Power Sources and Consumption
• The AP supports direct DC power and Power over
Ethernet (PoE)
• When both power sources are available, DC power takes
priority over PoE
• Power sources are sold separately
• Direct DC source: 48Vdc nominal, +/- 5%
• Power over Ethernet (PoE): 48Vdc (nominal) 802.3af/802.3at
compliant source
• When powered by a direct DC power source, the AP will
operate without restrictions
• When powered by PoE and with the IPM feature enabled,
the AP will start up in unrestricted mode, but it may apply
restrictions depending on the PoE budget and actual
power. What IPM restrictions to apply, and in what order,
is programmable.
• When powered by PoE with the IPM feature disabled, the AP
will apply some fixed restrictions:
- The USB interface is disabled when using an 802.3at
PoE power source
- The USB interface and second Ethernet port (E1 if E0 is
used, otherwise E0) are disabled, and both radios are
restricted to 2x2 operation (AP in dual-radio mode) or
1x1 operation (AP in dual-5 GHz mode) when using an
802.3af PoE power source
• Maximum (worst-case) power consumption:
- DC powered: 20.0W (AP in dual-radio mode), 22.8W
(AP in dual-5 GHz mode)
- PoE powered (802.3at): 21.9W (AP in dual-radio mode),
25.1W (AP in dual-5 GHz mode)
- PoE powered (802.3af): 13.5W
- 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 6W (DC) or 6.6W (PoE)
