Frequently asked questions
How much does the Cisco 4-Port Async/Sync Serial HWIC - 4 x Asynchronous/Synchronous Serial (HWIC-4A/S-RF) cost?
Uniqcli sells the HWIC-4A/S-RF for $833.12 against a Cisco list price of $1,025.10. Add it to your cart and submit to confirm current pricing, stock, and lead time. Lower pricing is available for volume orders, Government Purchase Card (GPC) buys, and emergency or urgent acquisitions. Free US shipping on orders over $2,500.00.
Is the HWIC-4A/S-RF TAA compliant and available for government and DoD buyers?
It depends on the unit. Cisco manufactures the HWIC-4A/S-RF in several countries, so Trade Agreements Act (TAA) status is decided per part number and production lot. Uniqcli is an authorized Cisco partner: where Cisco offers a TAA-designated version (usually a ++ part number) we quote that, we confirm the country of origin before shipment, and we attach a country-of-origin statement on request. That is how US federal, DoD, state, local, education, and healthcare buyers get an audit-ready file, with Government Purchase Card (GPC) acceptance and FAR-based urgent and emergency acquisition support. Request a TAA-compliant quote for the HWIC-4A/S-RF and a specialist will confirm the TAA option, price, and lead time, usually within one business day.
Can I buy the HWIC-4A/S-RF as a single unit or in volume?
Both. Order a single HWIC-4A/S-RF through the cart, or ask about lower pricing for volume orders, Government Purchase Card (GPC) purchases, and emergency or urgent (FAR-based) acquisitions. There is no payment up front: we confirm availability and the final total before invoicing.
Where can I find the HWIC-4A/S-RF datasheet and specifications?
The specifications section on this page lists the published specs for the HWIC-4A/S-RF, including ports, power, and dimensions where Cisco publishes them. Ask us for the full Cisco datasheet and we will send the current PDF with your quote.
Need the HWIC-4A/S-RF TAA-compliant for federal or DoD?
Cisco builds this model in multiple countries, so TAA status is decided per part number and production lot. Where Cisco offers a TAA-designated version (usually a ++ part number) we quote that, confirm the country of origin before shipment, and attach the paperwork. GPC-payable. Check the TAA line →
