Tech Staff Meeting Notes November 8, 2010
The top priority is always repair of down stations.
NM problem stations
ET problem stations
NetOpsV will be focused on AQMS on February 2 and 3 in Pasadena.
The CERI Holiday party is scheduled for December 3 at 11:30. We're using an outside vendor so the cost is $10.
December Show n Tell is monday, December 6 at 1:30 in the war room. Jim will show us all about mss100's.
ISIS routine maintenance & service 2010:
Almost all stations have been serviced in 2010. What's remaining?
Down
PEBM/Jim (bad timing but status stream says its locked and good to 4us)
NHIN/Dave (bad time in adsend, need new xlak)
MPH.LL*/Jim
Strongmo Down
HDAR/Chris comm issues between mud island and the weigh station?
RDST/Steve ip/mss issues. CBHT/Chris mss is connected, no contact with cmg5
MCAR/Chris down most of the time. Occasional brief periods of connectivity.
The staff meeting notes show it needs a router and mss100 upgrade.
GSAR requires frequent resets. Somehow port forwarding config got bolluxed. Needs a site visit to reconfig.

Node reset instructions are at
/gaia/smeagol/home/seisadm/ew/node.notes/phone.reset.proc
Note that using the pc reset option with the GX620 system can cause it
to hang. Only power cycles are recommended. The reset option has been
disabled at most nodes.
MKTA
DSL is now installed but the networking is slightly different from lnxt. Steve is working out the problems making both the dsl and the dbb simultaneously accessible.
Construction is ongoing at the mill.
LNXT:
Chris is checking on the cost of a service contract for the generator.
NMAD:
Need alternate comm path. Telecom says dsl isn't available (though we once had ISDN).
AZTN: Replace XLAK clock.
CERI:
The DBB firewall installed and operating. Only specific ip's are allowed through. You need to use the route command to manually add a route. Evertying behind the firewall is the same D ip number but with 10.156.1 instead of 141.225.156. Remaining items include:
Ownership, Operation, and Maintenance of the four Charleston, SC stations (C1SC, C2SC, ADSC, and TRSC) will be turned over the Univ. of SC at Columbia. John is waiting to hear back for a specific date for site visits in early December. Data flow will need to be redirected to Columbia (firewalls and etc taken care of). Then those feeds will get added to the CO network export to CERI. The stations will keep the same name but the network code will change (from NM to CO).
I added the firmware column as that seems to be causing problems at some sites. Are there problem sites that have all the hardware but need new firmware that should be added to this list? Year3 upgrades
| station | yr3 hardware | router | mss100 | firmware |
|---|---|---|---|---|
| RDST | Y | Y | N | ? |
| MCAR | Y | N | N | ? |
| CUET | N | ? | Y | ? |
| MKAR | Y | Y | Y | ? |
| CBHT | N | N | N | ? |
| COLT | N | N | N | ? |
| GILT | N | N | N | ? |
| NAIT | N | N | N | ? |
| NMEM | N | N | N | ? |
| TUMT | N | N | N | ? |
Replace foam rubber plugs at all year 1 stations (need to notch it to accomodate the GPS pods): ASAR, CBHT, CUET, CVTN, HDBT, LNXT, MCAR, NAIT, SFTN & TUMT.
NAIT: Couldn't get the NWS cable modem to cooperate at NAIT (firewall?). Dean was going to ask Comcast about it and maybe get a new modem. Steve will follow up.
CVVA is upgraded but there remains an unresolved issue with the firewall Steve is working with Merritt Reagan NGC to get them resolved. Merritt says their it security has been slow to respond but they're still working on this.
Al and Jim have all the issues resolved and we're now able to download 200 sps triggers. These are the guidelines.
HDBR
The aztnworm upgrade broke the disk sharing with the win98 box. Mitch
sent a budget and justification to Sharam. This project needs to be
either upgraded to replace the substandard PMD dataloggers, or it
needs to be decommissioned (see HDBR notes from
).
Recorder #5 has a bad disk bay.
HDAR
Bad CMG5 E/W.
Not getting broadband feed.
HDBT
Replace two bad mss100's.
Bad 100' accelerometer.
Down
Strong Mo Down
Gain Channel Problems
Unknown
FPAL is about 10 degrees warmer than the Arkansas stations so some
shade or forced ventilation may be in order.
Mitch needs to get off his butt and select the 3 non-ARRA ET stations
for upgrade.
STAR Node
BHT. Chris reports that it is time to seriously pursue another site as
access is even difficult by 4-wheeler. David reports moving it will take
all the fun out it, what's the worst that could happen? John said that
folks at Cumberland Trail State Park said we can put the station at
another spot on Black Mtn. which is just a couple of miles NE of the
present location. It is accessible by a paved road. We can pursue that
or I can look for something that will put it further NE to get it more
equidistant between DYTN and WMTN. Right now it is awfully close to DYTN
and BCRT. Mitch likes the idea of splitting the difference between DYTN
and WMTN. John will dig out his old notes and starting looking around.
BRBC Node
Power upgrades: TVNC, RBNC, and TRYN.
The NC state park permit for GFM is on the way. Anyone going to GFM needs a copy of the permit with them.
TRYN: Hardware is removed from the tower and will be reinstalled when
the new one is complete.
There seems to be a strange, repeating signal on many of the stations,
most notably on WSNC/RBNC. It repeats about every 14 minutes and lasts
about 1 sec. Example data are in
/gaia/home/mwithers/public_html/STAFF/Analog/2010/20100910_051500_MAN.
Click this picture of it on CCNC.
John listened for them on the spectrum analyzer at the BRBC node and reports:
MTTN Node
Greentop is getting a new tower too. There will not be internet up at
the mountain, so we need to find a place to transmit to. We should be
able to hit just about anything in Knoxville, Maryville or Pigeon Forge;
is there a preference?
A new prof at UNC-CH, Lara Wagner, might be interested in co-locating
some of here equipment (Nanometrics broadbands & digitizers), with as at
VHTN or LRVA. She is setting up a transect array of 10 stations in
western NC.
James has a very nice SOH website at
http://www.ceri.memphis.edu/people/jpdavis/gama/results.html.
PTGV was losing satellites indiscriminately. There another sensor
package transmitting right at the gps stations that could be causing
interference. The hosts assured James that they aren't the source of
the problem though is seems to be clearing up as their experiement
completes and more of their sensors go offline.
Most monuments need a new paint job and weed control. Mineral Area
Colege is the top priority.
MAIR is currently wireless. We have a cat5 surge arrestor and
permission to run the cable into the office (less than 50' though
it does need a hole in the wall).
There may be an issue with the NetR8 stopping satellite tracking
at temperatures below -5C. Ain't that special. Presumably those
in the west are applying heat and there will be a fix forthcoming
from trimble.
Need to replace older GPS-100 supply systems.
These stations still need to be steinerized: CVMS, MACC, HCES, MAIR, NWCC.
STLE, NMKM, and RLAP all need a charger upgrade. They are currently
working (and have been for a long time) so this is not necessarily a
top priority.
vent all cabinets.
Install network WatchDog Timers. Meremonte uses iboot. Is he
talking about the ones from dataprobe?
http://dataprobe.com/iboot-remote-reboot.php
The links for HALT and PEBM don't work as well with etherenet freewaves as they did with the serial versions.
HALT is getting lower loss cable, new connectors, and a better antenna. Mitch is checking whether we can
use the internet at the South Pemiscot school admin bulding (where gps station STLE is located) for PEBM.
CPCT upgrade is on deck.
BCRT, GMG, and GTTN along with the 3 TBD non-ARRA ET upgrades will be done in the spring.
All replaced DM24's and CMG40T's will be donated to Bob for distribution to his Argentinian colleagues.
Due to remodeling, we pulled K2 1738 from Firestation #2 in Dyersburg, TN in
February 2009. It is in the shop with accessories.
We pulled the k2 at Obion (station 2460) because the building it was
located in is being torn down.
The neic has a new metadata website at
https://geohazards.usgs.gov/smds/index.php?message=1.
John is finished populating it with info from our stations.
The seisnet group on umdrive is at
http://umdrive.memphis.edu/mwithers/seisnet
You will need your uuid and password.
Rotational sensor is feeding an earthworm but still has IRIG crosstalk problem to fix.
Its fine on an Oscope hooked to the output of the mux and looks fine in
LabView. Its bad when viewed with wave_viewer. Need to see what the sac
files look like to make sure it isn't just a wave_viewer feature.
Parker's old Suburban was sold on gov deals and our cut was about $1800. Chris is checking on doing
the same with old blue and, much to David's chagrin, 148. Funds will go toward a new truck. Chris
will begin specing the new vehicle (should it be a pickup with a shell or another suburban, or a panel
truck, or something else?).
The pink palace display now includes a heli connection for MPHB. Need to
retrieve any remaining hardare (e.g. antenna and reciever on roof).
3890 Power Chris is going to make a diagram for 3890. Good luck son.
3876 Power Chris is going to make a diagram for 3876. Good luck son.
Should we have a trouble ticket system? Yes, all we need is someone
with enough time to decide which to use, acquire it, install it,
learn it, and train everyone else how to use it. O.T. Guy won the
nomination.

RBNC.EHE - new image
WSNC -same
CMGA- same
CSTN/John got a new lantronix card and is working now, but is very gappy- still true
Every 13 min. 53 sec. there is a noise burst that raises the noise floor and knocks out our stuff. I'm
wondering if it could be a sideband from something. I listened and I couldn't hear anything but white
noise when it happens. I'm wondering if cavity filters and pre-amps will help.

Available generator power is about twice what we're currently using and what is proposed in the near term.
Balance between the 3 phases is roughly equal.
