C9117AXI-EWC-D retains the D suffix and EWC embedded-controller boundary in its exact PID. Preserve D-domain quote, label and controller configuration as one traceable commissioning record.
The D-domain EWC acceptance should compare the approved RF survey with actual internal-antenna placement, channel behavior and client results. Separately test embedded management backup and recovery, then link both evidence sets to the same installed serial.
Retain D-domain authorization, mounting position, MAC address, configured country, PoE source, 2.5GbE link, controller role and backup location. Record measurements at named survey points so later replacement tests use the same method.
A successful controller login does not close the D-EWC order until placement and survey evidence also pass. Cisco lists April 30, 2021 as end of sale and April 30, 2026 as the last date of support.
