Chapter 2 Switch Installation

Installing the Switch

One cable guide and one black Phillips machine screw for attaching the cable guide to one of the mounting brackets

One RPS connector cover (for wall mounting)

Two Phillips pan-head screws (for attaching the RPS cover)

Four Phillips truss-head screws (for wall-mounting brackets)

One DC terminal block plug (also called a terminal block header; only Catalyst 3550-24-DC switches)

Rack-Mounting

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006

To install the switch in a 19-inch or 24-inch rack (24-inch racks require optional mounting hardware), follow the instructions described in these procedures:

Attaching Brackets to the Catalyst 3550-12T and 3550-12G Switches, page 2-6

Attaching Brackets to the Catalyst 3550-24,3550-24-DC,3550-24-FX,3550-24PWR, and 3550-48 Switches, page 2-8

Mounting the Switch in a Rack, page 2-12

Note Installing the switch in a 24-inch rack requires an optional bracket kit not included with the switch. You can order a kit containing the 24-inch rack-mounting brackets and hardware from Cisco. For the Catalyst 3550-12T and 3550-12G switches, order part number RCKMNT-3550-1.5RU=. For the Catalyst 3550-24, 3550-24-DC, 3550-24-FX, 3550-24PWR, and 3550-48 switches, order part number RCKMNT-1RU=.

3550 specifications

Cisco Systems 3550 is a series of enterprise-class multilayer switches that have gained popularity in both enterprise and service provider networks. Introduced in the early 2000s, the 3550 series was designed to meet the increasing demand for advanced networking capabilities, including Layer 2 and Layer 3 switching, making it suitable for various network environments.

A standout feature of the Cisco 3550 is its support for advanced Layer 3 switching capabilities. This means it can perform routing functions similar to traditional routers while maintaining the speed and efficiency of a switch. The 3550 facilitates IP routing, enabling enhanced communication among different subnets without the need for additional routing devices.

The Cisco 3550 series is equipped with a range of ports, typically providing up to 48 Ethernet 10/100 ports and optional Gigabit Ethernet ports, ensuring scalability and flexibility in various network designs. The switches support Power over Ethernet (PoE), allowing the delivery of electrical power through Ethernet cables to connected devices, such as IP phones and wireless access points, streamlining installations and reducing cable management complexity.

Quality of Service (QoS) is another essential feature of the Cisco 3550. The switch supports advanced QoS mechanisms, which provide the ability to prioritize traffic. This is crucial in environments where bandwidth is limited, as it ensures that time-sensitive applications, like VoIP and video conferencing, receive sufficient bandwidth to function optimally.

In terms of security, the Cisco 3550 includes features such as access control lists (ACLs), port security, and VLANs (Virtual Local Area Networks). These features help in segmenting network traffic and preventing unauthorized access to sensitive information, thereby enhancing network security.

The Cisco 3550 is highly regarded for its robustness and reliability, making it a suitable choice for various organizations looking to maintain high availability in their networking environments. Its management capabilities include support for Cisco's IOS software, which offers a command-line interface for configuration, as well as options for SNMP and web-based management tools.

Overall, the Cisco Systems 3550 series is well-regarded for its multilayer switching capabilities, comprehensive feature set, and versatility in meeting the diverse needs of modern networking, making it a favored solution for businesses aiming to build efficient and secure network infrastructures.
