ReadyNAS OS 6.4 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 We recommend 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. It does not support monitoring over USB. 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. System Maintenance 200
