Fiber-optic modules
• Packet loss
Before inserting the fiber cable into the fiber-optic transceiver, ensure that it is free of dust by
cleaning the end. A “Fiber Swiper” cleaner is provided by Brocade for this purpose with each optic
shipment (reference instructions provided with the Fiber Swiper).
It is very important that the end of an optical cable is clean when using any data rate. This must be
the first step in troubleshooting symptoms such as those stated previously. Always ensure that the
optical cables are cleaned.
NOTE
When not using a fiber-optic module port connector, replace the protective cover to prevent dust or
dirt from contaminating the connector.
