2.5.3 Connecting to SFP fiber combo ports 
The small form-factor pluggable (SFP) module is a compact, hot-pluggable transceiver used for optical 
signal transmission. The module bay is a combo port, sharing a connection with an RJ45 port. Being a 
combo port, only one type of connection can be active at any given time. For example, both copper and 
fiber port cannot be used at the same time. If both connectors are plugged in at the same time, the fiber 
port becomes active. 
The SFP module accommodates a standard SFP module with an LC connector.

camera) to switch. By default, the power supply mode is dynamic, PoE power supply is enabled and the 
power supply standard is 802.3at.
