SOHO Daily Meeting Minutes for Wednesday, 21 February 2001
ANNOUNCEMENTS
-------------
People have noticed poor throughput to networks off of NASCOM. This
may be partially caused by the reconfiguration of routers by NASA.
The reconfiguration work is expected to last for another week. If
you have an urgent issue please call Paul Doupont (301) 286-5112.
Building 3: PMI is scheduled to install the batteries in 3-UPS-20 on Friday
2/23/01 from 8AM until 4:30PM. The UPS unit will be in bypass mode and the
load will be on commercial power during this activity. Escorts will be
provided by MSOCC maintenance personnel. No impact to operations is
expected. 3-UPS-20 supports the SOHO, ACE, W/P and XTE missions.
