Due to the weight of Xeon CPU heatsinks they must be secured to protect your motherboard from breakage. The D25 chassis does not have any correspoding mounting holes to support direct chassis attachment of Xeon CPU heatsinks. Use the optional part - EBP-604-2U Xeon CPU mounting plate in order to fasten Xeon socket LGA 604/771 CPU heatsinks with chassis. Detalied info

ATX motherboards have standardized mounting holes to fit different types of chassis. As to CPU heatsink mounting holes - they are not standardized. Determine and spot CPU heatsink mounting holes and then fix the EBP-604-2U plates by selfadhessive tape, glue or by tiny revets. Make shure that standoffs of the plates fit perfectly to the position of CPU heatsink mounting holes at the motherboard, otherwise the CPU heatsink screws would not align to the thread. Since, the plates must be installed prior to installing the motherboard into the D25 chassis, all operations expect pre-scheming and accuracy of the stuff.

The EBP-604-2U plate is supplied as option. It is advisable to order the plate together with chassis.

The Rail Kit to mount chassis to 19" wall mounted cabinet/frame consists of two symmetric Holders - left and right. Each Holder consists of two parts - Holder itself (1) that supports shassis and Bracket (2) that fixes holder in rack and makes holder rigid. Fasten Brackets to Holders with nuts (3) as shown on the picture on the left.

The DR-2U-500 Slide Rail Kit to mount chassis to 19" wall mounted cabinet/frame consists of two symmetric Holders - left and right. Each Holder consists of two parts - Front Bracket (1) and Back Bracket (2). Slide together the front to back sections of the Holders as shown on the picture on the left. Extend the Holders to the length required to fit the rack or cabinet before you install it. The DR-2U-500 Kit supports rack fixing distance on depth L from 400mm to 638mm. Notify, there are two variants to join Back Bracket (A and B). Screw on appropriate nuts (3) (supplied with the Kit) to each bracket, and tighten the front and the back sections.

Install 10 cage nuts in the rack (not supplied with the Kit). Refer to the picture on the left. You should install 5 cage nuts (red marked): 3 - on the front rack (1) and 2 - on the back rack of the frame. Tighten the both Holders with 4 appropriate screws for EACH SIDE of the rack (left and right, front and back). You need to tighten 8 screws total.
Note! Please make sure the salient side of each Holder (left and right) is in the opposite position in the rackmount.
