Huawei NetEngine 8000 F User Manual

Personnel Safety
● A high-voltage power supply provides power for device operations. Direct
human contact with the high voltage power supply or human contact through
damp objects can be fatal.
●
Unspecied or unauthorized high voltage operations could result in re or
electric shock, or both.
● Ground a device before powering it on; otherwise, the human body and the
device are exposed to danger.
● Before performing operations on the power supply facilities, power o these
facilities.
● Do not look into the optical port without eye protection when handling
optical
bers.
● To protect human respiratory organs and human eyes from dust, take
protective measures when drilling holes.
● When working at heights, prevent objects from falling down.
Device Security
● Keep an unpacked device upright and handle it with care when carrying it or
installing it into a cabinet.
● Use a ladder to lay out cables. Do not trample on a device.
● Wear an ESD wrist strap or ESD gloves when handling circuit boards.
Otherwise, the static electricity discharged from the human body may
damage the electrostatic sensitive components, such as large-scale integrated
circuits (LSIs) on the circuit board.
● Before operating the device, check the electrical connection of the device, and
ensure that the device is properly grounded.
Power Module
● After a power module enters the protection state, it cannot supply power. If
the power module cannot automatically resume power supply after the
triggering condition of the protection state is removed, remove the power
module from the chassis and reinstall it at least 30s later. The power module
then can work properly.
● When a power module enters overtemperature protection state, take
measures to lower the temperature of the chassis. The power module can
automatically resume power supply when the temperature falls within the
normal range.
Cable
● To protect personal safety, do not install power cables when the power is on.
Before connecting power cables, make sure that the power switches of the
external power supply system and the device are all in OFF position.
● Before connecting signal cables, take ESD protection measures, for example,
wear ESD gloves or an ESD wrist strap.
● Before connecting Ethernet cables, use an Ethernet cable tester to test cable
connectivity.
