SFP Port (if present)—The small form-factor pluggable (SFP) ports are

connection points for modules, so the switch can link to other switches.

These ports are also commonly referred to as miniGigaBit Interface

Converter (miniGBIC) ports. The term SFP is used in this guide.

SFP+ Port (if present)—The small form-factor pluggable plus (SFP+) are

connection points for modules so that the switch can link to other switches.

These ports are also commonly referred to as mini 10GigaBit Interface

Converter ports. The term SFP+ is used in this guide.

Some SFP interfaces are shared with one other RJ-45 port, called a

combo port. When the SFP is active, the adjacent RJ-45 port is disabled.

The LEDs of the corresponding RJ-45 port flash green to respond to the

SFP interface traffic.

LEDs

System LED—(Green) The LED 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. The LED lights

steady when a link between the corresponding port and another device is

detected, and flashes when the port is passing traffic.

100M LED (if present)—(Green) Located on the right of the port. The LED

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. The LED

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.

XG LED (if present)—(Green) Located on the right of a 10G port. The LED

lights steady when another device is connected to the port, is powered on,

and a 10 Gbps link is established between the devices. When the LED is

off, the connection speed is under 10 Gbps or nothing is cabled to the port.

PoE (if present)—(Amber) Located on the right of the port. The LED lights

steady to indicate that power is being supplied to a device attached to the

corresponding port.
