*Do not push the preamps all the way against the eurocard. Use the chimney bracket brace bar to push the preamp onto the eurocard. Simply attach the bar and tighten the bolts. The preamp will be properly located with respect to the chimney slots.

=== Controlling the electronics ===
See [https://docs.google.com/document/d/1h_cdGmiCDNpebsxfTyXRY9JQlQd3d6N6BcufDAcAnWU/edit this Google doc] for information pertaining to the electronics software and proper usage.

*The CPU should have an ethernet cable connecting it to the hub.
*The CPU should have an ethernet cable connecting it to the hub.
=== Setting up the crate for testing ===
*The crate will need to be connected to our network (ask Richard)
*The gate will need to be configured.
*CODA will require configuration files in order to run properly
== Testing the setup ==
=== Testing the dark box ===
*Use a camera with a 60 second exposure to test the light seal of the dark box
*Verify that signals are coming from the electronics by using an oscilloscope. High gain will allow you to see the dark rate.
*Similarly, verify that the pulser is providing signals by reading both outputs on the scope.
=== Testing the crate ===
*Turn on the pulser and the electronics
*By hand perform a run using the CODA interface
*Error messages will appear in the CODA interface

=== Setup and Procedure ===
=== Setup and Procedure ===
*The former procedure can be found [http://zeus.phys.uconn.edu/wiki/index.php/Fiber_Testing_Procedure here].
*The former procedure on setting up the fiber bundles and using the dark box can be found [http://zeus.phys.uconn.edu/wiki/index.php/Fiber_Testing_Procedure here].
*<b>Never</b> open the dark box when the electronics are turned on!
*Always remove the preamplifier board when installing fibers to prevent damage to the SiPMs.
*Make sure the 60 V power supply is <u>turned on first</u> and <u>turned off last</u>.
