<p>Before sending it for repairs it might be useful to try upgrading
the firmware and check if Fast Electronics group could take a look
at it (cc'd Chris). We have other spare MPOD crates available.<br>

<div>DSG has been developing a test station to test SVT's MPOD
power supplies using SVT LV/HV crate #5 that been in DSG's
control room.<br data-mce-bogus="1">

<div>In development of the tests station, we have found that SVT
LV/HV crate #5 and its control board do not work correctly.
The control board for this crate stopped working and now the
crate no longer stays powered. </div>

<div>The crate was tested with an additional MPOD controller
card (Serial # 4688009; borrowed on Wednesday January 31,
2018) to confirm the crate is no longer working. The control
board borrowed on Wednesday has been returned to MPOD crate #2
in EEL 125 and it was verified that the returned control board
works correctly and the crate is able to be powered.<br

<div>After contacting WIENER and describing the issues with both
the crate and control board, they recommend sending both in
for repairs. </div>

<div>Because this MPOD crate is a spare for SVT, Amrit has
advised that it is Hall B's decision on whether to send the
crate and control board off for repair. If they should be sent
for repairs, Hall B or SVT group should submit the RMA request
to WIENER and arrange the shipping.<br data-mce-bogus="1">
