Adding the new 25-drive DAE Take the following actions to install the new 25-drive DAE into the system. Removing a filler panel In most cases, the front space into which you will install the enclosure is covered by a filler panel, which is attached to latch brackets. If one or more filler panels cover the space where you want to install the enclosure, remove each panel using the procedure that follows. Procedure 1. Remove the filler panel. 2. Use a flatblade screwdriver or similar tool to pry off the latch brackets ( Figure 1 on page 10). Figure 1 Prying off a latch bracket CL4064 Installing the rails in the cabinet Note The snap-in rails are dedicated left and right, and cannot be interchanged. Procedure 1. Orient the rails. Face the front of the cabinet when orienting the left and right rail placement. The front edge of each rail is stamped L or R. 2. From the rear of the cabinet, insert the adapters into the holes on the rear rack channel with the rail extended as shown in Figure 2 on page 11. 3. Push the rail into the rear mounting holes until the spring clips snap into place on the outside of the rear channel.

CAUTION Ensure the holes on the rail line up with the holes on the cabinet. This will ensure proper alignment of the rails. Also, check that the rails are level and using the same cabinet Unit markers from front to rear. Ensure you are using the same unit markers from the front of the cabinet to the rear of the cabinet. Figure 2 Push rail into rear channel mounting holes 4. From the rear of the cabinet, secure the rails in place using one M5 screw on each rail. Figure 3 Installing the M5 Screw 5. Working from the front of the cabinet, align the adaptor with the mounting hole on the front of the rack as shown in Figure 4 on page 12. CAUTION Ensure the holes on the rail line up with the holes on the cabinet. This will ensure proper alignment of the rails. Also, check that the rails are level from front-to-back and left-to-right. Ensure you are using the same unit markers from the front of the cabinet to the rear of the cabinet. 6. Push in on the spring clip while pulling the rail forward. When the spring clip is forward of the front rack channel, and the adaptor is in the mounting holes, release the spring clip so it holds the rail in place.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
