DIP Switch Explanation
Switch
Indication
Isolation
Off: Ports can transmit data with each other.
On: The isolated ports cannot transmit data with other downlink ports. They can
transmit data only with the uplink ports.
Off: (default) The switch will not try to monitor or address loop-related issues.
Loop Prevention
(For MS116GS/MS124GS)
On: The switch will monitor and address loop-related issues within the network
structure to prevent disruptions caused by redundant pathing.
Extend
(For MS118CP/MS120GP/
MS126CP/MS128GP)
Off: For MS118CP and MS126CP, the corresponding ports run at 10/100 Mbps;
for MS120GP and MS128GP, the corresponding ports run at 10/100/1000 Mbps.
They only support PoE power supply up to 100 m away.
On: The corresponding ports run at 10 Mbps and support PoE power supply up
to 250 m away.
Priority
(Only for MS118CP)
Off: All the ports transmit data with the same priority.
On: The specific ports transmit data with a higher priority than other ports.
Off: The PoE Auto Recovery function is disabled.
Recovery
(For MS118CP/MS120GP/
MS126CP/MS128GP)
On: The switch will constantly detect the working status of a PoE powered device
(PD). When the switch finds that the PD works abnormally, the switch will reboot it.
Note:
1. The numbers indicate the ports where the feature takes effect. For example, when Extend
1-8 is toggled to On, the Extend mode will be enabled for ports 1-8.
2. By default, ports 1-4 of MS120GP/1-8 of MS126CP/1-4 of MS128GP have higher priority
than other ports in transmitting data if network congestion occurs. It is recommended to
connect key network devices (network cameras, APs, etc.) to these ports.
