7.1 Overview

This chapter describes the procedures used to isolate hardware faults. Three push- buttons and eight status Led provide verification of TankGate proper operation. If the TankGate is not functioning normally, the user is able to troubleshoot the device by performing one or more procedures using the three push-buttons. These push-buttons and indicators are also described in the Motherboard & I/O Expansion Module Configuration chapter.
