Mainframe Descrip tion

The Agilent E1401B mainframe is designe d in full compliance with the
VXIbus specificati on (Rev. 1.4) and VMEbus system specification (Rev.
C.1). The mainframe c ontains 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.

• Var iable 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 protected.

• 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 Agilent E1401B mainframe include s a power supply which
automatically adj usts for standard nominal line voltages of 100/120 VAC
and 220/240 VAC, and nominal power line frequenc ies of 50 Hz and 60 Hz.
The power supply has a powe r factor corre cted input section and thus can b e
powered from any nominal line input over the range of 100 VAC to 240
VAC. The power supply can also be powered from a 400 Hz AC line
frequency or DC power line voltages . Ref er to Append ix A for complete
input power specifications.

WARNING Refer to “Agilent E1401B Safety Grounding Information” on

page 17 for complete grounding information when power line
freq u en cies ex ceed 66Hz .

Air Flow

The air flow into the plug -in module slots in t he Agilent E1401B mainframe
is significant ly more than previous Agi len t ma inf ram es . Th e main fra me
supplies each of the 13 slots with enough ai r to cool 60 Watts while
maintaining only a 10°C rise across a typic ally dense module. Up to 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 the air flow volume
(liters/second) versus change in pressure across the module (mm H

the mainframe.

O) for

Figure 1-1. Minimum Airflow Av ailable Per Sl ot

The mainframe has a fa n chamber with three circ ulation fans. The spe ed of
the fans is controlled by the ambient temperature of the air drawn into the
mainframe. Air from the fan chamber is forced into the compartmentalized
plenum at the bottom of the mainf rame. Although the plenum does contain
a compartmentalized structure, some air flow is always present in each of the
13 slots even if one of the three mainf r ame circulation fans fails to operate.
The air passes through the insta lled modules and escapes out the sides and
top of the mainf ram e.

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 fa n provides cooling for the power supply. This f an is mounted on
the side of the mainframe.

Caution When installi n g th e mainfram e i n yo u r system, en sure that the

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

10 Using the Mainframe

Chapter 1

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

ambient temperature of the air drawn into the mainframe. One fan cools the
power supply module and three f ans c ool the VXI mo dules ins erted in to the
mainframe. You can override the tempe rature-controlled speed of the fans
by changing the position of the Fan Speed Control S witch on the rear 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 temper ature. High speed operation at
>40°C ambient temperature.

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

Using the Mainframe 11

Rear Panel Auxiliary Connector

A 25-pin “D” connector is provided on the rear panel of the mainframe to
allow monitoring of power supply volta ges and other func tions. The pin outs
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 +5V STDBY input . T he maximum c urrent allowe d from thi s
supply is 1.0A.

+5V STD B Y This provides an input to the mainframe backplane for a +5 volt standby

power source. This may be from a separate batte ry or power supply. The
maximum current input allowed is 1.0A. This means that all of the standby
circuitry in all of the module s mounted in the mainfra me can dra w a total of

1.0A when active.

SYSRESET* This pin provides an extension of the backplane SYSRESET* signal. It can

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 extension cable out of the 25-pin D connector on the
mainframe rear panel, make cert ain that you do not violate VXI backplane
electrical specifications (i.e. keep the cable as short as possible, or buffer the
signal, etc.).

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

this pin is conne cted direc tly to the ba ckplane, do not violate VXI backplane
electrical specifications (i.e. keep the cable as short as possible, or buffer the
signal, etc.).

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

exhaust temperatur e. Using this circuit, you can monitor the actual
temperature of the power supply exhaust temperature to receive a warning
signal that the mainframe is r unning under abnormal condi tions. This outp ut
provides 0Vdc at 0°C, with a rise of 10mV per degree centig rade when
referenced to chassi s ground.

Chapter 1

Using the Mainframe 13

Remote Standby

Switch

The remote standby switch connec tion is pr ovided 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, zero-Ohm resistor) on the back of the backpla ne PCA.
Figure 1-4 shows the l ocation of this re sistor. Once R93 is removed, t he only
way to control power is through a switch conne cted 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.

Chapter 1

Installing the Power Line Fuse

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

* Per VXI Specification rev. 1.4

** 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.

Humidity Exceeds MIL-T-28800D test limit 3.7.2, 40 ºC and 95% RH.

Temperature Range Exceeds MIL-T-28800D Test Limits 3.7.2,

Non-operating:-40ºC to +75ºC
Operating: 0ºC to 55ºC

Shock and Vibration Meets the following MIL-T-28800D Test Limits:

V ibration test limits: 3.7.4.1 and 4.5.5.3.1
Shock Test Limits: 3.7.5.1 and 4.5.5.4.1
Bench handling test limits: 3.7.5.3 and 4.5.5.4.3

Cooling Provided

Fan set to "Variable": Quiet operation (approximately 75% airflow)

at <30ºC ambient temperature and high speed oper ation at >40ºC
ambient temp e rat ure.

Fan set to "HIGH": Full airflow all the time.

For modules with typical density:

10ºC rise at 60W per slot
15ºC rise at 75W per slot

Acoustical Noise Low fan speed: 48 dBA sound pressure at bystander position.

Lpa = 48 dB fiktiver Arbeitsplatz, normal ier Betrieb, nach DIN 45635 T.1

High fan spe ed: 56 dBA sound pressure at bystander posit ion.

Lpa = 56 dB fiktiver Arbeitsplatz, normal ier Betrieb, nach DIN 45635 T.1

Classification Classified under MIL-T-28800 as Type III, Class 5, Style E, Color R.

EMC Testing Withi n the requirements of MIL-STD-461 methods CE01, CE02
