The designation HP E840xA refers to both VXI mainframes.
Preparing Your VXI System for Use The HP E840xA mainframes are shipped from the factory 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 with a power cord and with a fuse installed in the power supply.
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 shown in Figure 1-1. The wire must be green with a yellow stripe, or bare (no insulation). Use a m4 x 10 screw, grounding lug, and toothed washers (or toothed lug) as shown in the Figure. 2.
Installing VXI Instruments 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.
Installing C-Size Instruments Figure 1-2 shows the installation of C-Size instruments. seat the module by pushing in the extraction levers retaining screws extraction levers slide the module into the mainframe until it plugs into the backplane connectors Figure 1-2. Installing C-Size Instruments in the HP E840xA Mainframe WARNING Chapter 1 All instruments within the VXI mainframe are grounded through the mainframe chassis.

Chapter 1 +5VC (pin 6) The +5 volt output allows you to power external TTL circuits if required. The maximum current allowed from this supply is 1.0A +12VC (pin 7) The +12 volt output allows you to power external circuits, charge a battery, or power relays if required. The maximum current allowed from this supply is 1.0A +5V STDBY (pins 8, 21) This provides an input to the mainframe backplane for a +5V DC standby power source. This may be from a separate battery or power supply.
Using the Remote Power-On Pins The remote power-on pins (pins 5 and 18) of the Diagnostic Connector 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. 0Ω Resistor Figure 1-5. Remote Standby Switch Wiring.
Disabling the On/Stdby Switch The front panel On/Stdby switch is disabled by removing surface mount 0Ω resistor located on the front monitor board (see Figure 1-6). The resistor is labeled: REM PWR JUMPER. Location of 0Ω resistor Figure 1-6. Disabling the On/Stdby Switch Caution After removing the 0Ω resistor, heat damage may prevent the resistor from being re-installed to re-enable the On/Stdby switch. To access the basic monitor board and resistor: 1. Turn off the mainframe and remove the power cord.
4. 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. 5. Save the resistor in order to re-enable the On/Stdby switch. Again, heat damage may prevent the resistor from being re-installed. 6. Replace the mainframe cover and rear panel.
