This section describes the process of installing and configuring either Gigabit or Fast Ethernet products. The process is the same for both, except for configuring Jumbo Frames size. Jumbo Frames is a feature which is only available for Gigabit Ethernet cards. The process for configuring Jumbo Frames size is shown as an optional step in the installation process.

The Base-T cards operate at 10 or 100 Mbit/s in either full- or half-duplex modes and at 1000 Mbit/s only in full-duplex mode. The 1000Base-SX cards operate only at 1000 Mbit/s and in full-duplex mode. Ensure that your switch and La card are set according to the “Supported Configurations” table in chapter 1.

The following instructions are also available as a small, Installation Guide.

Release Notes for Ethernet products are available on http://docs.hp.com.

NOTE: Steps 1 and 2 may be skipped if your card is built-in or factory installed.

Step 1:

Access the system card bay

  1. If the system is running, shut it down with: shutdown -h. Answer y at the shut down prompt to continue.

  2. Wait for the system to shut down completely, and then power off the system by pressing the system off button. Ensure that the system is grounded.

  3. Open the system to gain access to the PCI-X backplane.

  4. Select an empty PCI-X slot and remove the slot cover.

Step 2:

Install the card

  1. Observe the antistatic precautions.

  2. Record the serial number located on the card for future reference.

  3. Grasp the card by its edges or faceplate with both hands, insert the card into the slot, and firmly but gently press the card in until it is fully seated.

  4. Secure the card and reassemble the system.

Step 3:

Connect the card to the network

  1. Attach the network cable to the card. For the 1000Base-SX card, cabling can be either 62.5 micron or 50 micron multimode fiber optic cable. For the 1000Base-T card, cabling must be 4-pair Cat5 or Cat-5E UTP copper wiring. See Appendix B “Cabling Requirements” for operating distances.

  2. Attach the free end of the cable to any unused port on the switch. Connect the power cable to system. Ensure that the 1000 Mbit/s port on the switch is set for autonegotiation.

    If using Jumbo Ethernet frames, ensure that all end stations on a given LAN (that is, no routers or layer 3 switches are in between) have the same MTU setting. However switch ports in the LAN can have any MTU setting greater than or equal to the end station MTU.

  3. Power up the system.

Step 4:

Prepare to install the software

  1. Log in as root.

  2. Check that the /usr/bin, /usr/sbin and /sbin directories are in your PATH by using the echo $PATH command.

  3. Check the HP-UX version by entering: uname -r

    # uname -r
    B.11.xx

  4. Install the appropriate patches for your system as described in the “Required Software” section of the Release Notes, which is available on the Web at http://docs.hp.com under Networking and Communications.

Step 5:

Install the software if you are:

  • adding a networking or I/O card to a system and

  • that networking or I/O card is newer than your system’s Operating Environment.

  1. Load the software media into the appropriate drive.

  2. Run the swinstall program to install the software.

  3. Change the host name after Source Host Name, if necessary.

  4. Click the Source Depot Path to identify the registered depot for the appropriate source depot path and activate the OK button to return to the Software Selection Window.

  5. Highlight the 1000Base-SX/T software as follows:

    • GigEther-00 (for cards such as A4926A and A4929A) on HP-UX 11i v1, or

    • GigEther-01 (for cards such as A6825A and A6847A) on HP-UX 11i v1. Check the Release Notes or ask your HP representative for a list of the latest cards supported.

    • IEther-00 (for cards such as A47011A and A7012A) on HP-UX 11i v1.

  6. Choose Mark for Install from the Actions menu to choose the product to be installed.

  7. Choose Install from the Actions menu to begin product installation and open the Install Analysis Window.

  8. Activate the OK button in the Install Analysis Window when the Status field displays a Ready message.

  9. Activate the YES button at the Confirmation Window to confirm that you want to install the software. swinstall loads the fileset, runs the control scripts for the filesets, and builds the kernel. This should take about 3 to 5 minutes. When the status field indicates Ready, click Done. A Note Window then opens. Click the OK button to reboot the system.

Step 6:

Configure the card using SAM

The following configuration is primarily for network cards that have been added into a system:

  1. Log in as root and verify that the card and its hardware path are displayed by entering: ioscan.

  2. Run the System Administration Manager by entering sam.

  3. Double-click Networking and Communications.

  4. Double-click Network Interface Cards.

  5. Highlight the Gigabit Ethernet card and choose Configure from the Actions menu.

  6. Fill in the form according to the instructions using the “Network card Configuration Worksheet” located in Appendix C.

  7. Click the OK button to activate the card and then select exit from the File menu until you exit SAM.

Step 7:

Verify the installation

  1. Verify that the connector’s Link LED is steadily on (this means the card and driver are installed successfully).

    NOTE: On cards that have them, speed LEDs indicate not only speed but also that there is a LAN connection. The link indication will occur before data activity indication. If the card and driver have been installed, but there is no LAN connection, all speed LEDs will be off.

  2. Obtain the PPA number and the station address of each card by using the lanscan command.

  3. To verify link-level connectivity with a remote system, enter:

    $ linkloop -i PPA_number remote_station_address

  4. To verify IP-level connectivity with a remote system, enter:

    $ ping Remote_IP_Address

  5. Installation is complete when you have successfully run linkloop, ping and netstat. To configure remote systems, see “Configuring Remote Network Connectivity Using SAM”. Do this step only if remote systems have not been previously configured.

Optional Step:

Configure Jumbo Frames Size (Gigabit Ethernet only)

  1. Jumbo frames for the gelan and igelan drivers on Hp-UX 11i v1 have an MTU setting of 9000. For the iether driver on HP-UX 11i v1, the jumbo frames setting is in the range of 1501-9000 bytes. For all allowable MTU values, refer to the table of “Allowable MTU Sizes” depending on which Gigabit Ethernet driver and which HP-UX version you are using.

    If you are using Jumbo Ethernet frames, ensure that all end stations on a given LAN* have the same maximum transmission unit (MTU) setting. However, switch ports in your LAN can have any MTU setting greater than or equal to the end station’s MTU. (*Note: here “LAN” means that the end stations do not have any routers or layer 3 switches in between them.)

  2. Obtain the PPA number of the card by entering lanscan.

  3. Choose one of two configuration methods that will permanently save your configuration.

    • use the GUI-based system admin manager (SAM).
      To use SAM, type sam at the HP-UX system prompt; then double-click Networking and Communications. Verify the MTU size by performing the next step (step 4); or

      edit the gigabit ethernet driver configuration file using an editor such as “vi.” Depending on which driver your La card uses, it can be any one of the following Gigabit Ethernet configuration files:

      • /etc/rc.config.d/hpietherconf

      • /etc/rc.config.d/hpigelanconf

      • /etc/rc.config.d/hpgelanconf


      Depending on which driver your La card uses, set the mtusize by editing HP_IETHER_MTU[0]=mtusize, HP_IGELAN_MTU[0]=mtusize, or HP_GELAN_MTU[0]=mtusize

      Depending on which driver your La card uses, insert the proper interface name: HP_IETHER_INTERFACE_NAME, HP_IGELAN_INTERFACE_NAME, or HP_GELAN_INTERFACE_NAME. When the system reboots, the interface will be configured for jumbo frame operation.

  4. Verify MTU change by entering netstat -rn. If MTU has not changed, enter the following commands:

    $ifconfig lanPPA_number unplumb
    $ifconfig lanPPA_number ip_address netmask netmask up

  5. To check (or verify) the current Ethernet frame size, enter:

    $lanadmin -m PPA_number

An alternative way to temporarily** configure jumbo frame size is to enter:
lanadmin -M mtu_size PPA_number.

The PPA_number is the one we obtained from the output of lanscan. For the iether Gigabit Ethernet driver, for example, the MTU value must be a value between 1501 and 9000 (for Jumbo Frames).

**Note: using lanadmin will not preserve your settings across reboots.
