3. FUNCTIONAL DESCRIPTION 3.2.3 MIRROR port The TTE-Switch A664 Lab v2.0 has a 10/100/1000 Mbit/s mirror port that can be used to forward selected traffic to a dedicated monitoring end system (e.g. a PC running Wireshark). For monitoring, an end system must be configured in the network description, or the mirror port must be configured via the RS-232 interface. Configuring the mirror port via the RS-232 interface is only possible in SHOP mode.
PAGE 16
3. FUNCTIONAL DESCRIPTION 3.2.6 RS-232 interface The RS-232 interface is used for debugging in SHOP mode (see Section 5.6 on page 22). The control interface complies with the RS-232 standard and enables connection to one of the COM ports of a PC using a serial 1:1 adapter cable (DB-9 connector to DB-9 socket). The settings are 19200 baud, 8 data bits, one stop bit, no handshake, no parity. Pin No.

5. STATE MACHINE ≡ 5 State machine Figure 9 on the current page shows the different states of the TTE-Switch A664 Lab v2.0 and the conditions for transitions between these states. Figure 9: The TTE-Switch A664 Lab v2.0 state machine The states of the TTE-Switch A664 Lab v2.0 correspond to the following ARINC 664P7-1 [2] specifications: TTE-Switch A664 Lab v2.
PAGE 22
5. STATE MACHINE NOTE Enabling Grnd-Mode via the DB-25P configuration plug puts the TTE-Switch A664 Lab v2.0 into unrestricted mode. Disabling Grnd-Mode puts the switch into restricted mode, by contrast. Restricted mode disallows maintenance operations that might pose a safety hazard during non-ground operation (i.e., flight mode) for a behavior similar to a flight switch. 5.1 INIT In the INIT state, the TTE-Switch A664 Lab v2.
PAGE 23
5. STATE MACHINE 5.3 OPERATIONAL After a successful initialization and configuration, the switch enters the OPERATIONAL state. In the OPERATIONAL state, the TTE-Switch A664 Lab v2.
PAGE 24
5. STATE MACHINE state makes it possible to access the system through the SHOP CLI from a serial terminal. Transitions Depending on the DB-25P configuration plug settings and whether errors are detected or not, the following transition from the SHOP state is possible: Transition to Shop-Mode Grnd-Mode Maintenance Error – – – Catastrophic Failure Ð→ QUIET 5.7 Error handling The TTE-Switch A664 Lab v2.

6. CREATING A SWITCH CONFIGURATION ≡ 6 Creating a switch configuration 6.1 Using TTE-Tools for configuration creation The configuration for the switch and the internal end system is created by the TTE-Tools (minimum recommended version: 5.4.4000) – TTE-Plan, TTE-Build Network Configuration, and TTE-Build Device Configuration. • TTE-Plan is the TTEthernet network design tool.
PAGE 26
6. CREATING A SWITCH CONFIGURATION 6.3 Configuring the internal end system The management CPU of the switch uses an internal end system to send and receive frames for data loading via ARINC 615A, ICMP (ping) and diagnostics via SNMP. NOTE Data loading, ICMP and SNMP via best-effort (Ethernet) traffic are always possible by selecting the default configuration via pin programming.
PAGE 27
6. CREATING A SWITCH CONFIGURATION the binary files defined in the second section correspond to position 2, and so forth. A section name, which is the name of a configuration, is given between square brackets and can be any string of a maximum of 16 ASCII characters. It is also possible to use blank spaces. The section name is packed into the configuration as well, which can be helpful during debugging. The following example shows a valid section in the example_configs.
PAGE 28
6. CREATING A SWITCH CONFIGURATION 6.5 Uploading the switch configuration The binary configuration file CONFIGS_BAK can be uploaded via A615 data loading or the RS-232 serial interface: 6.5.1 Upload via RS-232 serial interface To upload the configuration via RS-232 serial interface, connect to the switch via Tera Term or any other serial terminal application that is capable of transmitting raw bytes. 1. In the terminal window, enter file integrity to retrieve the states and names of the internal files. 2.

6. CREATING A SWITCH CONFIGURATION Successfully wrote file # Successfully updated active page 6.5.2 Upload via A615 data loading This section describes how to use the TTTech Data Loader to upload the configuration file to the TTESwitch A664 Lab v2.0. If you intend to use a different A615-compliant data loader, please see the user documentation for that product. NOTE The TT-615A3-Loader does not calculate a CRC for uploaded files. Therefore it is not fully compliant to ARINC 615A.

6. CREATING A SWITCH CONFIGURATION Operation Command and Description Find tt_615a3_console_w.exe -c cfg.loading_configuration -f Check if all clients specified in the configuration file exist in the network. Information tt_615a3_console_w.exe -c cfg.loading_configuration -i Retrieve additional information on each client specified in the configuration file. Upload tt_615a3_console_w.exe -c upload.loading_configuration -u Upload the files specified in the upload.

7. DIAGNOSIS ≡ 7 Diagnosis 7.1 Management Information Database The Management Information Database (MIB) describes the managed objects that can be retrieved via SNMP Version 1 on UDP port 161. Make sure to use the correct IP address according to your loaded configuration. NOTE In your preferred SNMP client, make sure to choose SNMPv1 and disable all the other versions of the SNMP protocol. The MIB files listed below can be loaded into any SNMPv1-compliant SNMP client.
PAGE 32
7. DIAGNOSIS • The number of faulty occurrences • The timestamp of the first faulty occurrence • The timestamp of the last faulty occurrence • The last faulty result value NOTE As long as a certain BIST has never failed, only the index and the latest value measured are reported via SNMP. For a complete list of implemented BISTs, see Appendix A. 7.3 Health message The TTE-Switch A664 Lab v2.0 sends a health message with a period of 1000 ms in the Best Effort Task-1.
PAGE 33
7. DIAGNOSIS 7.5 Serial command line interface A serial command line interface (CLI) that is passive, which means it only shows text messages, is available in the INIT, OPERATIONAL, and MAINTENANCE states. The SHOP mode starts an active CLI, which means that commands can be entered. This section describes the CLI that is available in the SHOP mode. • SHOP mode can be activated only if Grnd-Mode is set to ON on the DB-25P configuration plug.
PAGE 34
7. DIAGNOSIS The parameter can be one of the following names: CONFIGS_BAK Backup configuration image in the dataload area CONFIGS_DEF Default configuration image in the dataload area FIRMWARE_BAK Backup firmware image in the dataload area FIRMWARE_DEF Default firmware image in the dataload area NOTE It is not recommended to upload larger files due to the slow transfer speed of the serial interface (2 kb/s).
PAGE 36
8. TROUBLESHOOTING ≡ 8 Troubleshooting If you encounter a malfunction of the TTE-Switch A664 Lab v2.0, there are some basic checks you can perform: • Is the power supply voltage correct? • Is the pin programming correct for the desired configuration? • What do the status LEDs display? See Table 1 on page 11 for details. • Are all temperatures within the allowed ranges? See Section 7.2 on page 30 for details, and check the SNMP client output for the temperature values of the different sensors. 8.
