CCR1036 Power Supply

Wed Mar 15, 2017 9:48 pm

Hi,

Someone close to the Netherlands that can supply a CCR1036 power supply, urgently?

Just had ANOTHER CCR starting to fall over due to a suspected failed power supply, shrugs... :(
Regards,
Chris

And there she goes... :(

Found a replacement at a online shop in Germany that luckily has stock. Hopefully I'll receive it tomorrow!

MT - you REALLY need to work on the reliability of your hardware :evil:

Hi Chris,

Let us know if the C10 capacitor is leaking, and if it has the black plastic around it.

Thanks,


Andrew

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 failing :-(

I guess we found the issue. New PSU is in, 23.7V on the dot just like it used to be.

Hey, I'd be grateful if you could name the shop you got a replacement power supply from as I need to replace two of them myself and my distributor knows of no such thing.

http://www.meconet.de/ in Germany, ~14 in stock if I remember correctly. I also saw a few US companies with stock (but shipping & customs would have taken too long in my case).

My first unit came from MT directly, but I think that was on a special case only.

BTW @nz_monkey...

These power supplies with the better, green caps.. Aren't these supposed to be the NEW improved power supplies?

And yes, this is in a huge DC, so a very stable supply on the AC side, on UPS.

Hi Chris,

Yep the PSU with the green capacitors are the revised ones.

You have me really concerned now :(

I wonder if the cap failures are due to low quality capacitors, or poor circuit design..

Currently described problem seems to be specific power supply issue.
For the last 4 months none of RMA CCRs was returned due to problems with power supply, neither we have received any other request about faulty supply.

I have two routers CCR1036-8G-2S+ and both have failed psu.
And yes, the C10 capacitor fails.

I can't do RMA, becouse warranty was over a year ago.

For one router, I changed the power supply from the LED strip. It has a power of 100Watt.

For the second (backup) router, I replaced both capacitors (C10 and C11).

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.

Fig 2.15 shows the extreme reduction in life caused be elevated temperatures.

@jebz

I don't disagree. The PSU in the CCR1009-1036 receives no airflow so if anything was going to overheat, it would be the PSU. Coincidentally the cap that seems to fail is C10 which is closest to the heatsink.

Our units that have failed are in Tier3+ facilities with clean power and excellent cooling, so it does not seem to be directly related to external environmental factors.

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.

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.

If it's THAT big of an issue to JUST get a replacement PSU, just THINK about what the issues would be with a RMA though the DISTRIBUTOR. Seeing the DISTRIBUTOR doesn't want to assist, it becomes financially unfeasible to bother to do a RMA to begin with. Why would I spend how many hundreds of $ on courier charges to send a faulty unit back to MT, if I can just go and purchase a replacement PSU for $15 odd? Having a CCR fail in a production network, there's the matter that it is a time critical failure too. You want to get back up and running ASAP. You don't have the TIME to spend weeks and weeks on RMA procedures and wait while distributors and/or MT plays games and sit and think about what could possibly have caused the failure.

MT is sorely unaware of these issues because of the lack of RMAs received (due to their distribution channels), the problem is FAR greater than what MT would like to accept. MT's distributors (in SA at least), is a joke, to say the least.

Matters like this, faulty hardware, unreliable hardware, distributors pulling up their shoulders not assisting clients... These are all SERIOUS concerns, which for me personally, is making me think very long and very hard whether I want MT in core production networks.

Just my 2c.

We also had 3 failed CCR PSU within the last 12 months. All Units are located in a datacenter with controlled temperature without overheating. We replaced the PSU with spare parts and never notified MT about it as the CCR were out of support.

The third PSU died last friday and it seems like it killed the CCR as well as since then VRRP with AH starts to fail 1-6 hours after activating it (the message is saying that the AH encryption is wrong).
The VRRP config was running fine for 2 years without changes and this error occurs randomly after enabling the ccr.
VRRP is behaving normally, both nodes see each others and failover can be done by changing priority without problems, until suddenly, between 1 and 6 hours after enabling, the ccr with the failed PSU messes up the vrrp ah config and both units decides to become master.

Its really bad that a failed PSU can damage the CCR and makes him act that bad. We disabled VRRP for now and will remove all CCR from our core network and use them only in non critical environments. We are really sad about that as we really like our CCR but it looks like they are not ready for critical environments yet.

Re: CCR1036 Power Supply

We started widely deploying 1036s about 3 years ago and less than 2 years in we started seeing some fail. Now after 3 years with a couple hundred deployed its become a big issue for us. In fact I'm waiting for a tech to run out and replace a power supply of a down CCR right now. We have a handful of these power supplies on hand but the outages caused by them are killing us. 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. The max it ever hit was 59C on the CPU and 55C on the chassis. With the average being only 43C on the chassis. MikroTik says its tested up to 60C.

I'm glad to hear they've at least made some changes to the newer power supplies but I'm still nervous. Has anyone tried the 1009s with passive cooling and external power supply?

Thanks

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.

Same situation here in Belgium.

A few CCR1036 in production (bought from Interprojekt).
C10 blown after a bit more than 1 year of 5 of them.

Distributor has changed the power supplies with better ones for 4 of them.
The 5th one was blown last week. We'll change the power supply on all the remaining devices.

I would be glad to know if other models have the same power supply, to change them all.

When it is so clear what is wrong (as usually with SMPS), why don't you replace only the caps instead of the whole PS?
On this type of board and with this kind of cap that should be easy to do for any electronics repair person.
One year is too short a lifetime, but those caps are going to be the first thing that fails in most of today's equipment.

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.

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...

Chris

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.

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.

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!

Re: CCR1036 Power Supply

Fri Sep 01, 2017 2:05 am

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+
Image

CCR1072-1G-8S+
Image

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.

My power supply died about 9 months ago and I still cannot find a replacement... thinking of building my own... just bought a new piece but MT should offer premium power supply replacements for sale here in 'Merica.

Has anyone the same problem with CCR1036-12G-4S? Or is just a CCR1036-8G-2S+ problem? Does they have the same PSU?

Yes, CCR1036-12G-4S failing. Unless I'm mistaken, both are single PSU devices. They should use the same power supply.

We've also had two or more CCR1036 power supply failures. The last one that failed has the green capacitors.

Has anyone found a source for a direct replacement power supply? Prefer for the replacement to drop in just as original power supply does.

Thanks,

Brad

Bad caps in a power supply are repairable. When you cannot do it yourself, it should be possible to find a repairshop that
can do it for you. That would probably be quicker and cheaper than hunting down the same power supply.

I'm confident in my soldering abilities to replace caps etc, but sometimes time runs short and simply ordering a complete drop in replacement and moving onto the next project is more enticing!

I'm betting mouser.com has a supply that will work, but want one that drops right in place without modifications.

Guess I'll order the caps in case I never find the replacement supply.

MikroTik; Can you provide a link to where a replacement supply can be purchased?

Thanks,

Brad

Hello
Just to understand correctly:

the "old" CCR1036 (all versions) had black capacitors.
The "revised" CCR1036 (all versiones) have green capacitors.

What about the "new" 1036 ? has not been announced yet, right?

How can I know if the CCR I am about to buy new, is the old or the revised one? Do they have any markings, or serials?

There is no "new model" or "new type", it is just the changes between production runs that you find in all equipment.
Probably it is possible to derive it from the serial number, but that kind of information usually isn't public.
However when you buy from a distributor with normal stock and turnover you would usually get the latest models all the time.
(they don't stock these things for a year)

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.

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.

Hi All

The current PSU condition is like this

If I replace with another brand with 24v 2.5a power can work well.?

Because I have trouble finding the capacitor.

Thanks,

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.

Is this PSU issue still a problem when buying new CCR-1036 units or has this now been resolved?

Just had one of our CCR1036-12G-4S start rebooting and having trouble starting up. It's a number of years old and it's the first issue we have seen. We had a standby CCR1036-12G-4S just in case.
Now without a load it seems to be running so I'm able to compare the voltage that is shown by each router. Perhaps this is a way one can detect a failing unit if the voltage is dropping.
Screen Shot 2019-02-10 at 8.17.50 PM.png
Notice the bad router on the left has a voltage of 13.9V compared to the good router on the right of 24.2V

If I just replace the power supply will the bad router be back to 100%? Could the failing power supply have damaged the router board?

It will be fine when you repair or replace the power supply.
(just the electrolytic caps need to be replaced)

I don't understand the logic behind dual PSU's that aren't hot-swappable.

Well, they can be monitored via SNMP so when one of them fails you can plan downtime at a convenient moment
to swap the entire router or to repair it using a spare supply.
