• Calculation of power consumption and data room AC

  Hello

  Try to understand my energy consumption of servers in respect of the installation of a new AC unit and potentially adding a UPS battery pack. Certainly not I consider myself an electrician so I would value your input.

  I based my calculations this article where, in essence, the formula is: equipment BTU = total power for all equipment x 3.5

  Q: is it safe to assume that if a server has a dual power supply to double the power used?

  After digging by some docs of dell and random sites, I gathered the information following, and I don't know if it's the correct support :

  	Power double	Power in watts	Total power
  PowerEdge 850	None	345	345
  PowerEdge 1550	None	240	240
  PowerEdge 1750	Yes	320	640
  PowerEdge 1750	Yes	320	640
  PowerEdge 1850	Yes	550	1100
  PowerEdge 1850	Yes	550	1100
  PowerEdge 1850	None	550	550
  PowerEdge 1950	Yes	670	1340
  PowerEdge 2850	Yes	700	1400
  PowerEdge 2900	Yes	930	1860
  	Large total power:		9215
  	Required total BTU:		32252.5

  1 ton of cooling = 12K BTU about needing a 2.6-ton air-conditioning unit.

  That sounds right? Your thoughts?

  Certainly I'm not including the size of the room etc. but I wanted to just make sure that I am calculating the consumption of servers correctly. I also read that they start just numbers, and the number of disks in raid and memory sticks to the server will take more power... something that... is the addition of 10W by the disk/memory stick - it true?

  Thanks for your time!

  No, you must use the pliers on the individual wires, not more of 3 or 4 wire bundle to a cord. Better to find the track to the circuit breaker box, remove the cover and block it on one of the legs of the off circuit breaker. I would like to leave plug in for a day, exercise oversight for peak power consumption. You will need to get lighting consumption included in total and heat through wall, floor, ceiling, door gain.

• 580EX II eTTL full power using E - TTL FLASH off-camera cord

  With the help of a 5 d Mk III with 580EX II.  On the claw, eTTL works very well. Can access the menu camera very well.  When I join eTTL off-camera flash cord to get the Speedlites off camera, only full of works of power and compensation does not at all.  Full power only and can not access the settings in the menu of the device.  When I do the same thing to the 430EX II everything works very well on and off-camera with the same nine cord and menu is accessible and settings can be changed.

  No idea what it could be?

  This isn't a power cord Canon, it's Chinese. I think it's a combination of cord of low quality and reliable contacts on Speedlite flashes old guns. After I posted this question and had a cup of coffee, I tried again and magically it started working. I swapped the Speedlites and the 430 would not work, but then he slips and turns off several times it worked.

  I don't use my Speedlite flashes very often, but whenever I've done, it seems that I have trouble connecting with all that I use on the inclusion of the claw. I ETTL triggers that I always seem to have the same problem with.

  Maybe can anyone suggest a way to make more reliable contacts?

  The evidence is to try a Canon cord. Although bad contacts on flashes Speedlite is a possibility, the fact that these two of them only sporadically suggests that the cord is at fault. And since you rarely use the Speedlite flashes, you have probably not given time to contacts wear.

• CANON 70 D HAS NO POWER USING THE ADAPTER SECTOR OR 2 DIFFERENT BATTERIES

  I WAS USING THE CAMERA THE DAY BEFORE, I BOUGHT THIS CAMERA IN DECEMBER 2013. I USED THIS CAMERA VERY SLIGHTLY.

  TODAY, I WENT TO DOWNLOAD VIDEO FROM THE CAMERA TO CHANGE IT, BUT THE CAMERA WOULD NOT TURN USING THE A/C ADAPTER. I KNEW THAT NOTHING WAS WRONG WITH THE ADAPTER, BUT I PUT IN 2 DIFFERENT BATTERIES AFTER CHARING, THEM AND STILL NO POWER.

  I HAVE REPEATED TO TRY THE A/C ADAPTER AND BATTERIES. I TRIED TO TAKE THE CARD, THE LENS AND MAKING SURE THAT THERE NOTHING PREVENTS THE CONTACTS FOR THE A/C OR BATTERY.

  I STARTED SEARCHING ONLINE OF THE KNOWN FOR THE CANON 70 D ISSUES, I DIDN'T KNOW ANY SPECIFIC 70 D BUT I FOUND A FEW ISSUES FOR OTHER CAMERAS OF CANON WITH THE SAME QUESTION.

  SOME WERE TOLD TO TAKE THE CARD AND THE LENS AND REPLACE IT WITH ANOTHER GOAL, THEN PLACE THE CARD BACK, AND THEN ADD THE BATTERIES AND THAT WILL FIX THE PROBLEM. IT DOES NOT WORK. ANOTHER VIDEO THAT I FOUND SAID THAT THERE WAS A SCREW LOOSE ON THE CIRCUIT BOARD PRINTED FOR THIS OLDER CANON CAMERA... HIS SCREWS SEEMED TO BE MORE IMPORTANT THAN THE SCREWS THAT THE 70 D A SO IT WILL BE VERY HARD FOR ME TO FIND A SCREW DRIVER THAT SMALL... I HAVE TO GO BUY A KIT. BUT NOT RADIO IM LOOKING AT THE BOTTOM OF MY CAMERA IF TAKE APART WILL WORK, IT SEEMS THAT MY CAMERA BODY COMES OFF AS NOT EASILY THAN VIDEO.

  SO NOW IM STUCK WITH MANY PROJECTS VIDEO IM IN THE MIDDLE OF... BUT NOW I DON'T HAVE A CAMERA... I CAN'T AFFORD TO DO REPAIR, AND I CAN'T AFFORD TO BUY JUST ANOTHER CAMERA AND I'M NOT SURE IF THIS UNIT IS UNDER WARRANTY FROM CANON. I BOUGHT AT B & H PHOTO AND I STILL HAVE THE RECEIPT OF E-MAIL FROM THE PURCHASE.

  https://www.YouTube.com/watch?v=FYlNyZ1IP3s

  HAS ANYONE ELSE HAD THIS PROBLEM WITHT THE CANON 70 D?

  AFTER VIEWING THE VIDEO SHOWING THE SCREW CAME OUT ON THE MOTHERBOARD OF THE PC, NOW I SHAKE MY CAMERA, I THINK I CAN HEAR SOMETHING MOVING INSIDE... BUT IT COULD BE MY IMAGINATION. I'M NOT 100% SURE, I HEAR SOMETHING LOOSE. IT REALLY SUCKS BECAUSE I CAN'T COMPLETE MY PROJECTS AND I'VE FITTED THE CASE OF MONEY THE NEW LENS CAMERA AND PURCHASE HAS RECENTLY...

  IF YOU CAN NOT SAY THAT IT IS THE BATTERIES BECAUSE IM ALSO USING AN A/C ADAPTER. I KNOW HOW TO TURN ON THE CAMERA! IM GETTING NOTHING. NO POWER,

  I NEED HELP.

  I CORRECTED MY OWN QUESTION.

  WHAT WOULD HAVE COST ME HUNDREDS OF DOLLARS BY SENDING IT TO CANON, I MANAGED TO SOLVE THIS PROBLEM AND PERHAPS OTHERS HAVE HAD THE SAME PROBLEM AND THEY MAY HAVE SPENT MONEY UNNECESSARY. I SPENT ONLY $6 AND A FEW CHANGES... ALLOWS CALL HIM $7 TO SOLVE THIS PROBLEM.

  I DON'T HAVE TO DISASSEMBLE THE APPLIANCE BUT AS HE TRIED TO DO, I SAW SOMETHING THAT I SUSPECTED WAS THE QUESTION. I PLAYED A BIT WITH THIS SWITCH OR SOME TYPE OF CENSORSHIP OR LOCK.

  SOMETHING LIKE THIS WAS SO SIMPLE TO SOLVE, BUT COULD HAVE COST ALLOT ME OF MONEY. THE PART IS TOO DELICATE. NOW THAT I'M AWARE OF THIS, I CAN BE MORE CAREFUL, BECAUSE I WAS ALREADY VERY CAREFUL WITH ALL MY CANON... BUT IT WAS SOMETHING I WOULD HAVE NEVER EXPECTED THAT IS THE PROBLEM, I SAW THAT HOLE SOONER BUT NA NOT KNOWING WHAT IT WAS FOR... WHILE I WAS GETTING READY TO TAKE OFF THE BATTERY COVER, I NOTICED SHE HAD A TYPE OF CONNECTOR THAT WOULD GO IN THE HOLE (SQUARE) SO I SIMPLY PUT A PEN IN THE HOLE AND THERE IS A SWITCH OR SOMETHING, I PUT THE SWITCH IN THE CENTER. I PUT THE BATTERY IN THE CAMERA, AND THEN HE CAME.

• Calculation of Bill using SQL

  I've seen a few problems I'm trying to calculate the total amount for consumption. Thus, for example: for the first 20 watts is charged at 0,40 for next 20 watts is charged at 0.80 and 0.90 for each watt exceeding 20 watt

  I tried to do something on my own, but the calculation is wrong and is it possible to optimize the query because I don't want to do the math in the main select statement. subquery is a better option?

  SELECT CustName, previousRead, newRead, newRead-previousRead AS Consumption,
(((newRead-previousRead-100)*FR)+((newRead-previousRead-200)*SR)+((newRead-previousRead-200)/200)*TR)as TotalBill
  FROM (
   SELECT C.firstName||''||C.lastName as CustName, R.newReading previousRead,
  lead(R.newReading) OVER (PARTITION BY R.meterID ORDER BY R.dateVisited) AS newRead, B.firstconsumeRate as FR,
  B.secondconsumeRate as SR, B.firstconsumeRate as TR
   FROM reading R, address S, electricmeter W, customer C, rate A, corporaterate B
   WHERE W.electricmeterID= S . Electric meterID
AND R .electricmeterID = W .electricmeterID
AND A . rateID = S . rateID
AND B . rateID = A . rateID
AND C . CustomerID = S . CustomerID

AND r . datevisit < To_date ('31-07-2014','DD-MM-YYYY')
)where newRead is not null;

  Here you go, like what Frank said that you can do using CASE.

  SELECT Cust, previousRead, newRead newRead-previousRead AS consumption.

  CASE WHEN newRead-previousRead<=>

  THEN (newRead-previousRead) * EN

  WHEN newRead-previousRead<=>

  THEN 100 * FR + (100-previousRead-newRead) * SR

  WHEN newRead-previousRead > 200

  THEN 100 + 100 * EN * SR + ((newRead-previousRead)-200) * TR

  END as TotalBill

  DE)

  SELECT C.firstName | "| C.lastName as CustName, R.newReading previousRead,

  Lead (R.newReading) OVER (PARTITION BY R.electricmeterID ORDER BY R.dateVisit) LIKE newRead, B.firstconsumeRate like EN,.

  B.secondconsumeRate like B.thirdconsumeRate like TR, SR

  R reading, address meter W, S, rate A, company B, C client

  WHERE W.electricmeterID = S.electricmeterID

  AND R.electricmeterID = W.electricmeterID

  AND A.rateID = S.rateID

  AND B.rateID = A.rateID

  AND C.custID = S.custID

  AND C.custType = 'Corporate '.

  AND r.datevisit > = TO_DATE('01-06-2014','DD-MM-YYYY')

  AND r.datevisit<>

  ) where newRead is not null;

• Calculation of age using TimeStampDiff problems

  Hi, I'm running a strange problem. 'âge' is not an attribute stored in our data warehouse - but is "Date of birth".
  
  I try so to dynamically calculate age based on the difference between the date of birth and whatever "date statement" the user chooses. In the business layer, I defined the age as (note that field date_key on the date dimension is actually a DATE field, not the surrogate key):
  
  Try #1: TimeStampDiff (TSI_SQL_YEAR, birth_date, dim_date.date_key)
  Try #2: TimeStampDiff (TSI_SQL_MONTH, birth_date, dim_date.date_key) / 12
  Try #3: Truncate (TimeStampDiff (TSI_SQL_MONTH, birth_date, dim_date.date_key) / 12, 0)
  
  The problem I encounter is that, when written OBIEE the SQL in the Oracle database, instead of translating the TimeStampDiff function to use Oracle "months_between", it uses ROUND (months_between), like this:
  
  ROUND (MONTHS_BETWEEN (T48594. DIM_DATE_KEY, T48615. (BIRTH_DATE) / 12)
  
  And the problem is, when the flare, he pipes the calculation of age. For example, I get the following for an employee with a date of birth 20 October 1967:
  
  RPT Date Birthdate age
  Jan 2009 10/20/1967 41
  Feb 2009 10/20/1967 41

  Nov 2009 10/20/1967 42
  Dec 2009 10/20/1967 42
  
  As you can see, on 20 April, the age increased from 41 to 42 years. April 20 is exactly 6 months before date of actual birth of 20 October (so the problem with the ROUND function).
  
  I need to somehow "force" OBIEE use TRUNC (months_between), not ROUND (months_between). Well, to tell you the truth, not sure at all why he puts ROUND here... If I wanted the rounded number, I would add this feature in muself. Other creating a view in the physical layer to support this, is possible to do what I'm trying to do it directly in the business layer?
  
  Thanks in advance!
  Scott

  If so...

  use the functions of database directly with function evaluate in OBIEE

• Satellite Pro U300: Battery LED indicates low power using Linux

  Hello

  I have Satellite Pro U300 and I'm using Linux.
  I have a problem of opinion on my PC, it does not indicate that the battery is low (without flashing) and lights out.

  What this indicator a software driven or it's a hardware problem on my laptop?

  Another small problem that was Watch not remember brightness for battery mode.

  Thank you

  > I notice a problem on my PC, it does not indicate that the battery is low (without flashing) and lights out. What this indicator a software driven or it's a hardware problem on my laptop?
  > Another small problem that was Watch not remember brightness for battery mode.

  Please don't be angry with me, but first I would not talk about problems if you use Linux on the Toshiba laptop. Is that Linux is not supported and that's why some features of laptops may not work properly.

  About the light battery;
  The LEDs are controlled by the BIOS. As you know the laptop was running Vista and so the BIOS support for Vista.
  As I said above, if you use another OS like XP or possibly Linux so some features may not work properly.

• Calculation chart environment using collector, for an average

  Hello

  I was looking for a way to use a waveform graph, added the ability to set the width of the display of axis are all allowing a development of the chart track data, a little.  It is because the self-centering of the graph feature is choppy and does not allow users to zoom in or zoom out on the ground (which my colleagues have asked).

  It's basically my current solution posted here because I think that I finally got a right, but also because I know that you guys tell me: ten ways to do it better.  :%^)

  Note that the data here are slow; I think it would be really embarrassing if we looked at quickly changing data, although you could probably "Collect" more data and on average it all in the same way, to set the center of the axis y of the graph.

  

  The front panel; I put in place the three graphs in a tab control.  (Of course, there are no signals on the data acquisition module, when I did; but at least zero focuses on auto, and the range control works).

  

  I guess I'm especially looking for your comments and I was wondering if I missed an obvious way to simplify this process.

  Thank you

  Danielle

  Hey Danielle,

  Given that it is a long-term test, are you interested displays all the data of your test or only the most recent game? The waveform table allows to memorize and display historical information because it has a buffer associated with it. From your code, it seems that this collector is just used to store information so that you can average the last few data points. The only thing I see standing in your way of simply with an average of your data is that it seems that you display two signals on the graph. So which signal you want to be centered? If you have a signal you want to reach on average to get the center of your chart, you may son of this signal in a convert from Dynamic Data VI express. When you put everything first down, a configuration window appears. You can then select ' 1 D array of scalars"as the type to convert. The output of this VI will then be an array of data points. You can then use the VI means to find the way to this table 1 d.

• Samsung PC battery problem because it won't turn up until turn on the power using the main power source (no battery))

  Hello to all, pls, I bought a Samsung ATIV smart PC end of July and I just discovered yesterday that he did not come again. Then I plugged to a power source and tried again and he came and saw plugged not charging on the battery bar and the battery percentage was 94. When I tried to remove the loader system just went of and would not come until I plug it into a power source. Please someone idea about what to do. Thank you

  This means that the charging system is physically broken, call Samsung for a repair or replacement time.

• Problem with calculation of measurement using instruction box

  Hello Experts
  
  I have a measure that calculates the percent of sales by State - "sale by States" / "Total sales" * 100 and the requirement is when the numerator of the measure is < 11 then it should be ' *'. I tried to write a next case statement case when sales by State < 11 THEN ' *' ELSE sales by State END / "Total sales" * 100. I get an error saying incompatibility of data type of ideas how I can make it work.

  Hi RC,.

  I used to have the same than the one that I solved it using the following statement hope, that it will aid.

  BOX WHEN ((ARRAY. NUMERATORCOLUMN< 11))="" then="" '*'="" else="" concat(cast(round((((numerator="" column)/(denominator="" column))*100),1)="" as="" char(50)),'%')="">

  Here the results of instruction box in the two values is * Alternatively, value (which is stored as varchar instead of the number data type).
  Have, so the results are varchar. you get no data type mismatch error.

  That, by your statement the case... A case get varchar and another survey number which is the offset. (Logic)

  I have concatenated with the '%' sign to show results under 15%, 16% and stores the same results (Varchar).

  I hope that this solves your problem. Please, attribute points. :) :)

  Let me know, if you still find problems.

  RC,

  It is always useful in the forum when you post your code and the associated error. Of what you provided; It seems that your case statement is missing from the end clause and it should look like this:

  SELECT CASE
            WHEN sales_per_state < 11 THEN 0
            ELSE sales_per_state / "Total Sales" * 100
