1.If one power-supply module is installed but not turned on, the module LEDs continue to operate because of the shared voltage between the power-supply modules. If the only operating power-supply module fails or is turned off, the LEDs for neither module are on.

For more information about replacing a power-supply module, wiring a DC power-supply module, and for module specifications, see Chapter 3, “Power Supply and Fan Module Installation,” and Appendix A, “Technical Specifications.”

Fan Modules

The 24- and 48-port switch models have one internal hot-swappable 12-V fan module that inserts in the switch rear panel (part number C3K-BLWR-60CFM=).

The Catalyst 3560E-12D switch has four internal hot-swappable 12-V fan modules that insert in the switch rear panel. The Catalyst 3560E-12SD switch has two internal hot-swappable 12-V fan modules that insert in the switch rear panel. Each fan module (part number C3K-FAN-16CFM=) has a green LED that shows that it is operating. The LED is off when there is a fan failure.

The Catalyst 3560E-12D or 3560E-12SD switch continues to operate when there is one failed fan, either a power-supply fan or a chassis cooling fan. If one fan fails, the switch returns an error message. If a second fan fails, either a power supply fan or a chassis cooling fan, the switch returns an error message, writes a failure log to flash memory, and shuts down.

For more information about installing a fan module and the module specifications, see Chapter 3, “Power Supply and Fan Module Installation,” and Appendix A, “Technical Specifications.”

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.
