    Sun Fire X2200 M2

    So I got a Sun X2200 M2 a month ago, and did my usual run of redoing the thermal compound on it, de-dustifying it, etc. and have been successfully running it for a month on and off, and more-so after finding and updating the BIOS and ELOM firmware on it.

    So a couple weeks ago, I pulled the second CPU's heatsink and re-repasted it since it was running warmer than the other CPU. (doing this solved the problem.) while doing this, I saw something I didn't see before... one of the capacitors next to the CPU socket UNDER the heatsink had pooped its pants! when I saw it, it made me think of my recent bout with my Ultra 10... which had a few that did the same thing. all the other capacitors on the board (attached) look fairly clean. and yes, that is 64GB of RAM in there as well.

    I picked up a lot of 10 of them off eBay because I'm broke and couldn't locate proper replacements on mouser or digikey for the life of me. I got some Panasonic FL 4v 680uF, same voltage and rating. however, today I learned they're new-old-stock from 2005, november and december. serves me right.

    I have some friends coming from Ohio in a few days and one of them is bringing an ESR meter for testing them all... but I really want to just get the darn thing replaced and done with. my goal is to put this in a rack in California owned by my friend in a Datacenter where he will likely pay almost nothing more to have it in there-- and in which case would be good for me!

    My question is, do I go ahead and do the deed of replacing them outright or do I wait for an ESR meter to become available to me to test them out first?
    I'll be gone in Ohio for the next week after that and would rather have a fully 100% server than one with a blown cap on one of the CPUs. Also, do I use one of the older ones, or one of the newest of the lot of them? in practice I understand it's sketchy to use old-stock caps from talking with people that've done electronics repair for a living, but supposedly okay in some sort of way if the cap tests out good... so I'm not too fazed by them being NOS to an extent.

    --
    TL;DR bad cap in sun amd64 1U server, no replacements on Digikey/Mouser, got replacements from eBay because I'm broke, found out they're legit 10 year-old NOS, do I wait for my friends with an ESR meter to test them or do I just go ahead and wing it?

    Is it possible to test small ceramic disc capacitor with analogue meter?
    by chth96
    I read EBOOK of Testing Electronic Component and found that

    "In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
    Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
    It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

    Is it really possible to test small ceramic disc capacitor with analogue...

    Modification of a Fluke multi meter that uses three AA batteries to use a 14500 lithium ion battery
    by sam_sam_sam
    I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board

    I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery...

    Changing the scale of an analog meter
    by jorpec
    Hi

    I want to change the scale of an analog meter, to monitor the charge of an li-ion single cell, so the needle at the end would point 4.2 volts and the 0 on the meter would point 2.5 volts or so, i tried to add diodes or a zener in series with the meter but the changes of the ambient temperature also changes the voltage value on the meter
    I wonder how i can accomplish this so the meter would be precise at any temperature ?

    How an incandescent light and a ESR meter ** friend**have a machine blowing fuses
    by sam_sam_sam
    About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well

    Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for

    Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the ā€œEā€ stops and one switching power (24 volt) supply and a transformer...

    EDMI ATLAS MK10 Electronic Meter Discussion
    by Stephan Mathers
    Greetings, new guy here but always interested in the crazy universe of modding

    We just finished construction of around 25 vacation houses, all inside the same private area.
    Each house has 3phase power , and we bought an atlas MK10 meter for each house (25 meters total ! )

    The metering on a per-house basis is done privately. Its not done by a utility company. The utility company will only charge us for the total consumption of all 25 houses together.

    Id like to do a small modification on the firmware of our MK10 to make it easier identify each house's...
