GES-2450 is a powerful, high-performance Gigabit Ethernet switch with 24*10/100/1000Mbps
ports and 4*SFP (mini GBIC) ports, providing you a cost-effective, space-saving solution for
expanding your network. The gigabit ports can lead you to a real gigabit connection, making you
be able to transfer high bandwidth-needed files larger and faster in an easy way. And the four mini
gigabit ports allow you to add fiber-optic connectivity for connecting to other network switches to
obtain long-distance communication.
This device provides the easy management function through the Ethernet Web. The network
administrator can configure the status and the port function setting of the device through the
Web-Based UI. When installing the auto-discovery management tool helps network managers to
search and access those switches on LAN easily. Therefore, network managers can access
switches that support auto-discovery on LAN without memorizing IP address.
Smart Features
GES-2450 provides rich features including Link Aggregation, VLANs, IGMP Snooping, Port
Trunking, Spanning Tree, Security (Port Security and 802.1x authentication) and other network
management to meet the requirements evolving medium and small-sized enterprises. QoS secures
the bandwidth for some bandwidth-demanded applications including VoIP or video conference.
Additionally, IEEE 802.3az Energy Efficient Ethernet ability is supported to promise operation in
Low Power Idle Mode and save power consumption.
Easy Installation and Management
This switch is plug & play and hassle-free in installation. Auto-MDI/MDI-X crossover on all ports
eliminates the need for crossover cables for connection to another switch or hub. Auto-Negotiation
on each port senses the link speed of a network device and intelligently adjusts for compatibility
and optimal performance. This switch also features diagnostic LEDs, which display the status and
activities of the LEDs, allowing you to quickly detect and correct problems on the network.

To power on the switch, please plug the female end of the power cord firmly into the receptacle of
the switch and the other end into an electric service outlet. After the power cord installation, please
check if the power LED is lit for a normal power status.
1.5 Installation
This switch can be placed on your desktop directly, or mounted in a rack. Please refer to the
instructions for installation.
Before installing the switch, we recommend:
1. The switch is placed with appropriate ventilation environment. A minimum 25 mm space
around the unit is recommended.
2. The switch and the relevant components are away from sources of electrical noise such as
radios, transmitters and broadband amplifiers
3. The switch is away from environments beyond recommend moisture
Desktop Installation
1. Install the switch on a level surface that can support the weight of the unit and the relevant
components.
2. Plug the switch with the female end of the provided power cord and plug the male end to the
power outlet.
Rack-mount Installation
The switch may be standalone, or mounted in a rack. Rack mounting facilitate to an orderly
installation when you are going to install series of networking devices.
Procedures to Rack-mount the switch:
1. Disconnect all the cables from the switch before continuing.
2. Place the unit the right way up on a hard, flat surface with the front facing you.
3. Locate a mounting bracket over the mounting holes on one side of the unit.
4. Insert the screws and fully tighten with a suitable screwdriver.
5. Repeat the two previous steps for the other side of the unit.
6. Insert the unit into the rack and secure with suitable screws.
7. Reconnect all the cables.
Installing Network Cables
1. Crossover or straight-through cable: All the ports on the switch support Auto-MDI/MDI-X
functionality. Both straight-through or crossover cables can be used as the media to connect the
switch with PCs as well as other devices like switches, hubs or router.

2. Category 3, 4, 5 or 5e, 6 UTP/STP cable: To make a valid connection and obtain the optimal
performance, an appropriate cable that corresponds to different transmitting/receiving speed is
required. To choose a suitable cable, please refer to the following table.
The cable type differs from the mini-GBIC you choose. Please
refer to the instruction came with your mini-GBIC.
