3.2 Installing the SFP Transceiver
The sections describe how to insert an SFP transceiver into an SFP port
of the 802.3at PoE+ Switch.
The SFP transceivers are hot-pluggable and hot-swappable. You can plug
in and out the transceiver to/from any SFP port without having to power
down the 802.3at PoE+ Switch, as Figure 3-3 shows.

 Approved PLANET SFP Transceivers
PLANET 802.3at PoE+ Switch supports both single mode and multi-
mode SFP transceivers. The website link of approved PLANET SFP
transceivers is shown below:
https://www.planet.com.tw/en/product/mgb-series-transceiver
Note
It is recommended to use PLANET SFP on the 802.3at
PoE+ Switch. If you insert an SFP trans-ceiver that is not
supported, the 802.3at PoE+ Switch will not recognize it.

1. Before we connect the 802.3at PoE+ Switch to the other network
device, we have to make sure both sides of the SFP transceivers are
with the same media type, for example, 1000BASE-SX to 1000BASE-
SX; 1000BASE-LX to 1000BASE-LX.
2.Check whetherthe ber-opticcabletype matcheswith the SFPtrans-
ceiver requirement.
To connect to 1000BASE-SX SFP transceiver, please use the
multi-mode ber cable with one side being the male duplex LC
connector type.
To connect to 1000BASE-LX SFP transceiver, please use the
