To use this Evertz Xenon multi - format router, first, make sure it's connected to the correct power supply. Then, connect your HD/SD input sources to the XE - IP32HX units. For outputs, you can use the XE - OP32HX - XLINK and XE - OP32HX units. Keep an eye on the fans. Since one fan in a PS0020 module and one in a XE - FAN module are already non - functional, check the other fans regularly. If any more fans stop working, it could lead to overheating. For maintenance, clean the router's exterior occasionally to prevent dust buildup. Also, make sure the power supply is always in good condition.
