Enclosure Configuration; Door Locks; Reversing The Doors; Mounting Rails - Tripp Lite SmartRack SR12UB Owner's Manual

5. Enclosure Configuration

5.1 Door Locks

All enclosure doors (including front and back doors, as well as both side panels) have locks that are
accessible by included keys.

5.2 Reversing the Doors

The doors of the enclosure are held in position on the enclosure's frame with two spring-loaded pins. To reverse the door's swing direction, simply release the
pins by pulling them up (lower pin) or down (upper pin) and remove them from the mounting holes on the frame of the enclosure.
Flip the door in the opposite direction and replace the pins in the identical mounting holes on the other side of the enclosure's frame by lining them up with the
mounting holes and engaging them again.

5.3 Mounting Rails

The enclosure comes with mounting rails that have square holes for mounting rack equipment. To install
equipment, use the included cage nuts and other hardware. (See page 7 for installation of cage nuts.)
Warning: Be sure to have the enclosure in its final position on the floor before mounting any
equipment inside. Also be sure to have all the right adjustments on your rails before mounting
equipment. (See below for Adjusting Mounting Rail Depth.)

5.4 Adjusting Mounting Rail Depth

Warning: Do not attempt to adjust rails while equipment is installed in the enclosure. Do not
attempt to use rails without screws installed. (2 per rail.)
The 4 mounting rails are pre-installed to accommodate equipment with a mounting depth of 20.5 inches
(521 mm). Do not adjust the mounting rails unless your equipment requires a different mounting depth.
The front and rear sets of rails can be adjusted independently for mounting of equipment with depths
between 3 inches (76 mm) and 32.5 inches (826 mm).

Each rail is connected to the enclosure with 2 screws: 1 in the upper corner and another in the lower
corner. Using a Phillips-head screwdriver, remove the screws that fasten the rails to the enclosure.
2 Slide the mounting rails to the desired depth and reattach them using the screws you removed in
Step 1.
