The network switch is one of the most common devices used and implemented with any company’s networking infrastructure. Therefore, the selection of switches or upgrading is a crucial part of the most network design projects.
Network switch components mainly include
- Switch Chassis
- Supervisor Engine
- Switching Modules
- IOS/CatOS software and
- Power Supplies.
The decision to purchase new switches or upgrade the existing ones is determined after considering the complete network assessment and structural design features specified. Wireless designs, for instance, contain network switches interfacing directly with access points. All these have a powerful affect on the switch in terms of-
- Increased utilization
- Assigned switch ports
- Access control lists
- Spanning Tree Protocol and
- Increased wattage draw from Power over Ethernet (PoE).
The selection process of 8 Port PoE Switch and 4 Port PoE Switch as follows:
The following pointers clearly describe the 5 main components of any network switch selection process:
- Consider the network assessment and design features specified
- Select switches that include all the design features
- Select switches with proper scalability
- Balance cost and equipment features while meeting budget guidelines
- Select IOS and/or CatOS software version
Some typical switch features to consider:
- Are there enough Chassis slots?
- What Supervisor Engines are supported?
- Does the Engine support failover?
- Is Multi Layer Switching available?
- What Switching Modules are available?
- What Uplinks are available?
- What Power Supply wattage is available?
- How many Rack Units are needed?
The industrial design of the 8 Port PoE Switch, and all internal constituents, simply make it ideal for utilization under harsh environments including vibrations, extreme temperature fluctuations and shocks like:
- Industrial & factory automation
- Marine & mining
- Rail & ITS
- Oil & Gas
- Outdoor applications
These network switches can very easily be implemented with IOS, IOS and CatOS or any special CatOS software. Some high quality networking equipment also deploy the Supervisor Engine IV without any MSFC onboard. The Route Processor is very systematically integrated with the engine. With that kind of design, the Engine IV never supports CatOS.
- Native IOS – deployed at the edge of the network where most routing takes place and some switching is required.
- Hybrid – deployed at the core of the network where there is both high speed switching and routing.
- CatOS – deployed at the network access layer where there is switching and no routing
features determine what kind of mode and IOS or CatOS version is chosen. The
programme running on the Route Processor should definitely be IOS while the
Engine Switch Processor is bound to run IOS (native mode) or CatOS (hybrid
