⚫
Keep the router clean and dust-free; do not place the router in the damp place.
2.2.2 Electrical Safety
⚫
Please check whether there are potential dangers. For example, the power is not
grounded, power supply grounding is not reliable, and the ground is wet.
⚫
Before moving the router, be sure to remove all external cables (including power
cable).
⚫
When maintaining with power, it is recommended that there are two or more
persons in the field.
⚫
When closing the power, check and ensure that the power is turned off.
2.2.3 Static Safety
To avoid the static from damaging the electronic parts of the router, we need to take the
anti-static measures.
⚫
When installing the components of the router, especially installing the components
with the circuit board (such as board), we should wear anti-static wrists.
⚫
When holding the circuit board, please hold the edge of the circuit board and do not
touch the components or printed circuit.
⚫
For the security, please check the resistance of the anti-static wrists. The resistance
between the body and the ground should be 1-10 megohms.
The using steps of the anti-static wrists are as follows:
Step 1: Put the hand into the anti-static wrist.
Step 2: Tighten the fastener and ensure that the piece metal on the anti-static wrist is well
contacted with the skin.
Step 3: Insert the anti-static wrist into the anti-static wrist jack on the router chassis or clip the
