In the special ops checklist, Paul recommends the following:

What happens if a portion of the commands are executed and the pass is lost for hours? Days?  
In the case that only part of the STF might be uploaded, it would be prudent to upload all the instructions except for the three which command the CEMs to higher voltage first, and then upload the remaining three commands.

Are we going to send the three CEM HV commands at the end of the STF? (actually, they could be uplinked just after the commands for the second step).
