After many studies and field tests, it was found that the guide pins on the DSX-5000 and DSX-8000 copper modules are redundant. Tests with units with no guide pines have shown no variance in performance compared to tests with units with guide pins.
In a Service Alert issued in January of 2019, the worldwide service centers were advised that if they come across loose guide pins during repair or calibration procedures, the pins should be removed from the copper modules. It is uncommon for the pins to come loose. If they are still well connected, no action will be taken by the service center.
经过多次研究和现场测试,发现dsx-5000和dsx2-8000铜模块上的导销是冗余的。与带有导向销的单元相比,没有导向销的单元的测试在性能上没有差异。
福禄克维修中心在2019年1月发布告知,如果在维修或校准过程中遇到松动的导销,应将导销从铜模块上拆下。别针松动是很少见的。如果仍然连接良好,服务中心将不采取任何行动。
