Power Requirements For Ap41 - Juniper AP41 Deployment Manual

Power Requirements for AP41

The AP41 requires 802.3at (PoE+) power, and it requests a maximum of 25.5W. Ensure to connect an
AP41 or AP41E to an 802.3at or PoE+ switch. The AP41 requests 19.5 W to provide wireless
functionality, without PoE out and USB port support. You can use any of the following options to power
on an AP41:
• Power over Ethernet Plus (PoE+) from an Ethernet switch
We recommend that you use an Ethernet cable with a maximum length of 100 m to connect the
access point (AP) to the switch port.
If you use an Ethernet cable that is longer than 100 m by placing an Ethernet PoE+ extender in the
path, the AP might power up, but the Ethernet link does not transmit data across such a long cable.
You might see the status LED blink yellow twice. This LED behavior indicates that the AP is unable to
receive data from the switch.
• PoE injector
• 12 VDC power supply
