Front Panel Description Chapter 1 Product Overview Table 1-6 Port Mode PoE Meaning of Port LED Colors in Different Modes on the Switch LED Color Off Meaning PoE is off. Green Alternating green and amber Blinking amber If the powered device is receiving power from an AC power source, the PoE port LED is off even if the powered device is connected to the switch port. PoE is on. The port LED is green only when the switch port is providing power. PoE is denied because providing power to the powered device will exceed the 370 W switch power capacity. PoE is off due to a fault. STAT (port status) DUPLX (duplex) SPEED Caution PoE faults are caused when noncompliant cabling or powered devices are connected to a PoE port. Only standard-compliant cabling can be used to connect Cisco prestandard IP Phones or wireless access points or IEEE 802.3af-compliant devices to PoE ports. You must remove from the network the cable or device that causes a PoE fault. Amber PoE for the port has been disabled. By default, PoE is enabled. Off No link, or port was administratively shut down. Green Link present. Blinking green Activity. Port is sending or receiving data. Alternating green-amber Link fault. Error frames can affect connectivity, and errors such as excessive collisions, cyclic redundancy check (CRC) errors, and alignment and jabber errors are monitored for a link-fault indication. Amber Port is blocked by Spanning Tree Protocol (STP) and is not forwarding data. Note After a port is reconfigured, the port LED can remain amber for up to 30 seconds as STP checks the network topology for possible loops. Blinking amber Port is blocked by STP and is not sending or receiving packets. Off Port is operating in half duplex. Green Port is operating in full duplex. 10/100 and 10/100/1000 ports Off Port is operating at 10 Mb/s. Green Port is operating at 100 Mb/s. Blinking green Port is operating at 1000 Mb/s. SFP ports Off Port is operating at 10 Mb/s. Green Port is operating at 100 Mb/s. Blinking green Port is operating at 1000 Mb/s. Note When installed in Catalyst 3560 switches, 1000BASE-T SFP modules can operate at 10, 100, or 1000 Mb/s in full-duplex mode or at 10 or 100 Mb/s in half-duplex mode. 1-14 Catalyst 3560 Switch Hardware Installation Guide OL-6337-07

Meaning of Port LED Colors in Different Modes on the Switch
Port Mode
LED Color
Meaning
PoE
Off
PoE is off.
If the powered device is receiving power from an AC power source, the PoE port LED
is off even if the powered device is connected to the switch port.
Green
PoE is on. The port LED is green only when the switch port is providing power.
Alternating green
and amber
PoE is denied because providing power to the powered device will exceed the 370 W
switch power capacity.
Blinking amber
PoE is off due to a fault.
Caution
PoE faults are caused when noncompliant cabling or powered devices are
connected to a PoE port. Only standard-compliant cabling can be used to
connect Cisco prestandard IP Phones or wireless access points or
IEEE 802.3af-compliant devices to PoE ports. You must remove from the
network the cable or device that causes a PoE fault.
Amber
PoE for the port has been disabled. By default, PoE is enabled.
STAT
(port status)
Off
No link, or port was administratively shut down.
Green
Link present.
Blinking green
Activity. Port is sending or receiving data.
Alternating
green-amber
Link fault. Error frames can affect connectivity, and errors such as excessive
collisions, cyclic redundancy check (CRC) errors, and alignment and jabber errors
are monitored for a link-fault indication.
Amber
Port is blocked by Spanning Tree Protocol (STP) and is not forwarding data.
Note
After a port is reconfigured, the port LED can remain amber for up to
30 seconds as STP checks the network topology for possible loops.
Blinking amber
Port is blocked by STP and is not sending or receiving packets.
