with the identifier on the package, and whether any device is damaged or any component is
missing.
Check the pins on the backplane of the chassis. The pins should be straight and clean. Repair
any bent pins on the backplane board slots.
The boards are sensitive to Electrostatic Discharge (ESD). When handling boards, observe the
following rules:

Check whether the device is safely grounded.
Wear an ESD wrist strap during the installation.
Ensure that the metal button on the ESD wrist strap is in complete contact with your skin
and that the other end of the strap (ESD connector) is inserted into the ground point on
the device.
Ensure that the wrist strap is working properly. Its resistance value must be between 0.75
megohm and 10 megohm. If the service life (usually two years) of the wrist strap has
been exceeded or the resistance value fails to meet requirements, replace the wrist strap.
Do not touch the board with your clothes. The ESD wrist strap cannot protect the board
from ESD when it is in contact with clothes.
Wear ESD gloves and place the board on an antistatic pad when replacing the chip of the
board. Use antistatic tweezers or extraction tools to replace chips. Do not touch chips,
circuits, or pins with your bare hands.
Keep the board and other ESD sensitive parts to be installed in antistatic bags. Place the
removed boards and components on an antistatic pad or other antistatic materials. Do not
use non-antistatic materials such as white foams, common plastic bags, or paper bags to
pack boards and do not let such materials touch boards.
Wear an ESD wrist strap when operating the ports of boards as they are also ESD-
sensitive. Discharge the static electricity of cables and protective sleeves before
connecting them to the ports.
Reserve some materials that can hold boards, such as vacuum formed boxes and
antistatic bags, in the equipment room for later use.
If DC power supply is used, ensure that the outputs of the DC power distribution box fall
between -72 V DC and -38 V DC. Two power modules are needed, and each power
module must be connected to two different power sources for redundancy.
If AC power supply is used, ensure that the output voltage of the AC power distribution
cabinet falls between 90 V AC and 175 V AC (with rated input voltage being 110 V) or
between 175 V AC and 264 V AC (with rated input voltage being 220 V) and that two
groups of power modules are provided for redundancy. Meanwhile, two AC power
chassis must be installed on the device.
