method is specific for RG-S12000 chassis using AC power.
RG-S12000 Grounding Steps
Release and remove the nut on the grounding pole of the chassis back.
Cover the terminal of the grounding cable on the grounding pole.
Tighten the nut into the grounding pole.
Connect the other end of the grounding cable to the grounding pole or grounding bar of the
machine room.
Static Electricity Prevention
To avoid the damages from static electricity to the internal parts of switches, do as follows:
Static electricity prevention measures are taken in the sites where switches are installed.
Wear antistatic wrist strap to install various switch parts, especially when you may touch circuit
boards with hands.
Grasp the edge of modules. Do not touch the parts or printed circuits directly.
The antistatic wrist strap is shipped with RG-S12000, which is used as follows:
1.
Stretch out your hand into the antistatic wrist strap.
2. Lock the wrist strap and make sure that the metal part of the antistatic wrist strap is in good
contact with skin.
3.
Insert the antistatic wrist strap in the antistatic wrist strap jack of the switch chassis or clip on the
grounding pole of the chassis. The antistatic wrist strap jack is located on the front panel of the
chassis marked with yellow ESD.
4.
The antistatic wrist strap is grounded well and the DC electric resistance between the body and
the ground is in the range of 1 to 10 mega ohm.
Common Troubleshooting Procedures
Fault 1: The AC power module does not work.
[Fault Description]
The Status LED of each line card is OFF, the Power LED of the fan tray is OFF, and the fan does not
work. The LED on the panel of the power module is OFF.
[Troubleshooting]
1. Place the switches of all the power modules to OFF. Check if the cables of the cabinet have
been correctly connected.
2. Check whether the power cables are tightly connected to the cabinet power sockets and power
modules.
3. Check whether the power modules are installed correctly. If necessary, check whether the
connectors on the backplane of the power system are tightened.
4. Check whether the supply power output consumption meets the overall power consumption
requirements. If it is less than the power required by the system, please purchase another power
module.
Fault 2: An exception occurs to the LEDs when line cards are powered on.
[Fault Description]
The Status LED of the line card is OFF, flashing, or RED. The Link/ACT LED of the line card is solid
ON when no network cable or fiber is plugged.
