Guard Band

To reduce the chances of ports fluctuating between powered and non-powered states, newly inserted PDs are not powered when the actual delivered power for the switch is within a preset value below the configured inline power budget for that slot or switch.

This band is called the guard band and the value used is 20 W for all ExtremeSwitching series switches. However, actual aggregate power can be delivered up to the configured inline power budget for the slot or switch (for example, when delivered power from ports increases or when the configured inline power budget for the slot is reduced).

If total consumed power is within the guard band, new ports are not powered up.
