It has four groups of keys, two LED indicators, and two audible indicators--a keyclick and bell. The LK401-XX is the standard version, and the LK402-XX is the word processing version. 1.1.4 Mouse The mouse is a three-button pointing device. The mouse lets you choose items from screen menus or move the cursor to different points on the screen. 1.2 Operating Features This section briefly describes terminal sessions, network protocols, and how to control feature settings on the terminal. 1.2.1 X Window Sessions and Video Terminal Sessions The terminal lets you open two types of sessions on host computers: Video Terminal Session The terminal has a video terminal (VTE) window that lets you log into a host as you would on a conventional video terminal. The terminal's VTE window works like Digital's VT320 terminal. X Window Session The terminal lets you open X window sessions. To run an X window session, you log into a host and use that host's X window software. You can open one X window session and several VTE sessions at the same time. Within the X window session, you can run multiple X window clients. Each X window client and VTE session appears in a separate window. 1.2.2 Network Communication Protocols You can use the terminal with the VMS, ULTRIX, or UNIX operating systems. You can run video terminal sessions and X window sessions on any of these operating systems. For VMS systems: The local area transport (LAT) protocol is the communication protocol. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ 8 Overview of the Terminal For ULTRIX and UNIX 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 video terminal connections to UNIX and ULTRIX-based host systems in a wide-area network. 1.2.3 Customizing the Terminal The terminal has a Terminal Manager window with a Customize menu that lets users view and change the settings of the terminal's operating features. The terminal stores feature settings in nonvolatile RAM (NVR) memory. NVR retains the settings when the terminal is turned off, so the terminal can restore the settings when power is turned on again. The terminal can also restore factory-default settings from program memory (ROM). Before you start a session, make sure you have the font path, group code, and specific addresses in use (Section 5.1). 1.2.4 Overriding Passwords Performing a Secure Reset allows you to override saved passwords. You may need to perform a secure reset if a user locks the terminal's customize dialog boxes, then forgets the customize security password. When you perform a secure reset from the Session pull-down menu, the terminal resets all customized settings to their factory defaults, except the Secure Reset Count. Each time you perform a secure reset, the secure reset count in the Terminal Manager window increases by one. To perform a secure reset, see Section 5.5. 1.3 Site Requirements The terminal requires certain system software and network hardware to operate. The system manager must ensure these requirements are met. An appendix in the terminal's Installing and Using . . . guide describes the required system management tasks for the terminal. Network Hardware Support The terminal requires one of the following physical connections to connect to a host computer system: ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Overview of the Terminal 9 ThinWire connector Lets the terminal operate with X window applications and multiple video terminal (VTE) sessions, using either the LAT or TCP/IP network protocol. You must use the ThinWire connector to operate with X window or DECwindows software. Serial line Lets the terminal connect to a single host or terminal server as a traditional video terminal. System Software Support The following table summarizes the system resources needed to open X window sessions or video terminal (VTE) sessions: ------------------------------------------------------------ Operation Operating System Communication Protocol ------------------------------------------------------------ Video terminal session VMS Version 4.0 or higher LAT ------------------------------------------------------------ UNIX (any version) TELNET (TCP/IP) ------------------------------------------------------------ ULTRIX (any version) UWS Version 2.2 TELNET (TCP/IP) or LAT ------------------------------------------------------------ X window session VMS Version 5.3-1 or higher LAT ------------------------------------------------------------ UNIX (any version) TCP/IP TFTP (UDP) for font service ------------------------------------------------------------ UWS Version 2.1 or higher (includes ULTRIX Version 3.1) TCP/IP TFTP (UDP) for font service ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ 2 Testing ------------------------------------------------------------ This chapter describes how to: · Run the terminal's built-in self-tests and menu-driven diagnostic tests. · Display video alignment patterns on the monitor. · Run remote diagnostic tests on the terminal over the network. · Test the LAT. · Test TELNET and network hardware on UNIX and ULTRIX systems. To test the monitor, see the monitor 's service guide. 2.1 Terminal Self-Tests The terminal has a series of self-tests to help you isolate failures to faulty field replaceable units (FRUs). You can run self-tests in three ways. · Automatically during power-up · Using menu-driven diagnostics · Using remote diagnostics on the network The terminal automatically performs basic self-tests during power-up. You can run more extensive self-tests by using the terminal's Diagnostics dialog box and connecting loopback connectors to specific ports. Remote diagnostics let you test the terminal from a remote host. NOTE Running the menu-driven diagnostic tests resets the terminal and quits all session activity. 10 ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Testing 11 If a test finds an error: 1. Record the error code. 2. Find the error code and suggested solution in Table 3-1. 3. Repeat the tests in this chapter to ensure the terminal operates correctly. The terminal will not service any interrupts or commands, except as necessary to perform testing. 2.1.1 Successful Power-Up Self-Tests Power-up self-tests run each time you turn on the power switch on the system box. There are two levels of power-up self-tests --level 0 and level 1. Level 0 tests run first, followed by level 1 tests. Failure of some power-up tests may prevent the terminals from running. Level 0 Testing When you turn on the terminal, level 0 testing begins. When level 0 testing completes successfully (within 5 seconds), the operating system starts and level 1 testing begins automatically. Table 2-1 lists the eight level 0 tests. Table 2-1 Level 0 Tests ------------------------------------------------------------ Simple CPU test Video control register test ROM checksum test I/O data path test RAM test Illegal monitor test Interrupt test Ethernet port (LANCE) not reset on power- up test ------------------------------------------------------------ Level 1 Testing Level 1 testing begins by displaying various patterns on the screen. Next, a pie graph display appears to indicate the progress of level 1 testing. As each test finishes, a segment of the pie fills in. When level 1 testing completes successfully (within 25 seconds of power- up): · The keyboard bell rings. · The keyboard LEDs turn off. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ 12 Testing · The system logic board LED turns off. · The pie graph is replaced by the Terminal Manager window (Figure 2-1). The Terminal Manager title bar displayed on your terminal indicates the software version running. · The diagnostic summary box in the window contains the message: ------------------------------------------------------------ ------------------------------------------------------------ All Diagnostics Passed ------------------------------------------------------------ ------------------------------------------------------------ Figure 2-1 Terminal Manager Window ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Testing 13 Table 2-2 lists the 15 level 1 tests. Table 2-2 Level 1 Tests ------------------------------------------------------------ Video RAM test DUART1 timer test Video test Keyboard port test NVR checksum test Mouse port test Ethernet address ROM test DUART2 timer test Option RAM test (if present) Ethernet port (LANCE) test Host port test Mouse test Printer port test Keyboard test Image test (if installed) ------------------------------------------------------------ System Logic Board LED Power-Up Sequence When the terminal powers up, the red LED on the system logic board turns on. At the start of level 0 testing, the LED turns off. If level 0 completes successfully, the LED turns on again. The operating system then performs level 1 testing. If level 1 testing is successful, the LED turns off. The following diagram shows the complete sequence: ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ 14 Testing 2.1.2 Menu-Driven Diagnostic Tests Menu-driven diagnostic self-tests let you test each device again after the power-up self-tests are complete. You can test devices individually, a few at a time, or all together in sequence. Use menu-driven diagnostics to: · Perform external loopback testing. · Verify the terminal's operation after making repairs. CAUTION Menu-driven diagnostics cancel current host connections, cause a software reset, and write messages on the screen. Loopback Connectors The loopback test can check the driver and receiver hardware of the following ports on the rear of the system box: ------------------------------------------------------------ Port Loopback Connector Part Number ------------------------------------------------------------ Host port 6-pin loopback connector, MMJ (H3103-00) 12-25083-01 Printer port 6-pin loopback connector, MMJ (H3103-00) 12-25083-01 Mouse port Mouse loopback connector 12-25628-01 Ethernet port Ethernet T-connector (H8223-00) 12-25869-01 with terminators (H8225-00) 12-26318-01 ------------------------------------------------------------ The following figure shows the loopback connectors. Install the appropriate connector on each port you want to test. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Testing 15 To run menu-driven diagnostics: The terminal must complete the power-up self-tests and display the Terminal Manager window. You run menu-driven diagnostic tests from the terminal's Diagnostics dialog box.

ping You can use the UNIX ping command to verify the network hardware, Internet protocol (IP), and ICMP layers. Tracking a single-point hardware or software failure on the Internet network can be difficult. The ping command sends ICMP ECHO_REQUEST packets to network hosts. The ping command utilizes the ICMP protocol's mandatory ECHO_ REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams have an IP and ICMP header, followed by a destruct time value and an arbitrary number of pad bytes to fill out the packet. The default length of a datagram length is 64 bytes, but you can change the length with the ping command. Entering ping host name without any options will either report host is alive or no answer from host. Options to the ping command report additional statistics. See your UNIX system documentation for details. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ 34 Testing Command syntax /etc/ping [options] host [datasize[npackets]] ------------------------------------------------------------ Option Function ------------------------------------------------------------ -d Turn on the SO_DEBUG flag on the socket. -l Provide a long output that gives more statistical information. -r Bypass the normal routing tables and send directly to a host on an attached network.

This option lists other received ICMP packets beside ECHO_RESPONSE. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ 3 Troubleshooting ------------------------------------------------------------ This chapter describes how to troubleshoot the terminal by: · Using a flowchart. · Using error codes displayed by the terminal. · Checking a table of general problems. 3.1 Identifying the Terminal's Configuration You can identify the terminal's hardware configuration by checking the firmware revision level.

This section describes how to interpret the LED error codes. If the screen cannot display an error message, determine the LED error code and use Table 3-1 to troubleshoot the error. Table 3-5 LED Error Reporting Method ------------------------------------------------------------ Self-Tests System Logic Board LED Keyboard LEDs Screen Message ------------------------------------------------------------ Level 0 Repeating blinking pattern Not used Yes (if possible) Level 1 and menu-driven diagnostics Blinking pattern (one time) Blinking pattern (one time) Yes (if possible) ------------------------------------------------------------ Level 0 LED Errors Turn on the terminal. Level 0 testing begins. If a level 0 error occurs, the diagnostics try to display an error message on the screen and on the system logic board LED. Level 0 errors are not reported on the keyboard LEDs. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Troubleshooting 43 To interpret blinking LED error codes on the system logic board: The LED displays the two-digit decimal error code in the following pattern: First digit ! 2-second pause ! second digit ! 6-second pause Each digit is represented by the corresponding number of blinks: on for 0.5 seconds and off for 0.5 seconds. For example, if there is a ROM checksum error (error code 12), the system logic board LED: Blinks one time ! pauses for 2 seconds ! blinks two times ! pauses for 6 seconds ! repeats the sequence. See Table 3-1 for a list of error codes and recommended solutions. Level 1 LED Error Codes After level 0 testing is complete, the operating system starts and level 1 testing starts. When a level 1 error occurs, the screen displays an error message in the upper-left corner and testing continues. When level 1 testing is complete, the keyboard bell does not ring and diagnostics displays the error message in three places. · On the screen, in the diagnostic summary box · On the keyboard LEDs (one time, no repeat) · On the system logic board LED (one time, no repeat) To interpret blinking error codes on the keyboard LEDs: For each two-digit error code, the first digit blinks on the hold LED and the second digit blinks on the lock LED. The pattern of blinks is First digit ! 2-second pause ! second digit ! 6-second pause Each digit is represented by the corresponding number of blinks: on for 0.5 seconds and off for 0.5 seconds. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ 44 Troubleshooting For example, if there is an optional memory error (error code 13), the keyboard LEDs display the error message as follows: Hold LED blinks one time ! 2-second pause ! lock LED blinks three times. Keyboard LEDs do not repeat the error code sequence. See Table 3-1 for a list of error codes and recommended solutions. 3.4 Troubleshooting General Problems Table 3-6 describes some general operating problems with possible causes and suggested solutions.
