Do not install the transceivers with the cables attached. Doing so can damage the cable, the connector, or the optical interface of the transceiver.
Some SD-WAN 4100/5100 appliances do not require SFP+ transceivers.
SD-WAN 4100/5100 appliances do not support 10G SFP+ transceivers provided by vendors other than Citrix Systems. Attempting to install third-party 10G SFP+ transceivers on your SD-WAN 4100/5100 appliance voids the warranty.
Do not look directly into fiber optic transceivers and cables. They emit laser beams that can damage your eyes.
