Chapter 1 Managing Single Entities Overview Warning Voice over IP (VoIP) service and the emergency calling service do not function if power fails or is disrupted. After power is restored, you might have to reset or reconfigure equipment to regain access to VoIP and the emergency calling service. In the USA, this emergency number is 911. You need to be aware of the emergency number in your country. For information about this warning, see the “Important Notice” appendix. Overview In a Ci

Chapter 1 Managing Single Entities Creating an EnergyWise Domain Power over Ethernet (PoE) domain members and end points can also receive power from PoE switches or Cisco EtherSwitch service modules. For example, IP phones and access points connected to a PoE switch receive power from the switch. Creating an EnergyWise Domain An EnergyWise domain is treated as one unit of power management and is similar to a network-management community (for example, a VLAN Trunking Protocol [VTP] dom

Chapter 1 Managing Single Entities Power Levels Power Levels The devices in an EnergyWise network are from different manufacturers. To manage power usage consistently, EnergyWise uses a set of power levels. If a domain member sends an end point a request to change the power level, the end point determines the appropriate action.

Chapter 1 Managing Single Entities Configuration Guidelines Configuration Guidelines By default, EnergyWise is disabled on the switch. If you enter the no energywise level command, the switch does not immediately change the power level to the default. The power level changes when the switch restarts or when you enter the energywise level level command. For a switch with PoE ports, such as a PoE-capable switch: � When you add the switch to a domain, EnergyWise is enabled on the switch

Chapter 1 Managing Single Entities Configuration Guidelines If you use a wildcard for the day_of_month and specify the day_of_week, the event occurs on the day_of_week. If you use wildcards for both the day_of_month and the day_of_week, the event occurs on any day. – After you upgrade the software to an EnergyWise Phase 2 release or later, a configured recurring event might occur less frequently than before the upgrade. Reconfigure the event. � If you use the energywise level level
