Reset Buttons
Two reset buttons are provided on the front panel of the RACK2.
HW-R
Pressing this button initiates system hardware reset. (Same effect as disconnecting
and reconnecting power.)
SW-R
Pressing this button in combination with the
HW-R
button performs a system restart
without loading the program (refer to “Troubleshooting Communications” on page
23). Pressing it alone momentarily while the system is running restarts the program.
RACK2 Indicators
There are 23 LED indicators on the front panel of the RACK2 and 10 LED indicators
on the rear panel.
PWR
This LED illuminates when the RACK2 receives power from the external power
supply (sold separately).
NET
This LED illuminates when the CPU is processing data or communicating with
system hardware. Examples include: a button pressed at the local or a network panel,
data being sent out of either serial port.
ERR
This LED illuminates when one or more error conditions are detected by CPU2. This
may be the result of hardware or software failure, hardware incompatibility with
software definitions, a programming error, or a connectivity problem.
