Check for a green or blinking LED light on your device. If you see no light or a red light, take the module out and try again.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >What should you do if an optical module feels stuck?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Stop and look at the latch. Open it gently without using too much force. If the module still will not move, check your device manual. Forcing it can break the port or the module.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >Can you install or remove optical modules while the device is powered on?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some devices let you swap modules while they are on. Always read your manufacturer\u2019s guide first. If you are not sure, turn off the device before you add or remove any module.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >How often should you clean optical connectors?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Clean connectors every time before you connect or unplug them. Use a fiber cleaning kit for the best results. Dirty connectors can make the signal weak and harm your equipment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >What is the best way to store unused optical modules?<\/h3>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Keep unused modules in anti-static bags or boxes.
