Installing Optional SFP Transceivers
To install an SFP transceiver, perform the following procedure:
Note
The transceiver can be hot-swapped; you do not need to power off
the switch to install a transceiver. However, always remove the
cables before removing the transceiver.
Note
You should always install the transceiver before connecting the fiber
optic cables to it.
1. Remove the transceiver from its shipping container and store the
packaging material in a safe location.
Warning
An SFP transceiver can be damaged by static electricity. Be sure to
observe all standard electrostatic discharge (ESD) precautions,
such as wearing an antistatic wrist strap, to avoid damaging the
transceiver.
2. Remove the dust plug from an SFP slot. See Figure 12.
