Preparing Yo ur VXI System for Use
The HP E840xA mainframes are sh ipped from the factor y ready to use. This
section describes important mainframe installation procedures.
AC Power
Requirements
The HP E840xA mainframes can be operated at line voltages of
90 VAC to 264 VAC, and line frequencies of 47 Hz to 66 Hz. The
mainframe can also operate at 360 Hz to 440 Hz with line voltages of
90 VAC to 132 VAC.
The mainframes ship wi th a power cord and wit h a fast blow fuse in sta ll ed.
The fuse is suitable for all line voltages. The fuse is not user replaceable.
Refer to “Replacement Power Cords” on page 215 for additional
information on E840xA p ower cor ds and o n fuse r eplac ement. Appendi x A
contains complete input power specifications.
WARNING The power cord is the only way to disconnect the mainframe
from AC power and, therefore, it must be accessible to the
operator at all times. When the HP E840xA mainframes are
mounted in a system cabinet, the power cord need not be
accessible since the cabinet must have its own disconnect
device.
Positioning th e
Mainframe for
Adequate Cooling
VXI instruments are c ooled by air drawn through the back of the mainfra me
and exhausted out the sides . The po wer supply is cooled by air drawn fro m
the right side (facing t he mainframe) and exhausted out the lef t si de. When
placing the mainframe on a work bench or if the mainframe is rack mounted,
provide at least a one inch clear ance at the back a nd sides to all ow for proper
air flow.
Air filters are not necessary on these mainf ra mes. However, an optional ai r
filter kit (mainfr ame opti on 938 or HP E8401-80 938) is avail able f or use i n
harsh environments. The airflow is restricted less than 10% with the air filter
installed. Refer to “HP E840xA Air Filter Kit” on page 248 for installation
information.

Connecting the
Mainframe to a
Permanent Earth
Ground
The mainframe must be connected to a permanent earth ground for line
frequencies greater than 66 Hz. This connection is made on the back of the
mainframe:
1. Connect a 16 AWG (1.3 mm or larger) wire to the PEM nut sho wn in
Figure 1-1. The wire must be green with a yellow stripe, or bare (no
insulation). Use a m4 x 10 s crew, grounding lug, and toothed wash ers
(or toothed lug) as shown in the Figure.
2. Attach the other end of the wire to a permanent earth ground using
toothed washers or a toothed lug.
WARNING For protection from electrical shock when operating at
frequencies greater than 66 Hz, connect the chassis ground
terminal to permanent earth ground.
AVERTISSEMENT Risque de Choch èlectrique. Si la frèquence du secteur est
supèrieure à 66 Hz, relier la borne de masse du chassis à une
prise de terre fixe.

Installing VXI Instru ments
The HP E840xA mainframes have 13 slots labeled 0 through 12. Any VXI
instrument can be installed in any slot; however, slot 0 is reserved for
devices capable of providing the system’s slot 0 functionality. This
functionali ty includes:
•locating instruments installed in the mainframe
•managing (arbitrating) data flow across the backplane
•providing the system clock (SYSCLK - 16 MHz)
Examples of these devices are the HP E1406 Command Module and
embedded controllers such as the HP E623x series VXI Pentium PCs, the
HP RADEPC7B PC, and the HP E1497/E1498 V743 controllers.
Multiple instruments which combine to create a virtual instrument (e.g. a
scanning multimeter), and i nstruments which access th e backplane local bus
should be installed in adjacent slots.
1. To prevent damage to the VXI instruments, turn o ff the mainframe
prior to installing the instruments.
2. Insert the instrument in to the mainframe by aligning the instrument
with the card guides inside the mainframe. Slowly push the
instrument in to th e slot until it sea ts in the backplane connectors. The
front panel of the instrument should be even with the front edges of
the mainfram e.
3. Tighten the retaining screws on the top and bottom of the module.
WARNING All instruments withi n the VXI mainf rame are grounded through
the mainframe chassis. During insta llation, tighten the
instrument’ s retaining screws to secure the instrument to the
mainframe and to make the ground connection.

VXI Logical
Address
The Enhanced Monitor of the HP E8402 and E8404 mainframe s plu gs in to
the VXI backplane f rom the rear of the mainframe. It does n ot occupy a slot
in the mainframe or tie-up th e MODID line. The enhanced monitor is a
message-based device, allowing easy communication over the VXI bus (f or
example, through a command module or embedded controller) or a standard
RS-232 interface. The enhanced monitor does require a VXIbus address;
224 is the factory default. Figure 1-4 shows the rear panel of the HP
E8402/E8404 VXI mainframe with the Enhanced Monitor logical address
switches and RS-232 interface.

RS-232 Interface The RS-232 interface on the r ear panel of the Enhanced Moni tor mainframes
(HP E8402 and E8404) can be used to control the E nhanced Monitor f rom a
computer or a terminal.
Refer to Chapter 3 for RS-232 programming information. The
SYSTem:COMMunicate:SERial ... commands set and/or modify the
configuration of the Enhanced Monitor’s serial interface. Serial
communication commands take effect after the end of the program messa ge
containing the command(s).
Default RS-232 parameters are:
•Baud: 9600
•Bits: 8
•Parity: None
•Stop bits: 1
•DTR/RTS: On
•Pace: XON
•Echo: On
•ERES: On
•Line buffer: On
Note If you use the Enhanced Monitor RS-232 interface (located on the
back of the mainframe) while the mainframe is in the standby mode,
you must supply an external +5Vdc to the +5VEXT connector
(located near the RS-232 interface). If you use the RS-232 interface
while the mainframe is powered on, you do not need to provide the
external +5Vdc.
External +5V Supply The External +5V supply is for powe ring the Enhanced Mon itor (includ ing
the RS-232 in terface) while the mainframe is powered down (standby
mode). This requires a stable 5 vol t supply c apable of 1.5A a mps maximum
(500mA typical, refer to speci ficati ons in Appendix A). Refer to Figure 1-4.
Getting Started 25Chapter 1
Using the Remote
Power-On Pins
The remote power-on pins ( pins 5 and 18) of the Diagn ostic Connector allow
you to turn the mainf rame on and off without using t he front panel On/Stdby
switch. With the On/ Stdby switch in the Stdby (off ) position, co nnecting pin
5 to pin 18 on the diagnostic connector turns the mainframe on.
Disconnecting pin 5 from pin 18 turns the mainframe off.
Note Pin 18 is ground in the HP E8402 and E8404 mainframes. Therefore,
you only need to ground pin 5 to turn the mainframe on.

resistor, heat damage may prevent the
resistor from being re-inst alled to re-enable the On/Stdby
switch.
To access the Monitor Display Board and resistor:
1. Turn off the mainframe and remove the power cord.
2. Remove the mainframe cove r by r emoving the 10 m3x6 fl at head t orx
screws.
3. Remove the 0Ω resistor by heating both sides simultaneously with
soldering irons. Separate the resistor from the board by gently
pressing the tips of the soldering irons together.
4. Save the resistor in order to re-enable the On/Stdby switch. Again,
heat damage may prevent the resistor from being re-installed.

Using the Enhanced Monitor
The Enhanced Monitor on the front panels of the HP 840xA mainframes
allow you to monitor power supply voltages, mainframe temperatures, fan
operation, and backplane activity. Figure 2-1 shows the mainframe front
panel.
The enhanced monitor provides features such as:
• Monitoring the mainframe operating status including: blower status,
slot temperatures, an d power supply voltage s, cur re nt, and power. The
Enhanced Monitor generates a warning if any of these parameters
exceed limits. Refer to Chapter 3 for programming details.
• User-definable temperature limits for indi vidual slots; if the limit is
exceeded, a beeper sounds, LEDs flash, and the display shows the
warning condition.
• Storing a history of power supply voltages, currents, and power; slot
temperatures; fan speeds; events such as mainframe power cycled
on/off, etc.
In addition, you can:
• Perform internal Enhanced Monitor Self Tests. These verify its fans
and its ability to measure the slot temperatures and power supply
voltages and currents, etc.
• Set and query Enhanced Monitor system parameters. The Enhanced
Monitor functions are programmable through either the system
commander (command module or embedded controller) or via an
RS-232 port on the back of the mainframe.
• Write user text messages to the front panel display. This is useful for
communicating with an operator.

Using the Enhanced Monitor 31Chapter 2
Using the Enhanced Monitor
The Enhanced Monitor is a separate PC board that plugs into the VXI
backplane from the rear of the mainframe. In this way it does not occupy a
user slot on the front of the mainframe. The Enhanced Monitor uses a
standard-defined P 1 Connector but a uni quely-defi ned P2 Connector. It is a
message-based, slave-only VXI interface card, complete with its own VXI
logical address. Refer to Chapter 3 of this manual for SCPI programming
information. This se ct ion pro vid es gener al in form ation abou t the Enh anced
Monitor.
•RS-232 Interface supports communication with a terminal or
computer for remote monitor in g pur pose s onl y. Refer to Chapter 3 for
SCPI programming information.
-- All SCPI command are supported by the RS-232 interface.
-- The RS-232 interface is set-up only through SCPI commands.
Settings are stored in non-volatile memory. Factory defaults are:
9600 Baud, 8 bits, No Parity, 1 Stop Bit, DTR/RTS On, XON
Pacing.
•Ambient Tempe ratur e Monitor (±2 °C). The sensor is locat ed in the
intake air stream path just above the mainframe impeller.
-- A user-defined limit can be set, de fault is 55
°C.
-- Limit is restored from non-volatile memory at power-on.
-- When the limit is exceeded, the monitor gen erates a warning on the
display, sets a status bit, the temperature LED flashes, and the
beeper sounds (if enabled).
•Power Supply Temperature Monitor (±2 °C). The sensor is located
under a power supply transformer . Th e re adi ng i s i ndi cat iv e of over al l
power supply loading.
-- If the temperature exceeds an expected level, the monitor generates
a warning on the display, sets a status bit, the power supply LED
flashes, and the beeper sounds (if enabled).
•Module Exhaust (Slot) Temperature Monitor (±2 °C). Three
sensors, front, middle, and rear are located above each slot.
-- Temperatures may be queried in actual
°C or as temperature rise
above ambient (in
°C).
-- User-definable limits can be set for the entire cardcage or on a
slot-by slot basis.
-- Limit may be set in actual temperature (default is +65
°C) and as
temperature rise above ambient (default is +15
°C).
-- Limits are restored from non-volatile RAM at power-on.
-- If a slot temperature exceeds the specified limit, the monitor
generates a warning on t he display, sets a status bit, the temperatur e
LED flashes, and the beeper sounds (if enabled).
32 Using the Enhanced Monitor Chapter 2
•Voltage Monitor measures all seven power supply voltages (+5, ±12,
±24, -5.2V, and -2V).
-- Voltages outside of fixed limits (based on VXI specifications)
causes the mo nitor to generate a warning on the display, set a status
bit, the Power Supply LED flashes, and the beeper sounds (if
enabled).
•Current Monitor measures the current from all seven power supplies
(+5, ±12, ±24, -5.2V, and -2V).
-- Currents exceeding user-specified limits (defaults to mainframe
specifications +10%) cau ses the monito r to generate a warning on
the display, set a status bit, the Power Supply LED flashes, and the
beeper sounds (if enabled).
•Power Monitor calculates the total output power of the power supply
[Σ(V*I)].
-- Total output power exceeding user-specified limits (defaults to
mainframe power supply maximum) c aus es the moni tor t o ge ner at e
a warning on the display, set a status bit, the Power Supply LED
flashes, and the beeper sounds (if enabled).
•Backplane Activity Monitor monitors acti vit y on t he VXI ba ckpl ane.
-- The DS0 and DS1 backplane lines are monitored. Activity is
displayed through the front panel Activity LED. No warning is
associated with this activity.
-- SYSFAIL is also monitored. Assertion of SYSFAIL (by any VXI
module) is shown by the amber SYSFAIL LED on. It will not sound
the beeper or generate a warning on the display.
•Fan Monitor monitors the operation of the fans.
-- Fan speeds outside a fixed range generate a warning on the display,
sets a status bit, the FAN LED flashes, and the beeper sounds (if
enabled).
-- Fan level is returned as a percentage (%) of maximum speed.
•Fan Controller adjusts mainframe fan speed based on the power
supply, ambient, and individual slot temperatures. The fan can be set
to maximum or FULL speed by a front panel switch.
-- In the Variable mode, if the power supply temperature exceeds
an expected level, the fan speed increases to maximum.
-- In the Variable mode, if the ambient temperature exceeds +50
°C,
the fan speed increases to maximum.
-- In the Variable mode, if any VXI module exhaust temperature
approaches a user-defined limit, fan speed increases.
-- Otherwise, fan speeds operate at the lowest possible speed to
maintain user-specified cooling level.
•Time Monitor records:
-- Total hours of operation
-- Time-on since power on, last test, last calibration, last history reset.
-- Time remaini ng until the next maint enance. This time ca n be set and
queried by the user. A warning is generated w hen the timer reaches
0. Note: this is disabled as shipped from HP.
