Multispeed Backbone Switching - NETGEAR MS510TXM Hardware Installation Manual

8-Port Multi-Gigabit/10G Ethernet (Ultra60 PoE++) Smart Managed Pro Switch with 2 SFP+ Ports
If the power requirements for attached devices exceed the total power budget of the
switch, the PoE power to the device on the highest-numbered active PoE port is disabled
to make sure that the devices connected to the higher-priority, lower-numbered PoE
ports are supported first.
Note: Although a device is listed as an 802.3bt PoE++ powered or 802.3atPoE+
powered device, it might not require the maximum power limit that is specified by its
IEEE standard. Many devices require less power, allowing all 8 PoE++ ports to be active
simultaneously when the devices correctly report their PoE class to the switch.

Multispeed backbone switching

You can use the switch as a multispeed backbone switch in a network that serves network
components such as high-speed servers, high-speed storage platforms, and 1G and
2.5G computers. The switch supports speeds from 100 Mbps all the way up to 10G.
In the following figure, the speed icons indicate the speed of the connection. The yellow
cable indicates the uplink connection to a network router and to the Internet.
