Unit Identify Mode
In addition to the standard indicator modes described above, there is a Unit Identify
mode, for troubleshooting. In large systems, with multiple units in a rack and multiple rack
locations, this is not always easy. The Unit Identify mode causes the front panel display back
light to illuminate and flash and makes it easy to match the physical unit in a rack with the
virtual unit displayed in the VN‑Matrix Enterprise Controller GUI.
The mode can only be triggered by a command from the Enterprise Controller. It is not
available in smaller systems where a VNM250 device is used as a controller.
