Cisco Catalyst 9120AXI-B Wi-Fi 6 access point

This indoor wireless access point supports the 802.11ax standard and delivers up to 5.38 Gbit/s across dual 2.40 GHz and 5 GHz bands. It includes a 2.5 Gigabit Ethernet uplink, a management port, USB 2.0, and internal antennas. The unit is powered via PoE and fits standard ceiling or wall mounts.

Ideal for offices needing Wi-Fi 6 density

Suits environments that require Bluetooth 5 support, a single 2.5 GbE uplink, and PoE-powered deployment. Not for buyers who need outdoor-rated hardware, multi-gig uplinks beyond 2.5 GbE, external antenna connectors, or controller-less operation without a Cisco DNA subscription.

5.38 Gbit/s maximum wireless throughput

The 5.38 Gbit/s peak rate defines the total radio capacity shared across both bands and all connected clients. Real-world throughput per device will be lower and depends on channel width, spatial streams, and RF conditions. Verify that your wired backbone and PoE budget can sustain the 2.5 GbE uplink before deploying at scale.

Questions about this item

Will the 2.5 GbE uplink on the C9120AXI-B saturate an older 1 GbE switch port?

The access point negotiates down to 1 GbE on legacy switches so it works without a port upgrade.

How can I confirm the Catalyst 9120 is delivering Wi-Fi 6 performance after installation?

Check the controller dashboard for 802.11ax client associations and throughput near the 5.38 Gbit/s PHY rate.

Does the C9120AXI-B ship with a PoE injector or must I buy one separately?

The factory-sealed box contains only the access point; a PoE+ injector or compatible switch must be purchased separately.
