Slide the chassis down so that the mounting screw heads are in the narrow portion of the keyhole slots.5. Tighten the screws to secure the chassis in place. For extra support, use additional screws.NOTEFor better grounding of the chassis to the rack, attach the chassis using star washers. You should also use starwashers with any single-hole grounding lugs to keep the lugs from rotating.6. Repeat step 2 through step 5 to mount each chassis in the rack.Installing modulesUse these procedures to install modules into empty slots. The same procedure applies to all modules.The following sequence for installing multiple modules is important to ensure proper fit:• For the 4-slot and 8-slot chassis, install modules right-to-left, beginning with the lowest row and moving up.• For the 16-slot chassis, begin by filling the slots from the left side of the router, and work towards the right side.DANGERThe intra-building ports of the equipment or subassembly is suitable for connection to intra-building orunexposed wiring or cabling only. The intra-building ports of the equipment or subassembly MUST NOTbe metallically connected to interfaces that connect to the outside plant (OSP) or its wiring. Theseinterfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described inGR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of PrimaryProtectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.1 Equipment rack 2 Mounting holes12
