2U and 1U Compact Rack-Mount Industrial Computer Chassis
The Nd61220 and Nd61120 industrial computers feature either a
1.2 GHz Pentium III or 2.4 GHz P4 CPU plugged into a 6-slot
backplane with four (4) PCI, one (1) ISA and one (1) PICMG slot (2U
chassis) or a 3-slot backplane with two free slots for PCI expansion
(1U chassis). These industrial PCs are intended for processor-
intensive applications requiring high reliability in an industrial
environment. The Nd61220 is available in compact 2U rack mount
configuration with front-accessible floppy, CD-ROM and removable
hard drive. The Nd61120 is available in compact 1U rack mount
configuration.
These units support up to 512M of SDRAM on the PIII and up to 2G of
SDRAM on the P4 option. System also includes VGA video, 10/
100BaseT Ethernet and the standard suite of PC I/O.
