Installing Your Unit
Place the unit in the desired location. You can mount it in a rack for your
convenience, or place it on a solid, stable surface. If you do not plan to install the
GSS 4490 in an equipment rack, proceed to the

Racks are marked in vertical increments of 1.75 inches (4.44 cm). Each increment
is referred to as a rack unit (RU). A 1-RU device is 1.75 inches (4.44 cm) tall.
