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.

operation. When the system functions properly, the RUN Indicator is constantly flashing 
at a 0.5Hz rate. If this indicator ever goes to a steady state condition, either on or off, 
some malfunction has occurred. In addition, relative processor loading can be determined
