CHAPTER 1
GENERAL INFORMATION
The iSBC 655 Syste Chassis (figure 1-1) is packaged
as a completelyasse bled microcomputer chassis.It
consists of a po er supply, a four slot card-
cage/backplane, du I fans, anda frontpanel.This
chapter providesaleneral descriptionof the chassis
in addition to a spec fications table.
1-2. CHASSIS DESCRIPTION
The iSBC 655 System Chassisis designedto be rack
mounted, using RItTMA compatible components.
The 19 inch front J1lanelhas the following switches
and indicators:aporer ON/OFF indicator switch; a
RESET switch; an NTERRUPT switch;a RUN in-
dicator; and a HA T indicator. The rear panel is
easily removed for q ick access to the cardcage.
The two cooling fans are located on the left side of
the chassis, one directed toward thepowersupply
and the other directed toward the cardcage. These
fans supply adequate ventilation to keep the fully
loaded chassiswithin temperaturetolerance «55°C).
The chassisutilizesthe iSBC604 Cardcage-
Backplane for housing a maximum of four Intel
iSBC compatible boards. The backplanemay be ex-
tended to additional external cardcages or monitored
through a Multibus plug located on thebackplane.
Output power isfurnished bythemodular iSBC 635
Power Supply. The supplyismounted directly
behind the front panel and iseasily removed or
calibrated.Accepting either 100,115, 215, or 230
Vac, the supply provides fully regulatedand pro-
tected +12,+5,-12 and -5 volt outputs.A power
line monitor signal is also provided for use with
power-down subroutines.

plied ~ith the iSBC 655 System Chassis:

A ChafiS wiring diagram, front panel logicdiagram,
and re lacement parts listing are located inChapter 4
of this manual.Similar diagrams and parts listings
pertaiing to the power supply and cardcage are_
locatein the Service Informationchapters of the
other anuals.
Thef lowing equipment is suppliedwith the iSBC
655 Sytern Chassis: front panelwith switches and in-
dicators, two fans, power supply, cardcage-
backplane, fuse, line filter,115 Vacpower cord, and
one 25 inch RS232 I/O cable.
All rack mounting hardware isuser supplied.
Chapter 2describes proceduresfor mountingand
lists recommended parts.If the chassisisoptioned
for 230volt operation,thepower cordis not sup-
plied. Any I/Ocables, with the exception of the
RS232 cable described in section 1-4, arealso user
furnished. The hardware referencemanual for each
iSBCboard will provide a table of compatible I/O
connectors recommended byIntel (not all boardsre-
quire I/Ocables, however).
Specifications of the iSBC655 SystemChassis are
listed in table 1-1.
