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.

Front-Mount-Only in a Two-Post Rack System

Warning: Your chassis rack-mount kit provides the option for mounting the system in a two-post front-mount-only conﬁguration. However, mounting your chassis using this option is not recommended for use in most rack systems. In fact, 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

If a front-mount-only conﬁguration is desired, it is highly recommended that you verify through your rack vendor that your speciﬁc rack is designed to support the excessive weight and stresses this type of mounting conﬁguration imposes on the rack. Structural failure of the rack is likely if it is not designed for this type of load. A four-post or a two-post mid-mount conﬁguration should be used when possible.

Connecting the Cables

The Sun Cobalt LX50 server has a number of connectors. Some are on the front panel; others are located on the rear panel. This section summarizes the usage of each connector.

Front Panel Connectors

To access the front panel connectors when a front bezel is installed, grasp the bezel on the right side at the ﬁnger hole and gently pull it towards you, unhinging it at the left until it unsnaps from the chassis. Figure 28 shows the front of the server with the bezel removed.

Figure 28. Front Panel (bezel removed)

RJ-45 Serial 2

USB1 USB2

There are three connectors on the right side of the front panel:

• Front RJ-45 Serial 2 connector (top connector, ttyS1)

• USB 1 connector (middle connector)

• USB 2 connector (bottom connector)

The BIOS is set by default to redirect BIOS, bootup, and Linux Loader (LILO) messages to the serial port. The default communications settings for the serial console ports on the server are:

• 9600 bps

• 8 data bits

• 1 stop bit

• No parity

• No ﬂow control

Front RJ-45 Serial 2 Connector

The Sun Cobalt LX50 server provides two common external RJ-45 serial ports, one located on the back of the system and the other located on the front panel.

The use of RJ-45 connectors for the serial interface is widely becoming a standard for use in the high-density server market. The intended usage model for the RJ-45 serial connector on the back of the system is for use as an interface to a serial port concentrator allowing for remote access to the server’s Emergency Management Port (EMP). The serial connector on the front panel (ttyS1) can be used as a direct connect to the EMP, allowing for PC-to-PC serial communications to perform diagnostics on a server mounted in a rack environment.

Table 7. RJ-45 Connector Usage

Mode Front Back

Modem No Yes

Serial Concentrator No Yes

PC-to-PC communication Yes Yes

Both front and back serial connectors cannot be used at the same time. Logic on the server Main Board determines which connector is in use.

If the front serial port is in use, the rear panel serial port is automatically disabled. When the front-panel serial port connection is removed, the system automatically re-enables the rear panel serial port.

The front RJ-45 usage model is intended for PC-to-PC serial communication only. It shares common serial signals with the RJ-45 serial port, located on the back of the system. However, it does not support a modem, as there is no RI signal. Instead it sets pin 5 to ground, causing logic on the Main Board to disable the rear serial port when a cable or adapter is plugged into it.

For a direct connect or PC-to-PC serial communication, either an 8-pin RJ-45-to-DB9 adapter or a cable supporting both DB-9 and RJ-45 connectors is necessary. Table 8 provides a pinout for the front RJ-45-to-DB9 adapter cable.

AC Power Connector

This connector is where you plug in the AC power cord (a power cord is supplied appropriate to your geographic region).

Warning: Do not attempt to modify or use the supplied AC power cord if it is not the exact type required.

The power supply cord is the main disconnect to AC power. The socket outlet must be installed near the equipment and readily accessible.

Rear Panel RJ-45 Serial 2 Connector

The intended use for the RJ-45 serial port, located in the back of the system, is for remote EMP communication by connecting the port to a serial terminal concentrator. With the optional RJ-45 to DB9 Serial Adapter Kit, the serial port can also be conﬁgured for use with a modem. Table 4, “Replaceable Components,” on page 1-4 gives ordering information for the adapter kit. The rear serial port is traditionally referred to as COM2 (DOS, Windows), or ttyS1 (Linux).

Serial terminal concentrators use one of two serial communication standards. Some terminal concentrators require a Data Carrier Detect (DCD) signal, while others require a Data Set Ready (DSR) signal. The server Main Board can be conﬁgured to support either of these conﬁgurations by setting the appropriate jumper on the jumper block, located directly behind the RJ-45 serial connector on the Main Board.

The back RJ-45 Serial 2 port can support any standard serial device. An RJ-45 connector was selected to allow for direct support for serial port concentrators, which typically use RJ-45 connectors and are widely used in the highdensity server market to access the server management features of the server.

To give support for either of two serial conﬁguration standards used by serial port concentrators, the J6A2 jumper block, located on the Main Board inside the server directly behind the rear RJ-45 serial port, must be jumpered appropriately according to which standard is desired.

Note: By default, as conﬁgured in the factory, the server Main Board has the back RJ-45 serial

✍

For serial devices that require a DSR signal (default), the J6A2 jumper block must be conﬁgured as follows: both jumpers are in position 1 and 2. Pin 1 is denoted by an arrow directly next to the jumper block.

a. The RJ-45-to-DB9 adapter used should match both the signal requirements of the serial device and the external RJ-45 serial port. The external RJ-45 serial port provides all standard serial port signals, however having only 8 pins, Pin 7 can be manually conﬁgured to support either a DCD or DSR signal by setting the J6A2 jumper block appropriately.

On the Sun Cobalt LX50 server, the adapters used for the back connector cannot be used with the front connector, as the pinout for the RJ-45 ports are different.

As an example, when using an external modem to access the server management features of the server Main Board, you must ﬁrst set the J6A2 jumper to support a DCD signal and make or choose the appropriate RJ-45-to-DB9 adapter.

• POST LEDs (multi-color). To help diagnose power-on self test (POST) failures, a set of four bi-color diagnostic LEDs is located on the back edge of the server Main Board. These LEDs are visible through holes in the rear panel. Each of the four LEDs can have one of four states: Off, Green, Red, or Amber. For detailed information on these LEDs, see “POST LED Indicators” on page 6-12.

• System ID LED (blue). This LED is located on the Main Board and is visible through holes in the rear panel. It can provide a mechanism for identifying one system out of a group of identical systems. This can be particularly useful if the server is used in a rack-mount chassis in a high-density, multiple-system application. The LED is activated by depressing the front panel System ID pushbutton or if the server receives a remote System Identify command from a remote management console. If activated by the front panel pushbutton, the LED remains on until the pushbutton is depressed again. When the LED illuminates due to a remote System Identify command, the LED turns off after a timeout period. An additional blue System ID LED is located on the front panel that mirrors the operation of the rear Main Board LED.

• Power Supply LED (green/amber). This is a bi-color LED that can be on, off, green, amber, or blinking, or combination thereof. See “Rear Panel Power Supply Status LED” on page 6-4 for more detailed information.

Powering On and Conﬁguring the Server

This chapter explains how to use the Power On switch to apply power to the server, boot to the Sun Linux 5.0 operating system, use the serial console, update system software, and validate the operation of the Sun Cobalt™ LX50 server. The chapter contains these sections:

• “Setting the Jumper Positions” on page 4-1

• “Powering On” on page 4-1

• “Clearing CMOS” on page 4-2

• “Booting Up” on page 4-2

• “Linux Loader (LILO) Menu Options” on page 4-6

• “Conﬁguring an External Serial Console” on page 4-7

• “Using the Service Partition Menu” on page 4-9

• “Restarting and Shutting Down” on page 4-26

Setting the Jumper Positions

Two jumpers on the Main Board are preset by default to the positions that satisfy most serial port conﬁgurations. They are located at the rear of the server, on the Main Board, next to the rear RJ-45 serial 2 connector. The two jumpers are on the jumper block labeled J6A2. The top cover of the server must be removed to access these jumpers. If you need to change these jumpers from their factory default positions, see “Rear Panel RJ-45 Serial 2 Connector” on page 2-30.

Powering On

Caution: The power switch on the front of the server is an On/Off switch, but it does not

isolate the equipment from the AC power being supplied through the AC power cord.

The location of the switch is shown in Figure 35.

Figure 35. Power and Reset Switches on the Front Panel

Front Panel Power On/Off Switch Reset Switch

User Guide—Sun Cobalt LX50 Server 4-1

Chapter 4: Powering On and Configuring the Server

Pushing the switch sends a signal to monitoring circuitry inside the server. The switch does not directly control high-voltage AC; it controls only low-voltage signals. When the monitoring circuitry detects that the button has been depressed, it activates the power supply and powers up the server. Likewise, when the server is powered up, pushing the switch powers the server down.

The main method for isolating the server from all high voltage is to physically remove the AC power cord. If the power cord is not removed, the only other way to isolate the server from high voltage is to open all external circuit breakers that supply AC voltage to the equipment.

Caution: As shipped, the Sun Cobalt LX50 server does not have Advanced Conﬁguration and

Power (ACPI) enabled in the Sun Linux™ 5.0 kernel and, as a result, the front panel power

switch operates as a normal power switch. In this conﬁguration, press the switch once and power comes on, press again and the power goes off. It is recommended that you use the standard Sun Linux 5.0 shutdown command before you power down the system using the switch. Activate the front panel switch to remove power only when Linux has completed the shutdown process and has halted.

Should you elect to use an ACPI-enabled Linux kernel and run the ACPI daemon (acpid), the behavior of the front panel switch will change to support the standard “soft-off” capability. That is, when the server is on and the power switch is pressed, the OS is notiﬁed and begins a graceful shutdown. Additionally, with ACPI enabled and the server on, pressing the power button for longer than four seconds forces an immediate (non-graceful) shutdown.

Clearing CMOS

It may be necessary to clear CMOS memory in order to restore the default BIOS passwords required to boot the server (user) or access setup functions (supervisor), as well as the default BIOS settings. To clear CMOS, follow these steps:

1. Power down the server

2. Push and hold the reset button for at least four seconds

3. While continuing to depress the reset button, push the server power button to power up the server

4. After power has been applied, release the reset button

Booting Up

As soon as power is applied to the server, the bootup process begins. Boot messages are sent to either a monitor attached to the video port, or to a serial console attached to the front or rear RJ-45 serial console ports.

The server is conﬁgured by default to initially send BIOS and kernel messages to both the serial console and the video port. However, when the boot process reaches the Linux Loader (LILO) point, the messages and screens are sent only to the video port. After bootup is ﬁnished, the conﬁguration can be changed to send all messages to the serial console (see “Conﬁguring an External Serial Console” on page 4-7).

Boot Options

The ﬁrst bootup screen is shown in Figure 36.

4-2 User Guide—Sun Cobalt LX50 Server

Booting Up

Service Partition <F4>

Press F4 to boot to the service partition. This partition allows you to set conﬁguration parameters and run diagnostics. See “Using the Service Partition Menu” on page 4-9 for more details.

When you are ﬁnished using the service partition, you must depress the Ctrl-Alt-Delete keys simultaneously to reboot.

Network <F12>

Press F12 to boot from the network. The server software then looks for a valid boot ﬁle name on the network. If it ﬁnds such a ﬁle name, it boots from the network. If it cannot ﬁnd a valid ﬁle name, it gives up and continues to boot from the hard disk. Figure 40 is an example of how the screen appears when booting from the network fails.

Figure 40. Network Boot Failed Screen

PXE (Pre-boot Execution Environment) is a method by which the server can booted from a remote server. This allows the system to boot without any knowledge of the Operating System on the server. The PXE environment uses DHCP to obtain network addresses. PXE is primarily used for loading operating systems, conﬁguring the system, or burn-in type testing. PXE booting will only work if a properly conﬁgured PXE server is available.

Choose Boot Device <ESC>

Press the Esc key to go to the boot device selection menu. This menu, shown in Figure 41, allows you to select the device from which the system will boot. To select a boot device, scroll to the desired device and press Enter; otherwise, press Esc to exit without changing the boot device.

Linux Loader (LILO) Menu Options

The bootup process eventually takes you to the Sun Linux loader screen. The Sun Cobalt LX50 server uses the standard LILO boot loader. You initially have four options:

• linux

• linux-serial

• linux-up

• linux-up-serial

In all cases, the serial ports on the front and rear panels are operational but their modes change. When you choose any of the serial boot options (linux-serial or linux-up serial), the serial port (ttyS1) becomes the default console device. The standard keyboard/mouse/VGA port becomes just a standard tty device. Conversely, when you choose any of the non-serial options (linux or linux-up), the standard Linux console is the keyboard/mouse/VGA port and the serial port becomes a standard Linux login terminal.

If you do nothing, the default option (linux) is automatically selected after about ﬁve seconds. This option is also selected if you press Enter before the ﬁve seconds is up. You may also manually select one of the options. To do this, press the Tab key. Pressing Tab brings up the following prompt:

Configuring an External Serial Console

Conﬁguring an External Serial Console

There are two RJ-45 serial console ports on the Sun Cobalt LX50 server, one on the front panel and one on the rear panel, as shown in Figure 42. You can direct boot messages to a serial console (for example, a laptop running HyperTerminal).

Figure 42. Front- and Rear-Panel Serial Console Ports

Front Panel Serial Console Port

OM11670A

Serial Console Port (ttyS1)

The default communications settings for the serial console ports on the server are:

• 9600 bps

• 8 data bits

• 1 stop bit

• No parity

• No ﬂow control

✍

Only one of the serial console ports can be used at a time. In Chapter 2, “Installing the Server in a Rack,” see “Front RJ-45 Serial 2 Connector” on page 2-27, and “Rear Panel RJ-45 Serial 2 Connector” on page 2-30 for details on how their ports are conﬁgured.

Rear Panel

Note: When Linux starts communicating over the serial port, it requires hardware ﬂow control

to be enabled.

You can connect to the port if you have an adapter cable that has an RJ-45 connector at one end and a DB9 connector at the other, wired in accordance with Table 8, “Front RJ-45 Serial 2 Port Adapter Pinout,” on page 2-28 of Chapter 2, “Installing the Server in a Rack.” You can then connect the COM1 port of a PC or laptop to the serial console using the adapter cable and use HyperTerminal (or a similar application) to communicate with the server.

An ANSI 500 terminal emulator is needed to have the display appear properly during BIOS setup and when using the diagnostic CD or Service Partition tools.

OM11668A

The intended usage model for the RJ-45 serial connector on the back of the server is for use as an interface to a serial port concentrator, allowing for remote access to the server’s Emergency Management Port (EMP). The serial connector on the front panel can be used as a direct connect to the EMP, allowing for PC-to-PC serial communications to diagnostics on a server mounted in a rack environment.
