Chapter 2 Switch Installation

Installing SFP Modules

Installing an SFP Module

When installing SFP modules, observe these general precautions:

•Do not remove the dust plugs from the SFP modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

•Removing and installing an SFP module can shorten its useful life. Do not remove and insert any SFP module more often than is absolutely necessary.

•To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices.

To install an SFP module, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

Caution To avoid damage to the converter module, first install the converter module in the switch 10-Gigabit Ethernet slot before installing the SFP modules.

Step 2 For switches without SFP module slots, install a converter module in the 10-Gigabit Ethernet module slot as described in the “Installing X2 Transceiver Modules and Converter Modules” section on page 2-20.

Step 3 Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.

On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection, either send or receive (TX or RX).

Step 4 If the SFP module has a bale-clasp latch, move it to the open, unlocked position.

Step 5 For 24- and 48-port switches, position the SFP module face up to install in the upper converter module slot (slot 1). Position the module face down to install in the lower converter module slot (slot 2). See Figure 2-22.

For Catalyst 3560E-12D switches, position the SFP module top facing right to install in a converter module slot. See Figure 2-23.

For Catalyst 3560E-12SD switches, position the SFP module face up to install it in a module slot. See Figure 2-24. For an example of installing SFPs in a converter module, see Figure 2-22.

Step 6 If the module has a bale-clasp latch, close it to lock the SFP module in place.

Step 7 Remove the SFP dust plugs and save.

Step 8 Connect the SFP cables.

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.
