Rackmounting a DS20E

Rackmounting a DS20E

Hello,
I have a pedestal DS20E that I want to rackmount. I was under the impression that you just had to remove the panels, turn it on its side and attach the rails. However when I
removed the panels, there didnt appear to be any mounting holes for the rails.

Is the pedestal DS20E rack mountable?

Thanks

Gerry,

Yes, the DS20E is rack mountable. DS20Es sold as a chassis with one of the following mandatory mounting kits:

Pedestal/Tower bezel kit 3X-BA56P-PB

Rackmount bezel kit (M-Series Cabinets) 3X-BA56R-RC

Rackmount bezel kit for 9000 Series Cabinets
3X-BA56R-RE

Re: Rackmounting a DS20E

Hello Bill,
Thanks for the prompt reply. We purchased the 3X-BA56R-RE and thats what I'm having the problem with. This does not seem to fit the pedestal/tower bezel kit that we have here.

So maybe this rackmount kit is only suitable for the 3X-BA56R-RC rackmount bezel kit?

You need a rackmount bezel kit too.

Oops nevermind.. I see you did buy the bezel kit. Did you buy the right one for the rack that you have?

Re: Rackmounting a DS20E

The DS20E I have is a 3X-BA56P-PB which is a DS20E in tower format. What I purchased is a 3X-BA56R-RE which is just the rails. Is there something else I need to purchase to convert the DS20E chassis so that I can attach the rails?

Re: Rackmounting a DS20E

Gerry,

You should have everything you need to mount the DS20E in a Compaq/HP 9000 or 10000 rack if you did purchase a complete 3X-BA56R-RE kit. I would have expected installation instructions and diagrams to be included with the kit. It should work as well in a rack cabinet made by Rittal and maybe in a generic 19inch rack. Generic 19inch racks can require additional engineering to get the rails to mount adequately.

Your DS20E Reference Manual has a section and diagrams for rack mounting the chassis in an M-series cabinet. Not the same as the 9000/10000 19inch rack, but it should give you the general idea of where the rails attach to the chassis. You can find a copy at the following url if you don't have a copy:

Re: Rackmounting a DS20E

Bill,
The problem isnt with attaching the rails to the cabinet, its with attaching the runners to the side of the DS20E.

The document you attached shows how to rackmount the rackmountable chassis, but not how to rackmount the tower chassis.

I have taken all the panels off the DS20E and there are no screw holes where the rails should go.

Re: Rackmounting a DS20E

Gerry,

The QuickSpecs for the DS20E shows only one chassis and three different kits for mounting, tower/pedestal, M-series cabinet and the Compaq/HP 9000 cabinet.

Are you sure you have a DS20E and not a DS20? IIRC, the DS20 used a common chassis with the AlphaServer 1200 and a Digital Prioris Wintel server and is a larger chassis than the DS20E. Dimensions of the DS20 are 18.1 x 14.1 x 23.1 in/46 x 35.8 x 58.6 cm and the DS20's rack mount kit consisted of a shelf and a dress bezel (kit 2T-R1200-AB for M-series cabinets). IIRC, the pedestal wheels were removed from the DS20 and the chassis was set on the shelf and then bolted to the shelf. I mounted 16 of those in 8 M-series cabinets back in 1999. We had to deploy them a matter of months before the DS20E started shipping (the DS20E chassis was actually much easier to rack mount and the cpus were upgradeable).

Gerry,

from your Forum Profile:


I have assigned points to 47 of 80 responses to my questions.

Maybe you can find some time to do some assigning?

http://forums1.itrc.hp.com/service/forums/helptips.do?#33

Mind, I do NOT say you necessarily need to give lots of points. It is fully up to _YOU_ to decide how many. If you consider an answer is not deserving any points, you can also assign 0 ( = zero ) points, and then that answer will no longer be counted as unassigned.
Consider, that every poster took at least the trouble of posting for you!

To easily find your streams with unassigned points, click your own name somewhere.
This will bring up your profile.
Near the bottom of that page, under the caption "My Question(s)" you will find "questions or topics with unassigned points " Clicking that will give all, and only, your questions that still have unassigned postings.
If you have closed some of those streams, you must "Reopen" them to "Submit points". (After which you can "Close" again)

Do not forget to explicitly activate "Submit points", or your effort gets lost again!!

Thanks on behalf of your Forum colleagues.

PS. - nothing personal in this. I try to post it to everyone with this kind of assignment ratio in this forum. If you have received a posting like this before - please do not take offence - none is intended!

PPS. - Zero points for this.

Proost.

Have one on me.

Re: Rackmounting a DS20E

It's definately a DS20E. I'll have to have another good look at it, unfortunately it's a long distance away so wont be there for a while, but I'm sure I'll just find the same thing, that there's no fixing holes on the chassis.

Thanks for your help, and I will assign points.

Re: Rackmounting a DS20E

Yep. I've stared at the same box, trying to figure out how to do the same thing.

HP gear is in the middle of the pack when it comes to its rack-mount gear, and the gear is definitely improving. Compared with some of the other gear I've worked with, AlphaServer boxes and rail kits aren't nearly as flexible and often aren't particularly "fun" to retrofit rack-mount -- unless you have the specific rails and the right rack; all the right pieces for the box. Though to HP's credit, there are vendors out there with rack-mount gear and cabinetry that are far more difficult to deal with.

Due to differences in the customer's rack, I ended up using a rack shelf for the last AlphaServer DS20E most recently rack-mounted. The rail kit and the customization would have cost more than the server itself had cost.

If you are going to be working with the HP rack gear, the second-generation 10000 racks are far and away the best of the bunch. Some of the other racks and rack-mounts from most any hardware vendor can sometimes be quite frustratingly unique; mix-and-match mounting is never fun.

Here are some links that can get you into the HP products in this area:
