Decide at what level you want to install the shelf. The 3580 requires two units (EIAs) of rack space (see 2 in Figure 1).Note: All vertical rack measurements are given in rack units (U). One U is equal to 4.45 cm (1.75 in.). The U levels are marked on labels on one front-mounting railand one rear mounting rail.2. With the sides and back of the shelf facing up, carefully lift the shelf into the rack between the front and back rack rails with the shelf flanges behind the front rackrails.3. Align the holes in the shelf flange exactly with the holes in the front rack rails.4. Holding the shelf 1 level, insert a screw through the top hole 3 in each front flange of the shelf. Loosely thread the screws into the front mounting rails.Figure 1. Front view of shelf attached to rack rails5. Check that the shelf is at the same level on the four mounting rails.6. Insert a screw through the bottom hole 4 in each front flange of the shelf. Loosely thread the screws into the front mounting rails.7. Tighten all mounting screws with a 7 mm nut driver or a 7 mm socket wrench.8. Route cables down one of the rear rack rails by threading each tie wrap (see 5 in Figure 2) through a hole in the rail and around the cables. One tie wrap must belocated near the rear of the 3580; the other must be located farther down the rack rail. Tighten cable ties securely around the cables so the cables cannot be pulledout. Cut off tie wrap excess.Figure 2. Rear view of shelf with cables attached to rack rails with tie wrapsThe shelf installation is complete.
