| WI-FI ANTENNAS |
| Antenna |
Integrated downtilt omni-directional antennas for 4x4 MIMO in 2.4GHz with peak antenna gain of 4.3dBi, and 8x8 MIMO in 5GHz with peak antenna gain of 5.8dBi in 5GHz. In tri-radio mode, the peak gain of the antennas for each of the 4x4 5GHz radios is 5.5dBi (radio 0L, lower half of 5GHz) and 5.6dBi (radio 0U, upper half of 5GHz). Built-in antennas are optimized for horizontal ceiling mounted orientation of the AP. The downtilt angle for maximum gain is roughly 30 degrees.
- A mix of horizontally and vertically polarized antenna elements is used
- Combining the patterns of each of the antennas of the MIMO radios, the peak gain of the combined, average pattern is 2.4dBi in 2.4GHz and 2.0dBi in 5GHz (dual-radio mode).
- In tri-radio mode, the peak gain of the combined, average pattern is 2.7dBi (radio 0L, lower half of 5GHz) and 1.8dBi (radio 0U, upper half of 5GHz) |
| OTHER INTERFACES |
| Interfaces |
E0, E1: HPE SmartRate port (RJ-45, maximum negotiated speed 5Gbps)
- Auto-sensing link speed (100/1000/2500/5000BASE-T) and MDI/MDX
- 2.5Gbps and 5Gbps speeds comply with NBase-T and 802.3bz specifications

managed traffic forwarding and segmentation, data encryption, and policy enforcement. |
| Management options |
Aruba Central (cloud-managed) or Aruba AirWave |
| POWER SOURCES AND POWER CONSUMPTION |
Power Sources: The AP supports
direct DC power and Power over
Ethernet |
- The AP supports direct DC power and Power over Ethernet (POE; on port E0 and/or E1)
- When POE power is supplied to both Ethernet ports, the AP can be configured to combine or prioritize power sources
- When both DC and POE power sources are available, DC power takes priority over POE
- Power sources are sold separately; see the ordering Information section below for details
- When powered by DC, 802.3bt (class 5) POE or 2x 802.3at (class 4) POE, the AP will operate without restrictions.
- When powered by 1x 802.3at (class 4) POE and with the IPM feature disabled, the AP will disable the USB port, disable the other Ethernet port, operate the 5GHz radio in 4x4 mode, and disable tri-radio operation
- In the same configuration but with IPM enabled, the AP will start up in unrestricted mode, but may dynamically apply restrictions depending on the POE budget and actual power. The feature restrictions and order can be programmed.
- Operating the AP with an 802.3af (class 3 or lower) POE source is not supported.
|
Maximum (worst-case) power
consumption (without / with a USB
device attached): |
- DC powered: 32.6W
- POE powered (802.3bt or dual 802.3at): 38.2W
- POE powered (802.3at, IPM disabled): 25.1W
- All numbers above are without an external USB device connected. When sourcing the full 5W power budget to such a device, the incremental (worst-case) power consumption for the AP is up to 6.0W (POE powered) or 5.4W (DC powered) |
Maximum (worst-case) power
consumption in idle mode: |
15.0W (POE) or 15.1W (DC) |
Maximum (worst-case) power
consumption in deep-sleep mode: |
3.8W (POE) or 3.6W (DC) |
