MAE West is up again (fwd)

Interesting that GS-1 isn't on the "main DC plant"... I thought this GS
was an important one, considering all the OC-3's go to it :-)

MAE West should be alive now.  If you're still seeing problems, please
contact our NOC and let them know!

Here's what happened, as near as I can make out:

Sometime during the night there was a power failure affecting at least the
part of the building where the MAE is located.  This went undetected long
enough for the UPS powering one of the Gigaswitches to drain, so the
Gigaswitch lost power.

When power was restored, the Gigaswitch refused to come back up, claiming
that it's management memory was corrupted.  We were finally able to clear
the management memory and rebuild the Gigaswitch configuration from
scratch, and it finally came back to life.

For the short term, we're going to put that switch on the main DC power
plant (as all the others are) which has a much longer lifetime and is
watched better.

We'll also try to find out what happened with the Gigaswitch management
memory.
