Author Topic: Dolby's New Server..DSS200, supersized racks required!! Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 07-13-2009 01:50 PM                     The Error count is definitely something I'll be checking on existing installations. I guess more cable for me to sell...we stock the stuff on 1000' rolls so there is no big deal there (in red and green). Mark, whereas we make all of the cables in the Cat 899 kits, and can control the quality on them, we custom make them on-site (or in the shop to the system) to the lengths needed...so far, zero failures. There is nothing really being pushed by the DCinema version of HDSDI...in fact it is still 1.5G stuff. Nothing too fancy there. It sounds mostly like sloppy compliance with SMPTE 292 on either projector or servers. Scott...I can assure you, in the broadcast grade video world...there is no 50-foot minimums...I've worked with 18" up to 100s of feet and even done repeaters to go beyond 300-feet. Mark...we do use removable side-panel racks when we go to gangables but I don't like wire things from the side. We always rear support extra deep or heavy items too (like MXa amps from QSC). Nothing new there either. Somewhere on this site are photos of some of the racks we have done...there is always a healthy amount of room in the rear to create cable chases, power strips, sufficient bend radius...I just don't go overboard on the depth...heck we were using 25" deep racks when others were still on the 20" deep varieties. I do, however, dislike working on 36" racks unless the bulk of the equipment is indeed over 20" deep.

I have been doing exactly the same since installation #2. We used CAT 899s on the first two just to gauge what was needed ina typical install. I'd reccomend all newbies do the same the first time round. As for QC'ing cables there's nothing difficult that you really need to quality control there... especially when one has put on over 10K BNCs. The mian thing is the cables should be exactly the same length. I like Sam prefer the Mogami Coax probably a thousand fold over Belden. quote: Steve Guttag Mark...we do use removable side-panel racks when we go to gangables but I don't like wire things from the side. Wiring from the side is far better then standing inside anbd you can share the cheese with others working in the shop! Servers generally go in on rack slides with a cable management arm in the rear of the unit. All the cabling gets secured to the management arm so when you slide the server out all the cabling comes out with the unit being slid out. Works really well. The first place I used rack slides was back in broadcast where much of the master control equipment went in on slides... alot of it required frequent servicing or was super difficult to remove fomr the rack by yourself.

I, like my platter-loving friend Steve, greatly prefer for the rack to be easily accessible from the rear without having to "climb into" it. That being said we did front and rear mount equipment and it was so close there is barely enough room to put your hand in between the backs of the equipment (and just barely enough room for the cabling to curve as needed). We even had to mount various converter boxes and such to the sides of the rack to get it all in there, but unless you pull the side panels off...you will never see all of that. Moral of the story...never again!  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

However, for HDSDI...Belden 1694A is very much the standard by which others are judged. I tend to go to Mogomi for uber-flexible cables...their mic cable and snakes are tough to beat...in fact...they are generally all very good. We haven't used Canare much other than their star-quad cables...however we tend to use Belden now.

I also have their crimp tool. Brad, What did you mount in there that was so deep? The Doremis are not all that deep... or why not just use two shallower racks? Was it a cost factor?

It sticks out the front of the rack by a foot. I am waiting for my "boss" to return the mounting rail slides that he had modified to better fit the rack. (His idea, not mine. I thought the full-length rails would fit just right....) It isn't quite the horror show I thought it would be, but I still don't like it. Once it's fully mounted I'll see about taking some pics.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 07-20-2009 02:03 PM                        Sounds like the box channels we made to install dts into Smart racks. Darn things stuck out almost 5 inches!
