    Rack Requirements for an EX Series Redundant Power System

    You can mount the Redundant Power System (RPS) on either two-post racks or four-post racks.

    Rack requirements consist of:

    • Rack type
    • Mounting bracket hole spacing
    • Rack size and strength
    • Rack connection to the building structure

    Table 1 provides the rack requirements and specifications for the RPS.

    Table 1: Rack Requirements and Specifications for the RPS

    Rack Requirement


    Rack type

    Use either a two-post rack or a four-post rack. You can mount the RPS on any two-post or four-post rack that provides bracket holes or hole patterns spaced at 1 U (1.75 in./4.45 cm) increments and that meets the size and strength requirements to support the weight of the RPS.

    Mounting bracket hole spacing

    The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that you can mount the RPS in any rack that provides holes spaced at that distance.

    Rack size and strength

    Rack connection to building structure

    • Secure the rack to the building structure.
    • Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum stability.

    One pair of mounting brackets for mounting the RPS on two posts of a rack is supplied with each RPS. For mounting the RPS on four posts of a rack or cabinet, order a four-post rack-mount kit separately.
