2.Position the SmartStack STS16-20D/STS16-20R, with the exposed mounting brackets, in the rack or cabinet and slide it up or down until the bracket holes line up with the rack holes. Attach the chassis brackets to the rack using the Allen screws you removed in the previous step and the nuts supplied with the switch. Close the cap again to conceal the screws.

➽Note: Only fixed brackets are supplied with these units. If you want to install a sliding pullout mount, you will need to provide the extra mounting hardware.

Table-Mounting

The SmartStack STS16-20D/STS16-20R operates at a low noise level, which makes it suitable for a large enough flat surface such as a table.

Four self-adhesive pads are supplied with the switch. The pads must be mounted in the four recesses on the bottom of the switch. When the pads are mounted, simply place the switch on a clear, level location. Leave enough room around the switch for ventilation and access to the controls and cable connectors.

➽Caution: Due to weight constraints, place no more than three units (or the equivalent weight of other equipment) directly on top of another chassis. More than three units on top of another unit may cause damage to the lower unit.
