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 SM-X-24FXS/4FXO-RF TAA compliant and available for government and DoD buyers?
It depends on the unit. Cisco manufactures the SM-X-24FXS/4FXO-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 SM-X-24FXS/4FXO-RF and a specialist will confirm the TAA option, price, and lead time, usually within one business day.
Can I buy the SM-X-24FXS/4FXO-RF as a single unit or in volume?
Both. Order a single SM-X-24FXS/4FXO-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 SM-X-24FXS/4FXO-RF datasheet and specifications?
The SM-X-24FXS/4FXO-RF datasheet is on this page: open the gated document for the full PDF. The specifications section also lists ports, power, and dimensions where Cisco publishes them.
Need the SM-X-24FXS/4FXO-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 →
