About Network InterfacesThe Sun Fire V890 server provides two on-board Ethernet interfaces--one Gigabit Ethernet and one Fast Ethernet interface. The 100BASE-TX Fast Ethernet interface is located on the system I/O board and conforms to the IEEE 802.3u Ethernet standard. The Fast Ethernet interface is an auto-sensing, switchable interface that can operate at 100 Mbps or 10 Mbps. It negotiates automatically with the remote end of the link (link partner) to select a common mode of operation. The 1000BASE-SX Gigabit Ethernet interface resides on the system motherboard and conforms to the IEEE 802.3z Ethernet standard. The Gigabit Ethernet interface operates at 1000 Mbps only. Two rear panel connectors provide access to the on-board Ethernet interfaces:
Additional Ethernet interfaces or connections to other network types are available by installing the appropriate PCI interface cards. A Gigabit Ethernet or Fast Ethernet PCI card can serve as a redundant network interface for one of the system's on-board interfaces. If the active network interface becomes unavailable, the system can automatically switch to the redundant interface to maintain availability. This capability is known as automatic failover and must be configured at the Solaris Operating System level. For additional details, see About Redundant Network Interfaces. The ge Gigabit Ethernet driver, the eri Fast Ethernet driver, and drivers for several other network interfaces are installed automatically during the Solaris installation procedure. For more information, see the Solaris documentation included with your software. For instructions on configuring the system's network interfaces, see:
About Redundant Network InterfacesYou can configure your system with redundant network interfaces to provide a highly available network connection. Such a configuration relies on special Solaris software features to detect a failed or failing network interface and automatically switch all network traffic over to the redundant interface. This capability is known as automatic failover. To set up redundant network interfaces, you can enable automatic failover between the two similar interfaces using the multipathing feature of the Solaris Operating System. For additional details, see About Multipathing Software. A qualified service technician can also install a pair of identical PCI network interface cards, or add a single card that provides an interface identical to one of the two on-board Ethernet interfaces. To help maximize system availability, make sure that any redundant network interfaces reside on separate PCI buses, supported by separate PCI bridges. For additional details, see About PCI Cards and Buses. How to Configure the Primary Network InterfaceBefore You BeginYou must perform the following tasks:
If you are using a PCI network interface card, see the documentation supplied with the card.
What to Do1. Choose a host name for the system. The host name must be unique within the network. It can consist only of alphanumeric characters and the dash (-). Do not use a dot in the host name. Do not begin the name with a number or a special character. The name must not be longer than 30 characters. 2. Determine the unique Internet Protocol (IP) address of the network interface and make a note of it. You need to furnish the address in a later step. An IP address must be assigned by your network administrator. Each network device or interface must have a unique IP address. 3. Resume the installation of the system. Return to How to Install the Sun Fire V890 Server.
What NextAfter completing this procedure, the primary network interface is ready for operation. However, in order for other network devices to communicate with the system, you must enter the system's IP address and host name into the namespace on the network name server. For information about setting up a network name service, consult:
The device driver for the system's on-board Sun GigaSwift Ethernet interfaces is automatically installed with the Solaris release. For information about operating characteristics and configuration parameters for this driver, refer to the following document:
This document is available at http://docs.sun.com, under Solaris on Sun Hardware. Refer also to the Sun Fire V890 Server Product Notes for late-breaking details. If you want to set up an additional network interface, you must configure it separately, after installing the operating system. See:
How to Configure Additional Network InterfacesBefore You BeginPerform the following tasks to prepare an additional network interface:
If you are using a PCI network interface card, see the documentation supplied with the card.
What to Do1. Choose a network host name for each new interface. The host name must be unique within the network. It can consist of alphanumeric characters and the dash (-). Do not use a dot in the host name. Do not begin the name with a number or a special character. Usually an interface host name is based on the machine host name. For example, if the machine is assigned the host name sunrise, the added network interface could be named sunrise-1. The machine's host name is assigned when Solaris software is installed. For more information, see the installation instructions accompanying the Solaris software. 2. Determine the IP address for each new interface. An IP address must be assigned by your network administrator. Each interface on a network must have a unique IP address. 3. Boot the operating system (if it is not already running) and log on to the system as superuser. Be sure to perform a reconfiguration boot if you just added a new PCI network interface card. See How to Initiate a Reconfiguration Boot. Type the su command at the system prompt, followed by the superuser password. 4. Create an appropriate /etc/hostname file for each new network interface. The name of the file you create should be of the form /etc/hostname.typenum, where type is the network interface type identifier (some common types are le, hme, eri, and ge) and num is the device instance number of the interface according to the order in which it was installed in the system. For example, the file names for the system's on-board Fast Ethernet and Gigabit Ethernet interfaces are /etc/hostname.eri0 and /etc/hostname.ge0, respectively. Both interfaces have a device instance number of 0 since each interface is the first one of its type installed in the system. If you add a PCI Gigabit Ethernet adapter card as a second ge interface, it's file name should be /etc/hostname.ge1. At least one of these files--the primary network interface--should exist already, having been created automatically during the Solaris installation process.
5. Edit the /etc/hostname file(s) created in Step 4 to add the host name(s) determined in Step 1. Following is an example of the /etc/hostname files required for a system called sunrise, which has two on-board Ethernet interfaces (ge0 and eri0) and a PCI Gigabit Ethernet adapter card (ge1). A network connected to the on-board eri0 interface will know the system as sunrise, while networks connected to the ge0 and ge1 interfaces will know the system as sunrise-1 and sunrise-2, respectively. sunrise # cat /etc/hostname.eri0 sunrise sunrise # cat /etc/hostname.ge0 sunrise-1 sunrise # cat /etc/hostname.ge1 sunrise-2 6. Create an entry in the /etc/hosts file for each active network interface. An entry consists of the IP address and the host name for each interface. The following example shows an /etc/hosts file with entries for the three network interfaces used as examples in this procedure. sunrise # cat /etc/hosts # # Internet host table # 127.0.0.1 localhost 129.144.10.57 sunrise loghost 129.144.14.26 sunrise-1 129.144.11.83 sunrise-2 7. Manually plumb and enable each new interface using the ifconfig command. For example, for the logical interface ge0, type: sunrise # ifconfig ge0 plumb up For more information, see the ifconfig(1M) man page. What NextAfter completing this procedure, any new network interfaces are ready for operation. However, in order for other network devices to communicate with the system through the new interface, the IP address and host name for each new interface must be entered into the namespace on the network name server. For information about setting up a network name service, consult
The eri and ge device drivers for the system's on-board Ethernet interfaces are automatically configured during Solaris installation. For information about operating characteristics and configuration parameters for these drivers, refer to the following documents:
These documents are available with your Solaris software and online at http://docs.sun.com, under Solaris on Sun Hardware. Refer also to the Sun Fire V890 Server Product Notes for late-breaking information.

How to Attach a Twisted-Pair Ethernet CableBefore You BeginComplete the prerequisite steps in:
What to Do1. Locate the RJ-45 twisted-pair Ethernet (TPE) connector for the appropriate Fast Ethernet interface. See Locating Rear Panel Features. For a PCI Fast Ethernet adapter card, see the documentation supplied with the card. 2. Plug in a Category-5 unshielded twisted-pair (UTP) cable to the appropriate RJ-45 connector. You should hear the connector tab click into place. The UTP cable length must not exceed 100 meters (328 feet). 3. Connect the other end of the cable to the RJ-45 outlet to the appropriate network device. You should hear the connector tab click into place. Consult your network administrator if you need more information about how to connect to your network. What NextIf you are installing your system, complete the installation procedure. Return to:
If you are adding an additional network interface to the system, then you need to configure that interface. See:
How to Select the Boot DeviceThe boot device is specified by the setting of an OpenBoot firmware configuration variable called boot-device. The default setting of this variable is disk net. Because of this setting, the firmware first attempts to boot from the system hard drive, and if that fails, from the on-board Fast Ethernet interface. Before You BeginBefore you can select a boot device, you must complete the installation procedure. See:
Specifically, you must set up a system console and power on the system. See:
If you want to boot from a network, you must also connect the network interface to the network and configure the network interfaces. See:
This procedure assumes that you are familiar with the OpenBoot firmware and that you know how to enter the OpenBoot environment. For more information about the OpenBoot firmware, see the OpenBoot 4.x Command Reference Manual, which is available at http://docs.sun.com, under Solaris on Sun Hardware. Refer also to the Sun Fire V890 Server Product Notes for late-breaking details. What to Do1. At the ok prompt, type: ok setenv boot-device device-specifier where the device-specifier is one of the following:
If you want to specify a network interface other than an on-board Ethernet interface as the default boot device, you can determine the full path name of each interface by typing: Theshow-devs command lists the system devices and displays the full path name of each PCI device. An example of a path name for a Fast Ethernet PCI card is shown below: /pci@8,700000/pci@2/SUNW,hme@0,1 2. To cause variable changes to take effect, type:
