Chapter 4 Removing and Replacing FRUs

Replacing Backplane Modules

Verifying the Installation

Note To check the operation of the fans, you need to power up the chassis.

Follow these steps to verify that the new fan assembly was installed correctly:

Step 1 Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure that the fan assembly is inserted completely in the chassis and that the faceplate is flush with the switch back panel.

Step 2 The fan tray LED should light and be green.

Step 3 If after several attempts the fans do not operate, or if you experience trouble with the installation (for instance, if the captive installation screws do not align with the chassis holes), contact the Cisco TAC for assistance.

Replacing Backplane Modules

There are 5 redundancy modules (also called mux buffers) and 1 clock module on a Catalyst 4507R-E chassis backplane. A Catalyst 4510R-E has 8 redundancy modules on its backplane. They are accessible from the front if the switching modules and supervisor engines are removed. There are two types of redundancy modules, and they are interchangeable.

The clock module replacement procedure is identical to the redundancy module replacement procedure, the connectors are the same. These modules are not hot-swappable, the switch must be taken out of service to replace them.

To replace the backplane modules:

Step 1 Make sure you are grounded with an ESD strap.

Step 2 Turn off the power to the chassis.

Step 3 Remove all supervisor engines and switching modules from the chassis, and find the backplane modules you need to replace.

Note Keep a record of switching module and their slots, so that you can put them back correctly.

Note Generic switching module replacement procedures are documented at: http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/hardware/configuration/notes/gM dCf_nt.html

Figure 4-18shows the front view of the backplane with supervisors and switching modules removed.

4500 E-Series, WSUPOE12VPSPL specifications

Cisco Systems has long been at the forefront of networking technology, consistently delivering innovative products that shape the future of digital communication. Among its extensive range of offerings, the WSUPOE12VPSPL and the Catalyst 4500 E-Series stand out as exemplary solutions tailored for businesses seeking robust, scalable, and versatile network infrastructure.

The WSUPOE12VPSPL is a 12-port Power over Ethernet (PoE) switch that provides significant advantages for organizations looking to streamline their operations. It is designed to deliver power and data over a single cable, reducing the clutter of additional power supplies and cords. This efficiency not only simplifies deployment but also enhances the flexibility to place devices anywhere within the network environment, making it an ideal choice for powering IP phones, wireless access points, and surveillance cameras.

Main features of the WSUPOE12VPSPL include its ability to deliver up to 15.4 watts of power per port, supporting up to 12 PoE devices simultaneously. This capability is especially beneficial in environments where power outlets are scarce or where devices are located in non-traditional locations. With a rugged design suitable for various operational contexts, it ensures reliable performance even under demanding conditions.

When integrated within the Catalyst 4500 E-Series switches, organizations can leverage advanced technologies that enhance overall network performance and security. The Catalyst 4500 E-Series is known for its modularity, allowing businesses to expand their networks as required. Its architecture supports high throughput, advanced QoS features, and extensive Layer 2 and Layer 3 capabilities, ensuring efficient data handling and management.

Moreover, the Catalyst 4500 E-Series can integrate with Cisco’s digital network architecture and software-defined networking (SDN), facilitating automation and better visibility through tools such as Cisco DNA Center. This allows IT administrators to efficiently manage network resources, monitor performance, and implement security policies with ease.

In terms of operational intelligence, the integration with analytics tools enables organizations to gain insights into traffic patterns, user behaviors, and application performance, thus empowering data-driven decision-making.

Overall, the Cisco WSUPOE12VPSPL and the Catalyst 4500 E-Series offer a powerful combination of features, technologies, and characteristics that make them indispensable to modern networking. They cater to the demands of diverse business environments, ensuring reliability, flexibility, and scalability as organizations continue to evolve in an increasingly digital landscape.
