After being in business for about a year it bacame evident we needed a new rack:
So I embarked on a slightly ambitious plan to build my very own DIY rack. It is a 12U 126 hp. It has 8.5 amps on the +12V and -12V rails, 8 amps on the 5V rail. I used Tiptop rails and hand cut the metal sides. Here is a shot of it during construction:
It looked so big…I thought I would never need another case…but it filled up almost immediately. The last year and a half has been spent taking modules in and out to make room for the stuff I needed at the moment.
So finally 6 months ago I made plans for a second case. After several iterations and ideas I came up with a case that is similar to the old one. The new case is 146hp – 4 3U rows and 3 1U rows interspersed.
I used Vector rails which come in 300HP lengths. The biggest rails I could cut while getting two rails out of the raw stock was about 149hp as the saw blade takes 1/8 inch of material per cut. I settled on 146hp so I could use 30″ pieces of Baltic Birch plywood. I have limited fab capacity at the Abbey and 4′ x 8′ sheets of plywood are not practical.
New Rack Specs:
4 3U rows with a 1U row in between the 3U rows.
+12V: 12.5 Amps
– 12V: 12.5 Amps
+5V: 8 Amps
