* Understanding IEEE 802.3af Standard:
* IEEE 802.3af, also known as PoE (Power over Ethernet), specifies the standard for delivering power over Ethernet cables.
* This standard allows devices like IP phones to receive power along with data over the same cable.
* Maximum Power Allocation:
* According to the IEEE 802.3af standard, the maximum power that can be delivered to a powered device is 15.4 watts.
* This power is delivered over Category 5 (Cat 5) cables or higher.
* EX Series Switches Compliance:
* Juniper EX Series switches with PoE support adhere to the IEEE 802.3af standard.
* Thus, each PoE port on these switches can allocate up to 15.4 watts to connected devices.
