Issue:

What are the Minimum and Maximum mounting depths for Smart-UPS rack mount rails?

Product Line:

Smart-UPS

Environment:

All rack mounted models, All Serial Numbers

Cause:

Smart-UPS Rackmount UPS units (typically designated with "RM" in the part number) include a system of rails and brackets to mount the unit in a typical IT rack enclosure. The rails are adjustable to allow for a range of different sized racks. For specifics of how to mount your unit, please refer to the installation documentation included with your UPS.

Resolution:

For all Smart-UPS products 10Kva or less:
The minimum depth for the rails is 21.75" and the maximum depth is 36".
NOTE: If your Smart-UPS is equipped with cleats (metal pieces attached to the sides of the Smart-UPS chassis that slide into the rails) the minimum depth is 29"".

For Smart-UPS products over than 10Kva:
The minimum depth for the rails is 27.5" and the maximum depth is 33".

 

If you are using your APC rail kit to mount non-APC equipment your experience may vary. 
Please note that some networking specific or custom enclosures may need to be adjusted to accommodate the depth of the rails.
