终端的使用有其自身的特点。它可以直接使用市电,而不需要稳压电源、空调装置等,可以用在各种环境,所以相对于计算机来说,其工作环境要恶劣得多,故障率也就较高。 终端常见故障表现为,无显示或不联机。检查的方法是:先看外因,即市电正常否,交换终端看信号电缆通讯是否正常。再交换终端,看是网络卡的故障还是终端本身的故障,如确实是终端本身故障,再查内因。
The use of terminals has its own characteristics. It can directly use mains, without the need for regulated power supplies, air conditioners, etc. It can be used in a variety of environments, so its working environment is much worse and its failure rate is higher relative to computers. Terminal common fault performance, no display or not online. Check the method is: first look at external factors, that is normal electricity, the exchange terminal to see the signal cable communication is normal. Then exchange the terminal, see the network card is the fault or the terminal itself, such as failure is indeed the terminal itself, and then check the internal.
