Nvidia MMA4Z00-NS Manual page 32

The transceiver can be damaged by exposure to current surges and over voltage events.
Take care to restrict exposure to the conditions de ned in Absolute Maximum Ratings.
Observe normal handling precautions for electrostatic discharge-sensitive devices.
The transceiver is shipped with dust caps on both the electrical and the optical port. The
cap on the optical port should always be in place when there is no ber cable connected.
The optical connector has a recessed connector surface which is exposed whenever it has
no cable nor cap.
Important note 1: Keep both the ber and transceiver dust caps.
Important note 2: Clean both transceiver receptacle and cable connector prior to insertion
of the ber cable, to prevent contamination from it.
The dust cap ensures that the optics remain clean during transportation. Standard
cleaning tools and methods should be used during installation and service. Liquids must
not be applied.
Important note 3: 80% of transceiver link problems are related to dirty optical connectors .
