If abnormality is found in the fan, replace the faulty fan. For operation details, refer to ZXG10 iBSC (V6.20) Base Station Controller Installation Manual.
Checking Anti-Static Wrist Strap
In dry environment, the static electricity accumulated in human body might cause high-voltage static electricity. If the operator touches the electronic devices with static electricity in the body, the device might be damaged. Wearing the anti-static wrist strap can discharge the static electricity in human body and avoid device damage. Therefore, the operator must wear the anti-static wrist strap before touching the equipment, and holding the board, circuit board, or IC chip. The other end of the anti-static wrist strap must be well grounded.
Check the anti-static wrist strap of each rack and make sure that they are installed in correct positions and have good contact.
Checking Spare Materials and Parts
Perform the following steps to check the spare materials and parts.
1. Check the spare materials and parts with the list of spare materials and parts.
2. For common spare materials and parts, supplement them in time if they are used up.
