Power Source Not Included
The HPE Networking Instant On R9B27A is a dual-band Wi-Fi 6 indoor access point built for small offices, clinics and retail spaces that need high-density coverage. It delivers 4x4 MIMO on the 5 GHz radio for up to 4.8 Gbps and 2x2 MIMO on the 2.4 GHz radio for up to 574 Mbps. A 2.5 Gigabit Ethernet uplink with PoE-in support connects the unit to the wired network.
The AP includes a mounting bracket for ceiling or wall installation and a Kensington security slot for physical locking. Power comes from an 802.3at PoE switch or injector (up to 20.1 W) or a separate 12 V DC adapter (15.9 W); neither is included unless a bundle SKU is purchased. A reset button and LED status indicators simplify initial setup and troubleshooting.
Ensure your PoE switch or injector provides 802.3at class 4 power and that the 2.5 GbE uplink matches your switch ports. This is the US regulatory domain model; it cannot be used in regions requiring a different country code. Confirm the ceiling or wall material can support the 2.6 lb unit and that the down-tilt antenna pattern suits the room layout.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
Check the Instant On dashboard for client link speeds showing 160 MHz channel width and 4x4 MIMO on the 5 GHz radio; the LED status indicators will display solid green when the 2.5 Gigabit Ethernet uplink is active and PoE-in is supplying up to 20.1 W.
The box contains the AP25 unit with down-tilt omni-directional antennas, a Kensington security slot, reset/LED control button and Bluetooth Low Energy radio; power sources are sold separately unless you buy the bundle SKU, so you need an 802.3at PoE injector or a 12 V DC adapter.
The single R9B27A model meets EN 60601-1-1 and EN 60601-1-2 for medical environments and provides 2.4 GHz 802.11ax 2x2 MIMO up to 574 Mbps alongside the 5 GHz 4x4 radio, so no higher-capacity version is required.
