AIR-AP1840I-D-K9C: Isolated K9C staging record

AIR-AP1840I-D-K9C keeps the D regulatory-domain letter and K9C factory Mobility Express identity in its complete order code. Preserve the D-domain quote, received label and enabled-channel evidence through controller migration.

For a D-domain Mobility Express unit, stage the factory image on an isolated management network, capture the initial controller role and then document whether it will remain the local controller or join another architecture. Record country selection, PoE source, both Ethernet links and representative clients before moving it to production.

Evidence required before acceptance

Save the purchase line, carton PID, serial label, configured domain, controller-role screenshot, management address, PoE source and the two switch ports. Add one successful authentication trace and one restore test. These records distinguish a correctly commissioned D-K9C unit from an enclosure that merely powers up.

Procurement decision

Purchase acceptance therefore depends on recoverable local management evidence as well as radio operation. Cisco records the 1840 series as end of sale on May 1, 2022 and end of support on April 30, 2027.
