Figure 4. Fan LED on a VTrak M310p/M210p cooling unit
Under normal conditions, the power supply, battery, and fan LEDs should display
green.
To check a component’s installation, follow the same procedure as replacing the
component, except that you reinstall the original component rather than a new
one. In most cases, this action fixes a bad connection and allows VTrak to detect
the component. If this action does not correct the problem, replace the unit. See
page 167 for instructions.
