This chapter contains a description of the Netra 240 server and provides the installation site requirements. The chapter contains the following sections:


Overview

The Netra 240 server is a two rack unit (RU) server with one or two processors.

  FIGURE 1-1 Netra 240 Server

Figure showing the Netra 240 server.

The Netra 240 server uses either one or two UltraSPARC® IIIi processors. The server depth enables mounting in standard rack depths of 24 inch, 600 mm, or deeper.

Storage is provided by two hot-swappable disk drives, together with an optional non-hot-swappable slimline DVD-RW or DVD-ROM drive. Built-in I/O functionality is provided by four Gigabit Ethernet channels, and two SCSI channels (one for external and one for internal use). Two independent open host controller interface (OHCI) USB hubs are also provided. I/O expansion is provided with one full-length PCI card slot supporting both 33MHz and 66MHz cards, and two half-length PCI card slots supporting 33MHz cards. A dry contact relay alarm card for remote management control (RMC) firmware and an alarm status LEDs card are provided.

Sun Advanced Lights Out Manager

The Netra 240 server ships with the Sun Advanced Lights Out Manager (ALOM) software preinstalled. By default, the system console is directed to ALOM and is configured to show server console information on startup.

ALOM enables you to monitor and control your server over either a serial connection (using the SERIAL MGT port), or Ethernet connection (using the NET MGT port). See Connecting the Data Cables for the location of these and other ports. For information about configuring an ALOM Ethernet connection, refer to the Sun Advanced Lights Out Manager User Guide for the Netra 240 Server
(817-3174).



Note - The ALOM serial port, labelled SERIAL MGT, is for server management only. If you need a general purpose serial port, use the serial port labeled 10101. See Rear Cable Connections for the location of these serial ports.



ALOM can be configured to send email notifications of hardware failures and other events related to the server or to ALOM.

The ALOM circuitry uses standby power from the server, which means:

TABLE 1-3 lists the components monitored by ALOM and describes the information provided for each component.

Sun Install Check Tool

The Netra 240 server supports the Sun Install Check tool, which can confirm that your server has been installed successfully. The Install Check software checks the initial server installation and tests your server for:

If potential issues are identified, the software generates a report with specific instructions to remedy the issues.

You can download the Sun Install Check tool software and documentation at:

http://www.sun.com/software/installcheck/


Sun Remote Services Net Connect Support

The Netra 240 server supports the Sun Remote Services (SRS) Net Connect monitoring services. The SRS Net Connect web services give you the ability to self-monitor systems, create performance and trend reports, and receive automatic notifications, so you can act more quickly when a system event occurs and manage potential issues before they become problems.

For more information about SRS Net Connect, including how to sign up and download the documentation, refer to the SRS Net Connect web site at:

http://www.sun.com/service/support/srs/netconnect/


Note - The Net Connect Installation Guide contains installation instructions specific to the Netra 240 server. This guide can be downloaded after signing up for the service.




Installation Site Requirements

Recommended Operating Environment

Your environmental control system must provide intake air for the server which complies with the limits specified in Environmental Requirements.

To avoid overheating, do not direct warmed air:



Note - When you receive your system, place it in the environment in which you will install it. Leave it in its shipping crate at its final destination for 24 hours. This resting period prevents thermal shock and condensation.



The system has been tested to meet all functional requirements when operating in the operating environmental limits in TABLE 1-5. Operating computer equipment in extremes of temperature or humidity increases the failure rate of hardware components. To minimize the chance of component failure, use the server within the optimal temperature and humidity ranges.

Ambient Temperature

An ambient temperature range of 21°C (69.8°F) to 23°C (73.4°F) is optimal for system reliability. At 22°C (71.6°F) it is easy to maintain safe relative humidity levels. Operating in this temperature range provides a buffer if the environmental support systems fail.

Ambient Relative Humidity

Ambient relative humidity levels between 45% and 50% are the most suitable for data processing operations in order to:

Electrostatic discharge (ESD) is easily generated and less easily dissipated in areas where the relative humidity is below 35%, and becomes critical when levels drop below 30%.

Airflow Considerations

The Netra 240 server uses internal blowers that can achieve a total airflow of
1.42 m3/min (50 CFM) in normal operating conditions.



Note - The combination of inlet and exhaust restrictions such as cabinet doors and the spacing of the server from the doors can affect the cooling performance of the system and should be evaluated by the user. The server placement is particularly important for high temperature NEBS environments where the server inlet ambient temperature is 55°C (131°F). (The DC-powered server is NEBS compliant.)



Acoustic Noise Emissions

The acoustic noise emissions on a Netra 240 server are as follows:

Declared noise emissions are in accordance with ISO 9296 standards.

Calculating Heat Dissipation

To calculate the heat generated by a server so that you can estimate the heat your cooling system must dissipate, convert the figure for the system's power requirement from Watts to BTU/hr. A general formula for doing this is to multiply the power requirement figure in Watts by 3.412.

NEBS Level 3 Compliance

Telcordia certified that the DC-powered version of the Netra 240 server meets NEBS Level 3 requirements per SR-3580, including the appropriate sections of GR-63-CORE (Network Equipment-Building System Requirements: Physical Protection) and GR-1089-CORE (Electromagnetic Compatibility and Electrical Safety - Generic Criteria for Network Telecommunications Equipment).



caution icon

Caution - To maintain NEBS compliance, the network management (NET MGT) Ethernet port and the RJ-45 serial management (SERIAL MGT) port must use shielded cables and both ends of the shield must be grounded. See Rear Cable Connections for cabling information.




1 (TableFootnote) Short term (no more than 96 hours) temperature and humidity limits apply to servers with altitudes up to 1800 m (5905.44 ft.).
