The screen will display the Mainframe Test menu. 7 Select Option Board Test, then select Run. If an HP 16501A expansion frame is not connected, then expect a "No Expansion Card Present" message to appear when you run the Option Board Test. Refer to the HP 16500B/16501A Service Guide for more information about the expansion frame. Servicing the Interface Module Verify the Interface Module Performance 8 Verify that the tests pass. If all of the tests pass, then go to the step 9. If any of the tests fail, then LAN hardware or the interface module is suspect. • To verify the LAN hardware, perform the following checks: Check that the LAN cable is properly seated at both the interface module and at the client/server/router ends. Check that the LAN cable is good and that all signal lines in the cable have electrical integrity. • To replace a defective interface module, refer to "Removing and replacing the interface module," later in this chapter. 9 Exit the Test System. a Touch the Module field, then touch Test System. b Touch the Menu field, then touch Exit Test. c Touch the field near the center of the screen to exit the test system and to load the operating system. 3-6 Servicing the Interface Module Troubleshooting an HP 16501A Expansion Frame Troubleshooting an HP 16501A Expansion Frame For details on troubleshooting a system that is connected to an HP 16501A Expansion Frame, refer to the HP16500B/16501A Logic Analysis System Service Manual. If you suspect that the HP 16500H Interface Module is defective, use the procedures in this chapter to verify the interface module performance and, if necessary, replace the hardware. The expnasion frame is recognized by the mainframe if the "Master Frame" text on the left side of the mainframe power-up screen appears as a blue user-select field. If the text does not appear as a blue field, the most likely cause is a defective interface module. Servicing the Interface Module Troubleshooting in an Ethernet LAN Environment Troubleshooting in an Ethernet LAN Environment For details on troubleshooting a system that is connected to an Ethernet LAN, refer to the HP16500H LAN Administrator’s and Service Guide. If you suspect that the HP 16500H Interface Module is defective, use the procedures in this chapter to verify the interface module performance and, if necessary, replace the hardware. Servicing the Interface Module Troubleshooting in the HP 16505A Prototype Analyzer Environment Troubleshooting in the HP 16505A Prototype Analyzer Environment For details on troubleshooting a system that is connected to an HP 16505A Protoype Analyzer, refer to the HP16505A Prototype Analyzer Service Guide. If you suspect that the HP 16500H Interface Module is defective, use the procedures in this chapter to verify the interface module performance and, if necessary, replace the hardware. Servicing the Interface Module Removing and Replacing the HP 16500H Interface Module Removing and Replacing the HP 16500H Interface Module 1 If the HP 16500B Logic Analysis System is connected and mounted to a LAN, then unmount the HP 16500B file system. Unmounting from a LAN You must unmount the HP 16500B before power is removed from it. Then, you can mount the HP 16500B 15 seconds after the System Configuration menu is displayed when powering up the instrument. You can write a network script that executes an unmount and mount procedure. 2 If the HP 16500B Logic Analysis System is being used in the HP 16505A prototype analyzer environment: a Save all work and close all windows. b Open the Session Manager window, then select Power Down. c Remove power from the HP 16505A Prototype Analyzer, then remove power from the HP 16500B mainframe. d Disconnect the HP 16505A interface cable, HP 16501A interface cable, and LAN cable from the interface board. 3 Turn off the power switch located on the front panel of the HP 16500B mainframe and the standby switch located on the rear panel. Then, unplug the power cord from the mainframe. Refer to the HP 16500B Service Guide if you need instructions for removing and replacing parts of the HP 16500B. 3 Remove the two rear feet on the top and the top cover of the HP 16500B mainframe. 4 On the interface module, disconnect the cable from the CPU board. 3-10 Servicing the Interface Module Removing and Replacing the HP 16500H Interface Module 5 Remove the screws connecting the interface module to the mainframe. Two screws through the top of the interface module connect it to the sheetmetal plate, and four screws connect the rear plate of the interface module to the rear panel of the mainframe (see the figure below). Removing the Interface Module Servicing the Interface Module Removing and Replacing the HP 16500H Interface Module 6 Install the new interface module by reversing this procedure. 7 Test the performance of the interface board. Refer to "Verifying the interface module performance" in this chapter for the performance verification test procedure. 8 Reconnect the HP 16505A or ...
