do not, the cable's electrostatic discharge (ESD) may damage the Switch's
port.
You can create a grounded port by connecting all wires at one end of a
UTP cable to an earth ground point, and the other end to a female RJ-45
connector located, for example, on a Switch rack or patch panel. The
RJ-45 connector is now a grounded port.
The following sections describes how to insert and remove an SFP
transceiver into an SFP port.
SFP transceivers are hot-insertable and hot-swappable. You can remove
them from and insert them into any SFP port without having to power off
the Switch.
The following list of approved SFP transceivers is correct at the time of
publication.
