Another one bites the dust:
This one was in a Tier4 datacentre.
That makes it 100% of all CCR1036-8G-2S+ that we have purchased have now experienced this fault.
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 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 failing 
Well that’s not very reassuring I’m sure there are many other 24V 4A power supplies out there that are more reliable, just wondering about compatibility with the cable to the CCR. Has anyone tried this?
Also how easy is the power supply to replace for a non-technical user if I just ship a bunch of spares?
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.
They will only need to take a PH1 and PH2 screwdriver and the replacement PSU.
You are right that heat causes this issue. We have already upgraded the parts in newer revisions of this model, this is the first CCR design after all. New CCR models have other designs and do not suffer from heat anymore. We do plan to release a replacement 1036 in near future, where the PSU design is already completely different and does not suffer from heat problems.
What will you offer to people having 1036 with the old design suffering on this problems?
Contact the seller for warranty options, just like with any hardware issue.
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…
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.
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
Replacement, warranty and any other service is up to the seller. Each distributor has their own strategy and you are free to select the company that provides the best service. We provide warranty services to all distributors, but what services they offer the end user is entirely up to them.
If the device is under warranty, we will even ship a new PSU to the distributor, without having to return anything to us.
Distributors are different. Some provide the best price, some provide the best customer service and attitude. Choice is up to you.
Thank you for the response Normis.
In my non-expert opinion, turning on redundant fans may cool the CPU by an extra 3degrees, but the fans are ducted so only draw air from the front of the CCR over the CPU and out the back.
I would be very surprised if this made any difference to the operating temperature of the PSU.
It is great to hear a revised 1036 is about to be released. I look forward to seeing the new design.
The -3c reduction was measured on the PSU.
If removing wind tunnel, further -1c drop was observed, but CPU temp increased +5c.
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 item
just like the hot-swappable and external supplies, so a customer can order it separately after finding out that the distributor where he bought
the router previously is not too helpful, out of business, or whatever.
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.
We do plan to release a replacement 1036 in near future
Is this a possibility before 2018? As someone about to buy my first CCR1036 I’d prefer to avoid the model that’s about to be EOL, but I need it before the end of the year.
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!
To highlight the problem with the CCR1036, the following screenshots are from two routers that are installed 1U apart from each other in the same rack, in a Tier4 datacentre:
CCR1036-8G-2S+
CCR1072-1G-8S+
Note the huge difference in temperature. The CCR1072 board temp is 29degrees, the CCR1036 is 41degrees. Thats a 12degree difference just due to the PSU heat being trapped in the CCR1036.
I am glad Mikrotik have identified the problem and fixed it in newer products. Once the “new” CCR1036 is available we will replace all of our CCR1036’s with them. The outages cost us far more than new routers
I guess I’ll be going with the revised CCR1009 then and hope its fast enough for all the queues I want to use. Judging by this thread it looks like the CCR1036 will overheat and die on me since it won’t be installed in some datacenter with super low ambient temperatures.
