Mainframe Description

The HP E1401B mainframe is desi gned in full compli ance with the VXIbus
specification (Rev. 1.4) and VMEbus system specification (Rev. C.1). The
mainframe contains 13 slots for plug-in modules and can be rack mounted
in either the forward or reverse position.

•Improved Power Supply Reliability

•Solid state automatic bus grant sensing to bypass empty slots.

•Variable speed fan cooling.

•Rear mounted 25-pin D connector for auxiliary power supply

monitoring.

•Easy replacement of major components - most can be replaced from

the rear of the mainframe, even while the mainframe is mounted in a
rack.

Chapter 1

Using the Mainframe

•Seven standard VXIbus power supply voltages - all overvoltage,

overcurrent, and temperature prot ect ed.

•Maximum Usable Power (total power supply output power before

thermal protection shutdown): 900 W @25°C, 800W @ 40°C,
650 W @ 55°C.

Line Voltage and Input Power

The HP E1401B mainframe includes a power supply which automatically
adjusts for standard nominal line voltages of 100/120 VAC and 220/240
VAC, and nominal power line frequencies of 50 Hz and 60 Hz. The power
supply has a power factor corrected input section and thus can be powered
from any nominal line input over the range of 100 VAC to 240 VAC. The
power supply can also be powered fro m a 400 Hz AC li ne fr equency or DC
power line voltages. Refer to Appendix A for complete input power
specifications.

WARNING Refer to “HP E1401B Safety Grounding Information” on page 17

for complete grounding information when power line
frequencies exceed 66Hz.

Using the Mainframe 9Chapter 1

Air Flow

The air flow into the plug-in module slots in the HP E1401B mainframe is
significantly more than previous HP mainframes. The mainframe supplies
each of the 13 slots with enough air to coo l 60 Watts while maintaining only
a 10°C rise across a typically de nse module. Up t o 75 Watts per slot may be

dissipated if a 15°C rise is acceptable across a typically dense module. The
graph of Figure 1-1 shows t he air flow volume (l iters/second) versus change
in pressure across the module (mm H

O) for the mainframe.

2

Figure 1-1. Minimum Airflow Available Per Slot

The mainframe has a fan chambe r wi th three circulation fa ns. The speed of
the fans is controlled by the ambient temperature of the air drawn into the
mainframe. Air from the fan chamber is fo rced int o the compar tmenta lized
plenum at the bottom of the mainframe. Although the plenum does contain
a compartmentalized str ucture, some air flow is always present in each of the
13 slots even if one of the three mainframe ci rculation fans fails to operate.
The air passes through the installed modules and escapes out the sides and
top of the main frame.

If any plug-in module exceeds 40 Watts dissipation, you must provide a
minimum of 20 mm (0.8 in) of clearance above the mainframe.

A fourth fan provides cool ing fo r the powe r supply . This fa n is mounte d on
the side of the mainframe.

Caution When installing the mainframe in your system, ensure that the

air inlets and outlets are not obstructed. This prevents damage
to the mainframe and installed modules due to overheat ing.
Clean the air filter regularly.

10 Using the Mainframe Chapter 1

V ariable Speed Fan Normally, the speed of the four internal circulation fans is determined by the

ambient temperature of the air drawn into the mainf rame. One fan cools t he
power supply module an d three f ans cool t he VXI modules inserte d into th e
mainframe. You can override the temperature-controlled speed of the fans
by changing the p ositi on of the F an Speed Con trol Switch on th e rea r of the

mainframe to “HIGH”. This forces all four fans to remain at full speed all of
the time. The two fan modes are:

•Variable Speed Mode (factory default): Quiet operation (~75%

airflow) at <30°C ambient temperature. High speed operation at
>40°C ambi ent temperature.

•High Speed Mode (swi tch selectable): Full airflow at all times.

Figure 1-2. Forcing the Fan to High Speed

Using the Mainframe 11Chapter 1

Rear Panel Auxiliary Connector

A 25-pin “D” connector is provided on the rear panel of the mainframe to
allow monitoring of po wer supply voltages and other functions. The pinouts
for this connector are shown in the following table.

12 Using the Mainframe Chapter 1

+5V The +5 volt output lets you power external TTL circuitry if required. The

maximum current allowed from this supply is 1.0A.

+12V The +12 volt output lets you power a battery charging circuit to provide a

source for the +5 V STDBY input. The maximum cu rrent all owed from t his
supply is 1.0A.

+5V STDBY This provides an input to the mainframe backplane for a +5 volt standby

power source. This may be from a separate battery or power supply. The
maximum current input allo wed is 1.0A. This means that all of the s tan dby
circuitry in all of the modul es mounted i n the mainfr ame can draw a tota l of

1.0A when active.

SYSRESET* This pin provides an exte nsion of the backpl ane SYSRESET* s ignal . It ca n

be used to monitor for SYSRESET* or to send SYSRESET* to the
backplane. Shorting this line to ground inputs a SYSRESET* signal to the
system. If you use any extens io n cable out of the 25-pin D connec tor on the
mainframe rear panel, make certain that you do not violate VXI backplane
electrical sp ecifications (i.e. keep the cable as short as possible, or buffer th e
signal, etc.).

ACFAIL* This pin lets you monitor the ACFAIL* signal from the backplane. Since

this pin is connec ted directly to the backplan e, do not violat e VXI backplane
electrical sp ecifications (i.e. keep the cable as short as possible, or buffer th e
signal, etc.).

EXHAUST_TEMP This pin provides an analog output that is proportional to the power supply

exhaust temperature. Using this circuit, you can monitor the actual
temperature of the power supply exhaust temperature to receive a warning
signal that the ma inframe is runn ing under abnormal conditions. Th is output

provides 0Vdc at 0°C, with a rise of 10mV per degree centigrade when
referenced to chassis ground.

Using the Mainframe 13Chapter 1

Remote Standby

Switch

The remote standby switch connection is provided to let you turn the
mainframe ON or put it in STANDBY mode remotely. These two
connections are wired in parallel with the front panel ON/STANDBY
switch. This means that the front panel switch must be in STANDBY
position for the remote switch to function correctly.

Figure 1-3. Remote Standby Switch Wiring

If you wish to completely disable the front panel switch, you can remove
R93 (a surface mount, zer o-Ohm resistor) on the ba ck of the backplane PCA.
Figure 1-4 shows the loc ation of this resist or. Once R93 is removed, th e only
way to control power is through a switch connected to pins 5 and 18 of the
25-pin D connector on the rear panel of the mainframe. To access the
interface board, remove the power supply.

Figure 1-4. Location of R93 Surface Mount Resistor

14 Using the Mainframe Chapter 1

Installing the Power Line Fuse

The mainframe is shipped with a 15A fast blow (15AF) fuse (HP Part
Number 2110-0054) already installed. This fuse is suitable for all line
voltages. Figure 1-5 shows how to replace the fuse if necessary.

Figure 1-5. Replacing the Power Line Fuse

WARNING For continued protection against fire hazard, replace fuse only

with fuse of specified type and current rating.

AVERTISSMENT Pour ne pas compromettre la protection contra le risque

d’incendie, remplacer le fusible par un fusi ble de mêmes type et
courant nominal.

** Uncertainty in shutdown is due to variable loading. Heavy loading on +5V, -2V, and

-5.2V will cause shutdown at the lower edge of the band. Heavy loading of the +12V,

-12V, +24V, or -24V will cause shutdown at the higher edge of the band. Low line
voltage (90Vac) will cause shutdown at the lower edge of the band.
