Power Source Requirements
The server has two hot-swappable power supplies. Both the AC and the DC power
supplies are capable of current sharing. To ensure redundant operation of the power
supplies, connect the two power cords to separate circuits.

Caution – WARNING: The intra-building port(s) of the equipment or subassembly
is suitable for connection to intrabuilding or unexposed wiring or cabling only. The
intra-building port(s) of the equipment or subassembly MUST NOT be metallically
connected to interfaces that connect to the OSP or its wiring. These interfaces are
designed for use as intra-building interfaces only (Type 2 or Type 4 ports as
described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP
cabling. The addition of Primary Protectors is not sufficient protection in order to
connect these interfaces metallically to OSP wiring.

Netra X4200 M2 Server Site Planning Guide • May 2008
Recommended Operating Environment
Your environmental control system must provide intake air for the server that
complies with the limits specified in “Environmental Specifications” on page 2.
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 server, place it in the environment in which you will
install it. Leave the server in its shipping crate at its final destination for 24 hours.
This resting period prevents thermal shock and condensation.
The server has been tested to meet all functional requirements when operating in the
operating environmental limits presented in “Environmental Specifications” on
page 2. 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.
Electrical Power
Good practice is to connect each power supply to a separate circuit, which enables
the server to remain operational if one of the circuits fails. Consult your local
electrical codes for any additional requirements.
Surge Protector Devices
An external Surge Protection Device (SPD) is not intended to be used at the AC
input of this network equipment. The Netra X4200 server meets NEBS criteria
without the addition of an SPD.
Chapter
Netra X4200 M2 Server Site Planning Guide
5
Ambient Temperature
An ambient temperature range of 21˚C (69.8˚F) to 23˚C (73.4˚F) is optimal for server
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
6
■
Ensure that there is unobstructed airflow through the chassis. The server uses
internal blowers that can achieve a total airflow of 120 CFM (3.4 m3/min) in
normal operating conditions.
■
Ensure that inlet air enters at the front of the server and exits from the back.
■
Ensure that ventilation openings such as cabinet doors, for both the inlet and
exhaust of the server, provide a minimum open area of 35.5 in.2 (231 cm2) each.
This equates to a 60% open area perforation pattern across the front and rear area
of the server. The impact of other open area characteristics that are more
restrictive should be evaluated by the user.
■
Ensure that front and rear clearances between the cabinet doors and the server
allow a minimum of 0.2 in. (5 mm) at the front of the server and 3.15 in. (80 mm)
at the rear of the server when the server is 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.
Netra X4200 M2 Server Site Planning Guide • May 2008
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
server 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.)
■
Take care to prevent recirculation of exhaust air within a rack or cabinet.
■
Manage cables to minimize interference with the server exhaust vent.
■
Ensure that air temperature rise through the server is no greater than 68˚F (20˚C).
Acoustic Noise Emissions
The acoustic noise emissions on the server are listed below:
Parameter

Idling
Acoustic power LWAd (1B=10dB)
7.1 B
7.2 B
Acoustic pressure LpAm
58.9 dBA
59.0 dBA
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 server’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 Certification
Telcordia certified that the DC-powered version of the 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 – 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.
