Cisco Cisco SG200-26P 26-port Gigabit PoE Smart Switch ユーザーガイド

System LED—(Green) Lights steady when the switch is powered on, and 
flashes when booting, performing self tests, and acquiring an IP address. If 
the LED flashes amber, the switch has detected a hardware failure.

LINK/ACT LED—(Green) Located on the left of the port. Lights steady 
when a link between the corresponding port and another device is 
detected. Flashes when the port is passing traffic. 

The System and LINK/ACT LEDs are on each model of the switch. 

The following LEDs are only present on switch models that have those 
capabilities:

PoE (if present)—(Amber) Located on the right of the port. Lights steady to 
indicate that power is being supplied to a device attached to the 
corresponding port.

100M LED (if present)—(Green) Located on the right of the port. Lights 
steady when another device is connected to the port, is powered on, and a 
100 Mbps link is established between the devices. When the LED is off, the 
connection speed is under 100 Mbps or nothing is cabled to the port.

Gigabit LED (if present)—(Green) Located on the right of the port. Lights 
steady when another device is connected to the port, is powered on, and a 
1000 Mbps link is established between the devices. When the LED is off, 
the connection speed is under 1000 Mbps or nothing is cabled to the port.

SFP (if present)—(Green) Located on the right of a GE port. Lights steady 
when a connection is made through the shared port. Flashes when the port 
is passing traffic.

The switch might also have a reset button. The switch can be reset by 
inserting a pin or paper clip into the reset opening. See
