1, the aspects that should pay attention to hardware (1) the room temperature, and the environment. SPC exchange of room temperature and higher environmental requirements. The more users, the greater the energy consumption, the more the heat emitted by the, so need to run in the constant temperature and clean environment. Room temperature to maintain at 20 ℃ or so, if the temperature is too high, will cause the machine heat dissipation difficulties, make the machine components parameters change, the stability of the circuit is reduced, serious when still can damage the equipment. Pay attention to the temperature at the same time also to keep the room a certain humidity, such as the room is too wet, can make the rust of the metal parts of the machine, equipment corrosion, even will cause the line insulation is reduced, the phenomenon such as short circuit. Room is too dry, easy to produce static electricity, directly threatens the safety of the switch. According to regulations, computer room humidity shall be maintained at 40% ~ 60%. Such as temperature and humidity can be thermometer monitoring, when necessary, can install air conditioning, humidification machine or smoke wet machine, etc. In addition, the room also requires fire and dust prevention measures, want serious jam after cable duct construction, in order to prevent small animals to enter. (2) the electrostatic prevention measures. SPC exchange circuit adopt large scale and very large scale integrated circuit operation. The higher level of integration, the level of voltage resistance and impact resistance and the lower accordingly. And the voltage generated by the electrostatic sometimes as high as dozens, hundreds, thousands or tens of thousands of volts, so high electrostatic voltage is enough to destroy a chip, or damaged so electrostatic effect of program-controlled switches greatly threatened. For laying anti-static floor machine room floor, therefore, electrostatic slippers to relief work crew entered the room, while touching the equipment, should wear anti-static gloves when plug circuit board. When working in the computer room should not be walking back and forth repeatedly running, in order to prevent the static friction.
2 management software, the need to do some (1) pay close attention to the machine's running status, found that all kinds of alarm information in a timely manner. (2) check the operation and maintenance terminal, billing system, switch, printer, etc is a state of normal work. (3) different types of standby circuit board is keeping well. (4) after major operation, should be timely information database, copying and printing switches and seriously custody, according to the rules for a rainy day. (5) check the lightning protection device on the audio distribution frame, insurance arrangement is effective. To prevent damage due to line fault from outside into alternating current machine. |
