MDM Trouble Report for 2006 Jun 25

Telescope: 2.4m
Observer(s): Halpern, Roberts (Columbia U.)
Instrument: Modspec

Problem(s) Encountered:
Shortly after dinner lightning struck very close, and the power
flickered off and on a couple of times, but the computers stayed
up.  A normal lightning shutdown was then performed.  The
commercial power remained on, but the generator ran for a while.
Rain was heavy for a while.

This message reports some anomalies that appeared when the
computers were turned back on a couple of hours later.

1. All the computers came up okay, but krakatoa's monitor
(still labeled 'pinatubuo') is scrolling rapidly and continuously 
with some messages, including 'file system full'.

2. The UPS fault light (red) is on, and it is squealing, so I
assume that we have no UPS right now.

3.  The mirror AC circuit breaker tripped.  (This also happened
in the previous morning, probably when I shut down, but I
hadn't noticed it.)

4.  The wireless network isn't working.

Also, I notice that the lightning shutdown procedure no longer
includes disconnecting the T-1 line from the router, and I
wonder if this is okay.

One apparent benefit of the shutdown is that some low-level
pattern noise on the Echelle CCD, which has been present for 
many days, seems to have disappeared.
