Yellow on: Running at 100/10 Mbps but no activity.
Yellow Flashing: Running at 100/10 Mbps and is transmitting or receiving data.
Off: No device is linked to the corresponding port.
Note:
The SFP ports only support 1000 Mbps SFP module connection, and they only have Green
On/Green Flashing/Off LED indications.
On: The port is connecting and supplying power to a PD.
PoE Status
(For MS118CP/
MS120GP/
Flashing: The PoE power circuit may be in short or the power current may be overloaded
or non-standard PD is connected or the amount of power of the port has exceeded the
power limit.
MS126CP/
MS128GP)
Off: No PD is connected to the corresponding port or no power is supplied according to
the power limits of the port.
On: The remaining PoE power is ≤ 7 W.
PoE Max
(For MS118CP/
MS120GP/
Flashing: The remaining PoE power keeps ≤ 7 W after this LED is on for 2 minutes.
MS126CP/
Off: The remaining PoE power is > 7 W.
MS128GP)
10/100/1000Mbps RJ45 Port
Designed to connect to the device with a bandwidth of 10 Mbps, 100 Mbps or 1000 Mbps. The PoE
ports (ports 1–16 of MS120GP/ports 1–24 of MS128GP) can provide power for PDs.
10/100Mbps RJ45 Port
Designed to connect to the device with a bandwidth of 10 Mbps or 100 Mbps. The PoE ports (ports 1–16
of MS118CP/ports 1–24 of MS126CP) can provide power for PDs.
SFP Port
Designed to install the SFP module. MS118CP/MS120GP/MS126CP/MS128GP has 2 SFP ports which
support 1000 Mbps SFP module connection. On MS118CP and MS126CP, an SFP Port and the
associated 10/100/1000 Mbps RJ45 Port are called a “Combo” port, which means they cannot be
used simultaneously.
