Preinstalled Software

The Sun Cobalt LX50 server comes preinstalled with Sun Linux 5.0, as well as the following applications:

• MySQL server and client

• Apache

In addition, the following applications are

.tar

ﬁles or RPMs included under the

/opt/SunApps

directory that need

to be installed:

• Sun Grid Engine

• Sun Streaming Server

• Sun One Active Server Pages

• JDK 1.4

• Tomcat

• J2SE Development Kit

In addition to above applications, the server has a dedicated disk partition that contains diagnostic software to verify and troubleshoot server operation. The server also implements the Intelligent Platform Management Interface (IPMI) standard that runs autonomously from the Sun Linux operating system. IPMI performs fault management on the server, logging events and controlling status LEDs on the Main Board as well as the front and rear panels.

For further information on how to use the Sun Linux Installer and Rescue CDs to reinstall Sun Linux and conﬁgure the Sun Linux operating environment, see the manual titled Sun Linux 5.0 User Guide .

Installing the Server in a Rack

This chapter describes how to intall theSun Cobalt™ LX50 in a rack, using a four-post, two-post, or front-mount rack system. This chapter contains the following sections:

• “Decide Where to Conﬁgure the Sun Cobalt LX50 server” on page 2-1

• “Precautions” on page 2-2

• “Introduction” on page 2-3

• “Installing the Server Using the Bracket Kit” on page 2-4

• “Installing the Server Using the Slide Rail Kit (Optional)” on page 2-21

• “Connecting the Cables” on page 2-27

Decide Where to Conﬁgure the Sun Cobalt LX50 server

Before installing the Sun Cobalt™ LX50 server, it is best to decide where you want to conﬁgure it:

• In the rack

• On the bench

If you are going to conﬁgure the server after it is mounted in the rack, proceed to the section titled “Precautions” on page 2-2. To conﬁgure the Sun Cobalt LX50 server while it is in the rack, it is best to use a laptop to connect to the server Emergency Management Port (EMP) on the front panel of the server. See “Conﬁguring an External Serial Console” on page 4-7 for details on hooking up the laptop to the EMP.

If you are going to conﬁgure the server in a lab environment before it is installed in a rack, proceed to Chapter 3, “Powering On and Conﬁguring the Server,” then proceed to the section in this chapter titled “Precautions” on page 2-2.

Note: The preferred method is to conﬁgure the server on a lab bench, as all of the server

✍

components are much more accessible.

User Guide—Sun Cobalt LX50 Server 2-1

Chapter 2: Installing the Server in a Rack

Precautions

Before beginning the rack installation process, read through the following precautions.

Anchor the Equipment Rack

The equipment rack must be anchored to an unmovable support to prevent it from falling over when one or more servers are extended in front of it on slide assemblies. The equipment rack must be installed according to the manufacturer's instructions. You must also consider the weight of any other device installed in the rack.

Main AC Power Disconnect

You are responsible for installing an AC power disconnect for the entire rack unit. This main disconnect must be readily accessible, and it must be labeled as controlling power to the entire unit, not just to the server(s).

Grounding the Rack Installation

To avoid the potential for an electrical shock hazard, you must include a third wire safety grounding conductor with the rack installation. If server power cords are plugged into AC outlets that are part of the rack, you must provide proper grounding for the rack itself. If server power cords are plugged into wall AC outlets, the safety grounding conductor in each power cord provides proper grounding only for the server. You must provide additional, proper grounding for the rack and other devices installed in it.

Temperature

The ambient operating temperature of the server, when installed in an equipment rack, must not go below 5 ˚C (50 ˚F) or rise above 35 ˚C (95 ˚F). Extreme ﬂuctuations in temperature can cause a variety of problems in your server.

Ventilation

The equipment rack must provide sufﬁcient airﬂow to the front of the server to maintain proper cooling. It must also include ventilation sufﬁcient to exhaust a maximum of 850 BTUs per hour for a fully loaded Sun Cobalt LX50 server.

It is important to note that this is the maximum, and a minimum or typical system could be much less. You may want to calculate the BTU/hr more accurately for your conﬁguration. An extra 500 BTUs per hour over many systems would translate into a large error when calculating air-conditioning capacity.

2-2 User Guide—Sun Cobalt LX50 Server

Introduction

There are two methods for installing the Sun Cobalt LX50 server in a rack:

• Bracket Kit (see “Installing the Server Using the Bracket Kit” on page 2-4)

This mounting method is quick and easy, but makes it somewhat difﬁcult to service the server.

There are three mounting methods using the bracket kit:

• Four Post (see “Mounting in a Four-Post Rack System” on page 2-5)

• Mid Mount (see “Mid-Mounting in a Two-Post Rack System” on page 2-11)

• Front Mount (see “Front-Mount-Only in a Two-Post Rack System” on page 2-15)

Four-post mounting is the recommended method. It the most stable and sturdy method. The mid-mount system requires only two posts, but the posts must be adequately strong and stable to support the weight of multiple servers. The front mount method is highly discouraged, as most racks are unable to safely and reliably support the entire weight of a server through the front rack posts.

• Optional Slide Rail Kit (see “Installing the Server Using the Slide Rail Kit (Optional)” on page 2-21)

This mounting method is more complicated, but allows the server to be more easily serviced.

Note: At various points during installation, you must either remove or replace the front bezel.

✍

To remove the bezel:

1. Use the ﬁngerhole to pull the bezel out.

2. Pull out the right side ﬁrst, allowing the left side to rotate in the chassis handle until it comes loose.

To replace the bezel:

1. Snap the left side of the bezel into the left chassis handle.

2. Swing the right side of the bezel in, allowing the left side to rotate in the chassis handle.

3. Gently push the right side of the bezel into the right hand chassis handle until it snaps into place.

The bezel is held in place by the chassis handles. The instructions for removing and replacing the bezel are given here, to avoid repetition in subsequent sections. You will ﬁnd the bezel in the accessory compartment of the shipping materials.
