Configuring PoE

PoE supports a full set of configuration and monitoring commands that allows you to configure, manage, and display PoE settings at the system, slot, and port level. To enable inline power, or PoE, you must have a powered switch or chassis and module.

Note

Note

On a modular switch, if your chassis has an inline power module and there is not enough power to supply a slot, that slot will not power on; the slot will not function in data-only mode without enough power for inline power.

To configure inline power, or PoE, you must accomplish the following tasks:

  1. Enable inline power to the system, slot, and/or port.
  2. On modular switches, reserve power to the switch or slot using a power budget.
  3. On modular switches and Summit X430, X440-24p, X450-G2, X460-G2, X460-24p, and X460-48p switches, configure the disconnect precedence for the PDs in the case of excessive power demands.
  4. Configure the threshold for initiating system alarms on power usage.

Additionally, you can configure the switch to use legacy PDs, apply specified PoE limits to ports, apply labels to PoE ports, and configure the switch to allow you to reset a PD without losing its power allocation.
