Chapter 1: Product Introduction
Product Overview
Features
1.1
1.2
This chapter describes the features of the model of LP-SW2400S 24-port
10/100Mbps Fast Ethernet Switch.
LP-SW2400S 24-port switch provides 24 10/100Mbps Auto-Negotiation
RJ45 ports. Each port of the LP-SW2400S supports auto MDI/MDI-X
function, eliminating the need for crossover cables or Uplink ports. The
switch is Plug-and-Play and any port can be simply plugged into a server, a
hub or a switch by using straight cable or crossover cable.
The LP-SW2400S 24-port 10/100Mbps Fast Ethernet Switch provides you
with a low-cost, easy-to-use, high-performance, seamless and standard
upgrade to improve your old network to a 100Mbps network. It will boost
your network performance up to full duplex data transfer.
The LP-SW2400S switch supports Energy-Smart technology, with power
saving features to help make your network environmentally friendly without
compromising performance. The switch automatically powers down ports
that have no link and budgets power output for different Ethernet cable
lengths. It can also reduce the power consumption in idle mode or with low
trafc mode.
►Complies with IEEE802.3, IEEE802.3u, IEEE802.3az, IEEE
802.1p standards.
►24 10/100Mbps Auto-Negotiation RJ45 ports supporting Auto-
MDI/MDIX.
►Supports IEEE802.3X ow control for full-duplex mode and
backpressure for half-duplex mode.
►Supports IEEE 802.1p QoS.
►Supports power saving features, with Energy-Smart Technology.
►LED indicators for monitoring power, link and activity.
►Desktop or 19 Inch Rack mountable 11.6 Inch wide Small Form
Factor (SFF) Steel case.
►Internal power supply.
►Plug and Play

IEEE 802.1p QoS
1.3
The LP-SW2400S switch supports 802.1p priority queuing Quality of
Service (QoS), which is an implementation of the IEEE 802.1p standard.
With 802.1p QoS function, you can reserve bandwidth for important
functions that require a large bandwidth or have a high priority, such as
VoIP (Voice-over Internet Protocol), web browsing applications or video
conferencing. The switch has separate hardware queues on every physical
port which packets from various applications are mapped to and assigned
a priority to. The illustration below shows how 802.1p priority queuing is
implemented on the switch.
The switch has four priority levels labeled TC0, TC1, TC2 and TC3. The
untagged packets and the eight IEEE 802.1p priority tags dened by the
standard are mapped to the four level queues used on the switch. TC3
has the highest priority of the four priority level queues while TC0 has the
lowest priority on the switch. The untagged packets and eight priority tags,
specied in IEEE 802.1p are mapped to the switch’s priority tags as follows:
The switch uses WRR (Weighted Robin Round) for scheduling. WRR
queue-scheduling algorithm schedules all the queues in turn and every
queue can be assured of a certain service time. The default weight value of
TC0, TC1, TC2 and TC3 is 1:2:4:8.
Figure 2. Mapping QoS on the Switch
►The untagged packets, packets with priority tag 1 and 2 are
assigned to the switch’s TC0 level queue.
►Packets with priority tag 0 and 3 are assigned to the switch’s
TC1 level queue.
►Packets with priority tag 4 and 5 are assigned to the switch’s
TC2 level queue.
►Packets with priority tag 6 and 7 are assigned to the switch’s
TC3 level queue.

►Power LED: This indicator will light solid green when the switch
powers up. If the LED is not lit, please check the power supply and
connection.
►Link/Act LED: The LED indicates Link/Active status. The
corresponding LED indicator will light solid green when connected to
a network device. It ashes green when data is being transmitted or
received on the working connection.
Chapter 2: Identifying External Components
This chapter describes the front panel, rear panel and LED indicators of
the switch.
Front Panel
2.1
The front panel of LP-SW2400S consists of switch model, switch LED
indicators, and 24 10/100Mbps RJ-45 ports.
The LED indicators include Power, Link/Act LED indicators, which are used
for monitoring and pre-troubleshooting of the switch. The following section
shows the LED indicators of the switch along with explanation of each
indicator.

Chapter 3: Installation
To ensure a long-term and stable performance of the switch, please pay
attention to the following before the installation.
Precautions
1) Safety Requirements:
3.1
▪Before cleaning the switch, cut off the power supply. Do not
clean it by the waterish cloth, and never use any other liquid
cleaning method.
▪Take waterproof measures during storage, transportation and
operation of the equipment.
▪Use only the power cord provided with the switch.
▪Make sure the voltage of the power supply meets the
requirement of the input voltage of the switch.
▪Do not push any objects into the openings of the switch.
▪Ensure the vent hole is well ventilated and unblocked.
▪Do not open or remove the cover of the switch.
