5. Enclosure Configuration (continued) 5.4 Mounting Rails The enclosure comes with mounting rails that have both square and tapped holes for mounting rack equipment. To install equipment, use the included cage nuts and other hardware. (See page 6 for installation of cage nuts.) Warning: Be sure to have the enclosure securely mounted to the wall, or in its final position on the floor before mounting any equipment inside. Also be sure to have all the right adjustments on your rails before mounting equipment. (See below for Adjusting Mounting Rail Depth.) 5.5 Adjusting Mounting Rail Depth Warning: Do not attempt to adjust rails while equipment is installed in the enclosure. Do not attempt to use rails without screws installed. (2 per rail.) The 4 mounting rails are pre-installed to accommodate equipment with a mounting depth of 20.5 inches (521 mm). Do not adjust the mounting rails unless your equipment requires a different mounting depth. The front and rear sets of rails can be adjusted independently in 1/4-inch (6mm) increments for mounting depths between 3 inches (76 mm) and 20.5 inches (521 mm). 2 1 Each rail is connected to the enclosure with 2 screws and 2 cage nuts: 1 set in the upper 1 corner and another in the lower corner. Using a Phillips-head screwdriver, remove the screws that fasten the rails to the enclosure. 2 Move cage nuts to desired depth and reinstall. 3 Slide the mounting rails to the desired depth and reattach them using the screws you removed in Step 1. 3 6. Wall Mounting the Enclosure Warning: Do not attempt to mount the enclosure to the wall with equipment mounted in the enclosure. 6.1 Mounting There are 16 keyhole cutouts on the back door of the enclosure. Each keyhole can accommodate an M10 or 3/8" bolt. The holes are on centers and beginning with the two innermost holes, the centers are 12.625", 14.875", 17.125" and 19.375" apart, respectively moving outward and horizontaly. Holes are then 21.362" apart vertically, as shown in the diagram. Using a level, measure to position your mounting areas precisely. Use appropriate fasteners (not included) to secure the enclosure to the wall. Warning: The area you plan to mount the enclosure to must be able to withstand the weight of the enclosure and all mounted equipment. For the weight of the enclosure and its capacity, see the specifications on page 8. 19.375" 17.125" 14.875" 12.625" 16" 16" 16" 16" 21.362" 5
