Chapter 1: Introduction of the Product

This chapter describes the features of the GS-1657/GS-2457 16/24-port Gigabit Ethernet Switch.

Overview of the Product

The GS-1657/GS-2457 16/24-port Gigabit Ethernet Switch provides you with a high-performance, low-cost, easy-to-use, seamless and standard upgrade to boost your old network to 1000Mbps. crease the speed of your network server and backbone connections make Gigabit a reality. Power users in the home, office, work group, or creative production environment can now move large, bandwidths files faster. Transfer graphics, CGI, CAD, or multimedia files and other applications that have to move large files across the network almost instantly.

GSW-1657/GSW-2457 features a non-blocking switching architecture that forwards and filters packets at full wire-speed for maximum throughput. MAC address auto-learning and auto-aging, IEEE802.3x flow control for full-duplex mode and back pressure for half-duplex mode. It is compatible with all 10,100, and 1000Mbps Ethernet devices because it is standard based, it protects your existing network investments while providing you with a straightforward migration path to faster Gigabit speeds.

The GS-1657/GS-2457 is plug-and-play and no configuration is required. Auto MID/MID-X cable detection on all ports eliminate the need for crossover cable or Up link port. Each port can be used as general ports or Up link ports, and any port can be simply plugged into a server, a hub, a router or a switch, using the straight cable or crossover cable. Diagnostic LEDs which display link status and activity, allowing you to quickly detect and correct problems on the network.

Chapter 2: Installation

Mounting the Switch on a Desk

Before place the Switch on a desk, attach four rubber foot pads to the flutes on the Switch bottom, then lay the Switch on the desktop, where can be have as much as 5kg placed on top.

Note:
Make sure there is a grounded AC outlet within 1.5 meters, and working well.

Make sure there is free space for radiating heat and air.
Make sure not to place anything to heavy on top of the switch.

Mounting the Switch in a Rack

The dimension of GSW-1657/GSW-2457 is designed according to the standard 19 rack-mountable steel case of Electronic Industries Association. Turn off all the equipment connected to the Switch before mounting it in the rack, then rivet the two “L” brackets onto each side of the Switch, fasten it with screws in the rack.

Figure 2-1 Rivet the “L” brackets onto the Switch

Figure 2-2 Fasten the Switch in the rack

Power On

GSW-1657/GSW-2457 16/24-port Gigabit Ethernet Switch is powered by AC power supply. Powering on the Switch, it will automatically initialize and its LED indicators should respond as follows:

1. All of the Link/Act and 1000Mbps LED indicators will flash momentarily for one second, which represent a resetting of the system.
2.  The Power indicator will light up.
3. The FAN LED indicators will light up.

If the LED indicators don’t respond as described above, please check the power supply and connection.

Chapter 3: Identifying External Components

This Chapter describes the front panel, rear panel and LED indicators of the Switch. GSW-1657 and GSW-2457 just differ in the number of LED indicators and ports and all figures in this guide are of GSW-2457.

Front Panel

The front panel of the GSW-2457 consists of switch LED indicators, 24 10/100/1000Mbps RJ-45 ports.

Rear Panel

The rear panel of the GSW-2457 only features a power receptacle, which is an AC power receptacle. Connect the female of the power cord head here, and the male head to the AC power outlet

LED Indicators

The LED indicators include Power, FAN, Link/Act and 1000Mbps LED indicators, which are used for monitoring and pre-troubleshooting of the Switch. The following section shows the LED indicators for the switch along with an explanation of each indicator.

• Power LED: This indicator will light solid red when the Switch powers up. If the LED is not lit, please check the power supply and connection.
• FAN LED: This indicator will light solid green when the corresponding cooling fan works properly.
• Link/Act LED: This indicator will light solid green when the corresponding port is connected to another device and will flash green when data is being transmitted or received on the working connection.
• 1000Mbps LED: This indicator will light solid green when the corresponding port is connected to a 1000Mbps device.
