Power Up Equipment

Cold start power up after mains failure / Service Operations / or at Start-of-Day

NOTE: "The main electronics cabinet has been equipped with a power failure release main switch to ensure proper boot-up sequence of the computers. The following instructions are to be used after mains power to the main electronics cabinet has been off due to mains failure or because the power to the three isolation transformers in the IHR tank room has been disconnected e.g. for service operations".

Powering Up the Internal Helium Recycler (IHR) (cabinet T3)

1. Make sure the valves are as per this Figure 7.38.
   • The valves shouldn't have been changed from their defaults since MEG installation.
2. Make sure the small Mode switch on the cryocooler compressor is set to remote control mode (position 2).
3. Turn the main power switch on the cryocooler compressor to On.
4. In the Helium Recycler cabinet, keep the UPS power button pressed down for a few seconds.
5. Wait for the control PC to power up automatically.
   • The control PC power-up takes about one minute.
6. To verify that the system started up, monitor the LEDs on the door of the Helium Recycler Cabinet.
   • The LED/s indicating the latest active operating mode come/s on.
7. To continue normal operations, click the Normal Mode button on the Service GUI.

Powering Up the Main Electronics Cabinet (cabinet T2)

NOTE: The Main Electronics Cabinet (T2) is protected by a UPS (UPS21), situated in the IHR tank room (G24).

The Power Control Panel of the Main Electronics Cabinet has three switches. These MUST be powered on in the correct sequence.

INDEX
1. Main switch (with no-mains release).
2. Main (DSP) Electronics (MEG & Bioamplifier/EEG) green rocker switch.
3. Preamplfiers (MEG & Bio/EEG) green rocker switch.

Procedure

1. Boot/Power Up the DACQ Workstation ("Sinuhe") as shown below. Wait until it boots normally (shows Log In prompt).
2. Power on the Eaton UPS, labelled "UPS21".
   • Switch on the Mains socket powering the UPS21.
     • The UPS front panel display illuminates, and shows a status of “UPS initializing ...”.
   • Verify that the UPS then transfers to Standby mode (“UPS on standby”).
   • Press the "On/Off" button on the front panel for at least one second.
     • The UPS front panel display changes status to “UPS starting ...”.
   • Check the UPS front panel display for active alarms or notices. Resolve any active alarms before continuing.
   • Verify that the green Power On LED illuminates solid, indicating that the UPS is operating normally.
   • Switch on the equipment that is connected to the UPS21 (see below).
3. Switch on the Watchguard Firewall and Network Switch, in the Side Room Comms cabinet. Wait until both have started up, indicated by any Self test and Fail LEDs extinguishing
   • Both Mains plugs are attached to sockets protected by UPS21. Make sure both socket switches are turned on.
4. On the Power Control Panel of the Main Electronics Cabinet, ensure that the green rocker switches, Preamplifiers (3), Main (DSP) Electronics (2), are in Off position.
5. Inside the Main Electronics Cabinet, the individual power supply units are connected to outlet socket strips located in the rear of the cabinet. Ensure that the power cords are in place.
6. Switch on the Main Electronics Cabinet power by turning the Main switch (1) on the Power Control Panel to the On position. The switch will automatically turn back into the Off position if Mains voltage is too low.
7. After turning the Main switch (1) to the On position, wait until the ethernet switch has started up, indicated by the Self test and Fail LEDs extinguishing.
   • Bootup takes about one minute. The cabinet roof fans and auxiliary equipment, e.g the intercom, should also now power up.
8. Switch On the Main (DSP) Electronics green rocker switch (2) from the Power Control Panel.
   • Wait until all the controller cards in the racks show steady green Run LEDs and the red Fail LEDs are off.
   • Boot-up takes about 30—60 seconds.

   If the bootup fails, open the back door of the main electronics cabinet and check the indicator LEDs of individual power supplies.
   The Main (DSP) Electronics racks must be booted before the Preamplifiers because the Preamplifiers are controlled by one of the main electronics boards.

9. Switch On the Preamplifier green rocker switch (3) from the Power Control Panel.
10. Run a Restart Acquisition Programs (RAP) by double-clicking its icon in the Maintenance toolbox on the DACQ Workstation ("Sinuhe").

NOTE: Each time the MEG front end is powered it must be initialized by running a RAP.
Also the latest tuning file must be loaded, via Tuner.
NOTE: For optimum noise performance, let the Preamplifiers stabilize for approximately 1-2 hours before commencing MEG measurements.
