Ensure that the outlet has a proper safety ground. Do not defeat the safety
ground by using a 2-prong adapter or extension cord. Doing so voids the new
product warranty.

2.4.3 Rack Installation for ZX-250r
You can install the SmartCell ZX-250r switch in a standard 19-inch mounting rack by using the provided side-mount
brackets. Each switch occupies 4.5 inches of rack space or between two and three “rack mounting units.” This
installation results in an air gap of approximately 0.5 inches vertically between switches. There must be an air gap of
at least four (4) inches on either side of the rack for proper air flow to the cooling fans. (ZX-250r chassis are 17.5 inches
wide by 20.5 inches deep.)
