• For a combination port, the LEDs of the shared RJ-45 port light to

respond to SFP+ port traffic.

OOB (if present)—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

RPS—(Green) Lights steady when the switch is ready and applicable for

power backup through the Cisco Redundant Power System 2300

(RPS2300), blinking when the power backing up is in process. If the LED

flashes Amber, the Cisco RPS2300 is used for other switch.

Fan—(Green) Lights steady when the cooling fan is operational. Flashes

Amber when both two fans have failures.

Master—(Green) Lights steady when the switch is a stack master.

System—(Green) Lights steady when the switch is powered on, and

flashes when booting, performing self-tests, or acquiring an IP address. If

the LED flashes Amber, the switch has detected a hardware failure, a

firmware failure, and/or a configuration file error.

Stack ID—(Green) Lights steady when the switch is stacked and the

corresponding number indicates its Stack ID. When a switch has a Stack ID

greater than 4, a combination of the LEDs will light up to add up to the

Stack ID. For example, Stack ID #5 is LED#1 and LED#4, Stack ID #8 will

show LED#1, LED#3 and LED#4.

LINK/ACT—(Green) Located on the left of each port. The light is steady

when a link between the corresponding port and another device is

detected. Flashes when the port is passing traffic.

XG—(Green) Located on the right of a 10G port. 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 a Gigabit port or the OOB 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 10G port. Lights

steady when a connection is made through the shared port. Flashes when

the port is passing traffic.
