<br>
Conditions in the hall have stabilized and the network updates
have been performed. <br>
<br>
Each rack may have up to three AC power sources: UPS (blue
outlet), 110VAC strip and 208VAC (orange outlets). During the
power outage period, the 110VAC strips were turned off and these
power all of the network equipment in a rack. Chris and Nick will
turn the strips back on this morning. Feel free to turn the power
on on crates and chassis as needed.<br>
<br>
REMINDER: BCAL, CDC and FDC - Before turning on the power (LV, HV,
Bias) to the frontend electronics, please verify that the cooling
systems are operational and at nominal conditions.<br>
<br>
Best regards,<br>
Fernando<br>

In preparation for the power outage period, all the electronics on
the racks in the hall and the tagger will be turned off today,
with the exception of those already on UPS power. Conditions
permitting, all the electronics will be powered up on Monday,
6/29. This will allow the hall and tagger environments to
stabilize at nominal operational conditions (temperature,
humidity) following the power outage.
<br>
<br>
Electronics off period: 6/11/2015 - 6/29/2015
<br>
<br>
Subsystem owners should ensure that all the other powered
equipment is either off or on UPS power, i.e. cooling, gas, etc.
As indicated by Tom, lights will be on backup power for most of
the period. Also, coordinate any access to the hall or the tagger
buildings during this period with Tom.
<br>
<br>
Best regards,
<br>
Fernando
