Shutdown/Restart 3T Scanner - How2 Lab Notes, UCLA 3T MRI Lab

How 2 shutdown and re-boot the whole GE and ANMR systems (or only the AMNR system if needed) R. Lee

--------ORDERLY SHUTDOWN--------

1- take down the APD computer software (from apdII screen, pull-down from [file] menu to [shutdown APD system].

2- take down the GE 'Signa' computer software (from GE plasma screen, select [UTILITIES] and then select [shutdown].

3- take down the circuit breaker to the GE system (breaker #1 on the attached map of the 3T lab computer room).

4- take down the circuit breaker to the ANMR gradient cabinet (#2 on map).

5- take down the GREEN power switch to the ANMR (APD) computer (# 3 on the map).

6- take down the circuit breakerS in the front of the main ANMR cabinet (#4 on map).

7- take down the circuit breakerS in the BACK of the main ANMR cabinet (#5 on the map).

8- stand around and do NOTHING for about 3 minutes OR MORE with power down.

-------POWER-UP AND RE-BOOT-------

9- power up GE 'Signa' computer (#1) this will auto-boot signa scanner.

10- power up ANMR gradient cabinet (#2).

11- power-up the ANMR APD computer (#3) this will auto-boot the APD computer (up to the point of asking for a user ID and password (which will NOT be posted here on the web).

12- enter the APD password, bring-up the APDII window, and bring-up a shim window; and ONLY THEN power-up the rest of the ANMR cabinets.

IF YOU POWER-UP THE ANMR CABINETS

YOU BRING UP THE APD COMPUTER (AND BOOT UP THE APDII WINDOW) THE 2 COMPUTERS WILL NOT COMMUNICATE AND YOU WILL GET AN RPC (OR RP'something') ERROR THAT SAYS SOMETHING ABOUT 'TOGGLE RP ON/OFF'. ... TAKE DOWN THE APD COMPUTER AND START the APD boot-up OVER (Ralph)

13- AFTER the APDII software is up and running, then you can power-up the main ANMR cabinet (#4 in front of cabinet and #5 in back).

14- If you have taken the subject out of the magnet while re-starting the system, now would be a good time to put in a phantom and test the scanner (with both GE scans and APD scans).

15- GO FOR IT!!!!!!!
