Port Mode

 

Port LED Color

Meaning

 

 

 

 

 

 

PoE2

 

Off

PoE is off.

 

 

 

 

If the device is receiving power from an AC power source, the port

 

 

 

 

LED is off even if the 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

PoE is denied because providing power to the powered device will

 

 

 

green and

exceed the switch power capacity.

 

 

 

amber

 

 

 

 

 

 

 

 

 

 

 

 

Blinking amber

PoE is off due to a fault or because it has exceeded a limit set in the

 

 

 

 

switch software.

 

 

 

 

 

 

 

 

 

 

 

 

Caution PoE faults are caused when noncompliant cabling or

 

 

 

 

 

 

 

powered devices are connected to a PoE port. You can

 

 

 

 

 

 

 

use only standard-compliant cabling to connect Cisco

 

 

 

 

 

 

 

pre-standard IP Phones and wireless access points or

 

 

 

 

 

 

 

IEEE 802.3af-compliant devices to PoE ports. You must

 

 

 

 

 

 

 

remove from the network any cable or device that causes

 

 

 

 

 

 

 

a PoE fault.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Amber

PoE for the port has been disabled.

 

 

 

 

Note PoE is enabled by default.

 

 

 

 

 

 

 

 

 

1.Only Catalyst 3750-E switches.

2.Only switches with PoE ports.

PoE LED

If the PoE LED mode is not selected on a switch with PoE ports, the PoE LED still shows detected PoE problems. Table 1-10lists the PoE LED colors and their meanings.

Table 1-10

PoE Mode LED

 

 

 

Color

 

PoE Status

 

 

 

Off

 

PoE mode is not selected. None of the 10/100/1000 ports have been denied power

 

 

or are in a fault condition.

 

 

 

Green

 

PoE mode is selected, and the port LEDs show the PoE status.

 

 

 

Blinking amber

 

PoE mode is not selected. At least one of the 10/100/1000 ports has been denied

 

 

power, or at least one of the 10/100/1000 ports has a PoE fault.

3750-E, 3560-E specifications

Cisco Systems RPS (Redundant Power System) 2300, along with the 3750-E and 3560-E series switches, represents a significant technological advancement in enterprise networking. These devices are designed to enhance network reliability, scalability, and efficiency, making them integral components in modern enterprise infrastructures.

The Cisco RPS 2300 is designed to provide redundant power to specified Cisco switches, ensuring continuous operation during power disruptions. This system can support up to six devices, enhancing power reliability and reducing downtime. The modularity of the RPS 2300 contributes to its flexibility, allowing enterprises to customize their power solutions to suit their networking needs. It features dual power input, which provides an additional layer of failover capability, ensuring that even in the event of a primary power failure, the backup power system can take over seamlessly.

On the other hand, the Cisco 3750-E series switches are enterprise-class devices that offer a rich feature set to support advanced network functions. These switches come with Cisco’s StackWise technology, enabling users to stack up to nine switches in a single logical unit. This increases port density and simplifies network management. The 3750-E also supports Power over Ethernet (PoE), allowing the delivery of power directly to devices like IP phones and access points through the networking cables. The switch is equipped with high-performance Layer 3 routing capabilities, providing enhanced IP routing options for enterprise networks.

The Cisco 3560-E series switches share many of the advanced features found in the 3750-E models but focus more on providing comprehensive Layer 2 and Layer 3 capabilities in a compact design. The 3560-E series supports Cisco’s advanced security features, such as dynamic VLAN assignment and security group access control lists (ACLs). Additionally, these switches support IPv6, preparing enterprise networks for future growth and addressing requirements.

Both the 3750-E and 3560-E are equipped with energy-efficient technologies, including intelligent power management and support for Energy Efficient Ethernet (EEE), helping organizations reduce their environmental footprint and operating costs. The integration of Cisco’s robust IOS software ensures that these devices are equipped with the latest features, ensuring strong performance, security, and scalability.

In summary, Cisco's RPS 2300, 3750-E, and 3560-E series exemplify the company's commitment to delivering cutting-edge networking solutions that meet the demands of modern enterprises, focusing on reliability, advanced features, and energy efficiency.
