26 Keysight E8491B IEEE 1394 PC Link to VXI User GuideInterface Installation and Configuration Using this ChapterInstalling C-size InstrumentsFigure 2-8 shows the installation of C-size instruments.1 Insert the instrument into the mainframe by aligning the instrument with thecard guides inside the mainframe. Slowly push the instru ment into the slotuntil it seats in the backplane connectors. The front panel of the instrumentshould be even with the front edges of the mainframe.2 Tighten the retaining screws on the top and bottom of the module.Figure 2-8 Installing C-size Instruments.retainingscrewsslide the moduleinto the mainframeuntil it plugs into thebackplane connectorsextractionseat the modulepushing in theextraction leversTo prevent damage to the VXI instruments being installed,remove power from the mainframe or set the power switch toOff or Standby before installing the instruments.All instruments within the VXI mainframe are groundedthrough the mainframe chassis. During installation, tightenthe instruments’ retaining screws to secure the instrumentto the mainframe and to make the ground connection.
