Hardware Installation
Installation Requirements and Options
This product must be mounted to an earth grounded rack or chassis.
In general, the switches can be mounted either above a deck or chassis, or behind a
bulkhead or panel in a chassis. Devices should not be mounted closer than 1.2” center to
center. There are threaded inserts for #6 Machine Screws on two different sides. The
screws may protrude a maximum 0.25” inside of the product.
The bottom surface provides two mounting holes 1.75” (or one “Rack Unit”) apart, for
mounting to the side rack rails of a 19” rack. These can also be used to mount on a deck
inside of a chassis.
The front surface provides two mounting holes, which can be used to mount the product
behind a panel or bulkhead in your chassis or fixture box. The file dimension.pdf
contains a drawing showing basic dimensions for panel mounting. See
Help/Documentation/dimension.pdf.
Depending upon the switch configuration, each switch device will draw a minimum of
approximately 30mA and a maximum of approximately 450mA, so you may have to use
powered USB hubs to supply this level of current.
The switch devices operate with USB 1.1 or USB 2.0 full speed.
