Preparing for Installation
This chapter includes a description of the components of the Netra 440 server and a set of questions that the system administrator must answer before installing the server software.
This chapter contains the following sections:
Standard components of Netra 440 servers are installed at the factory. However, if you ordered options such as a PCI card and monitor, these are shipped to you separately.
Check that you have received everything you ordered.
Note - Inspect the shipping carton for evidence of physical damage. If a shipping carton is damaged, request that the carrier's agent be present when the carton is opened. Keep all contents and packing material for the agent's inspection.
Verify that you have received all the parts of your system. See the illustration below to identify most of the parts shipped with the system.

This section provides the specifications and site requirements you may need when planning the installation of the Netra 440 server. For safety and compliance information, refer to the Netra 440 Safety and Compliance Manual (817-6225-xx) and the Important Safety Information for Sun Hardware Systems document (816-7190-xx) that came with your system.
You can operate and store the Netra 440 server safely in the conditions detailed in TABLE 1-2.
The information in this section applies to the AC version of the Netra 440 server. TABLE 1-3 gives AC power source requirements for each power supply in the Netra 440 server, and TABLE 1-4 gives AC power source requirements for the Netra 440 server as a whole.
Note - The figures for the maximum operating current are provided to help you specify the fusing and cabling you need to deliver power to your equipment. However, these figures represent worst-case scenarios.
The information in this section applies to the DC version of the Netra 440 server. TABLE 1-5 gives DC power source requirements for each power supply in the Netra 440 server, and TABLE 1-6 gives DC power source requirements for the Netra 440 server as a whole.
Note - The DC version of the Netra 440 server must be installed in a restricted-access location. According to the intent of the National Electrical Code, a restricted-access location is an area intended for qualified or trained personnel only and has access controlled by a locking mechanism, such as a key lock or an access card system.
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 presented in Environmental Requirements. 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.
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 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%.
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 acoustic noise emissions on a Netra 440 server are as follows:
Declared noise emissions are in accordance with ISO 9296 standards.
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.
Telcordia certified that the DC-powered version of the Netra 440 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).
The Netra 440 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 Chapter 4 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 440 Server (817-5481-xx).
Note - The ALOM serial port, labelled SERIAL MGT, is for server management only. If you need a general purpose serial port, use the standard TTYB serial port. See Chapter 4 for the location of these serial ports.
ALOM can be configured to send e-mail 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 1-7 lists the components monitored by ALOM and describes the information provided for each component.
The Netra 440 server supports the Sun Install Check tool, which can confirm that your server has been installed successfully. The Install Check software is designed to check the initial server installation and tests your server for:
If potential issues are identified, the software generates a report that provides specific instructions to remedy the issues.
You can download the Sun Net Connect software and documentation at:
The Netra 440 server supports the SunSM 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.
