Chapter 1 Overview

1.1 Product Overview

The Linkskey LKS-SG2419 Gigabit Ethernet Switch meets data transmission

demands of Internet bar/enterprise in one cost-effective, rack mountable and green

design. All 24 RJ45 ports support auto MDI/MDI-X, no need to worry about the cable

type, simply plug and play. The Auto-negotiation on each RJ45 port senses link speed

(10/100/1000Mbps) and duplex mode (full/half duplex mode) of its link partner and

adjust itself for optimal performance.

1.2 Features

Compliant with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3az

24 x 10/100/1000M auto negotiation RJ45 Ports

Backplane bandwidth up to 56Gbps for better throughput

All ports support wire speed forwarding

Auto MDI/MDI-X on each port

IEEE 802.3x flow control in full duplex; Backpressure flow control in half duplex

Built-in switch mode power supply for better stability

Green design reduces energy consumption by up to 40%

Low power consumption and fanless design saves noise interference

Plug and play

19” rack mount

Chapter 2 Installation

2.1 Installation Considerations

To keep the switch in optimum working condition and prolong its lifetime, follow the

instructions below for installation:

1. Please keep the switch in a dry and well ventilated environment to avoid

possible poor stability due to excessive dust and humidity.

2. Place the unit in a safe and stable surface to avoid any possible damage

from falling.

3. Ensure an over 10cm space around the switch for proper heat dissipation.

4. Do not put heavy articles on the Switch.

5. Make sure there is an over 1.5cm vertical distance between units that overlap

each other.

6. Ensure operating power supply accords with rated input standard.

2.2 Installation Methods

There are two ways to physically install the LKS-SG2419 24-port Gigabit Switch: Set

the Switch on an operation desk and mount the Switch in a standard-sized, 19-inch

rack.

1. To set the switch on an operation desk, do as follows:

Correctly attach the included four rubber foot pads to switch’s bottom and then set it

stably on the operation desk.

Figure 3. Attach foot pad to Switch

2. To mount the switch in a 19-inch rack, do as follows:

1) Make sure the rack is stable and well grounded.

2) Attach the included mounting brackets to both sides of the switch with the included

screws.

3) Maneuver the bracket to make sure that the slots match and line up with screw

holes, then insert screws to fix the switch.

Chapter 3 Connect Switch to a Terminal

1. Connect the switch to a power outlet nearby using the included power cord. Make

sure the power supply accords with specified rating: 100-240V~ 50/60Hz.

Chapter 4 Troubleshooting

4.1. Power LED doesn’t light up. Check the following:

a) Check whether the power cord is correctly connected or not.

b) Verify that power specification accords with specified rating.

4.2. Link/Act LED doesn’t light up. Problems and solutions may be:

a) The switch is not correctly connected to the remote device. Please

connect again with a new network cable.

b) Network cable length is beyond the standard range. Please reduce the

cable length between the switch and device to the standard range (The

standard distance is 100 meters.) or try a shorter cable.
