A Model 20 Brick® measures approximately 6.25" x 8.75" x 1.25" and can be
positioned on a desktop or other flat surface. The vents in the Model 20 housing must
be clear of all obstructions by a minimum distance of one inch (2.54cm).
The front contains activity lights. The back has three 10/100 Base-TX Ethernet
interfaces (ether0 - ether2). It also has a 5VDC connector for the power module and a
connector for an external floppy disk drive, as well as monitor and keyboard ports.
For installation into networks that are subject to surges, a shielded ethernet
cable and / or serial port cable may be needed for regulatory compliance.
The Model 20 comes with an external power module and an optional external 3.5"
floppy disk drive.
For proper cooling and operation, do not stack multiple units on top of each
other.
