NETGEAR recommends that you connect the ReadyDATA physically to one or more uninterruptible power supply (UPS) devices to protect against data loss due to power failures. Once connected, you can add up to three UPS devices to Dashboard to enable the ReadyDATA to monitor and manage them. The ReadyDATA supports SNMP UPS devices and remote UPS devices.
If you enable email alerts, the ReadyDATA sends a message if a UPS status changes. For example, if a power failure forces a UPS into battery mode, or when a battery is low, you receive an email message.
When any UPS battery is low, or when a power failure occurs, the ReadyDATA automatically shuts down gracefully. In a configuration with an optional expansion disk array that is also connected to a UPS, before the ReadyDATA shuts down, it saves data to disks in the expansion disk array. However, the expansion disk array does not automatically shut down. If the batteries in the UPS to which the expansion disk array is connected become low, the expansion disk array shuts down ungracefully, but data has already been saved and is therefore safe.
Both the ReadyDATA and expansion disk arrays have dual power supplies. For full power protection, all power supplies should be connected to UPS devices.
The ReadyDATA supports UPS devices managed over SNMP and UPS devices managed over a remote connection.
