C9115AXI-EWC-D - Cisco Catalyst 9115 WiFi 6 Dual-band Access Point

C9115AXI-EWC-D exact order identity

C9115AXI-EWC-D is a Cisco Catalyst 9115 Series indoor 802.11ax access point. The complete PID selects the I antenna form, access-point order carrying an Embedded Wireless Controller image and regulatory-domain token D.

Antenna and installation boundary

Cisco documents integrated omnidirectional antennas with peak gain of 3 dBi at 2.4 GHz and 4 dBi at 5 GHz. External antennas are not part of this AXI order. Mounting position, enclosure orientation and measured RF coverage are the installation evidence.

Controller-image boundary

Cisco defines the EWC order as a Catalyst 9115 access point supplied with the Embedded Wireless Controller software image. Cisco ended sale of EWC-AP orders on 2024-11-29, names IOS XE 17.15.x as the final EWC-AP train and permits conversion to lightweight CAPWAP mode.

D regulatory evidence

Cisco treats the final token as a regulatory-domain identifier and makes the customer responsible for verifying country approval. For a D-domain spare, record the approved protected sites so it cannot be moved to a destination with a different domain requirement.

Treat this D-domain unit as location-controlled inventory. Name the destination or protected spare population, record who may reassign it and require a new Cisco lookup before any transfer. Commissioning should retain the controller country and enabled-channel outputs. This prevents an unused spare from appearing technically interchangeable after organizational or geographic changes.

PoE and environmental reduced states

With 802.3at, the 9115 operates both radios at 4x4, negotiates 2.5G and enables USB; 802.3at full-feature consumption is published as 20.4W. Under 802.3af both radios reduce to 2x2, Ethernet reduces to 1G and USB is disabled. Cisco also documents the same reduced state above 40 degrees C ambient.

Lifecycle and migration decision

The EWC order has already passed its 2024-11-29 end-of-sale date. Cisco identifies 17.15.x as the final EWC-AP train and 2029-11-30 as last support, while allowing conversion to lightweight CAPWAP mode.

Deployment evidence worksheet

Controller join evidence

Stage the access point on the controller release intended for production. Retain the controller model, software version, discovery path, authorization method and first successful CAPWAP join. Confirm that configuration download completes and that both radios reach an expected operational state. Remove any temporary staging authorization before handover. This evidence separates an orderable access point from a unit that has actually been proven compatible with the planned controller environment. For this 9115 order, retain controller discovery, image transfer and final join beside the exact serial.

Ethernet and cabling proof

Preserve the permanent-link test, patch-lead identities, switch port, negotiated Ethernet rate and error counters. Investigate pair faults, excessive length or rate fallback before wireless acceptance begins. A link light only proves connectivity at some rate; it does not demonstrate the intended uplink performance. Tie the cable result to the AP serial so a later throughput problem can be separated from radio, controller and wired-path causes. Confirm 2.5-Gigabit negotiation under full power and retain switch-port counters with the acceptance result.

Survey-to-install reconciliation

Attach the approved RF survey location, mounting height, orientation, expected client density, channel width and neighboring-radio assumptions to the order. After installation, compare measured coverage and interference with that design. If ceiling construction, antenna placement or obstructions changed, document the deviation and repeat the affected measurements. This provides a site-specific acceptance reason for the exact unit instead of relying on a family data sheet alone. Tie the accepted RF survey to the exact integrated or external antenna form shown by the PID.

Quotation substitution gate

Compare antenna form, regulatory token, configuration suffix, pack quantity and complete Cisco part number on the authorized quotation. Treat any changed token as a substitution that requires a new technical and regulatory review. Procurement should not accept a nearby Catalyst 9115 line merely because the family name matches. Preserve the approved line, received label and exception decision so the final asset can be traced to the exact order reviewed here. Treat a changed antenna letter, EWC infix or regulatory token as a new procurement identity.

Software lifecycle file

Record the controller release approved for this unit, the source used to verify support, the last tested date and the owner for software advisories. Available hardware does not prove compatibility with a current or future controller train. Review Cisco support information before every expansion or replacement. The lifecycle file should also state when this Catalyst 9115 generation must leave service and which surrounding dependencies need migration. Apply the published hardware or EWC lifecycle to support and migration planning instead of inventory age.

Capacity observation

Define the expected concurrent clients, application mix, airtime utilization and channel-width assumptions for this location. After commissioning, capture radio utilization, retry behavior and representative throughput during a meaningful load period. Compare the observation with the survey design and state any shortfall. A peak link rate from a data sheet is not a site capacity result and should not replace measured operating evidence. Use measured airtime, retries and client performance rather than the family's maximum PHY rate.

Receiving inspection

At receipt, compare model label, regulatory token, antenna form, quantity, serials and visible condition with the authorized order. Photograph labels before cartons are separated. Quarantine shortages, mixed units, damaged connectors or unapproved substitutions. Do not rely on a distributor description as evidence that the exact Cisco order arrived. Close the inspection only when every physical unit is accounted for. Receiving must distinguish AXI from AXE and EWC from non-EWC before the chassis is powered.

Operational log retention

Store the initial controller events, switch-port state, radio assignment, channel list and client test results with a consistent asset identifier. Define how long commissioning evidence is retained and who can retrieve it. A later firmware, controller or RF change should add a new dated observation rather than overwrite the original. The resulting history supports lifecycle decisions and distinguishes a new regression from the accepted baseline. Keep the first accepted power, wired, radio and client results as the baseline for later troubleshooting.
