RVP8 User’s Manual April 2003 Software Installation A. Software: Basics, Installation and Backup A.1 Overview The RVP8 and RCP8 are implemented using standard PCI components with some custom cards supplied by SIGMET. While seemingly very different products, these actually have very similar hardware and software. The software installation, configuration and backup/recovery procedures are nearly identical. For this reason, this appendix is written to cover both the RVP8 and RCP8.
RVP8 User’s Manual April 2003 Software Installation A.2 Basics of Login, Logout and Shutdown The RVP8 and RCP8 both use the Linux operating system and X–Windows. When logging into the RVP8 either locally or over the network via “telnet” you will need to supply a user name and password. The system is tolerant of the AC power being suddenly turned-off, but in general it is recommended to follow a power-off shutdown procedure. These procedures are described in this section.
RVP8 User’s Manual April 2003 Software Installation Your system administrator can change either of these passwords by using standard Linux password support. A.2.4 Login procedure Local login as operator after power-up Connect keyboard, mouse and monitor and then cycle power on the system to force a reboot. This causes Linux to recognize these devices on power-up. At the power-up “login” prompt type “operator” and press Enter.
RVP8 User’s Manual April 2003 Software Installation A.2.5 Logout procedure Logout from X Windows Method 1: Right-click the mouse and select “Exit”. Method 2: Simultaneously click “Ctrl-Alt-Backspace”. You will be logged out and the screen will show the initial login prompt. on the full screen terminal. Root Logout from full screen terminal If you logged–in as root from the power-up full screen terminal, A.2.
RVP8 User’s Manual April 2003 Software Installation A.3 Software Installation A.3.1 When to perform software installation When your unit arrives, it is shipped with all software installed. Therefore, software installation is usually not necessary at the initial installation. There are two occasions when you might want to re-install the software: Installation of a new CDROM release from SIGMET. Recovery in the event of disk corruption or failure. A.3.
RVP8 User’s Manual April 2003 Software Installation A.3.3 Installing the system software After you have prepared for the installation, as described in the previous section, you are ready to install the software. Initial software installation steps Ready the unit with keyboard, mouse, monitor, etc. as described in the previous section. Switch the power on using the switch on the lower right front of the unit.
RVP8 User’s Manual April 2003 Software Installation Booting from the RDA Installation CDROM When the BOOT: prompt is presented, type the following command, depending on the version of CPU that is in your system: For Supermicro –G2 board type: linux ks=cdrom:/ks/ks–gb–hda.cfg For Supermicro –Q board type: linux ks=cdrom:/ks/ks–100.had.cfg4.8 After typing the appropriate command press ENTER. The software is installed automatically at this point.
RVP8 User’s Manual April 2003 Software Installation Installation steps to “flash” FPGA’s in SIGMET devices In this section you will be installing FPGA software into each of the SIGMET components. You will need to make an inventory of what is in your system and then issue an “rdaflash” command to each one as described below: Login as “operator” with password “xxxxxx” (6 x’s) You will enter X–Windows. Right click the mouse and start a terminal window.
RVP8 User’s Manual April 2003 Software Installation Reboot power-up check and RDA diagnostics After you have completed the installation steps above, you should reboot the unit. You can observe the progress of the reboot on the monitor. In addition, the front panel LED display will show the time of the reboot and display diagnostic messages. Typically about 1 minute is required for the system to complete reboot.
RVP8 User’s Manual April 2003 Software Installation A.4 System Software Configuration After the receiving your unit from the factory, or after software re–installation, there are several configuration steps required to customize your system for your particular environment and application. The configuration tools available for this are summarized in the table below.
RVP8 User’s Manual April 2003 Software Installation A.4.1 Configuring the softplane.conf file What is the softplane.conf file ? The softplane.conf file is used to define pin–by–pin assignment of I/O functions to various connectors on the I/O-62 connector panel. It is a plain text ASCII file that is self-documented. Since the RVP8 and RCP8 have virtually no jumpers, or wirewrap, all I/O configuration on the I/O-62 connector panel is done by software approach according to this file. Where is softplane.
RVP8 User’s Manual April 2003 Software Installation softplane.conf file example An example from the beginning and some excerpts from the softplane.conf file are shown below (note that the command “cat” causes the file to be listed on a terminal): $ # # # # # cat /usr/sigmet/config/softplane.

RVP8 User’s Manual April 2003 Software Installation softplane. conf organization and syntax The softplane.conf file is used to define every I/O pin on every connector, on the PCI cards themselves and on the connector panel. There are two primary definitions that are made for each pin: Physical interface- the electrical properties (RS422 output, analog input, TTL output, etc.). Logical interface- The internal variable name that is associated with each pin.

RVP8 User’s Manual April 2003 Software Installation Next, each piece of hardware is identified as being either in use or not in use. splConfig.Io62[0].InUse = 1 splConfig.Io62[0].InUse = 0 if in use if unused or not installed Currently, the I/O-62 is the only I/O device supported by the softplane. The method of connecting to the I/O-62 is specified next, for example: splConfig.Io62[0].
RVP8 User’s Manual April 2003 Software Installation A.5 System Backup and Recovery Because both the operating system and the RDA software are contained on the RDA CDROM, in the event of a serious failure, the complete software is simply re-installed from scratch. There are however, a few files that contain your custom configurations. In general these are files in the /usr/sigmet/config directory and the /etc directory. In fact, since they are all simple text files, they will, in most cases, fit onto a 1.
RVP8 User’s Manual April 2003 Software Installation Preparing the floppy backup media Every time you backup, you should use a freshly formatted floppy. It is possible to have several backups on a single floppy, but this is a bit risky if that diskette fails. Indeed some system managers even make two backups for added security. This is a smart thing to do. There are three ways to format a floppy: Purchase formatted floppies. This is the easy way. Format the floppy on a Windows machine.
RVP8 User’s Manual April 2003 Software Installation Mounting the floppy backup media Insert the floppy disk into the drive and then mount it (first use the su command to become root): $ su Password: # mount /dev/fd0 /mnt/floppy If there is a problem with this, check that there is a directory called /mnt/floppy.
RVP8 User’s Manual April 2003 Software Installation Running rda_backup After the media has been prepared and mounted (in the case of an FDD), then simply type the command: for floppy disk back- $ rda_backup –v /mnt/floppy up In the case of a hard disk backup to a directory such as /tmp/backup you would type: for hard disk backup $ rda_backup –v /tmp/backup The rda_backup utility will then check all of the directories where you have likely made configuration file changes.
RVP8 User’s Manual April 2003 Software Installation A.5.2 System Recovery Recovering an entire system In the event that your system becomes “un–bootable” perhaps because of a disk failure or corruption, you will simply re–install the entire system per Section A.3.3, and then use your rda_backup floppy disk and the rda_restore utility to recover your custom configuration files.
RVP8 User’s Manual April 2003 Software Installation Un-mounting and removing the floppy or CDROM In the case of a floppy, become root and then issue the “umount” command: $ su Password: # cd / # umount /dev/fd0 (Note: spelling is indeed “umount”) You may now push the button to eject the floppy. For a CDROM, you can use the eject command (instead of “umount”): # eject This completes the restoration of your custom configuration files. A.5.
RVP8 User’s Manual April 2003 Software Installation Copy to a floppy First check the size of the backup file to determine if it will fit on a floppy. To do this for backup files stored in /tmp/backup: $ cd /tmp/backup $ ls –als The file size in bytes is shown just to the left of the date column. To fit on a floppy the backup file that you want to copy it must be less than 1,440,000 bytes (1.44 MB). If it is larger than this you cannot use the floppy approach.
RVP8 User’s Manual April 2003 Software Installation A.6 Software Upgrade and Support A.6.1 Where to get software upgrades The RVP8 and RCP8 (collectively the RDA) are active products. New features and bug repairs are provided in the form of software upgrades. Software upgrades from SIGMET can be obtained from two sources: RDA Network Upgrades- These are available from ftp.sigmet.com. For example, to obtain the release RDA 8.00 you would go to: ftp.sigmet.com/outgoing/releases/rda–8.00 Section A.6.
RVP8 User’s Manual April 2003 Software Installation A.6.4 Getting the network upgrade files There are two ways to get the network upgrade files. Both techniques use ftp to get the files from ftp.sigmet.com. The ftp client service is enabled on the RVP8 allowing you to run an ftp session on the RVP8 and “get” files from another networked computer: Use the RVP8 to get the files- a one-step procedure that requires that you have internet access from the RVP8.
RVP8 User’s Manual April 2003 Software Installation ftp> dir You will see a directory listing of available releases. You are looking for an “rda” release. Assume it is rda–8.00, then: ftp> cd rda–8.00 ftp> dir Now you will see a list of files with file sizes. If you have a low-speed link, then you will want to download only a minimal installation which consists of: app.gz install install.gz install.
RVP8 User’s Manual April 2003 Software Installation Completing the two-step approach using another computer The two step approach is to use another computer to get the upgrade files and then get these files on the RVP8. The first step of getting the files from SIGMET is done analogus to the one-step approach described above. The second step is to ftp the files from the other computer to the RVP8. This is also analogous to the procedure described above.
RVP8 User’s Manual April 2003 Software Installation A.6.5 Starting the “install” utility The install utility is a graphical user interface that allows you to install SIGMET-supplied software either as a new installation or as an upgrade. In the case of the RDA, install is used to perform software upgrades only. New RDA installations use the procedure described in Section A.3.3 since this also conveniently installs the proper Linux operating system in one step.
RVP8 User’s Manual April 2003 Software Installation A.6.6 Using the install utility The install utility is shown below. The utility allows you to select the source for the files and the system on which you want to do the installation. You can also select which files you want to install. The menu fields are described in the following sections. rvp8 rvp8 Install from/to, Read from- select whether you are installing from a temporary directory or a CDROM.
RVP8 User’s Manual April 2003 Software Installation Keep old files- should be clicked-in, unless the release notes specify otherwise. When you have finished making your selections, then click Start to do the install. A text status screen will show you the progress of the install. If you had clicked Verbose, then this status screen would show more detail.
RVP8 User’s Manual April 2003 Software Installation A.7 Network Basics The RVP8 and RCP8 are generally delivered from SIGMET packaged as fully integrated Linux based computers running the SIGMET RDA application software. Being Linux computers, they have the ability to interface to a computer network- in fact, for normal operation in communicating with host software running on a different computer, they must be connected to a network.
RVP8 User’s Manual April 2003 Software Installation A.7.2 Making Changes to Default Configuration The one change that probably will be needed to the RVP8/RCP8 in almost every instance is to change the default IP address of ETH0. This will of course allow you to use the RVP8/RCP8 on a pre–existing computer network. IP Address Configuration To change the IP address, you must edit the file /etc/sysconfig/network_scripts/ifcfg–eth0.
RVP8 User’s Manual April 2003 Software Installation Hosts and DNS In the out of the box configuration, the RVP8/RCP8 can communicate with other computers on the network, but only by using IP Addresses. If you want to communicate with other computers using Hostnames, you must configure either a hosts table or DNS. Generally, a small network of only a few computers uses a hosts table, while large networks generally use DNS.
RVP8 User’s Manual April 2003 Software Installation course substitute the IP address of your NTP server for 192.168.76.98 in this example. There are many other lines in the /etc/ntp.conf file, but these are not used for normal configuration and must be left with a comment symbol “#” prefixing them. Generally, you should only have one line without a comment symbol, and that is the “server ...” line defined above. Next you should edit “or create” the file /etc/ntp/step–tickers.
RVP8 User’s Manual April 2003 Packaging B. RVP8/RCP8 Packaging A standard RVP8/RCP8 processor consists of three separate units: Main Chassis Section B.1 RVP8 and RCP8 Connector Panel Section B.2 RVP8 and RCP8 IFD (IF Digitizer) Section B.3 RVP8 Only Because of the similarity of the packaging for the RVP8 and RCP8, both units are described here. The main chassis and connector panel are located in a rack within 100m of the IFD.
RVP8 User’s Manual April 2003 Packaging B.1 Main Chassis General Description SIGMET’s standard main chassis is a 4U rackmount/table top enclosure (43.2 wide x 43.2 long x 17.8 cm high) or (17 wide x 17 long x 7.00 inch high) which fits a standard 19-inch EIA rack. The system comes standard with hot–swap redundant power supplies. The chassis may be equipped with either a mother board or a single-board computer depending on how the unit was purchased. The chassis is shown in the following figures.

RVP8 User’s Manual April 2003 Packaging B.1.1 Main Chassis Front Panel The front panel is shown in Figure B–1. The front panel matrix plasma display is typically connected internally by a ribbon cable to either an I/O-62 card or an RVP8/Rx card. The display is used to show status and power-up test results. Power–up features are described in detail in Section 2.3.5. The function keys beside the display are not currently used.
RVP8 User’s Manual April 2003 Packaging B.1.2 Main Chassis Back Panel Figure B–2 shows an example of the main chassis back panel for the case of a motherboard system. There are three main sections to the Main Chassis back panel: Power section- on the left (looking from the rear) with the power entry module, alarm reset and three redundant hot-swap power supplies. PC I/O section- in the lower center with connectors for keyboard, mouse, monitor, network, etc. This is for a mother board example.
RVP8 User’s Manual April 2003 Packaging B.1.3 Main Chassis Back Panel Power Section WARNING: The Main Chassis power supply modules are NOT auto ranging. These must be set by a switch on each module for either 115/230 VAC 60/50 Hz. Verify these per the procedure below, before applying power to the system. The Main Chassis back panel is equipped with a modular AC power entry device. There are three hot-swap redundant power supply modules in the system.
RVP8 User’s Manual April 2003 Packaging B.1.4 Main Chassis Back Panel PC I/O Section The PC I/O section shown above is where you make all of your standard PC connections. Note pins (male) are indicated by filled black circles while sockets (female) are indicated by open circles. A standard keyboard and mouse are provided with the unit. VGA monitor is supplied by the customer or ordered as an option from SIGMET. Note that LAN 1 and LAN 2 are standard RJ45 connectors.
RVP8 User’s Manual April 2003 Packaging B.1.5 Main Chassis Back Panel PCI Card Section The PCI cards are installed vertically on the right of the chassis (looking from the back). Since there are many different RVP8/RCP8 configuration options that can be ordered, there is quite a bit of variability in what PCI cards are installed. For the RCP8, however, there is typically only an I/O-62 PCI Card. Note that COM2 is typically installed as a connector in the PCI section.
RVP8 User’s Manual April 2003 Packaging B.2 I/O-62 and Connector Panel Figures B–5 and B–6 show the I/0-62 Connector Panel for the RVP8 and RCP8. This is typically mounted on the same rack as the Main Chassis. A 1:1 62–position cable (standard 1.8 m/6 foot) connects the connector panel to the I/O-62. As shown in the figures, the cable can be connected to either the front or the back of the panel so that the cable run can be optimized.
RVP8 User’s Manual April 2003 Packaging There are a few additional constraints that should be kept in mind when assigning electrical signals to a block of eight I/O–62 lines. These are: When TTL/CMOS pull-up/pull-down resistors are enabled, they are applied to the entire group of eight lines. This is somewhat inconsistent with using some of those same lines as RS–422. Similarly, when RS–422 terminators are enabled, they are applied to all four line pairs.
