Catalyst 3560E-12D and 3560E-12SD Switch Power-Supply Modules

The Catalyst 3560E-12D and 3560E-12SD switches have two internal 300-W power-supply modules (Table 1-13). The AC-power-supply modules are autoranging units that support input voltages between 85 and 265 VAC. The DC-power-supply modules have a single input feed and support input voltages between –40.5 and –72 VDC. You can use two AC modules, two DC modules, or a mixed configuration of one AC and one DC power-supply module.

The Catalyst 3560E-12D and 3560E-12SD switches can operate with only one active power-supply module. However, two power supply modules must always be physically installed in the switch rear panel when the switch is operating, even if one module is defective. This is required to maintain adequate airflow in the chassis and prevent overheating.

Caution Do not operate a Catalyst 3560E-12D or 3560E-12SD switch with one power-supply module removed from the rear panel. For proper chassis cooling, two power-supply modules must be installed in the switch rear panel.

The AC power-supply modules have a power cord for connection to an AC-power outlet. The DC power-supply modules require wiring to a DC-power source. The AC-power supplies have an on/off power switch. DC-power supplies do not have an on/off switch.

Cisco Systems 3560-E, 3750-E manual AC-Power-Supply Module LEDs, DC-Power-Supply Module LEDs Description

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.
