Dimension ES-2024 Ethernet Switch

Chapter 1

Getting

This chapter describes the key features, benefits and applications of the ES-2024.

The ES-2024 is a stand-alone Ethernet switch with 24 10/100Mbps ports, two gigabit (1Gbps or 1000Mbps) ports
and two slots for mini GBIC (Gigabit Interface Converter) transceivers.

With its built-in web configurator, managing and configuring the switch is easy. From cabinet management to port­level control and monitoring, you can visually configure and manage your network via the web browser. Just click
your mouse instead of typing cryptic command strings. In addition, the switch can also be managed via Telnet, the
console port, or third-party SNMP management.

Security

 System management password protection  Port-based VLAN

 IEEE 802.1Q VLAN  802.1x Authentication

Port Link Aggregation

The ES-2024 adheres to the 802.3ad standard for static and dynamic port link aggregation.

Bandwidth Control

 The ES-2024 supports rate limiting in 1Kbps increments allowing you to create different service plans

1-2 Getting to Know the ES-2024

Dimension ES-2024 Ethernet Switch

 The ES-2024 supports IGMP snooping enabling group multicast traffic to be only forwarded to ports that

are members of that group; thus allowing you to significantly reduce multicast traffic passing through your
switch.

 Broadcast storm control

Quality of Service

 Two priority queues so you can ensure mission-critical data gets delivered on time.

 Follows the IEEE 802.1p priority setting standard based on source/destination MAC addresses.

STP (Spanning Tree Protocol) / RSTP (Rapid STP)

(R)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows
a switch to interact with other (R)STP -compliant switches in your network to ensure that only one path exists
between any two stations on the network.

Cluster Management

Cluster management allows you to manage switches through one switch, called the cluster manager.

1.2 Applications

This section shows a few examples of using the ES-2024 in various network environments.

1.2.1 Backbone Application

In this application, the switch is an ideal solution for small networks where rapid growth can be expected in the
near future.

The switch can be used standalone for a group of heavy traffic users. You can connect computers directly to the
switch’s port or connect other switches to the ES-2024.

In this example, all computers connected directly or indirectly to the ES-2024 can share super high-speed
applications on the gigabit server.

To expand the network, simply add more networking devices such as switches, routers, firewalls, print servers etc.

Figure 1-1 Backbone Application

1.2.2 Bridging Example

In this example application the switch is the ideal solution for different company departments to connect to the
corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users
that need high bandwidth can connect to high-speed department servers via the switch. You can provide a super­fast connection by selecting from an array of modules compatible with the ES-2024.

Moreover, the switch eases supervision and maintenance by allowing network managers to centralize multiple
servers at a single location.

Figure 1-2 Bridging Application

Full-duplex mode operation only applies to point-to-point access (for example, when attaching

the switch to a workstation, server, or another switch). When connecting to hubs, use a standard

cascaded connection set at half-duplex operation.

1-4 Getting to Know the ES-2024

Dimension ES-2024 Ethernet Switch

1.2.3 High Performance Switched Workgroup Example

The switch is ideal for connecting two power workgroups that need high bandwidth. In the following example, use
trunking to connect these two power workgroups.

Switching to higher-speed LANs such as FDDI or ATM is not feasible for most people due to the expense of
replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance.

The ES-2024 can provide the same bandwidth as FDDI and ATM at much lower cost while still being able to use
existing adapters and switches. Moreover, the current LAN structure can be retained as all ports can freely
communicate with each other.

Figure 1-3 High Performance Switched Workgroup Application

1.2.4 IEEE 802.1Q VLAN Application Examples

This section shows a workgroup and a shared server example using 802.1Q tagged VLANs. For more information
on VLANs, see the Switch Setup and VLAN Setup chapters in this User’s Guide. A VLAN (Virtual Local Area
Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network
belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly talk to or
hear from stations that are not in the same group(s) unless such traffic first goes through a router.

Tag-based VLAN Workgroup Example

Ports in the same VLAN group share the same broadcast domain thus increase network performance through
reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without
any re-cabling.

Figure 1-4 VLAN Workgroup Application

VLAN Shared Server Example

Shared resources such as a server can be used by all ports in the same VLAN as the server, as shown in the
following example. In this example, only ports that need access to the server need belong to VLAN 3 while they
can belong to other VLAN groups too.

Dimension ES-2024 Ethernet Switch

Chapter 2

Hardware

This chapter shows two switch installation scenarios.

Installation

2.1 Installation Scenarios

The switch can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber feet in a desktop
installation and the brackets in a rack-mounted installation.

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 Procedure

Step 1. Make sure the switch is clean and dry.

Step 2. Set the switch on a smooth, level surface 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 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 switches when stacking.

Figure 2-1 Attaching Rubber Feet

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

2.1.2 Rack-Mounted 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 a rack-mounting kit.

Hardware Installation 2-1

Dimension ES-2024 Ethernet Switch

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.

Step 2. Attach the other bracket in a similar fashion.

Figure 2-2 Attaching Mounting Brackets and Screws

Step 3. 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 rack-mounting
screws.
