Determining Wake on LAN Support for Computers

Overview

The Wake on LAN (Windows) or Wake on Demand (Mac) setting must be enabled to use the Surveyor Wake on WAN functionality.

This article provides information that helps you determine if the Wake on LAN (Windows) or Wake on Demand (Mac) setting is supported by your computers and how to determine if the setting is enabled.

Information

Wake on LAN (Windows)

In most cases, Windows computers are Wake on LAN capable when they are:

  • Purchased and deployed within the last five years.
  • Qualified as Energy Star version 4.0 and later.

The wake on LAN setting may not be enabled by default. The following behaviors indicate that this setting is not enabled:

  • They can transition to a low power state, but they wake immediately after.
  • You have followed the steps for enabling Wake on WAN, and clients do not respond to wake requests sent by Wake on WAN proxies (originating either from a power scheme or an on-demand wake request that you initiated in the Administrator console).

To test Wake on LAN support among a group of computers, you can send a wake request manually from the Administrator console.

Wake on LAN is enabled in the Windows computer's BIOS and the network card (NIC), so settings vary among hardware manufacturers. If you cannot determine whether a computer supports Wake on LAN by using these simple guidelines, the best place to find information specific to the computer is in the documentation provided by the hardware vendor.

NOTE: Surveyor clients that do not support Wake on LAN can still receive wake requests that you schedule in the Administrator console. You can also continue to measure power use on those clients. These clients are also good candidates for Wake on WAN proxies. For information, see Set a client to be a preferred Wake on WAN proxy.

Wake on Demand (Mac)

Starting with OS X v10.6 (Snow Leopard), remote wake, called Wake on Demand, is enabled by default. It works along with the Bonjour Sleep Proxy service, which runs on an AirPort Base Station or Time Capsule.
