Port Description
MGMT Port
(PoH IN Port)
The RJ45 Management (MGMT) port is an IP-based, Out-Of-Band (OOB) port for
Telnet, Web, or SNMP management that operates at 10/100/1000 Mbps wire-
speed. This port can be used to configure the Switch without being connected to
the network.
The MGMT port can also be used to supply the Switch with 90W DC power using
Power over HDBaseT. This can be used as the main power source or as the
secondary power source to the Switch.
