laugh life to this blog.
The patient now is a curious device Apple, the Time Capsule, 500GB version.
E 'hardware that integrates several peripherals, all in accordance with the philosophy of course Apple. The attacks plug and it works. As you say Steve Jobs.
contains within it: a 802.11n WiFi router, switch, 3-port Gigabit, a 500GB hard drive and a USB printer because x is also able to act as a Print Server.
has functions of NAS users and extends the functionality of Apple's Time Machine automatic backup on the external drive.
But Nobody's perfect. Apple in its style exercises can make big mistakes.
WARNING!
THE TC HAS INSIDE THE POWER SUPPLY, HIGH VOLTAGES ARE PRESENT. IF YOU HAVE NOT FAMILIAR WITH NOT TAKE ON ELECTRONIC TRANSACTIONS chance. VI DO EVIL!!
The Time Capsule arrived in the laboratory (!) Turns off during boot. The faceplate, which during the boot is amber and turns green when fully operational, after about 10 seconds off.
are opening the TC.
the deceased.
The vines are beginning to appear.
No screws visible. The screws are under the rubber base
rubber base completely removed
If you proceed with care and do not touch too much or the rubberized base, nor the metal surface, the sticky residue will be sufficient to close the TC.
The order and treatment are within the highest levels. Maybe too ...
Removed 10 small screws with a screwdriver you can remove the metal base. You can put away the screwdriver for now, will only close to everything once you have finished.
The connector of the ventilation fan.
... taking care not to rip the connector of the fan!
shall then remove the hard drive and power connectors to the logic board.
Removing power connectors. That logic board has a hook that goes up a bit.
To remove the hard drive you must remove the temperature sensor linked to it.
The sensor disconnected from the HD is connected to. It 's a 2N3904 transistor.
Once removed the connectors (power and temperature sensor) power supply, because of the failure of the TC, is removed with ease.
The power supply is surrounded by a rigid plastic, resistant to high temperatures. Proceed with a sharp knife, gently, to "reject" the power
"Face" of ALI.
Remove the rest of the cover is quite delicate, as it is glued to the wing with a kind of hard to remove sticky gum. It 'important to preserve the envelope because cracks can cause the failure of the power supply from the logic board and insulation from the base metal with melting of the TC ...
The method used by me for the opening of the wing is one of the "butcher". Widen the envelope a little at a time by progressive cuts with sharp knife between the plastic and glue. How do the butchers when slicing the meat:) We hear some crack somewhere in the shell is broken, but I can ALMOST keep it healthy.
feeder discarded. The plastic is still in good condition.
WARNING!
AT THIS POINT YOU MUST BE VERY CAREFUL. TWO BIG BLACKS INPUT CAPACITORS WING LADEN AND 'NEED TO DOWNLOAD THEM BEFORE YOU GO ON
Half an hour after unplugging the TC from the wall there are still almost 300V!! To download the capacitors have a resistance of 0.47 Ohm/5Watt using the shell. Other figures are well, that I had on hand ... The important thing is to download the capacitors (actually just download one, the one with the leads + easily accessible). In extreme cases you can short-circuit the capacitor. It is not advisable, however, could destroy the excessive stress.
Downloading ...
Once secured the alimentaore visually inspect the capacitors on the low voltage side:
this side seem in good condition. The capacitor C5 is highlighted in red
obviously swollen.
found the problem. At least one of the low-voltage capacitors is seriously damaged. And even they were of poor quality components. The capacitors used are RUBYCON SAMXON and of excellent quality. The problem is the heat dissipation. The plastic construction does not help the TC, the gum base is a poor conductor of heat and ventilation fan, silent ring can not dissipate the heat generated by the TC through the small slits on the side of a metal base.
Outcome: The CT scan after a little break. On http://timecapsuledead.org is the log with the statistics and the duration average of a TC. 18 months and 20 days. Despite
other capacitors appear in good condition, I decided to replace them all, since the protective plastic will not hold a second open ...
Shopping List: 2
Capacitors Capacitor 330uF/35V
1500uF/6.3V
1 1 1 Capacitor Capacitor 470uF/16V
470uF/6.3V
When you go to buy new capacitors bring old as sample sizes are rather critical and verify that the components are of excellent quality and come in place of old.
With my provider I had a problem with the capacitor voltages: I took them with higher operating voltages, should not create problems.
Remove the old capacitor has a few mange. The two small green can be 470UF desoldering, but the pond is used to make lead-free wings, who has used it knows how mangy having to meddle.
The other three leads, but have dipped into that lousy gray rubber. I preferred to cut the base terminals of the capacitors with wire cutters and use them to link the new.
The five culprits removed. In reality, the blame lies with people who make them work in 400 °!
It 'goes without saying that the electrolytic capacitors are polarized, and then met polarity. If you are not there any signs used my photos as reference. You can find references to the negative even on the PCB.
The new capacitors in place. I am a little older, but they enter the perimeter of ALI.
is then, with the utmost caution, to reincarto supply. The more you plan and less plastic will break ...
reassembling the drive I noticed that Apple keeps its promises. As in advertising on your site within the disc is a class server. Exactly a Barracuda ES, with reliability indices higher and higher fault tolerance and high temperatures.
Some others have found, however, the desktop class drives ....
You then remount the power supply, connect the power and data connectors to the logic board and HD, it hangs up the (useless) fan, and if all went well:
Light ( green) was.
If you want to do the performance tests of the power supply alone is necessary to connect a load, otherwise it will not start. In fact, I think Waits some consensus from the logic board. Paying attention can try to start it all without connecting to close the TC.
This is the guide. I will not have problems on average for the next 18 months and 20 days.
