Chapter 3 Power Supply and Fan Module Installation

Installing an AC-Power Supply

Installing an AC-Power Supply

To remove and install an AC-powered power-supply module, follow these steps:

Step 1 Turn off the power at its source. For Catalyst 3560E-12D and 3560E-12SD switches, also turn off the power supply on/off switch.

Step 2 If used, detach the power cord retainer assembly from the power cord.

Step 3 Remove the power cord from the power connector.

Step 4 For 24- and 48-port switches, use a Phillips screwdriver to loosen the two captive screws at the lower edge that secure the power supply to the switch chassis (Figure 3-1).

For Catalyst 3560E-12D and 3560E-12SD switches, use a Phillips screwdriver to loosen the captive screw at the left edge of the power supply (Figure 3-2).

Caution Do not leave the power-supply slot open for more than 90 seconds while the switch is operating.

Step 5 Remove the power-supply module from the power slot by pulling on the extraction handle.

Step 6 Insert the new power supply into the power-supply slot, and gently push it into the slot (Figure 3-1and Figure 3-2). When correctly inserted, the power supply is flush with the switch rear panel. The 1150-W power-supply module extends 3.6 inches (9.14 cm) from the switch rear panel.

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.
