The following are the essential features of the switch.

• Conforms to IEEE 802.3, 802.3u, and 802.3x standards.
• Auto-negotiating 10/100Mbps Ethernet RJ-45 ports.

• Auto-negotiating crossover for all 10/100Mbps Ethernet RJ-45 ports.

• IEEE 802.1p supports two priority queues for outgoing traffic.
  Back-Pressure-Base flow control on Half-duplex ports.

• Pause-Frame-Base flow control on Full-duplex ports.
• Store-and-forwarding switching architecture for abnormal packet filtering.
  Supports automatic address learning.
  No-Blocking full wire speed architecture.
  Fan free design.
• Embedded 4K MAC address table providing 4000 MAC addresses entries.
  Power, LNK/ACT and FDX/COL LEDs.
  Standard 19-inch rack-mount design.

1.2.1 IEEE 802.1p Class of Service

The IEEE 802.1p Class of Service (CoS) provides two queues for high and low priority traffic. This improves network efficiency and performance by giving higher priority to outgoing traffic. For example, the lower queue has a priority value in the range of zero to three and the higher queue has a priority value in the range four to seven.

1.4 Ethernet Switching Technology

Ethernet Switching Technology has dramatically boosted the total bandwidth of a network, eliminated congestion problems inherent with CSMA/CD (Carrier Sense multiple access with Collision Detection) protocol, and greatly reduced unnecessary transmissions.

This revolutionized networking in a number of ways:

By allowing two-way, simultaneous transmissions over the same port (Full-duplex), which essentially doubled the bandwidth.

Reducing the collision domain to a single switch-port, which eliminated the need for carrier sensing.

Using the store-and-forward technology's approach of inspecting each packet to intercept corrupt or redundant data, switching eliminated unnecessary transmission that slowed the network.

By employing address learning, which replaced the inefficient receiving port.

Auto-negotiation regulates the speed and duplex of each port, based on the capability of both devices. Flow-control allows transmission from a 100Mbps node to a 10Mbps node without loss of data. Auto-negotiation and flow-control may require disablement for some networking operations involves legacy equipment. Disabling the auto-negotiation is accomplished by fixing the speed or duplex of a port.

Ethernet Switching Technology supplied higher performance at costs lower than other solutions. Wider bandwidth, no congestion, and the reduction in traffic is why switching is replacing expensive routers and inefficient hubs as the ultimate networking solution.

1.5 Applications

This section provides two network topology examples in which the switch is used.

1.5.1 Standalone Workgroup

The switch can be used as a standalone switch to which computers, servers and printer server are directly connected to form a small workgroup.

Figure 1-3 Standalone Workgroup Example

1.5.2 Bridging

With its large address table (4000 MAC address entries) and high performance, the switch is an ideal solution for department networks to connect to the corporate backbone or for connecting network segments.

The following figure depicts a typical segment bridge application of the switch in an enterprise environment. The two workgroups, the standalone server and the two servers can all communicate with each other and share all network resources.

Figure 1-4 Bridging Example

Chapter 2

Hardware Description and Installation

This chapter describes the hardware installation and gives a functional overview of the switch.

2.1 Installation Option

The switch is suitable for an office environment where it can be rack mounted on standard EIA racks or as a standalone.

For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8 cm) at the back of the switch. This is especially important for enclosed rack installations.

2.1.1 Desktop Installation

Step 1. Make sure the switch is clean and dry.
Step 2. Set the switch on a smooth, leveled and sturdy flat space strong enough to support the weight of the switch and the connected cables. Make sure there is a power outlet nearby.
Step 3. Make sure there is enough clearance around the switch to allow air circulation and the attachment of cables and the power cord.
Step 4. Remove the adhesive backing from the supplied rubber feet.
Step 5. Attach the rubber feet to each corner on the bottom of the switch. These rubber feet help protect the switch from shock or vibration and ensure space between devices when stacking.

Figure 2-1 Attaching Rubber Feet

Do not block the ventilation holes. Leave space between switches when stacking.

2.1.2 Rack-Mount Installation

The switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment. Follow the steps below to mount your switch on a standard EIA rack using the included rack-mounting kit.

Step 1. Align one bracket with the holes on one side of the switch and secure it with the bracket screws smaller than the rack-mounting screws. Similarly, attach the other brackets.

Figure 2-2 Attaching Mounting Brackets and Screws

Step 2. After attaching both mounting brackets, position the switch in the rack by lining up the holes in the brackets with the appropriate holes on the rack. Secure the switch to the rack with the rackmounting screws.
