Chapter 3 Power Supply and Fan Module Installation

Installing a DC-Power Supply

For Catalyst 3560E-12D and 3560E-12SD switches, align the captive screw with the screw hole. Using a ratcheting torque screwdriver, torque the screw to 4 lbf-in. (64 ozf-in.)

Step 8 (Optional) Assemble the AC power cord retainer with the large end of the plastic bushing facing away from the switch. Position the assembly on the power cord, and insert the wire bales into the slots on the switch rear panel (Figure 3-3).

Step 9 Connect the power cord to the power supply and to an AC-power outlet. Turn on the power at the power source. For Catalyst 3560E-12D and 3560E-12SD switches, also turn on the power supply on/off switch.

Step 10 For 24- and 48-port switches, confirm that the power supply AC OK LED is green. See Table 1-12for a description of the module LEDs.

For Catalyst 3560E-12D and 3560E-12SD switches, confirm that the power supply Input OK LED is green. See Table 1-14for a description of the power supply LEDs.

Installing a DC-Power Supply

To connect the switch to a DC-input power source, follow these steps:

1.Preparing for Installation, page 3-5

2.Grounding the Switch, page 3-5

3.Installing the DC Power Supply in the Switch, page 3-8

4.Wiring the DC-Input Power Source, page 3-9

Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the terminal block plug. Statement 122

Warning Before connecting or disconnecting ground or power wires to the chassis, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. Use a voltmeter to test for 0 (zero) voltage at the power terminals on the chassis. Statement 196

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.
