ReadyNAS OS 6.1
Optional Uninterruptible Power Supplies
Your ReadyNAS system supports the use of optional uninterruptible power supply (UPS)
devices. This section discusses UPS basics, configuration and management.
Uninterruptible Power Supplies
NETGEAR recommends that you physically connect the ReadyNAS to one or more
uninterruptible power supply (UPS) devices to protect against data loss due to power failures.
Once a UPS is connected, you can use the ReadyNAS local admin page to monitor and
manage it.
If you enable email alerts, the ReadyNAS sends a message when the status of a UPS
changes. For example, if a power failure forces a UPS into battery mode or if a battery is low,
you receive an email message.
When any UPS battery is low or when a power failure occurs, the ReadyNAS automatically
shuts down gracefully.
UPS Configurations
The ReadyNAS supports UPS devices managed over SNMP and UPS devices managed
over a remote connection.
UPS Devices Managed over SNMP
An SNMP UPS lets the ReadyNAS query the manufacturer-specific Management Information
Base (MIB). The ReadyNAS monitors and manages the UPS using the SNMP protocol. The
Ethernet connection between the UPS and the ReadyNAS passes through a switch.
UPS Devices Managed over a Remote Connection
A remote UPS is attached to a remote server, such as a ReadyNAS or a Linux server that is
running Network UPS Tools (NUT). The ReadyNAS monitors and manages the UPS over the
remote connection. The Ethernet connection between the UPS and the ReadyNAS passes
through a switch.
Manage UPS Devices
You can manually add, edit and remove UPS devices as well as monitor the status of
connected UPS devices.
Add a UPS
If your UPS is not automatically detected when you connect it to your ReadyNAS system, you
must manually add the UPS.
