Chapter 1 Introduction of the Product

This chapter describes the features of the model of FSW-1650/FSW-2450

16/24- port 10/100 Rackmount Switch. FSW-1650 and FSW-2450 just

differ in the number of LED indicators and ports, all figures in this guide

are of FSW-2450.

1.1 Overview of the product

FSW-1650/FSW-2450 6/24-port 10/100 Rackmount Switch provides

16/24 10/100Mbps Auto-Negotiation RJ45 ports. Each port of the FSW-

1650/FSW-2450 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, using

straight cable or crossover cable.

The LevelOne FSW-1650/FSW-2450 16/24-port 10/100 Rackmount

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.

1.3 IEEE 802.1p QoS

The FSW-1650/2450 16/24-Port 10/100M switch supports 802.1p priority

queuing Quality of Service, 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 two priority queues labeled 0 and 1. The untagged

packets and the eight IEEE 802.1p priority levels defined by the standard

are mapped to the two class queues used on the switch. Class 1 has

the higher priority of the two priority queues on the switch. The untagged

packets and eight priority tags, specified in IEEE 802.1p are mapped to

the switch’s priority as follows:

The untagged packets and priority 0,1,2 and 3 are assigned to the

switch’s class 0 queue.

Priority 4,5,6, and 7 are assigned to the switch’s Class 1 queue.

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 Class 0 queue and Class 1 queue is 1 to 8.

Chapter 2 Installation

2.1 Mounting the Switch on a Desk

Before placing the Switch on a desk, attach four rubber feet to the flutes

on the Switch bottom, then lay the Switch on the desktop,

where it is able to withstand 5kg of weight.

)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.

2.2 Mounting the Switch in a Rack

The dimension of FSW-1650 / FSW-2450 is designed according to the

standard 19” rack-mountable steel case of Electronic Industries

Association.

Powers 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,

and 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

2.3 Power on

The FSW-1650/FSW-2450 16/24-port 10/100 Rackmount switch is

by power cord. Powering on the Switch, it will be automatically initialized

and the LED indicators should respond as follows:

1) All of the LED indicators will flash momentarily for one second,

which represent a resetting of the system.

2) The Power LED indicator will light up.

Chapter 3 Identifying External Components

This Chapter describes the front panel, rear panel and LED indicators of

the Switch.

3.1 Front Panel

The front panel of FSW-2450 consists of switch model, switch LED

indicators, and 24 10/100Mbps RJ-45 ports.

3.2 Rear Panel

The rear panel of FSW-2450 only features an electrical outlet, which is an

AC electrical outlet. Connect the female of the power cord head here, and

the male head to the AC power.

LED indicators

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 an explanation

of each indicator.

Figure 3-3 FSW-2450 Switch LEDs sketch

¾Power 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.

¾LINK/ACT LED: The LED indicates Link/Active status. The

corresponding LED indicator will light solid green when connected to

a network device. It flashes green when data is being transmitted or

received on the working connection.

¾100Mbps: The corresponding gigabit port LED indicator will light

solid green when it's working on 100Mbps speed, not lit when

working on 10Mbps speed.
