AIR-AP1840I-G-K9C keeps the G regulatory-domain letter and K9C factory Mobility Express identity in its complete order code. Attach the G-domain approval to the asset record and compare it again after firmware or country-setting changes.
The G-domain Mobility Express record should identify which AP owns the controller function, where backups are stored and who can recover the site without vendor defaults. Compare channel behavior and client authentication before and after upgrades, and repeat the regulatory check if the physical destination changes.
Document which G-K9C access point owns site management, how another administrator reaches the backup and what must be restored after replacement. Save channel, authentication and representative client evidence before and after the recovery exercise, plus the approval used for the installed destination.
A replacement is acceptable only when management recovery and destination authorization remain traceable. Cisco records the 1840 series as end of sale on May 1, 2022 and end of support on April 30, 2027.
