Turn on the power to the FEB

Instructions on how to power the FEB using MPOD with EPICS

FEB Power using Keithley: AVDDP: 5.5V, AVDDN: 5.5V, DVDD: 5.5V and flange power 5.5V (parallel to DVDD).

The MPOD web GUI is at ppa-mpod1.slac.stanford.edu (visible on SLAC internal network only).

MPOD power settings (max current, trip current, trip behavior, sense behavior) are set by ./mpod/setDefaults.py. You should not need to run this unless you need to change the settings.

Example SNMP commands for switching on/off channels or the crate are in mpod/on.sh and mpod/off.sh.

MPOD will not turn on unless the interlock is plugged in (DB9 on MPOD controller at the left of the crate), turned on (24 V on BK power supply next to chiller), and not tripped (red LED on flow switch = switch is powered and flow is above trip point).

Take a calibration run with expert SVT GUI

Start the DAQ:

$ cd /u1/software/software_new

$ source setup_env.csh

$ ./bin/frontEndTestGui

Click <read status> and make sure no error is seen. If so, check that the FEB is powered correctly.

Make sure the AxiXadc temperature is ok (50-60C).

Configure with config/FrontEndBoardConfigC01.xml

Click <read status> and check that more registers are found.

Turn on power to hybrids (see below)

Do a hard reset under commands/FebCore/HybridHardReset (current on AVDDP should drop ~100mA).

Click <Write config>.

Do a soft reset under commands/FebCore/HybridSoftReset.

Check that the hybrid currents measured are ok. Sync status for each channel can be seen in register RceCore/DataPath[x]/Synced, 1xf for powered channels.

Hybrid Power

EPICS control

Instructions for powering hybrids with EPICS.

Manual control

In the DAQ GUI: go to config and turn on power to hybrids using Register: HybridXPwrEn (X=0,1,2,3).

Click <Write config>. Check that it worked by reading status and voltages/currents.

Reloading PGP card drivers

Typically after a reboot we need to reload the pgp card driver.

$ cd /u1/pgpcard/software/driver_old/

$ ./pgpcard_load
