AIR-AP1840I-Z-K9: Installed-asset custody trail

AIR-AP1840I-Z-K9 keeps the Z regulatory-domain letter and K9 controller-based identity in its complete order code. Use the Z-domain suffix as a controlled ordering identity, not as a country name inferred by this page.

The Z-domain controller-based order needs a full custody trail from authorized quote to installed serial. Keep controller addresses, DHCP option behavior, country setting, mounting position and acceptance measurements together. Reassignment to another country or controller creates a new review event rather than overwriting the original evidence.

Evidence required before acceptance

The Z-K9 custody file should retain the authorized quote, received serial, controller addresses, discovery behavior, configured country, mounting point and acceptance measurements. A move to another destination or controller opens a new review; it must not overwrite the evidence that justified the original installation.

Procurement decision

The Z-K9 suffix remains part of the controlled asset identity throughout its installed life. Cisco records the 1840 series as end of sale on May 1, 2022 and end of support on April 30, 2027.
