Reset VME crates (old)

This procedure must be followed if one or more of the ADC boards are not initialized during the new_run procedure or if the end_run procedure fails with problems with the ADC boards.

Please note that board 28 must be restarted with the procedure described in Restarting board 28 below.

Restarting boards 0 to 27

ADC boards 0 to 27 are mounted on two VME crates on the two sides of the electromagnetic calorimeter. Each board has its own IP address:

• 192.168.62.3 is the crate hosting boards 0 to 13 (right side of ECal when seen from the back)
• 192.168.62.4 is the crate hosting boards 14 to 27 (left side of ECal when seen from the back)

The following instructions must be executed twice, once per IP address, while being logged on l0padme1 as daq (usual password).

1. Type "telnet 192.168.62.x 8100", where the x stands for 3 or 4, then type "CAEN" (uppercase!) and "↵".
2. Type "c" to display the crate map.
3. Type "o" and then "↵" to turn the crate off. Wait till you see the VME currents and fan speeds go to 0.
4. Type "o" and then "↵" again to turn the crate back on. Wait till VME currents and fan speeds are back to normal.
5. Type "q" and "↵" to exit, then "q" and "↵" again, "ctrl"+"]" to get the telnet prompt, and finally type "quit" and "↵".

Repeat the steps 1 to 5 for both IP addresses: all boards from 0 to 27 have now been restarted.

Restarting board 28

Board 28 is the ADC board collecting data from the diamond target. It is located in a small red VME crate vertically positioned beside the target/mimosa cross. Since July 2019 this crate is connected to a remotely controlled power supply so that it can be reset without accessing the experimental area.

To reset the board the shifter must be logged on l0padme1 as daq (usual password). From the DAQ directory the procedure to reset the VME crate is:

[daq@l0padme1 DAQ]$ tools/board28 reset
