Managed Network Switches 101

TRENDnet Managed Network Switches 101 Whitepaper

A network switch’s basic function is to connect devices together on your computer network. Network switches are available with varying amounts of ports and features to meet the needs and demands of your working project.

Switches are already “smart” devices; after receiving data, the switch sends that data to a specific device on the network (and not a blanket transmission to all connected devices). This is particularly useful as the switch is able to receive data from all connected devices and transmit that data to specific devices simultaneously.

Managed vs Unmanaged Switches

There are two types of switches: unmanaged and managed. Amongst those, managed switches are further broken down by varying sub-categories. Simply put, managed switches feature network controls that allow you to customize, manage, and monitor your network. Conversely, unmanaged switches are “plug and play” solutions, designed only to increase port density and cannot be further configured.

TRENDnet offers both unmanaged and managed switches (Layer 2/Layer2+ and Web Smart). Today, not much differs between Layer 2 and Web Smart switches; both Layer 2 switches and Web Smart switches feature a graphical user interface (GUI), however, only Layer 2 switches offer a command line interface (CLI).

The CLI and GUI each have their own advantages and disadvantages. However, a command line interface is generally viewed as more efficient, allows for more control over the system, and is easier to use for remote access. However, it is designed for more advanced network administrators.

TRENDnet Network Switches: Managed vs Unmanaged

Important Managed Switch Features

SNMP

Simple Network Management Protocol is for monitoring the status and management of devices connected to the network.

VLAN

Virtual LAN configurations group devices together to isolate traffic, improve network performance, add an extra layer of security, and reduce unnecessary network traffic.

QoS

Quality of Service allows you to prioritize your network traffic and improve performance (commonly used in VoIP and video applications).

RSTP/STP

Rapid Spanning Tree Protocol and Spanning Tree Protocol are used for redundancy in the network and to prevent looping. RTSP recovers the network from a failed link and locates a new network path in significantly less time than STP.

Port Mirroring

Port mirroring helps to identify and troubleshoot network problems by mirroring data traffic to a designated port on the switch.

IGMP Snooping

IGMP snooping eliminates network congestion caused by multicast traffic. IGMP snooping ensures that multicast data is only forwarded to specific devices that exclusively request the multicast data rather than sending that data to all the devices connected to the network (commonly used in IPTV applications).

How to choose the best switch for your network

How to choose the best switch for your network

Choosing the best switch for your network or project can be a daunting task. Review this basic step-by-step guide on how to choose the best switch for your networking project. This guide will review class types, port requirements, form factors, and basic managed switch features.

Step 1: Choose the class and speed

TRENDnet Network switches and levels of management
Class
There are several types of switches, each providing different levels of management. Unmanaged switches allow you to expand your network easily with no special configuration or specialized networking knowledge. Unmanaged switches simply increase the number of ports (or available connections) to your network by increasing port density.

Web smart and layer 2 managed switches have additional features such as VLAN support, PoE controls, traffic analysis, and multicast support. EdgeSmart switches are basic web smart switches that offer only the most commonly used management features to help reduce both cost and setup complexity.

There are many different levels of managed switches (and not all are discussed here, such as Layer 3 switches); the type of switch you need and the best switch for your network will depend on the features required for your project. (See TRENDnet Managed Switches 101 Whitepaper for more info on managed switches).

Speed
Required bandwidth will determine whether you need a 10G, 2.5G, Gigabit, or 10/100 switch. Fast Ethernet or 10/100 switches are more cost-effective, but Multi-Gigabit and Gigabit switches can provide better scalability. Choose a speed that is enough for your current project, but plan for the future and consider extra bandwidth.

Specialized Switches
Look for specialized switches, such as industrial switches or AV switches, to meet the unique needs of your custom networking project(s).

Step 2: Choose port count

Determine how many devices that need to be connected in order to identify the number of ports you’ll need. For your surveillance solutions, we recommend reserving 2 additional ports for your NVR and/or network bridge/client.

Step 3: Choose form factor

The form factor that you choose will come down to both your own personal preference and the switch’s application. Desktop and wall-mountable switches are great when you want to save space; they are generally more affordable and are quieter since most desktop and wall-mount switches do not have internal fans. Rackmount switches are ideal when you want to integrate it into a new or existing server room or rack. DIN-rail switches are usually reserved for industrial applications.

Plastic or metal?

Having trouble deciding which type of housing is best for you? Metal switches are more durable, but plastic switches are a cost-effective solution.

Step 4: Review the features

Knowing the class of the switch chosen in step one helps us identify the possible feature set of that switch. However, regardless of class, switches can have varying features, and the features you want will depend on your project’s needs. Review the switch features to make sure you choose the best switch for your network.

Unmanaged switches have no management features. Managed switches include a variety of features for traffic management, troubleshooting, access controls, and monitoring. Some common features include LACP, VLAN, QoS, IGMP snooping, and bandwidth control per port. Once you’ve chosen your switch, double-check that it offers the features you need, as switches can have differing feature sets even within the same class.

Product Review: TRENDnet Industrial Network Switch

The TRENDnet TI-PG1284i network switch is an attractive solution for locations that are less than ideal.

TRENDnet has introduced a new industrial-grade hardened network switch that promises to become a “go-to” component for installers when they have network locations that don’t have the best environmental conditions.

TRENDnet has been involved in the electronics world since 1990 and was founded in Torrance, Calif. The company has been building network solutions for the consumer, commercial and industrial markets, and today supplies many different solutions for its markets.

Today’s electronic networks whether they are designed and utilized for CCTV, access control, voice over Internet or some other network function, rely on several key components to complete their system designs.

Increasingly the network switch is installed in locations that can best be described as “less than friendly” to electronics. This review covers a switch that is designed to roll with the punches.

TRENDnet TI-PG1284i

Construction

The TI-PG1284i network switch is constructed with a hardened metal casing and about the size of a hardback novel. The unit has a solid feel to it, shows good construction and has an IP30-rated enclosure that protects the internal components from external dirt and dust intrusion.

The unit is not immune to liquids so mounting it exposed outdoors is out of the question! The switch is designed for harsh environments and can withstand temperatures from -40° to 75° C / -40° to 167° F.

The switch has 12 network ports and one RS-232 port on the front panel. Of those 12 network ports eight are gigabit RJ-45 connections and four are GB SFP ports. The top of the unit has connections for the external power supplies (both primary and redundant) and the external alarm.

There are also addressable DIP switches that allow the end user to customize the notification alarms from the switch for every port and power connection. There is also a grounding terminal on the top of the case to provide greater protection from static shocks.

The TI-PG1284i relies on an external power source of 48VDC; the input voltage has a range of 48 to 57VDC with a rating of 240+ watts. This voltage can be supplied from a master power source or from a standalone unit.

For our testing, we were provided a complementary component power supply, Model TI-S24048, to provide the required input voltage. This unit, just like the switch, is designed to mount to a DIN rail to provide a secured installation.

The electrical wiring for the power unit connects to a Phoenix connector that allows the unit to be easily disconnected from its 120VAC power source should servicing be required.

Features

The TI-PG1284i can supply up to 30W of PoE/PoE+ power for its network ports. The power to each of these ports can be turned on and off via the web-based graphical user interface; this allows the user to remotely reset a device, which can be very effective for troubleshooting or refreshing field devices.

The inclusion of four SFP ports allows the switch to be connected to different devices via fiber-optic connections. This can allow the switch to be used as a hub or repeater for a fiber network; this can be very handy when there are different connection requirements for a network’s construction.

The inclusion of alarm outputs for each network port (as well as the power supply) provides an alert to the user that there is a system problem that requires immediate attention.

The switch is constructed to resist shock and vibration damage and has been rated for durability by the International Electrotechnical Commission (IEC). It also has a freefall rating which is one I have a hard time understanding since the unit is designed to be firmly mounted to a DIN rail!

The TI-PG1284i is also rated by the IEC to resist electrostatic discharges and electromagnetic interference. This makes the unit a perfect fit for installation in a congested environment where there might be heavy electrical interferences.

TRENDnet Industrial Switch TI-PG1284i

Setup and Testing

Upon unpacking the contents from the box, I found the unit is supplied with a six-foot RJ-45 to RS-232 cable, a quick installation guide, and a CD containing the full product manual and the quick reference guide.

For my examination and testing I performed a basic installation utilizing the switch, power supply, computer and PoE network camera. I used a fixed dome IP camera to test the PoE port switching that allowed me to switch the camera on and off as needed.

As noted, having the ability to reset a device remotely is a wonderful thing — think of the time and effort that can be saved by being able to remote in to the switch and perform this reset.

Compare this to grabbing your eight-foot ladder, slugging it through a back hallway and climbing up to a field node just to unplug a camera or other network device. This feature is worth its weight in gold to me.

The embedded GUI of the TI-PG1284i allows for many system settings within the network. While my networking experience is fairly extensive and has been put to the test many times, I must confess that I was not completely familiar with all of the arcane system settings of which this device is capable, according to the manual.

In addition to the web-based GUI for programming and control of the TI-PG1284i, the unit can be controlled via RS-232 commands from your computer for those “old-school” system administrators.

While I am not one who is well versed in command line interface (CLI) commands, I understand its usefulness for network professionals. Again, this switch provides the user with a plethora of options and protections.

Conclusions

The TI-PG1284i is a robust switch that will perform well in any system’s network. Its size, design and durability makes it a great unit for installation in varied environments, from a small field node in a hazardous location to a network closet with many switches configured together. The TI-PFG1284i will make a welcome addition to any installer’s repertoire.
