5. Verify that the handle on the transceiver is in the upright position or
oriented towards the top of the switch. This secures the transceiver
and prevents it from being dislodged from the slot.
Note
SFP transceivers are dust sensitive. Always keep the protective plug
in the optical bore when a fiber optic cable is not installed, or when
storing the SFP. When you do remove the plug, keep it for future
use.
Note
Unnecessary removal and insertion of an SFP can lead to
premature failure.
For information on the cable specifications of the SFP, consult the
documentation shipped with the SFP.
