Mounting options
You can use choose three different options for
mounting your PDU in an enclosure, depending on
your preferences and the type of enclosure. All
options require that you first attach mounting
brackets to the PDU.
• Vertical mounting
For any standard 19-inch rack, you can
attach the brackets to the enclosure using
the screws provided.
For a NetShelter VX enclosure (AR2100
series), you can mount the brackets to the
enclosure by snapping them into place
(toolless mounting).
• Horizontal mounting: For any NetShelter
enclosure, you can mount the brackets to the
enclosure using the screws provided.
Horizontal mounting uses 1 U-space.

PDU in the enclosure. (See the figures on the
