hi,

we got a RB600 for testing and have some problems which seem to be temperature related. the RB works fine on the bench without much load and only configuring via winbox or terminal. as soon as i put it in an operation environment and use 3 radios and 1 ethernet port with a total throughput of about 15-20 mbit/s i get sudden reboots every 5 minutes. after trying different power supply's and different voltages and also trying POE rather than power jack i have reduced the cpu to 266MHz. i got an uptime of about 10 minutes and then sudden reboot. next step was then to open the original RB600 indoor case and putting a fan beside it. i now got uptimes of about 30 minutes before it would just reboot. i have tried ROS 3.1, 3.2 and 3.3. the version makes no difference.

does anybody have similar experience with the RB600 ? how the hell can it be made stable ?

radios in use are 4 R52 if which one is disabled. case as mentioned before the original RB600 indoor case.

Just Mount a cooler on the heatsink and one for cold air from outside the box and see what will hapen...

well, that is not exactly the reason why we buy hardware from the shelf rather than building our own PC platform with ROS. if i need to modify of the shelf products then they are basically not suitable. i am wondering if that is a problem which is unusual. in case it is unusual i would have the RB600 replaced and get another one, if that is a design failure i can't be bothered trying another one.

getting more and more disappointed with MT and RB stuff

PS: in my experience, moving parts and power supply's are the main reasons for outages in the IT world. that is why i (or we in our business) try to do as much as possible without moving parts such as fans and HDD's.

what power supply are you using?
how hot is in the production enviroment?
when it reboots does it say something in the log file, or makes the support output file?
Does the reboot happen on high traffic load or it also happens when there is no load?

i tried the following:

12V 2A
18V 1A
24V 0.8A
and 2 different branded 48V 0.8A and 1A

i also tried the 48V PS via POE on eth1

uldis asked all the questions, but I wanted to comment that RB600 doesn't need a fan, and should work perfectly with all cards inside, even in very hot environments. Maybe there is some other problem

the "other" problem is what gives me a warm feeling . what else can i try to find out if the board is broken ? we had different radios, different locations and different power supply's over time. i had ROS 3.1 to 3.3. nothing left i think if by design the RB600 is tolerant to heat.

i will have to ask our supplier to replace it then.

to answer all your questions uldis.......

the cabinet where the RB600 was located is at 20 - 25 degree Celsius, the other place where it was rebooting was about 10 degree (different mast). the log does not mention the reboot at all. the support file is not created and it happens only if i have traffic. i would not say high volume traffic, only about 15mbit/s total throughput.

PS: i have now a RB333 in place where i had the RB600 yesterday on a 24V 0.8A power supply. works stable now since 6 hours. same config same RF components, just different board.

Seems your board is defect. I've 2 RB600 now running with 4xR52 each. Both work
great. Not a single problem. Before I've sent one back which reboots every few
minutes.

good to know that i am not the only one, thanks for that information !!!!!

hi
we also have rb532 and rb 230 running on ros 3.x that reboot once in a while, they never did with ros2.x !!
sometimes the while is shorter somtimes longer...
but normaly there is no entry in the logs or any supout file....
some other boards run without problmes - so i think that is just a software problem
depnding on configuration and load ..

very strange

try 3.4 and then send the autosupout.rif to support please!

i was just waiting for a request like this

i will try 3.4 and send a support file. but i cant afford to put the RB600 in the same spot again NOW where it had failed before. its first of all up high on a mountain and also i cant cause more outages to help "betatesting" stuff which is sold as a "released product".

i am a bit disappointed.

I didn't mean it like that - the file would help us tell you whether you got a defective unit, or there is another external issue like power, software glitch or so on. Basically you need to RMA it, but I asked for the file because there is a slight possibility that it can be fixed without returning.

ok, i appreciate that you want to help us, thanks for that. i have just send the file to support. i now try ROS 3.4 after i had a test setup which repeatedly rebooted every 2.5 minutes.

thanks
Jan

now.....3.4 is even worse. have just installed and without changing anything i can run a speedtest on the ethernet from windows but i dont even have time to start and login winbox for a 2nd speedtest. it reboots now every 1.5 minutes or less as soon as i put load on it. i just wait for support to come back to me and if that has happen i guess i need to send the RB600 back as it seems to be broke.

let's make one thread out of this issue, it seems you are not the only one:
