Remote Wake Up lets you remotely wake up a single node or a group of powered-down nodes in your network if the network card on the node is enabled for Wake-on-LAN.
Waking up a device that has multiple NICs (Network Interface Cards) is successful only if one or more of the NICs is configured for a subnet that contains the device that is broadcasting the Wake-on-LAN packet.
Before waking up the managed devices, the following requirements must be fulfilled:
Ensure that the network card on the managed device supports Wake-on-LAN. Additionally, ensure that you have enabled the Wake-on-LAN option in the BIOS setup of the managed device.
Ensure that the managed device is registered with the ZENworks Management Zone.
Ensure that the remote node is in a soft-power off state. In the soft-power off state, the CPU is powered off and a minimal amount of power is utilized by its network interface card. Unlike the hard-off state, in the soft-off state the power connection to the machine remains switched on when the machine is shut down.
To perform a Remote Wake Up:
In ZENworks Control Center, click .
Click or to display the list of managed devices.
Select the device to wake up.
Click to display the Wake Up dialog box.
Select one of the following options to specify the servers to send a wakeup request to the managed devices:
Automatically detect the server: ZENworks automatically detects the Primary Server closest to the managed device. If the server and the remote device are in different subnets, ensure that the router connecting them is configured to forward subnet-oriented broadcasts on UDP port 1761.
Use the following devices: Click to select a proxy device that exists in the same subnet as the device you want to wake up.
If the router is configured to forward subnet-oriented broadcasts on UDP port 1761, a proxy is not required.
(Optional) Select one of the following options to specify the IP address to be used for sending the wake-up broadcast:
Automatically detect the IP address: ZENworks automatically detects the default broadcast address of the subnet to send the wakeup broadcast to the managed device.
Use the following IP address: Specify the IP address to send the wakeup broadcast to the managed device, then click .
In the option, specify the number of attempts to wake up the device. By default, it is 1.
In the specify the time period between two retry attempts. By default, it is 2 minutes.
Click .
The default values for the and the Time Interval between Retries options are configured at the zone level. You can override these values at the device level.
