Guide Pins forDSX-5000/8000 Copper Modules

After many studies and field tests, it was found that the guide pins on the DSX-5000 andDSX-8000copper 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.

經過多次研究和現場測試，發現dsx-5000和dsx2-8000銅模組上的導銷是冗餘的。與帶有導向銷的單元相比，沒有導向銷的單元的測試在效能上沒有差異。

福祿克維修中心在2019年1月釋出告知，如果在維修或校準過程中遇到鬆動的導銷，應將導銷從銅模組上拆下。別針鬆動是很少見的。如果仍然連線良好，服務中心將不採取任何行動。
