Will ask the DC engineers to take some pics when they replace it. 4 CCR's purchased (over a period of 2 years), this is now the 3rd one failingHi Chris,
Let us know if the C10 capacitor is leaking, and if it has the black plastic around it.
It's nearly always about heat. Heat has an extreme aging effect on electrolytic capacitors. When a particular value capacitor in a device fails it's mostly the ones closest to the heat.I wonder if the cap failures are due to low quality capacitors, or poor circuit design..
Well the COST associated with a RMA is a factor. The DISTRIBUTORS just pull up their shoulders (frankly, I was forced to purchase my first replacement PSU from MT directly, as the DISTRIBUTOR insisted that replacement PSUs doesn't exist and can't be replaced. My second PSU was imported, for the same reason). Talk about DISTRIBUTORS being uneducated.I am seeing wider reports of CCR power supply problems now.
Mikrotik, maybe you are not seeing these problems via RMA as the units are 12+ months old, or people are just replacing the PSU and not returning the routers.
Same there, cooled DC, 1036-8G-2S+, 1y6m, C10 capacitor in PSU is blown up. Voltage - 23.9 without load, step down to 23.3 when starting. Switching CPU freq to 800 (within bootloader) helps starting it up. On full freq - cyclic reboot.The one I'm replacing right now is 1y 6m old and was installed in a data center. Monitoring shows the 1036 has been running at a nice even temperature.
Is there any way for a distributor to tell if they have the fixed version? I'm looking to deploy my first CCR1036 soon and as I won't be on site, this thread has me very worried if / when the power supply fails...As far as I know, the last 6-8 months we are shipping units with an improved PSU, the C10 has been changed to a better one. Some parts have been changed to better handle the heating.
As far as I am aware, my failed PSU posted right at the top with the greenish capacitors, IS the improved version. Black caps are the old version. Improved version, is ALSO failingIs there any way for a distributor to tell if they have the fixed version?

Pretty easy. The one I pictured above was swapped by a non technical user. Only gotcha to remember is the screws closest to the back are longer, and remember to screw through the earth lug.Also how easy is the power supply to replace for a non-technical user if I just ship a bunch of spares?
Does your re-sellers KNOW that replacement PSUs even exist? Again, see my comment(s) above which you so nicely ignored. We are being told by your OFFICIAL DISTRIBUTORS that the PSU *CAN NOT* be replaced because it is internal. According to them, a replacement PSU does not exist. That to me, is the cherry on the cake through this entire ordeal...Contact the seller for warranty options, just like with any hardware issue.What will you offer to people having 1036 with the old design suffering on this problems?
Read my post(s) again. I have not ONCE talked about warranty. I am asking you, specifically, about REPLACEMENT PSUs... In other words, *spare parts*If your seller provides no warranty, you can either replace the cap, like others posted above. To prolong the life of the cap, you can set the FAN mode to "redundant" which increases fan speed and brings temperature down by at least 3 degrees celsius. You can also mount the device in some other way to improve airflow.
Maybe in cases like this (user-replacible part that fails sort of frequently) it would be a good idea to offer it separately as a catalog itemDistributors are different. Some provide the best price, some provide the best customer service and attitude. Choice is up to you.
Not touching of warranty and suppliers... I can not use 1036 router in my work now - his PSU too hot and unreliable. Yes, i know that it can be replaced, and i already bought two spare PSU, but this CCR should be stand in far datacenter, and in case of PSU fail i will lose too many time for replace it. I did wanted to replace my RB1100AHx2 by the CCR1036-12G-4S, but after testing and reading this forum I see that i can not do it. We see that older RB1100AHx2 (and now newer but cheaper RB1100AHx4, with two not hot PSU) will be more reliable than newer and more expensive CCR!It is available as a separate part for purchase, but you have to check with our sales department. I think the part is only available to distributors, they sometimes sell it to people where warranty has ended.
How to set the FAN mode to "redundant" ?If your seller provides no warranty, you can either replace the cap, like others posted above.

You can also mount the device in some other way to improve airflow.
Yes, CCR1036-12G-4S failing. Unless I'm mistaken, both are single PSU devices. They should use the same power supply.Has anyone the same problem with CCR1036-12G-4S? Or is just a CCR1036-8G-2S+ problem? Does they have the same PSU?
The main problem of these PSUs is the high load for CCR1036 and high temperature in result. You can see in pictures in this theme that green capacitors swells up same as black. I changed these capacitors to low ESR aluminum polymer capacitors such as 397AVG035MGBJ. They works long time and not swells.Thank you very much.
So we assume that if I buy tomorrow one CCR1036 I can get the "revised" version with green caps, and the connector for the 2nd PSU.
Hi Mr mkx.Capacitors are the two black cylindric elements with metal-exposed tops. The one farther from wires (right one on first attached photo) looks suspiciously bloated. If you can find somebody with soldering skills, have both of them replaced with new ones of same capacity.
Well, they can be monitored via SNMP so when one of them fails you can plan downtime at a convenient momentI don't understand the logic behind dual PSU's that aren't hot-swappable.
Some week ago, we replaced ALSO a PSU r2.... Mikrotik, please make more attention oh details!I have lots of ccr 1036 12 g 2s first version
Every unit has minimum one PSU changed. Now I change the capacitors myself even the new psu s with green capacitors blow up in relative short time.
Yesterday I took 2 router out of service with blown up capacitors on the routerbord. Will replace them.
Strange thing on one unit CPU temperature went up to 83 degree Celsius. I can see that issues start when voltage is not constant and fans running maximum speed. The units are all hosted in a carrier grade datacenter.
MikroTik needs to provide better power supplies and stop using that cheap capacitors.
