Power Supply Module Installation | Cisco Systems 3750-E, RPS 2300

Power Supply Module Installation

This section describes how to remove and install a new or replacement power supply module in Catalyst 3750-E and Catalyst 3560-E switches, or an RPS 2300. See these sections:

•Tools and Equipment, page 5

•Installation Guidelines, page 5

•Installing an AC-Power Supply, page 6

•Installing a DC-Power Supply (Only Catalyst 3750-E and 3560-E Switches), page 8

Tools and Equipment

Obtain these necessary tools and equipment:

•Ratcheting torque screwdriver with a number-2 Phillips head that exerts up to 15 pound-force inches (lbf-in.) or 240 ounce-force inches (ozf-in.) of pressure. For 1150-W power supply modules, the screwdriver shaft length should be at least 6-inches long.

•Power-supply power-cord retainer in the switch accessory kit.

Installation Guidelines

Observe these guidelines when removing or installing a power supply module:

•Do not force the power supply module into the slot. This can damage the pins on the switch or the RPS 2300 if they are not aligned with the unit.

•A power supply module that is only partially connected to the switch or the RPS 2300 can disrupt the system operation.

•Remove power from the power supply module before removing or installing the module.

•The switch supports hot swapping of the power supply when the switch is connected to an RPS 2300 that can provide backup power. You can remove and replace the power supply without interrupting normal switch operation. When you insert a new power supply in the switch, there is a 5-second delay while the switch software polls the device. The switch power supply then automatically provides power, and the RPS is available to power other devices.

•The RPS 2300 supports hot swapping of the power supply module when an external device is connected to it.

–If the RPS 2300 is not backing up an external device, you can remove and replace the power supply module without disconnecting the system power.

–If two 1150-W power supply modules are installed in the RPS 2300, you can remove one of the modules when backing up an external device.

–The RPS 2300 does not support hot swapping of the power supply module when two 750-W power supply modules are installed and the RPS 2300 is backing up a device with an 1150-W power supply.

•Make sure that you tighten the power supply module captive screws before moving the switch or the RPS 2300.

•When replacing the 1150-W or the 750-W power supply module, verify that you are using the correct power cord (CAB-16AWG-AC, only North America).

3750-E, 3560-E, RPS 2300 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.
