Network UPS
An Uninterruptible Power Supply (UPS) is a device that works off of a battery and keeps devices
that are connected to the UPS port running, for at least a short time, if the main power source goes
out. When a My Cloud device is connected to a UPS, the drive will automatically shut down when
the UPS is drained to a specified percentage. See Knowledge Base Answer ID 11852 for a list of
supported UPS devices.
UPS Connection for a Single My Cloud Device
For a single My Cloud device, the connection to a UPS is accomplished through a USB connection
from the My Cloud device to the UPS.
UPS Connection for Additional My Cloud Device(s)
Additional My Cloud devices on the same local area network (LAN) can be added to the single,
My Cloud-to-UPS scenario mentioned above using a master/slave protocol. The UPS Master
device (the first, or single, My Cloud device connected to the UPS) controls the additional, slave
My Cloud device(s).
The slave My Cloud device(s) communicates with the UPS Master device via IP address. If the
UPS is discharged to the specified percentage, all of the My Cloud slave devices will automatically
shut down properly.
Use the following procedure to set up a UPS Master and Slave Connection.
