  • Page 9: Using The Mainframe

    Chapter 1 Using the Mainframe Mainframe Description The HP E1401B mainframe is designed in full compliance 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.

  • Page 10: Air Flow

    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 cool 60 Watts while maintaining only a 10°C rise across a typically dense module.

  • Page 11: Variable Speed Fan

    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 fans cool the VXI modules inserted into the mainframe.

  • Page 12: Rear Panel Auxiliary Connector

    Rear Panel Auxiliary Connector A 25-pin “D” connector is provided on the rear panel of the mainframe to allow monitoring of power supply voltages and other functions. The pinouts for this connector are shown in the following table. 12 Using the Mainframe Chapter 1 www.valuetronics.com...
  • Page 13 The +5 volt output lets you power external TTL circuitry if required. The maximum current allowed from this supply is 1.0A. The +12 volt output lets you power a battery charging circuit to provide a +12V source for the +5V STDBY input. The maximum current allowed from this supply is 1.0A.

  • Page 14: Remote Standby Switch

    Remote Standby The remote standby switch connection is provided to let you turn the mainframe ON or put it in STANDBY mode remotely. These two Switch 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.

  • Page 15: Installing The Power Line Fuse

    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.

  • Page 16: Power Cords

    15 A Right Angle Connector Power Cords supplied by HP have polarities matched to the power input socket on the instrument: L = Line or Active Conductor (also called “live” or “hot”), N = Neutral or identified conductor, E = Earth or safety Ground * CSA Certification includes only this power cord.
