TRD run plan

See the run plan for the Fall 2015 run in this pdf, which includes the various radiator configurations which will be tested.

Before adjusting voltages

1. To check or set HV/LV, first ssh into a gluon machine (like gluon30 or gluon29). For example:
   • ssh hallgw
   • ssh hdfdcops@gluon30

Adjusting the HV

1. Before using telnet, ensure that nobody else is connected to the crate (using 2 telnets to the same crate will cause problems)
2. Telnet in with: telnet u2-10-top 1527
   • Login with the username: 'user' and the appropriate password.
   • The TRD is using the first 8 channels of slot 15 (or channel#'s: 15.0000-15.0007 in the right column), which is the very bottom set of channels.
3. To change one of the voltages (or other options), simply navigate to the appropriate channels with the arrow keys, type the desired voltage, and use the down or up arrows to enter the voltage.
4. After finishing, make sure to log out (use 'tab' to access the top menu and 'enter' to select options).

Adjusting the LV

To check the low voltage status, use the web:

1. On a gluon machine: "firefox --noremote" then go to "u2-9-mid"
   • The TRD uses U204, U205, and U206. U207 is also connected but is not being used for the fall 2015 run.

To set the LV (or any related parameters), use the appropriate set of the following commands:

1. To set the target output Voltage:
   • snmpset -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputVoltage.u204 F 6.65
   • snmpset -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputVoltage.u205 F 6.65
   • snmpset -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputVoltage.u206 F 6.65
2. To turn on channels:
   • snmpset -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputSwitch.u204 i 1
   • snmpset -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputSwitch.u205 i 1
   • snmpset -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputSwitch.u206 i 1
3. To turn off channels:
   • snmpset -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputSwitch.u204 i 0
   • snmpset -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputSwitch.u205 i 0
   • snmpset -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputSwitch.u206 i 0
4. To get the sense voltage:
   • snmpget -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputMeasurementSenseVoltage.u204
   • snmpget -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputMeasurementSenseVoltage.u205
   • snmpget -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputMeasurementSenseVoltage.u206
5. To get the current:
   • snmpget -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputMeasurementCurrent.u204
   • snmpget -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputMeasurementCurrent.u205
   • snmpget -v 2c -m +WIENER-CRATE-MIB -c guru u2-9-mid outputMeasurementCurrent.u206
