HUAWEI AirEngine 6761-21E AirEngine 6700 Series Access Points

• Wall
• Ceiling (Solid Wall/Gypsum Board/Spring Tee/Flat-Edge T-Rail/Channel Rail/Beam/Threaded Rod)
• Junction Box (86 mm/1-Gang 120 mm/Octagonal/2-Gang 120 mm)

• PoE
• DC power adapter

DC: 42.5 V to 57 V

PoE: 802.3at/af

PoE port:

Differential mode (48 V-RTN): 0.5 kV (1.2/50 us, 42 ohms), criterion B

Common mode (8 wires to ground): 6 kV (1.2/50 us, 42 ohms), criterion B

No priorities are distinguished for the following power supply modes: DC power supply, PoE power supply over an Ethernet cable, and PoE power supply over a hybrid cable, which do not support hot backup.

Either of the electrical port or the SFP+ hybrid port can be used for PoE input, but not both.

2.5GE (RJ45) x 1, 10M/100M/1000M/2.5GE auto-sensing

10GE (SFP+) x 1, 1000M/10GE auto-sensing

Either the 2.5GE electrical port or SFP+ optical port can be used for data communication at the same time. If both ports are used, the optical port is preferentially for communication.

• 2.4GHz
• 5GHz

Radio 0 (2.4 GHz): 4x4

Radio 1 (5 GHz): 4x4

2.4 GHz: 802.11b/g/n/ax

5 GHz: 802.11a/n/ac/ac Wave 2/ax

2.4 GHz: 26 dBm

5 GHz: 26 dBm

(Note: This is the total MIMO radio power, the same as:

2.4 GHz: 20 dBm/chain

5 GHz: 20 dBm/chain)

BLE: < 10 dBm

2.4G: -10 dBm to 20 dBm/chain

5G: -10 dBm to 20 dBm/chain

Wi-Fi:

• If the USB port is not used or the USB port works at the 2.5 W output power, there is no restriction.
• If the USB port works at the 5 W output power, the number of MIMO spatial streams on the 2.4 GHz radio decreases to 2x2.

Wired network port: Either the 2.5GE electrical port or SFP+ optical port can be used for data communication at the same time. If both ports are connected, the optical port is preferentially used for communication.

Wi-Fi:

• In versions earlier than V200R024C00, the number of MIMO spatial streams decreases to 2x2 on the 2.4 GHz frequency band, the maximum combined power is 23 dBm, and the 5 GHz frequency band is unavailable.
• In V200R024C00 and later versions, the number of MIMO spatial streams decreases to 1x1 on the 2.4 GHz and 5 GHz frequency bands, and the maximum transmit power is 20 dBm.

Wired network port:

• In V200R021C00, the rate of the 2.5GE electrical port is reduced to GE and the SFP+ optical port is unavailable.
• In V200R021C10 and later versions, either the 2.5GE electrical port or SFP+ optical port can be used for data communication at the same time. If both ports are connected, the optical port is preferentially used for communication.

Other ports:

The USB port is unavailable.
