Tech Staff Meeting Notes July 19, 2010
The top priority is always repair of down stations.
NM problem stations
ET problem stations
NetOpsV will be focused on AQMS on November 3 and 4 in Menlo Park.
Many stations were repaired over the the past six weeks.

Node reset instructions are at
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 node went down friday morning 7/16. Notes from Jim:
Chris is checking on the cost of a service contract for the generator.
The DBB is currently stable and there is a second computer at lnxt on the dsl. Its second ethernet on the 10.156 is currently disabled.
Need alternate comm path. Telecom says dsl isn't available (though we once had ISDN).
AZTN: Upgrade PC and replace XLAK clock
Need to gather up a contact list (e.g. everyone's home phone, power companies, etc) and put it on webworm (password protected). Jim has a draft of this that so far has all the node contacts. Mitch suggested that the umdrive seisnet space might be a better place than webworm for it.
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 possibly by September 1. John will need to give Phillip Crotwell a show and tell at each station. 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 lost track of what stations need what part of the yr3 upgrade. Based on a recent email from Jim we have these stations waiting completion:
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.
There was a very successful trip under the bridge on April 13. Jim reported:
We got six recorders back online, had to pull #5 due to a hard drive failure. Of all the options I think I like this the best. It looks like we can get a DC powered "industrial" (-40 to 80 deg. C) 4 port switch which supports TX/RX multimode fiber w/ ST connectors for around $200. I'll look into it further tomorrow.
Recorder #5 has a bad ide controller and needs to go back to PMD for repair. Unfortunately there is no budget to get this repaired. Steve will try to get a ballpark estimate of the cost so Mitch can ask Sharam what he wants to do.
Recorder #7 needs a site visit to correct a non-fatal error in the bat file.
It isn't realistic to move the antennas so we're not likely to significantly improve the telemetry under the current circumstances. The part that causes the problems though are not the recorders but the ringbuf program. This pulls data using the netbui remote mounts into a buffer on the windows 98 box at aztn. Note that this is not really a proxy for a real-time feed and never has been. And we don't really need continuous data. We can pull data as needed from the recorders when there's an event. And instead of Al sinking enormous time and frustration into keeping ringbuf going, he can instead just download 15 minute (or some several minute time segment) at regular intervals (say once per month or week) to verify that its working. Steve and Al are working out this new procedure.
We also discussed the need to have the data vetted. No qualified structural engineer, to Mitch's knowledge, has looked at bridge data and verified that its good. Mitch processed a day of continuous data that Steve saved on October 27, 2005 (/gaia/home/mwithers/Projects/I40Bridge/hdbr/segy/20051027). The instrument response was removed, data were converted to segy, and a gzipped tar ball is available. Mitch looked at it and it looks reasonable but it should still be vetted by a structural engineer who knows what to look for.
Bad CMG5 E/W.
Not getting broadband feed.
Replace two bad mss100's.
Bad 100' accelerometer.
FPAL is happier since the upgrade to a Ref Tek, Trillium and Episensor. It is staying 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.
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.
Many of the NC station problems are probably because of insufficient power. John will find out what's needed to increase solar and battery to help make it through the winter storms. The ET stations have the same issues but problems are not as evident because they are, in general, at much lower elevation (less snow). CMGA has had a power upgrade to two 100 aH batteries and a 64W solar panel. Other stations in need of power upgrade are: TVNC, GFM, RBNC and TRYN.
GFM The NC state park service is purchasing GFM. We already have a couple permissions from them and John initiated the paperwork for the GFM permission.
TRYN: the forest service wants to remove the tower. There will be a new 180' tower and we have permission to be on it. We also have permission to be in the building (rack mount only). They want this complete before winter.
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.
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. James will attempt to detail when the problems occurr to see if that correlates with operation of the other installation.
CVMS has a new NetR8 receiver and its working well. James enabled a utility to make getting receiver status easier and rewrote his scripts to parse the output into html. There are now separate scripts running for netRS and NetR8.
MAIR had a heat problem James fixed with an additional heat sink and new power supply.
Most monuments need a new paint job and weed control.
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.
Radio purchase is out for bid. Likely won't have radios until mid-July. Most other items are in hand or on order.
Rough-ins complete for HBAR and PENM.
GNAR needs a custom cabinet on stilts. Can also remove the computer and put both GSAR and GNAR behind a router pulled directly into scream and rtpd at ceri.
SWET is scheduled for next week. Not sure yet whether we can get on internet at the top of the bell tower or the bottom. Regardless the pc can be returned to CERI and the data will be pulled directly into rptd. The kiosk will use rtdisplay to connect to rtpm on hector.
Need to test rtpd on wintel. Scream/scream2ew will be replaced with rtpd/reft2ew.
Michelle created a blanket TA for ARRA travel.
We are approved for the following in approximately the same order as we
hope to complete them:
Note that using other funds, we're also upgrading 3 additional ET stations to digital with episensor and FPAL to the same hardware as the other broadbands.
Mitch hung a chart in the war room to track our progress (we're required to make quarterly progress reports and to meet the proposed schedule).
We need to be very careful to keep AG, ARRA, and CERI hardware separate and be certain that hardware purchased by each project goes only to that project.
All replaced DM24's and CMG40T's are to go to south campus and taken off inventory. This hardware is not to be redeployed anywhere in the CERI seismic network nor FDL. Mitch is checking whether they can be donated to Bob's Argentinian colleagues.
Two CMG6TD's are at guralp depot in Menlo for repair.
Need to review power loads and line balance after adding the new AQMS servers. Review needs to consider addition of new landmark servers, mac server, and seisnet deep waveform buffers. The Earth Science Library (ESL) in 3892 is moving to the main branch and has a liebert. We should consider carving out rack space in that room (though backup power is an issue).
We're now officially providing maintenance support for NSMP stations in the NMSZ area. There are 22 stations. SLU has 11 to the north and CERI has 11 in AR and TN. They are all dial-up K2 or Etna. Data continue to go to NSMP in Menlo who will continue to monitor SOH. They will email or call when there is a problem. We're the boots on the ground.
NSMP Station List.
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.
ISTI was contracted by USGS to support INV. John will work with them to get initiall dataless SEED going. John will be our INV czar.
What to do with the Steiner brain dump DVD's?
Mitch made a seisnet group on umdrive. Go to http://umdrive.memphis.edu/mwithers/seisnet You will need your uuid and password. There are several things on there including John's database. We can put contact info there too when its available. Only people in the seisnet group have access to this area. If you download something for update, don't forget to upload it again so that we all have the same version of the files.
There is now a ceri_seis email group that includes all the seismic networks staff.
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.
Chris continues to hound the supply to try to get Parker's old Suburban onto govdeals.
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?
