Front Panel Features
The HP E8400A front panel allows you to monitor power supply voltages,
mainframe temperatures, fan operation, and communication across the
backplane. Table 1-1 describes these features.
Table 1-1. HP E8400A Mainframe Front Panel Indicators and Switches.

12 Using the HP E8400A Mainframe Chapter 1
Using the Remote
Power-On Pins
The remote power-on pins (pins 5 and 18) allow you to turn the mainframe
on and off without using the front panel On/Stdby switch. With the
On/Stdby switch in the Stdby (off) position, connecting pin 5 to pin 18 on
the diagnostic connector turns the mainframe on. Disconnecting pin 5 from
pin 18 turns the mainframe off.
Disabling the On/Stdby
Switch
The front panel On/Stdby switch is disabled by removing surface mount
resistor R108 located on the basic monitor board (Figure 1-2).

Using the HP E8400A Mainframe 13Chapter 1
Caution After removing R108, heat damage may prevent the resistor
from being re-installed to re-enable the On/Stdby s witch.
To access the basic monitor board and resistor:
1. Turn off the mainframe and remove the power cord.
2. Remove the mainframe cover by removing the 10 m3x6 flat head torx
screws.
3. Remove the 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.
Preparing Your VXI System for Use
The HP E8400A is shipped from the factory ready to use. However, before
installing VXI instruments and turning on the mainframe, refer to the
following:
•AC Power Requirements
•Airflow Requirements
•Installing VXI Instruments
AC Power
Requirements
The HP E8400A mainframe 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 mainframe ships with a power cord and with a 250V, 15A fast blow fuse
installed. The fuse is suitable for all line voltages. Refer to Chapter 3 for
additional information on E8400A power cords and on fuse replacment.
Appendix A contains complete input power specifications.
WARNING The p o wer 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 E8400A is mounted in a
system cabinet, the power cord need not be accessible since
the cabinet must have its own disconnect device.
14 Using the HP E8400A Mainframe Chapter 1
Connecting the
HP E8400A 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 shown in
Figure 1-3. The wire mu st be green with a yellow stripe, or bare (no
insulation). Use a m4 x 10 screw , gr ounding lug, and toothed wa shers
(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 prote ction from electrical shock when operating at
frequencies greater than 66 Hz, connect the chassis ground
terminal to permanent earth ground.
Figure 1-3. Connecting the HP E8400A to a Permanent Earth Ground
Using the HP E8400A Mainframe 15Chapter 1
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.
Positioning the
Mainframe for
Adequate Cooling
VXI instruments are cooled by air drawn through the back of the mainframe
and exhausted out the sides. The power supply is cooled by air drawn from
the right side (facing the mainframe) and exhaused out the left side. When
placing the mainframe on a work bench or if the mainframe is rack mounted,
provide at least a one inch clearance at the back and sides to allow for proper
air flow.
Installing VXI
Instruments
The HP E8400A mainframe has 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
functionality 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 E6232/E6233 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 instruments which access the backplane local bus
should be installed in adjacent slots.
Note Hewlett-Packard VXI Installation Consultant (HP VIC) is an
excellent tool for installing and configuring VXI systems. The
program guides you through hardware installation, driver
installation, and system self-test. HP VIC is available on the World
Wide Web starting at http://www.hp.com/go/inst_drivers.
Installing C-Size
Instruments
Figure 1-4 shows the installation of C-Size instruments.
16 Using the HP E8400A Mainframe Chapter 1
1. To prevent damage to the VXI instruments, install the instruments
when power is not applied to the mainframe.
2. Insert the instrument into the mainframe by aligning the instrument
with the card guides inside the mainframe. Slowly push the
instrument into the slot until it seats in the backplane connectors. The
front panel of the instrument should be even with the front edges of
the mainframe.
3. Tighten the retaining screws on the top and bottom of the module.
WARNING All instruments within the VXI mainframe are grounded through
the mainframe chassis. During installation, tighten the
instrument's retaining screws to secure the instrument to the
mainframe and to make the ground connection.

Using the HP E8400A Mainframe 17Chapter 1
Installing A- and B-Size
Instruments
A-, B-, and C-size instruments can be installed in the mainframe. A- and
B-size instruments are installed using a module carrier:
•HP E1403B A/B-size Module Carrier extends the P1 connector on
the VXIbus backplane and mounts the (A/B-size) modules flush with
C-size modules. This carrier is recommen ded for Hewlett-Packard
B-size, slave-only devices which have the P1 connector.
•HP E1407A A/B Module Carrier extends the P1and P2 connectors
on the VXIbu s backplane. This carrier is r eco mmended for B-Size,
slave-only devices which have the P1/P2 connectors.
Figure 1-5 shows the installation of A- and B-size instruments.
