Chapter 11: Troubleshooting the Emulator
Problems with the Emulation Probe
If the power up self test fails, the RESET LED will flash the number of
the test, then stay lit.
If any of the LEDs fail to change, or all of them remain on, there is a
system failure.
Following power up, the LEDs will enter one of the following states
shown on page 164.
Starting a user interface will change the pattern to the one requested
by the interface.
If the power up self tests fail, try the following:
❏
Check and reset the LAN address. LAN powerup failures will occur if the
emulation probe does not have a valid link-level address and IP address.
❏
Disconnect all external connections, including the LAN, serial (RS-232),
and BNC break and trigger cables, then cycle power.
❏
To ensure that the firmware is working as it should, reprogram the
firmware, then cycle power.
