Safety of Personnel • The high voltage power supply provides power for running the system. Direct contact with the high voltage power supply or contact through damp objects may result in fatal danger. • Non-standard and improper high voltage operations may result in fire and electric shock. • In a thunderstorm, do not perform operations on high voltage and AC power supply facilities or on a steel tower and mast. • Ground the device before powering on the device. Otherwise, the personnel and device are in danger. • Power off the device before performing operations on the power supply equipment. • High power radio-frequency signals are harmful to human body. Before installing or maintaining an antenna on a steel tower or mast with a large number of transmitter antennas, the operator should coordinate with all parties to ensure that the transmitter antennas are shut down. • When handling optical fibers, do not stand close to, or look into the optical fiber outlet with unaided eyes. • Protect yourself when drilling holes. Flying dust may hurt your eyes or you may inhale the dust. • Power off the batteries before connecting the cables to the batteries. Otherwise, casualties may occur. • When working at a height, be cautious about falling objects. Device Safety • Check the electrical connection of the device before operation and ensure that the device is reliably grounded. • The static electricity generated by the human body may damage the electrostatic sensitive components on the circuit board, such as the large-scale integrated circuit (LIC). Wear an ESD wrist strap or ESD gloves when performing the operation. • When working on batteries, take measures to prevent short circuits in the batteries and electrolyte spill/loss. The electrolyte may erode metal and boards, or even cause rust of the equipment or short circuits in the boards. • When the equipment is unpacked, it must be powered on in 24 hours. The maximum duration of the poweroff state of the equipment is 24 hours during maintenance. Copyright © Huawei Technologies Co., Ltd. 2009. All rights reserved.
