Miteq NSU1
This is a New Switchover Unit (NSU) redundant switchover system with a fixed 1:1 configuration. This means that one backup unit is present for one primary unit. Other models can have other (non-)fixed configurations (e.g., NSU2 = 1:2 and NSUN = 1:1 to 1:12). If a primary unit fails, the backup unit will take over, on the condition that Redundancy Mode is set to Automatic.
If a primary unit fails, the backup unit will take over, on the condition that Redundancy Mode is set to Automatic.
About

Usage (2.0.0.X range)
General
This page allows you to check and modify the Unit Name.
Converter
On this page, the Converter Table shows the available converters in the redundancy chain. The NSU1 has a fixed configuration that always has one primary unit and one backup unit.
The Chain Position in Standby Mode shows which unit in the chain is placed in standby. In a normal setup, the value for this parameter is Backup Converter; however, if a primary unit fails, the backup converter takes its place, and the parameter value becomes Primary Unit.
System
This page shows the system's IP, Gateway, and Subnet Mask. These parameters can be configured.
Click the Clock Settings page button to view and configure the Internal Calendar/Clock.
The Redundancy Mode can be set to Manual or Automatic. In normal circumstances, it is set to Automatic. The Manual mode is mainly used for offline testing and maintenance. Local/Remote Mode makes it possible to switch between Local Control or Remote Control.
The Fault Status page button shows a summary of the statuses of the Power Supplies, Converter, and Switch Module.
Logging
To retrieve the values for the Event Log Table, Logging Status, and Number of Expected Entries, click the Get Logging button.
