802.3bt support

IEEE 802.3bt standard enables delivering up to 90W of power across a network cable supporting all standardized copper link speeds of up to 10G-BaseT, commonly referred to as Power over Ethernet (PoE) or 4-Pair PoE. Earlier IEEE 802.3af and IEEE 802.3at PoE specifications permit Type 1 and 2 PSEs to deliver power over 2-pairs of a 4-pair Ethernet cable. The IEEE 802.3bt specifications permit Type 3 and 4 PSEs to deliver power over all 4-pairs of the Ethernet cable enabling higher efficiency and power delivery to remote devices.

IEEE 802.3bt standard devices are backwards compatible with previous PoE standard devices, IEEE 802.3at and IEEE 802.3af, allowing existing PoE devices to deliver or receive power up to their maximum IEEE 802.3 PoE classification.

The 2930M switches provide modular stacking, modular 10GbE, 40GbE, or Smart Rate multi-gigabit ports, and hot-swappable power supplies for redundancy, up to 60W PoE per port (up to 1440W PoE total**) for powering APs, cameras, and IoT Internet of things (IoT). Describes physical objects with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communications networks. devices.

** The front panel ports are able push up to 60W of PoE per port. For 1440W PoE, 2x JL087A Aruba X372 54VDC 1050W 110-240VAC Power Supplies must be installed.
The 802.3bt support is available only on two switch models of 2930M, R0M67A and R0M68A.

The following Aruba 2930M models provide up to 60W PoE per port** and are compatible with IEEE 802.3bt standard (Class 6):

  • Aruba 2930M 40G 8 Smart Rate PoE Class 6 1-slot Switch (R0M67A) - 36 1GbE ports; 8 Smart Rate ports (1, 2.5, 5, 10GbE); 4 dual personality ports (1SFP, 1G BASE-T - includes PoE)
  • Aruba 2930M 24 Smart Rate PoE Class 6 1-slot Switch (R0M68A) - 24 Smart Rate ports (1, 2.5, 5GbE)

Some of the advantages of 802.3bt support includes:
