numbers listed in the card’s datasheet.
What warranty covers the AR-8SA-W?
The AR-8SA-W is covered by a limited lifetime hardware warranty, including next-business-day advance replacement for eligible customers.
How many channels can I run simultaneously on the AR-8SA-W?
You can run up to eight independent channels concurrently, each with its own clocking and encapsulation settings.
How do I verify the AR-8SA-W status after installation?
Use the router CLI command show hw-module slot x brief to confirm module presence, and show controllers serial x/y to view port status and statistics.
