6-1 6 Maintenance and Troubleshooting Software Loading Failure If software loading fail s, the system keeps runni ng in or iginal version. In this case, check if the physical ports are properly conn ected. z If the ports are not properly connected, reco nnect th em correctly and re start the loading procedure.
6-2 Power Supply Failure The Switch 4210G use fixed power modules. Ea ch of the Switch 4210G has three input mode s, namely , AC input, RPS input and both. Y ou can check whether the power syst e m of the switch fails by view ing the sy stem status LED (PWR) and RPS status LE D (RPS) on the front pan el of the switch.
6-3 z Check whethe r the AC power cord is well c onnecte d to the switch, whether the AC receptacle on the switch and the AC power socket are faulty. z Check whether the AC extern al po wer supply system is normal. z Check whether the switch is we ll connect ed to the external RPS power supply.
6-4 The Switch 4210G switche s use fixed fans. If a fixed fan failure occurs, you cannot solve the problem by yourself. Please contact your sales age nt or service engineer . To ensure the normal operation of the swit ch, you need to contact the local sales agent or service engineer as soon as po ssible when a fixed fan failure occurs.
