The UPS comes with standard 46.5-cm (19-inch) rack mount brackets (ears) and cleats installed
and mounting rails for rack mounting included. The rails support the UPS and allow adequate air
flow. There are two steps to install the UPS in a rack. This section describes each in detail.
1. Install the mounting rails in the rack (required for four-post racks only).
2. Load the UPS into the rack.
Check the rack to make sure it will not tip after moving the mounting brackets.
