Using Uninterruptible Power Supplies

Compaq recommends that your TaskSmart N2400 appliance be connected to
an uninterruptible power supply (UPS). Companies often have a UPS built into
facility power. Most cases require a separate UPS connected to the
TaskSmart N2400 appliance.
A UPS protects your TaskSmart N2400 appliance from power outages and
low-quality power situations, such as dips and spikes. During a power outage,
the UPS automatically detects the interruption in power and switches over to
an internal battery supply. The battery provides continuous power for a limited
amount of time. Power interruptions are often short lived, and the UPS enables
the TaskSmart N2400 appliance to continue providing file service until normal
power is restored. However, when power fails, the system must be powered
down. The UPS supplies a limited amount of power to complete essential tasks
and to power down the TaskSmart N2400 appliance, avoiding any loss of data.
The UPS communicates directly with your TaskSmart N2400 appliance
through a serial line connection. If the system is properly configured and the
serial line connection is established, the UPS notifies the TaskSmart N2400
appliance when power is interrupted. The TaskSmart N2400 appliance then
automatically initiates a coordinated power-down. In addition, many UPS
products can be remotely controlled and monitored through Compaq Insight
Manager.
For detailed information about connecting the UPS to your TaskSmart N2400
appliance, refer to the documentation shipped with your specific UPS product.
Compaq offers a broad range of UPS products and can be viewed on the
Compaq website. This website provides information about many types of UPS
options, as well as a sizing tool with which to choose the proper UPS for your
TaskSmart N2400 appliance.
