Huawei USG6000E Series - A.1.3 ESD Requirements

Item Description
Storage humidity ● Without hard disk: 5% RH to 95% RH, non-
condensing
● With hard disk(s): 5% RH to 90% RH, non-
condensing
To meet the requirements listed in Table A-2, take the following measures in the
equipment room:
● Install a permanent temperature controller regardless of the climate
conditions.
● In dry regions, use humidiers or regularly mop the oor to ensure proper
humidity in the equipment room.
● In regions with high humidity, use
dehumidiers.
● Use dust-free materials for the oor, walls, and ceilings.
● Screen exterior doors and windows. The external windows of the equipment
room should be sealed for anti-dust purposes.
● Clean the equipment room and air
lters on the devices once every three
months.
● Wear the ESD uniform, ESD gloves, and ESD shoes before entering the
equipment room.
● Locate the equipment room far away from areas with dense corrosive gases,
such as chemical plants.
● The air intake vent of the equipment room must not face any pollution
source.
● Place batteries in a dierent room from the devices.
● Invite professionals to measure the temperature, humidity, and other factors
periodically.
A.1.3 ESD Requirements
This section describes the ESD requirements. Ensure that the equipment room
meets these requirements because static electricity may damage the USG
components and cause the USG to malfunction.
The absolute value of the static voltage must be less than 1000 V. To meet the
requirement, take the following measures in the equipment room:
● Provide operators with ESD protection training.
● Adjust the humidity to reduce the impact of static electricity.
● Install an ESD oor in the equipment room.
● Wear an antistatic suit, ESD gloves, and antistatic shoes before entering the
equipment room.
● Use ESD tools, such as ESD wrist straps, ESD tweezers, and extractors.
● All the conductors in the equipment room, including computer terminals,
must be properly grounded. Set up an antistatic workbench.
