You can switch between state-based schedules and event-based schedules at any
time that the two schedules are not in conflict by changing the State/Event slider.
Enable Wake on LAN
Wake-on-LAN is a way to remotely power up a network-attached device, like a computer
or storage system. This feature allows you to conserve power by keeping a device turned
off when it is not needed, but allows a remote system to turn it on when it is needed.
Wake-on-LAN works when one network-attached device sends a signal, called a magic
packet, to another network-attached device. If wake-on-LAN is enabled in the target
device, the packet signals the device to power up.
Your ReadyNAS system supports wake-on-LAN on the first Ethernet port (LAN 1) only.
By default, wake-on-LAN is not enabled.
To enable wake-on-LAN:
1. Log in to your ReadyNAS.
2. Select System > Power.
3.
If not already expanded, expand Wake On LAN.
4. Select the Wake On LAN check box.
What Is Disk Spin-Down
Disk spin-down reduces the rotation speed of your ReadyNAS disks. When the disks
are spun down, power consumption is reduced, the disks are quieter, and disk life is
extended. However, the disks must spin back up before the ReadyNAS can read or write
data to them. This can cause an apparent slowdown in disk performance and, depending
on the application, can cause time-outs. You cannot enable disk spin-down on systems
with more than 8 bays.
You can control whether spin-down is used, how long a period of inactivity is needed
before disk spin-down, and if used, what days and times it is enabled. If you use
spin-down and also use applications that automatically read or write to the disks, either
disable spin-down when the applications start writing to the disks, or verify that the disks
spin back up fast enough not to cause a time out. It can take up to 10 seconds for disks
to spin up. In some file server applications, a 10-second delay might be acceptable. For
