VXT 2000 Windowing Terminal Service Guide 5 A Look at the Terminal 1.3 Operating Features 1.3 Operating Features This section briefly describes terminal sessions, network protocols, and how to control feature settings on the terminal. 1.3.1 X Window Sessions and Terminal Window Sessions The terminal allows you to open two types of sessions on host computers: X window sessions and VXT DECterm terminal window sessions. X Window Session To run an X window session, you log in to a host that has X window applications. You can have one X window session and several VXT DECterm terminal window sessions open at the same time. Within the X window session, you can run multiple X window clients. Each X window session and terminal window session appear in a separate window. Terminal Window Session The terminal has a VXT DECterm terminal emulator that allows you to log in to a host as you would on a conventional video terminal. VXT DECterm windows are compatible with VT300 series text terminals and offer enhancements such as user-selectable fonts. 1.3.2 Network Communication Protocols You can use the terminal with VMS, ULTRIX, or UNIX operating systems. You can run video terminal sessions and X window sessions on any of these operating systems. For UNIX and ULTRIX systems: The transmission control protocol/Internet protocol (TCP/IP) is the communication protocol. The terminal can use the TCP/IP Telnet or LAT communication protocols to make terminal window connections to UNIX and ULTRIX host systems in a wide-area network. For VMS systems: The LAT protocol is the communication protocol. For InfoServer systems: The terminal uses the LASTport protocol for InfoServer systems. 6 Chapter 1 A Look at the Terminal 1.3 Operating Features 1.3.3 Terminal Software The terminal downloads its VXT system image software from a host or an InfoServer. The InfoServer provides these added capabilities: · Memory paging · Configuration and font management for groups of terminals 1.3.4 Customizing the Terminal There are several ways to check and control the terminal's operating features. · Terminal Manager Customize menu When you click on Customize in the Terminal Manager window, the Customize menu appears. This menu lets you change many of the terminal's operating features, such as the keyboard setup, the display language, and the cursor style for the pointer (mouse). You can also customize boot and X server settings. If you have a DECimage 2000 module installed and want to use XIE applications, you must customize X server settings to enable XIE (Section 2.1.5). · VXT DECterm Options menu When you create a Telnet, LAT, or serial port terminal window, the terminal displays a VXT DECterm window. The window includes an Options menu that lets you change certain terminal window features while an application is running. Many applications handle customization of the terminal window. · Window Manager Options menu When you click on the window menu button in any window, the window manager displays a window menu. From the window menu, you can choose an Options submenu that lets you customize many window management features. · Configuration Manager window Terminals that use VXT server-based software from an InfoServer have a configuration manager. When you click on Configuration... in the Terminal Manager window's Customize menu, the terminal displays a Configuration submenu. From this submenu, you can access the Resource Management and Font Management dialog boxes. VXT 2000 Windowing Terminal Service Guide 7 A Look at the Terminal 1.3 Operating Features 1.3.5 Checking the Terminal's System Configuration From the Terminal Manager window, you can display a System Configuration dialog box to quickly verify many of the terminal's customizable configuration settings, such as the VXT system image, the work group, and the Ethernet address.

To troubleshoot the terminal, refer to Chapter 4. 3.1 Self-Tests The terminal has a series of self-tests to help you isolate failures to faulty device and field replaceable units (FRUs). You can run self-tests in two ways. · Automatically during power-up · Manually in console mode The terminal automatically runs initialization self-tests during power-up. During the power-up process, the diagnostics test the basic functions of all FRUs. If the diagnostics detect an error, they continue testing (if possible) until finished, then report any errors. You can configure the terminal to run a minimal or extended power-up self-test at power-up by entering a command in console mode. You can also run self-tests manually in console mode. VXT 2000 Windowing Terminal Service Guide 19 Testing 3.1 Self-Tests 3.1.1 Running Self-Tests in Console Mode Table 3-1 lists the power-up self-tests that run each time you turn on the terminal's power switch. To enter console mode: Press the halt switch on the rear panel of the terminal. When you enter console mode, the terminal resets itself and quits all session activity. mode. The system displays the >>> console prompt. ------------------------------------------------------------ Note ------------------------------------------------------------ Before running tests in console mode, enter the UNJAM command at the console prompt to clear all pending interrupts. ------------------------------------------------------------ To choose a minimal or extended power-up self-test: To run a minimal self-test automatically at power-up, enter the following command: >>> SET FBOOT 1 To run the extended self-test automatically at power-up, enter the following command: >>> SET FBOOT 0 To run self-tests individually: You may want to run self-tests at a time other than power-up. You can run individual tests or a range of test with TEST command. Use the test numbers listed in Table 3-1. For example, to run all self-tests, enter the following command: >>> TEST 1:12 Table 3-1 Power-Up Self-Tests ------------------------------------------------------------ Device Number Device Test Number ------------------------------------------------------------ 1 NVR test T 1 2 Video (monochrome) T 2 (continued on next page) 20 Chapter 3 Testing 3.1 Self-Tests Table 3-1 (Cont.)

You can also check the software version by viewing the System Configuration dialog box (Section 1.3.5). 3.3 Network Service Failure Messages The terminal may experience network problems even though the power-up self-tests finish successfully. Network problems may occur because vital network services failed. If the network fails, the terminal may display one of the following network service failure messages at the top of the screen: Cannot locate system image, retrying ... Cannot connect with system image, retrying ... Cannot locate free pagefile storage, retrying ... Cannot locate pagefile, retrying ... Cannot connect with pagefile, retrying ... Cannot extend pagefile, more disk space is needed on server If a network error occurs, contact the system manager or the Digital network service representative. 3.4 Checking for Memory Errors The terminal displays memory status messages under certain conditions. You can also check for soft memory errors in console mode. 3.4.1 Memory Status Messages The terminal reports memory status or potential memory problems in the Messages box of the Terminal Manager window (Figure 3-1) when the terminal is using the host-based VXT system software. Table 3-3 describes possible memory status messages. VXT 2000 Windowing Terminal Service Guide 25 Testing 3.4 Checking for Memory Errors Table 3-3 Memory Status Messages ------------------------------------------------------------ Status Message Description ------------------------------------------------------------ Memory Not Low There is enough memory for the terminal to perform normal operations. The terminal displays a Memory Not Low message in the Terminal Manager window. Memory Low If the memory level continues to decrease, then the local VXT DECterm windows and remote client sessions may fail. The terminal continues to operate normally in this state. Memory Very Low If the memory level continues to decrease, then all terminal operations may fail. If the memory condition becomes Very Low when the terminal is servicing an X protocol request from a remote client, the request fails and the terminal disconnects the session to the remote client immediately. The terminal will not service any new X session requests, but all other operation continue normally. No Memory Left If there is no memory left, all terminal operations may fail until the user clears the No Memory Left condition. The terminal does not display any warning messages and operates as though it is in the Memory Very Low condition. If the terminal cannot recover enough memory to operate normally, the terminal restarts itself. ------------------------------------------------------------ 3.4.2 Soft Error Messages If you suspect that the customer has a memory problem, such as not being able to run an application that ran previously, enter the following console command: >>> SHOW ERROR The SHOW ERROR command displays any soft error message along with other errors. See Chapter 4 to troubleshoot either hard or soft errors. 3.5 Screen Alignment Patterns You must use screen alignment test patterns to make all video adjustments. See your monitor 's service guide for alignment procedures. To display a test pattern, you use screen alignment test patterns menu in console mode. To enter console mode, you press the halt switch on the rear panel of the terminal (System Box Connectors and Switches). When you enter console mode, the terminal quits all session activity and performs a software reset. To view the screen alignment test patterns menu, enter the following command at the >>> console prompt: >>> T/UTIL 2 26 Chapter 3 Testing 3.5 Screen Alignment Patterns From the menu, choose the alignment pattern that you will be using for video alignment. To return from a display pattern to the menu, press the space bar. To return to the console prompt, press ------------------------------------------------------------ ------------------------------------------------------------ Ctrl ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ C ------------------------------------------------------------ ------------------------------------------------------------ . VXT 2000 Windowing Terminal Service Guide 27 4 ------------------------------------------------------------ Troubleshooting This chapter describes how to troubleshoot hard and soft errors on the VXT 2000 and DECimage 2000 windowing terminals by · Using error codes displayed on the screen (Sections 4.4 and 4.5) · Using error codes displayed by the LEDs (Sections 4.4.1 and 4.6) · Checking a table of general problems (Section 4.7) 4.1 Troubleshooting Sequence When troubleshooting the terminal, use the following sequence: 1. Check the console error codes. 2. Check the LED error codes. 3. Check the troubleshooting table in this chapter. Example Suppose the video module is loose. 1. There are no console error codes, because the video display is not working. 2. There is no LED error code, because the LEDs may be running through the test sequence. 3. Check Table 4-11 for a screen display problem that matches the symptoms of your terminal. 28 Chapter 4 Troubleshooting 4.1 Troubleshooting Sequence ------------------------------------------------------------ Symptom Screen Display Problems Suggested Solutions ------------------------------------------------------------ Monitor 's power LED is on, but no video is displayed, and the system box LEDs are blinking. Check for a loose video module (Section 5.6). ------------------------------------------------------------ 4. Follow the suggested solutions in the order listed in the table. 4.2 Before You Start The following information will help you troubleshoot the terminal easily and effectively: ------------------------------------------------------------ WARNING ------------------------------------------------------------ If you smell burning components, turn off the monitor 's power switch and terminal's power switch off, then unplug the power cord. ------------------------------------------------------------ · If you are going to service a display problem, ask the customer to warm the monitor up for at least 20 minutes before you arrive, if possible. · Magnetic fields affect monitor performance and can give a false indication of a monitor failure. Place the monitor away from any electromagnetic devices (such as printers and terminals) or large magnetized objects (such as filing cabinets and steel beams in walls). 4.3 Hard and Soft Errors The terminal's power-up tests and self-tests can detect hard errors and soft errors. · Hard errors are fatal errors that force the terminal to quit all session activity and enter console mode. · Soft errors can be fatal or nonfatal errors. Nonfatal errors do not interrupt session activity. Fatal soft errors can occur during customer service mode. Many memory errors may be soft errors, because the terminal can operate as a server-based machine. VXT 2000 Windowing Terminal Service Guide 29 Troubleshooting 4.3 Hard and Soft Errors 4.3.1 Entering Console Mode After a Hard Error If a self-test detects a hard error on a networked terminal, the terminal automatically enters console mode and displays the >>> console mode prompt. In console mode, you can use the SHOW ERROR and SHOW MEM commands to display error information. 4.4 Troubleshooting Soft Memory Errors The self-tests report many memory errors as soft errors. When a self-test finds a soft memory error, the terminal still indicates the self-test was successful. To troubleshoot soft memory errors, you need to display the memory positions and gaps so you can determine which FRU to replace. Therefore, you must correct any video problems before trying to correct any soft memory error. To display soft errors: Normally, the terminal does not display soft memory errors, except during the self-tests. You can use the SHOW ERROR console command to display any soft errors and other errors. Example--Troubleshooting Soft Memory Errors To determine if the self-tests detected a memory error: 1. Enter console mode by pressing the halt switch on the rear of the system box. 2. Enter the SHOW CONFIG command to determine the memory in the system. The display will show memory locations for components, such as those shown in Figure 4-1. 30 Chapter 4 Troubleshooting 4.4 Troubleshooting Soft Memory Errors Figure 4-1 Sample Configurations--12 MB and 6 MB Systems Each 2 MB memory (MEM) option occupies a 1fffff segment of memory. Each 4 MB MEM option occupies a 3fffff segment of memory. In SHOW CONFIG displays, the slot locations S[0], S[1], and S[2] correspond to locations J1, J2, and J3, respectively, on the memory controller module. If the SHOW CONFIG command shows a 2 MB MEM at S[0] and a 4 MB MEM at S[1], the memory map is as follows: 000000 3fffff 4K bytes for the system logic module 400000 5fffff 2K bytes for the memory controller module 600000 7fffff S[0] (2MB MEM) 800000 Bfffff S[1] (4MB MEM) The MEM cards can be any combination of 4 and 2 MB MEM cards. The only restriction is that you must load the MEM slots starting with S[0] and progressing to S[2]. If there is an empty slot between MEMs, the self-tests report a hard memory error. 3. Enter the SHOW ERROR command at the console prompt. If the self-tests detect a memory error, the console displays a memory error code beginning with a question mark. For example: ?001 005 MEM nnn ? indicates a soft error. 001 indicates a field replaceable unit--the system logic module. 005 indicates the device that failed--memory. MEM indicates a memory error. nnn indicates where the memory error occurred. VXT 2000 Windowing Terminal Service Guide 31 Troubleshooting 4.4 Troubleshooting Soft Memory Errors 4. Enter the SHOW MEM command to determine the areas of memory. This command displays any valid gap in the memory areas, as well as any bad memory area. A valid gap in memory is space reserved for future memory expansion. Examples · If the terminal has a valid gap in memory and the maximum memory is 6 megabytes (MB), then the SHOW MEM command may display the following information: 200000 3fffff 5dffff 5fffff - 200000 - 3fffff is a valid gap for a system logic module that has 2 MB of resident memory (Figure 4-2). This gap will not exist with a system logic module that has 4 MB of resident memory. - 5dffff - 5fffff is the scratch RAM area. Scratch RAM is 128K bytes of memory reserved for booting, always positioned at the top of memory. As more memory modules are installed, these numbers increase to occupy the last 128K bytes in memory. Figure 4-2 Example of 6 MB System with Soft Memory Error 32 Chapter 4 Troubleshooting 4.4 Troubleshooting Soft Memory Errors · If the terminal has bad memory and the top of memory is 6 MB, then the SHOW MEM command may display the following information: 200000 3fffff 41ffff 42ffff 5dffff 5fffff ------------------------------------------------------------ 200000 - 3fffff is the valid gap on the system logic module. ------------------------------------------------------------ 41ffff - 42ffff is not normal for a 6 MB system. These numbers represent the bottom and top, respectively, of the bad memory area. ------------------------------------------------------------ 5dffff - 5fffff is the scratch RAM area at the top of memory. 5. By analyzing the memory data, you can determine the valid gaps, the scratch RAM area, and any bad memory data. By comparing the memory data with the configuration, you can determine which FRU is showing the soft bad memory error. · In Figure 4-2, the bad memory area (41ffff - 42ffff) is within the memory configuration area of 400000 - 5fffff. This area is the resident 2 MB RAM on the memory controller module, so the memory controller module should be replaced. 4.4.1 Troubleshooting Soft Memory Errors by LEDs When self-tests find the first soft error, the memory test displays the soft errors on the screen (Table 4-1). The diagnostic LEDs on the system box momentarily display the memory test error code (Section 4.6). 4.5 Troubleshooting Hard Errors If the terminal's self-tests find an error, the terminal attempts to display an error code on the screen and a device code on the diagnostic LEDs. Table 4-1 lists the error codes reported on the screen. If the video fails, refer to Section 4.6 to read the error code from the LEDs. To troubleshoot hard errors: 1. At the >>> console prompt, enter the SET FBOOT 0 command. This command sets the self-test mode to non-fastboot, so the terminal tests all resident memory. 2. Record any screen error code. If the video failed, record any LED device code. Normally, the terminal does not display a code for soft memory errors. If you suspect a soft memory error, see Section 4.4. VXT 2000 Windowing Terminal Service Guide 33 Troubleshooting 4.5 Troubleshooting Hard Errors 3. Check Table 4-1 for screen error code you recorded, to determine if the error is a device error. If the video failed, check the tables in Section 4.6 for your LED device code. For a detailed description of the error codes, see Appendix C. Example--Troubleshooting Hard Errors For hard errors, the power-up self-tests may report the following information: VXT V01.nnn ROM version nn-nn-nn-nn-nn-nn The terminal's Ethernet address 2MB Megabytes of memory installed ?? 001 9 VNI 0168 Error for disconnected network cable. ?? 003 3 QDZ 0096 Other error messages (See Figure 4-3 and Table 4-1.) Self-test progress indicator (Fills in as tests are completed.) Figure 4-3 shows the format of an error message. Figure 4-3 Error Message Format Table 4-1 lists possible error codes. The probable solution for any error code not listed in the table is to replace the system logic module.
