• 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.
OOB Port (if present)—The Out of Band (OOB) port is a CPU's Ethernet
port that can be used only as a management interface. Bridging between
the OOB port and the in-band Layer 2 interface is not supported.
Front Panel LEDs
PoE (if present)—(Amber) Located on the right of the port. The LED lights
steady when power is being supplied to a device attached to the
corresponding port.
Master—(Green) The LED lights steady when the switch is a stack master.
System—(Green) The LED lights steady when the switch is powered on,
and flashes when booting, performing self-tests, or acquiring an IP

when a link between the corresponding port and another device is
detected, and flashes when the port is passing traffic.
XG—(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.
Gigabit—(Green) Located on the right of the OOB 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.
SFP+ (if present)—(Green) Located on the right of a 10G port. The LED
lights steady when a connection is made through the shared port, and
