Sun Enterprise 250 Server Owner's Guide

How to Boot the System Using the Standard Ethernet Interface

Before You Begin

Before you can boot the system over a network interface, you must complete the installation procedure; see:

"How to Install the Enterprise 250 Server"

Specifically, you must perform the following tasks:

Set up a system console; see "About Setting Up a Console"

Configure the Ethernet port; see "How to Configure the Standard Ethernet Interface"

Attach the Ethernet port to a network; see "How to Attach a Twisted-Pair Ethernet (TPE) Cable" or "How to Attach an MII Ethernet Transceiver"

Power on the system; see "How to Power On the System"

Note -

To boot the system over an Ethernet network, it is necessary that there be a bootable image for Sun4u architecture somewhere on the network. For details, see the installation instructions accompanying your Solaris software.

What to Do

At the ok prompt, enter either of the following commands:
1. To load the operating system into the server's volatile memory, enter:
```
ok boot net 
```
  Note -
  Because the operating system is only in volatile memory, it is not retained across power cycles.
2. To install the operating system onto the server's internal system disk, enter:
```
ok boot net - install
```
  Both commands boot the system, and the system console displays the system prompt.

What Next

If you want to use the main logic board Ethernet interface as the default boot device, you must change the value of certain OpenBoot parameters. For more information, see OpenBoot 3.x Command Reference Manual in the Solaris System Administrator AnswerBook for your specific Solaris release.
