NETBuilder software runs on a PC flash memory card. If you have the base
chassis and a CEC 20 module, you must install the flash memory drive
according to the NETBuilder II Flash Memory Drive Installation Guide.
The EZBuilt NETBuilder II system with CEC 20 module has the flash memory
drive already installed. The DPE module has integrated flash memory drives.
The DPE or CEC 20 module is the main processor for the NETBuilder II
bridge/router. If you have the base chassis, you must install either module. In
the EZBuilt system, the main processor is already installed. Refer to the
ppropriate main processor module guide for installation instructions.

Mount the chassis on a tabletop or in a 19-inch, 2- or 4-pole rack.
