AIR-AP1840I-I-K9C keeps the I regulatory-domain letter and K9C factory Mobility Express identity in its complete order code. Carry the complete I-domain PID through quotation, receiving, inventory, onboarding and replacement handling.
For I-domain K9C receiving, photograph the full label, verify the internal-antenna enclosure and capture the factory-image identity before configuration. Build a recovery sheet covering account access, management address, PoE, uplink, SSIDs, authentication and rollback rather than treating K9C as a cosmetic suffix.
For I-K9C receiving, preserve label photographs, internal-antenna confirmation, factory image identity and software entitlement before configuration. The handover file should then add management access, PoE negotiation, both uplinks, SSID behavior, rollback steps and the named person who accepted the result.
Receiving should hold the unit if the full I-K9C identity or factory-image evidence cannot be preserved. Cisco records the 1840 series as end of sale on May 1, 2022 and end of support on April 30, 2027.
