Detailed information on installing and troubleshooting in the LAN environment is covered in the HP 16500H LAN Administrator’s and Service Guide. The following steps are an overview of the process with some troubleshooting hints. 1 Connect an EtherTwist 10Base-T LAN cable into the RJ-45 LAN port on the interface module. If your LAN uses ThinLAN connections, a Media Access Unit (MAU) is required. 2 Set up the configuration menus on the HP 16500B mainframe. You can configure the interface module to work with your network from the HP 16500B front-panel touchscreen. After the HP 16500B power-up tests are complete, the Ethernet configuration can be accessed in the Communications menu. The interface module automatically obtains the subnet mask by sending a broadcast ICMP query over the network. The broadcast ICMP query is transmitted approximately 10 seconds after power is applied to the interface module and approximately 2 seconds after the IP address is changed. When the query is answered by another network device, the interface module stores the information in internal memory. 2–5 Installing the Interface Module Ethernet LAN Interface 3 Verify connectivity with an echo request. In most network environments, an echo request is accomplished using the ping utility. For the exact syntax for the ping or other echo request utility, refer to your network documentation. A normal response to multiple echo requests is 9, 10, or possibly 11 packets transmitted for every 10 echo requests. If there is no response to the echo request, first check the command line. If an IP address is used in the echo request command line, then the IP address typed in the command line should match the IP address stored in the HP 16500B Ethernet Configuration menu. If a hostname was used in the command line, then check the node names database to see that the IP address and the hostname for the HP 16500B were correctly entered. After verifying the command line, check to make sure the hardware is connected and operating properly. To verify operation of the interface module, refer to "To verify the interface module performance" in Chapter 3. An intermittent response to the echo request indicates a problem with the LAN itself. Use a LAN analyzer or LAN management software to monitor activity and determine where bottlenecks or other problems are occurring. 4 Mount the HP 16500B system with an NFS mount. An NFS mount of the 16500B system depends on the network environment the system is being mounted to. For UNIX, the mountcommand with the computer name and mount point are required. In MS-DOS, a virtual drive specifier and 16500B IP address are required. File Manager in MS-Windows is used to mount in an MS-Windows environment. In all cases, either the 16500B file server /control or /data directory must be specified depending on whether the 16500B system is being mounted for control or data. The normal response to an NFS mount in most cases is the command line prompt reappears. If the system includes a utility to view the mount table (for example, in UNIX, the mount command alone displays /etc/mnttab), then the 16500B remote file server should appear in the table of mounted devices. If error messages appear, then check the command line syntax. If the syntax is correct, then resolve the error message directly using your network documentation. Note that an error message appears if you try to mount too soon after power-up. You need to wait at least 15 seconds after the System Configuration menu is displayed on the HP 16500B display before attempting to mount. 2–6 Installing the Interface Module HP 16501A Expansion Frame Interface HP 16501A Expansion Frame Interface The interface port for the HP 16501A Expansion Frame permits you to quickly and easily connect an expansion frame to the HP 16500B mainframe. With an expansion frame connected to the mainframe, a total of ten 16500-series measurement modules can be configured and utilized. Detailed service information for the HP 16500B mainframe and 16501A Expansion frame is covered in the HP 16500B/16501A Service Manual. The expansion 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. 2–7 Installing the Interface Module HP 16505A Protoytype Analyzer HP 16505A Protoytype Analyzer The high-speed interface port for an HP 16505A Protoytype Analyzer permits you to connect a Prototype Analyzer to the HP 16500B mainframe. Detailed installation information is covered in the HP 16505A Prototype Analyzer Installation Guide. 2–8 Verifying the Interface Module Performance 3-2 Performance verification procedure 3-3 Troubleshooting an HP 16501A Expansion Frame 3-7 Troubleshooting in an Ethernet LAN Environment 3-8 Troubleshooting in the HP 16505A Prototype Analyzer Environment 3-9 Removing and Replacing the HP 16500H Interface...
