Power Consumption - Huawei OptiX OSN 8800 Hardware Description

OptiX OSN 8800/6800/3800
Hardware Description
Item
a: Rotating speed of fans is controlled intelligently. When the system is typically
configured, rotating speed of fans is automatically adjusted to a low level. When the system
is fully configured with boards of high power consumption, and the system is running in a
high ambient temperature, rotating speed of fans may be adjusted to a high level. When
rotating at the maximum speed, power consumption of fan tray assembly may reach 215 W.

Issue 01 (2016-03-10)
describes the power consumption of an OptiX OSN 8800 T16 subrack.
For transport equipment, the heat consumption and power consumption are similar and can be
considered the same. Heat consumption is expressed in BTU/h and power consumption is expressed in
W. The conversion between the two units is as follows: 1 BTU/h = 0.2931 W.
Typical configuration power consumption indicates the average power consumption of the equipment
with the typical configuration and the equipment runs at the room temperature. Maximum power
consumption indicates the possible maximum power consumption when the equipment runs in an
environment with extreme conditions.

Specification
Class B environment: refers to the indoor environment

where the ambient temperature and humidity are not
controlled or the common outdoor environment where
only simple shelter (such as awning) is available and the
humidity occasionally reaches 100%.
The average life spans of fan tray assemblies in different
environments are as follows:
Class A environment: 6.5 years

Class B environment: 5 years

NOTE
The previous life spans are the average values concluded based on the
test data in a lab and the theoretical model, rather than the actual
values. They are for reference only. The actual life span must be
determined based on the environment conditions of a specific area. In
addition, the previous life spans do not indicate that a fan tray
assembly becomes unavailable immediately at the end of its life span.
They are used to prompt users to replace the fan tray assembly in
time.
