Emissions Regulations
Federal Communications Commission (FCC)
T#oFederal Communications Commissionof the U.S. government regulates the
9uencyenergy emanated bcomputing devicesthrough published regu-
{
lations. hese regulations specifytelimitsof radio frequencyemission to pro-
tect radio and televisionreception. All HP Apollo nodes and peripherals have
been tested and complywith these limits. The FCC regulations also ruire that
7
com uting devicesused in the U.S. displaythe agency’slabel and that tere-
e(!
Iat documentation include the followingstatement.
WARNING: This equipment generates, uses,and mayemit radio fre-
quency energy and, if not installed and used in accordance
with these instructions, maycause interference to radio com-
munications. It has been tested and found to complywith the
limits for aClassAcomputing devi~ pursuant to Subpart Jof
Part 15of FCC Rules, which are designedto provide reason-
able protection against such interference when operated in a
commercialenvironment. Operation of this equipment in a
residential area is likelyto cause interference, in whichcase
the user at his own expensewillbe required to take whatever
measures may be required to correct the interference.
Complianceto these regulations requires the usc of shielded cables.
Canadian Department of Communications (DOC)
This digital apparatus does not exceedthe ClassAlimits for radio noise emis-
sionsfrom di~tal apparatus asset out in the Radio Interference Requirements
of the Canad]an Department of Communications.

Electrostatic Discharge (ESD) Precautions
Electrostatic charges can damage the integrated circuitson printed circuit
boards.To prevent such damage from owtn-ring,observe the followingpreca-
utionswhen unpacking and installingthe board.
●

●
●
●
vi
Stand on astatic-free mat.
Wear astatic strap to ensure that any accumulatedelectrostatic charge will
&discharged from your body to ground.
Connect all equipment.together, includingthe static-free mat, static straps,
routing nodes, and peripheral units,
Keep uninstalled printed circuit boards in their protective antistatic bags.
Handle printed circuit boards by their edges,once you have removed them
from their protective antistatic bags.

Product Information 1
Part 1Model 400t, 425t, and 400dl
The followingsectionsdescribe the Model 4(Mlt,42.5t,and 4tMdlsystems.
Model 400t and 425t Overview
The Model 400tand 42Stsystemsare identical exceptfor their @re rocessm
t
and their memo confi rations. The Model 400tuses the MC6803 micropro-
Jrb
cessor and the C6888 floatin -point coprocessoron an emulator board at-
tached to the CPU board. The odel 42Stuses the MC68040microprocessor.
Model 4(K)tsystemsuse a2- or 4-MB memory board in sets of two,whichallows
for systemccmfi rations of 8MB to 32 MBof main memory, in 4- or 8-MB
0!!’
increments. Mel 42Stsystemsuse a2T,4-, or 8-MB memory board in sets of
two,whichallowsfor systemconfigurationsof 8MB to 64 MBof main memory,
in 4-, 8-, or 16-MBincrements.
These systemsinclude the following
.One interface slot for DIO 11or SGC graphics interface boards
.One interface slot for anetwork controller board (either an 8025 or an
Apollo Token Ring network txmtroller)or an HP-IB interfam board
Systemsthat run Domain/OS use the network controllers and the Domain low-
:h~tiipke board. Systemsthat run HP/UX use the HP-IB interface board with
4(%
21Akeyboard and other HP-HIL uman Interface Loop) devices.
P
The systemcan atso include one or tw 200- BWinchesterdiskdrives.The
displayoptions are the following
●Monochrome 19-inch, 1280x 1024,bit-mapped monitor and graphics
controller
.Color I&inch, Iw x1024, Wit-mappedmonitor and graphicswntroller
.Color 19-inch, 1280x 1024,bit-mapped monitor and graphicacontroller

Model 400dl Overview
The Model 400d1isidentical to the Model 400twith the exceptionof the CPU
board. The Model 400dlCPU board doesn’t have the connectors necessaryfor
internal or external disk drives and some I/O interfaces and memory.As aresult,
the Model 400dlconsistsof the followingconfiguration:
Amonochrome 19-inch, 1280x 1024, bit-mapped monitor and graphics
controller
Eight- or 16-MBof memory, by using two or four 4-MB memoryboards
802.3network (AUI or ThinLAN, jumper selectableon the CPU board)
RS232(expandablewith the optional 3-port adapter for Domain/OS sys-
tems)
Domain keyboard
