2.2 Temperature Control Unit
2.2.1 Overview
The temperature control unit of the TP48200A-D17B6 is composed of a direct-cooling unit
and a heater. The direct-cooling unit accelerates the air ventilation and adjusts the temperature
inside the cabinet by using an air-exhaust device, an air-intake device, an air filter, and a fan
assembly. The heater keeps the internal cabinet at an optimal operating temperature.
The direct-cooling unit and heater do not work simultaneously.
The TP48200A-D17B6 with a direct-cooling unit adjusts the fan speed based on the ambient
temperature and the temperature inside the cabinet. If the ambient temperature is far below the
temperature inside the cabinet or the temperature inside the cabinet is lower than the
minimum value, the TP48200A-D17B6 stops the fan. This function saves energy because the
TP48200A-D17B6 is cooled by external air.
Air flows
The direct-cooling unit direct air into the cabinet through the lower part of the door and out of
the cabinet through the upper.

3.1 Overview
To minimize the risk of personal injury and damage to equipment, read and follow all the
precautions in this document before performing any installation or maintenance. The "NOTE",
"CAUTION", and "WARNING" marks in other documents do not represent all the safety
instructions. They are only supplements to the safety instructions. Only trained and qualified
personnel are allowed to install, operate, and maintain Huawei equipment, and they must
understand basic safety precautions to avoid hazards.
To ensure safety of humans and the equipment, pay attention to the safety symbols on the
equipment and all the safety instructions in this document. Huawei will not be liable for any
consequence caused by the violation of the safety operation regulations and design,
production, and usage standards.
The safety precautions described in this section are also applicable to other Huawei equipment.
3.2 Local Safety Regulations
When operating Huawei equipment, you must follow the local laws and regulations. The
safety instructions in this document are only supplements to the local laws and regulations.
3.3 Grounding Requirements
Equipment to be grounded must meet the following requirements:
When installing the device, always make the ground connection first and disconnect it at
the end.
Do not damage the ground conductor or operate the device in the absence of a properly
installed ground conductor. Conduct the electrical inspection carefully.
CAUTION
NOTE
TP48200A-D17B6
User Manual 3 Safety Precautions
Issue 01 (2012-07-13) Huawei Proprietary and Confidential

43
The device (or system) must be connected permanently to the protection ground before
an operation. Before operating the device, check the electrical connection of the device
to ensure that it is securely grounded.
3.4 Human Safety Do not operate the device or cables during lightning strikes.
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telecommunication network voltage (TNV) circuits.
Before operating the device, wear electrostatic discharge (ESD) clothes, ESD gloves, and
an ESD wrist strap.
Do not wear jewelry or watches when you operate the device.
In the case of fire, immediately leave the building or the equipment room, and turn on
the fire alarm bell or make an emergency call. Do not enter a building that is on fire.
The temperature of some equipment parts may be rather high. Do not touch the surface
of such equipment parts to avoid getting burn.
3.5 Equipment Safety The device must be fixed securely on the floor or to other immovable objects such as
walls and mounting racks before operation.
Do not block the ventilation while the device is operating.
Tighten the thumbscrews by using a tool after initial installation and subsequent access
to the panel.
After the installation, remove packing materials from the equipment area.
3.6 Electrical Safety
High Voltage
The high voltage power supply provides power for the device operation. Direct or indirect
contact (through damp objects) with high voltage and AC mains supply may result in fatal
danger.
Non-standard and incorrect high voltage operations may result in fire and electric shock.
The personnel who install the AC facility must be qualified to perform high voltage and
AC operations.
You must abide by the local rules and regulations when bridging and wiring AC cables.
During the installation of the AC power supply facility, follow the local safety
regulations.
DANGER
TP48200A-D17B6
User Manual 3 Safety Precautions
Issue 01 (2012-07-13) Huawei Proprietary and Confidential
Copyright © Huawei Technologies Co., Ltd
44
Dedicated tools must be used during high voltage and AC operations. Avoid using
ordinary tools.
When the operation is performed in a damp environment, ensure that the device is dry.
When water is found in the rack or the rack is damp, switch off the power supply
immediately.
High Electrical Leakage Ground the device before powering it on. Otherwise, personal injury or device damage
may be caused by high leakage current.
If a "high electrical leakage" tag is present on the power terminal of the device, you must
ground the device before powering it on.
Power Cable Do not install or remove power cables when the device is on. Transient contact between
the core of the power cable and the conductor may generate electric arcs or sparks, which
may cause fire or hurt human eyes.
Before installing or removing the power cable, turn off the power switch.
Before connecting a power cable, check that the label on the power cable is correct.
Power Output
All output circuits are evaluated as SELV circuits.
Outputs are energy hazards (>240 VA)
Electrostatic Discharge
The static electricity generated by human bodies may damage the electrostatic-sensitive
components on boards, for example, the large-scale integrated (LSI) circuits.
Human body movement, friction between human bodies and clothes, friction between
shoes and floors, or handling of plastic articles causes static electromagnetic fields on
human bodies. These static electromagnetic fields cannot be eliminated until the static is
discharged.
To prevent electrostatic-sensitive components from being damaged by the static on
human bodies, you must wear a well-grounded ESD wrist strap when touching the
device or handling boards or application-specific integrated circuits (ASICs).
