Noise:
The PSU is a bit high pitched noise from and no fan controll to adjust it.
The CPU fan is at level 4 in the bios at default (from 1 to 9, where 9 is full speed).
This makes it not audible against the PSU fan, and keeps the CPU temp at 33 when idle.
The 4 chassis fans makes "wosh" sounds if that makes any sense?
Default there's no fan control for these either, but, the socket on the fan printboard they're attached to is a 3 pin fan connector.
I guess I can buy a cable to connect them to the motherboard to spin them down a bit.
Anyway, I put the lid on and put it away in my "server room" in the open rack.
It's 1 meter from the door.
With me sitting another 5 meters away, and not able to hear it at all. (And my hearing is very good).
If I stand next to the door, and listen for it, I can hear it, but it will never bother me.
I would have no trouble sleeping in the room next to the one I keep the server in.
It's a normal door, no soundproofing.
That said, this would be a no go if I had to work with it in the same room, so there IS enough noise from it to be bothered if you use it that way.
There's no room for 120mm fans in the chassis. And I've not looked for replacement of the four chassis fans either, but looks like it's posible.
If there were any component that I would have done something to, it would be the fan in the PSU.
Moving on to the racking questions.
I'm going to move it to another level, and then I'll be able to take some usable pictures.
But I can give you some numbers.
The front opening of the rack is 45cm (17.7inches).
To be able to slide in the 2212 I had to mount the rails precisely or else it wouldn't slide in.
I mounted the side arms to the rack so that my usable depth is 80.8cm (31.8 inches).
The RL-26 I got had no problem with that, and would also be ok if I extended the sidearms all the way to get the racks max depth. (a couple more inches at most)
How "small" I can make the RL-26 I will have to meassure when I move it in a day or two.
If I have to guess based on how precise I'm able to measure it as it stands, I'll say that the RL-26 at the shortest would be 65cm (25.5inches)
Please, don't trust that number until I can verify it for you!
Thanks for the verification when you have time.
I guess that Norco is right, but the RL-20 is not supposed to keep a 4U in place?
Supposedly, per Norco.
I ordered from Norco in The Netherlands (ri-vier.nl)
Got very good service from Richard there.
The rails is supposed to be from Norco, not ball-bearing but with grease and in four parts.
One part to mount on the chassis, two parts that slides into eachother with the part on the chassis.
And the last part is the back bracket which is loos so the rails would fit the prefered mounting depth of the rack.
I can take pictures and precise measures of the rails once I move it in a day or two.
Thanks.
I'm not sure if third party rails would fit (mounting holes would fit I guess, but the width of the chassis and so on... I'm not sure).
Would love to be able to use tool-less rails, maybe the supermicro ones will fit?
I haven't looked at these. I'll have to do a search.
I have a pair of HP tool less rails here, will try to see if they will fit.
I'm not able to extend the chassis all the way out without removing it from the rails completely.
So for service inside the chassis you'll have to pull it out of the rack.
It's not screwed to the rails so you'll be able to slide it as far out as you please, but it will not support it all the way out so that you can open the chassis.
That is a bummer. To me - this is the main purpose of the rails. From what I've read, the ball bearing rails allow you to pull the chassis out all the way. However, the ball bearing rails may or may not fit.
A picture is worth a tousand words, so I'll come back with pictures for you regarding the rail mountings.
Thanks.
But to give you a clue, look at this picture of the right part of the rack.
http://h30094.www3.hp.com/buynowall_assets/large_images/3397050-3.jpg
The rails are mounted flat to the backside of the holes in the background in the picture.
On this side of the same holes I put the square hole bracked that was with the rails, and two screws to hold it in place.
The chassis is then screwed with 1 screw in the middle hole at the frontmost holes in the picture.
The rails have 3 holes, so if your rack only has one set of mounting holes you can use the middle hole in the rails to fasten the chassis.
Sorry for not having the photos ready yet, I'll see what I can do tomorrow.
But I have to move it (bad planning from my side) so pictures are coming, and better measures of everything.
Sorry for any bad english in the middle of the night here.
No problem. Appreciate the help.
