- Capable of providing up to 500 W of continuous power per power supply
- Limited to TNV-2 as defined by UL 60950 and IEC 60950
|
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.
|
DC Supply and Ground Conductor Requirements
- Suitable conductor material: Use copper conductors only
- Power supply connections through the input connector: 12 AWG (between the Netra 440 server and the source). There are three conductors:
- -48V (negative terminal)
- Chassis ground connection
- -48V Return (positive terminal)
- System ground conductor: 12 AWG (to be connected to the chassis)
- Cable insulation rating: Minimum of 75°C (167°F), low smoke fume (LSF), flame retardant
- Only one of the following cable types:
- UL style 1028 or other UL 1581(VW-1) compliant equivalent
- IEEE 383 compliant
- IEEE 1202-1991 compliant
- Branch circuit cable insulation color: According to applicable National Electrical Codes
- Grounding cable insulation color: Green/yellow
Overcurrent Protection Requirements
- Overcurrent protection devices must be provided as part of each equipment rack.
- Circuit breakers must be located between the DC power source and the Netra 440 server. Use one 20 A, double-pole, fast trip DC-rated circuit breaker for each power supply unit.
|
Note - Overcurrent protection devices must meet applicable national and local electrical safety codes, and must be approved for the intended application.
|
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:
- Toward the front air intake of the server
- Toward the server access panels
|
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.
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:
- Prevent corrosion
- Provide an operating time buffer in the event of environmental control system failure
- Help avoid failures caused by the intermittent interference from static discharges that occur when relative humidity is too low
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
- Ensure unobstructed airflow through the chassis.
- Inlet air enters at the front of the server and exits from the back.
- Ventilation openings such as cabinet doors, for both the inlet and exhaust of the server should provide a minimum open area of 215 cm2 (33.325 in2) each. This equates to a 60% open area perforation pattern across the front and rear area of the server (445 mm x 81 mm; 17.5 in x 3.2 in). The impact of other open area characteristics that are more restrictive should be evaluated by the user.
- Front and rear clearance of the server should allow a minimum of 5 mm (.2 in) at the front of the system and 80 mm (3.1 in) at the rear of the server when mounted. These clearance values are based on the above inlet and exhaust impedance (available open area) and assume a uniform distribution of the open area across the inlet and exhaust areas. Clearance values greater than these are recommended for improved cooling performance.
|
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).
|
- Care should be taken to prevent recirculation of exhaust air within a rack or cabinet.
- Cables should be managed to minimize interfering with the server exhaust vent.
- Air temperature rise through the system is approximately 15°C (59°F).
Acoustic Noise Emissions
The acoustic noise emissions on a Netra 440 server are as follows:
- Operating acoustic noise is 7.0 B (LWAd (1B=10dB))
- Idling acoustic noise is 7.0 B (LWAd (1B=10dB))
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 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).
Sun Advanced Lights Out Manager
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:
- ALOM is active as soon as the server is connected to a power source, and remains active until power is removed by unplugging the power cables.
- ALOM continues to be effective even when the operating system is offline and when the server is in Standby mode.
TABLE 1-7 lists the components monitored by ALOM and describes the information provided for each component.
