Installation Options – The DSLAM may be:

—Mounted with the included mounting brackets in a standard 19-inch (483 mm) or 23-inch (584 mm) rack (including both Bay Networks and Nortel 23-inch racks), or, with separately purchased mounting brackets, in a 21-inch (535 mm) ETSI rack. ETSI brackets are available. See Appendix B, Equipment List.

Up to eight 4900 Series DSLAMs may be stacked on a shelf or desktop. Different models can be mixed in a stack.

Power – The DSLAM operates from a –48 VDC power supply to allow for standard power connections available in a CO. For AC voltage environments, an external AC-to-DC power converter is required.
