[widar-wg] CPCC Battleshort Fixture

[Sean Dougherty]

Kevin,

Why would the correlator be down for weeks if we lose the CPCC and the
spare? Isn't it a case of replacing the CPCC and associated software - if
so, does that take so long?

The discussion of CPCC spares prompted me to bring this up. 

Though it is difficult to imagine how we could lose both CPCCs and the
spare, the fact of the matter is that, if we do, the EVLA could be off the
air for weeks.

A simple 'CPCC bypass' would be RPMIB-cable terminating connectors that are
hard-wired to cause the boards to be powered up and the rack fans to be set
to high.  With either set of CPCC cables plugged into these terminators, the
system would run.

This should be relatively inexpensive to implement (connectors, +5V power
supply, panel, Kerry).  

Does this sound like something we should do?

Kevin
