New procedure since October 2020

Restarting board 0 to 27

You have to enter in the new Damage Control System webpage on https://l0padme1:8888/ and enter with YOUR username/password : all operations are logged and we want to know WHO did an operation and WHEN.

All the shifters should be authorized to access the new DCS. The (hopefully updated) list of authorized accounts can be found here. In case of doubts and/or if you do not have yet an authorized userid, you are free to call "expert" people doing the operation (and ask Venelin to provide you with an autorized userid on the DCS control).

Once you are in the Damage Control System page you have to go to the Configuration menu (top of page, green) Once there you will see DCS System with a round circle near it on the right. Click on the circle and it will start display its dependencies :

• PADME/Padme Experiment

Here again click on the circle on the left

It will start displaying its dependencies (each voice with a round circle on its right) :

1. calorimeter/calorimeter
2. DAQ system/DAQ crates
3. vetos/the vetos

Click on the circle near DAQ system/DAQ crates and it will show you (with "partial op." buttons on the right) :

1. Target PW
2. vme left
3. vme right

You have to press normally the "partial op." button and only AFTER switch to the Run Ops page from its menu on the top of the page (green) to actually execute the "transition" you have requested: till now no operation has yet been made

Once in this page (with the person making the operation listed on the left) you will see the operation request you have made with 2 buttons on the extreme right :

• check
• stop

Press on check and it should display start and stop buttons if the crate is OFF, or if the crate is ON you will only see a stop button.

NOW you have to press the stop (or start button; it depends on what you have to do) and wait till the operation has finished.

If you have pressed the stop button to pull down the crate the operation line should disappear from the list.

if you have pressed the start button to pull up the crate you should next see the line with ONLY the stop button.

Please control on the new DCS monitor page http://l0padme1:18888/#menu_experiments_submenu_padme_vme;theme=slate if the procedure has actually done what you expected (wait : the monitor line points udate ONLY each 30 secs, so probably you have to wait to see the operation executed).

Now you can return to the welcome user (your username) page (top page, green) and logoff from there.

Good luck !!!!

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/power_board28 reset
Resetting Board 28 - Please wait...
Board 28 is now OFF
.........
Board 28 is back ON

OLD procedure -- discouraged by now

Restarting board 0 to 27

Easy procedure

Connect to dcs@l0padme1 and use the command "off_vme_left" to turn off the crate VME on the left of the calorimeter and "off_vme_right" to do the same thing on the right crate. Turn them back on using "on_vme_left" and "on_vme_right". For board 28, please scroll for the instructions.

Less-easy procedure

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.

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.

1. Type "telnet 192.168.62.x 8100", where the x stands for 3 or 4,
2. then type "CAEN" (uppercase!) and "↵".
3. Type "c" to display the crate map.
4. Type "o" and then "↵" to turn the crate off. Wait till you see the VME currents and fan speeds go to 0.
5. Type "o" and then "↵" again to turn the crate back on. Wait till VME currents and fan speeds are back to normal.
6. Type "q" and "↵" to exit, then "q" and "↵" again, "ctrl"+"]" to get the telnet prompt,
7. 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.
