How to Replace a Network Interface Card With Dynamic Reconfiguration

• The HP 1-Port 1GbE Flex IO NIC provides Wake-on-LAN (WOL) support through the Flex IO port. A system that supports Wake on LAN can remain available to a systems administrator during its normal downtime. Once the machine is awakened, the systems.
• Watch the demonstration on replacing the NIC Card Slot 1 for the Dell EMC IDPA DP4400 Learn more: https://bit.ly/2TpMkSi.
• Slot 1 refers to the physical and electrical specification for the connector used by some of Intel 's microprocessors, including the Pentium Pro, Celeron, Pentium II and the Pentium III. Both single and dual processor configurations were implemented. Intel switched back to the traditional socket interface with Socket 370 in 1999.

The following procedure applies only to systems that support dynamic reconfiguration(DR). It specifically refers to configuration steps after DR is completed. You no longer need toreconfigure network links after you complete the DR process. Instead, you just transfer the linkconfigurations of the removed NIC to the replacement NIC.

In such a system, the slot number to be specified for the NIC driver is simple; it should be equal the PCI slot number. For instance, a NIC card in PCI slot 1 should use the SLOT=1 parameter for the NIC driver. However, many systems do not have such a simplistic arrangement.

The procedure does not describe the steps to perform DR itself. Consult your systemdocumentation for that information.

For an introduction to DR, see Chapter 2, Dynamically Configuring Devices in Managing Devices in Oracle Solaris 11.3.

Before You Begin

Make sure that you complete the following steps first:

• Ensure that your system supports DR.

• Consult the appropriate manual that describes DR on your system.

  To locate current documentation about DR on Sun servers from Oracle, search for 'dynamicreconfiguration' on https://docs.oracle.com/en/servers/.

  For information about performing DR in the Oracle Solaris Cluster environment, see Oracle Solaris Cluster 4.3 System Administration Guide.

1. Become an administrator.
2. (Optional)Display information about the physical attributes of datalinks and their respective locationson the system.

   For more information about the type of information that is displayed by the dladmshow-phys -L command, refer to the dladm(1M) man page.

3. Perform the DR process, as described in your system's documentation.
4. After you have installed the replacement NIC, proceed as follows, depending on thecircumstance that applies:
   • If you inserted the replacement NIC into the same slot as the old NIC, proceed to Step5.

     With the new NIC using the location that was previously occupied by the old NIC, the new NICinherits the link name and the configuration of the old NIC.

   • If you inserted the replacement NIC into a different slot, and the new NIC needs to inheritthe datalink configuration of the removed NIC, rename the link as follows:

     new-datalink

     Refers to the datalink of the replacement NIC that is in a different slot from the locationfrom which the old NIC was removed.

     old-datalink

     Refers to the datalink name that is associated with the old NIC that was removed.

     Note - In this scenario, the slot from which the old NIC was removed must remain empty.

     For example, the NIC in slot 1 is removed, and then the new NIC is inserted in slot 2. No NICis inserted in slot 1. Assume that the datalink on slot 1 is net0, and thedatalink on slot 2 is net1. You would specify that the datalink of the new NICinherit the datalink configuration of the old NIC as follows:

5. Complete the DR process by enabling the new NIC's resources so that they are available foruse.

   For example, you can use the cfgadm command to configure the NIC. Formore information see the cfgadm(1M) man page.

6. (Optional)Display link information.

   You can use either the dladm show-phys command or the dladmshow-link command to display information about the datalinks.

The following example shows how a bge card with link namenet0 is replaced by an e1000g card. The link configurations ofnet0 are transferred from bge to e1000gafter e1000g is connected to the system.

You would perform the DR-specific steps such as using the cfgadm command toremove the bge card and then install the e1000g card in itsplace. After the card is installed, the datalink of e1000g0 automatically assumesthe name net0 and inherits the link's configuration.

A network interface card (NIC) is a hardware component without which a computer cannot be connected over a network. It is a circuit board installed in a computer that provides a dedicated network connection to the computer. It is also called network interface controller, network adapter or LAN adapter.

Purpose

• NIC allows both wired and wireless communications.

• NIC allows communications between computers connected via local area network (LAN) as well as communications over large-scale network through Internet Protocol (IP).

• NIC is both a physical layer and a data link layer device, i.e. it provides the necessary hardware circuitry so that the physical layer processes and some data link layer processes can run on it.

Types of NIC Cards

NIC cards are of two types −

Internal Network Cards

Nic Slot 12

In internal networks cards, motherboard has a slot for the network card where it can be inserted. It requires network cables to provide network access. Internal network cards are of two types. The first type uses Peripheral Component Interconnect (PCI) connection, while the second type uses Industry Standard Architecture (ISA).

External Network Cards

Nic Slot 1000

In desktops and laptops that do not have an internal NIC, external NICs are used. External network cards are of two types: Wireless and USB based. Wireless network card needs to be inserted into the motherboard, however no network cable is required to connect to the network. They are useful while traveling or accessing a wireless signal.
