Chapter 1 Introduction

The CWGE24MODMS Managed Switch is a modular switch that can be used to build

high-performance switched workgroup networks. This switch is a store-and-forward

device that offers low latency for high-speed networking. The switch is targeted to

workgroup, department or backbone computing environments.

The CWGE24MODMS Managed Switch features a store-and-forward switching scheme.

This allows the switch to auto-learn and store source addresses in a 16K-entry MAC

address table.

The MDI (Medium Dependent Interface) Port is also called an "uplink port". The MDI

port does not cross transmit and receive lines, which is done by the regular ports

(MDI-X ports) that connect to end stations. In general, MDI means connecting to

another Hub or Switch while MDIX means connecting to a workstation or PC. Therefore,

Auto MDI/MDIX means that you can connect to another Switch or workstation without

changing non-crossover or crossover cabling.

The CWGE24MODMS Managed Switch has three module slots which provide flexibility

on network application. Users can purchase the modules in accordance with their

needs.

Chapter 3 Hardware Installation

3.1 Desktop Installation

Set the switch on a sufficiently large flat space with a power outlet nearby. The surface

where you put your Switch should be clean, smooth, level, and sturdy. Make sure there

is enough clearance around the switch to allow attachment of cables, power cord and

air circulation.

Attaching Rubber Feet

1. Make sure that the mounting surface on the bottom of the Switch is grease and

dust free.

2. Remove adhesive backing from your Rubber Feet.

3. Apply the Rubber Feet to each corner on the bottom of the Switch. These footpads

can prevent the Switch from shock/vibration.

3.2 Rack-mounted Installation

The switch comes with a rack-mounted kit and can be mounted in an EIA standard size

19-inch rack. The switch can be placed in a wiring closet with other equipment,

provided there is proper ventilation.

Perform the following steps to rack mount the switch:

A. Position one bracket to align with the holes on one side of the switch and secure it

with the smaller bracket screws. Then attach the remaining bracket to the other

side of the switch.

B. After attaching both mounting brackets, position the switch in the rack by lining up

the holes in the brackets with the appropriate holes on the rack. Secure the switch

to the rack with a screwdriver and the rack-mounting screws.

Note: For proper ventilation, allow about at least 4 inches (10 cm) of clearance on the front

and 3.4 inches (8 cm) on the back of the Switch. This is especially important for enclosed

rack installation.

3.3 Power On

Connect the power cord to the power socket at the rear panel of the switch. The other

end of the power cord connects to the power outlet. The internal power can work with

AC in the voltage range of 100-240VAC/ frequency 50~60Hz or 12-48VDC (optional).

The AC and DC input can be used for redundant power supply. When one fails, the

other is able to continue providing power to the switch. Check the power LED indicator

on the front panel to see if power is properly supplied.

 Select the proper Fiber cable to construct your network. The Fiber TX and RX port

should be connect to partner’s right fiber port. Example: TX connects to partner’s Fiber

RX connector and RX should to partner’s TX connector.

Chapter 5 Network Application

This section provides you a few samples of network topology in which the switch can be

used. In general, the CWGE24MODMS Managed Switch is designed as a segment switch.

That is, with its large address table (16K MAC address) and high performance, it is ideal for

interconnecting networking segments.

PC, workstations, and servers can communicate with each other by directly connecting with

CWGE24MODMS Managed Switch. The switch automatically learns node addresses, which

are subsequently used to filter and forward all traffic based on the destination address.

By using Gigabit or Gigabit Fiber, the switch can connect with another switch or hub to

interconnect other small-switched workgroups to form a larger switched network.

Meanwhile, you can also use Ethernet or Gigabit fiber ports to connect switches. The

following figure is an example of the CWGE24MODMS Managed Switch application

topology.

The example of application topology

5.1 Desktop Application

The CWGE24MODMS Managed Switch is an ideal solution for small workgroups.

The switch can be used as a standalone switch to which personal computers, server,

printer server are directly connected to form a small workgroup.

5.2 Segment Application

For enterprise networks where large data broadcast are constantly processed this switch is

suitable for a department user to connect to the corporate backbone.

You can use the CWGE24MODMS Managed Switch to connect PCs, workstations, and

servers to each other. All the devices in this network can communicate with each other by

connecting directly to the switch. Connecting servers to the backbone switch allow other

users to access the server’s data.

The switch automatically learns node addresses, which are subsequently used to filter and

forward all traffic based on the destination address. You can use any of the RJ45 ports of

the CWGE24MODMS Managed Switch to connect with another switch or hub to

interconnect each of your small-switched workgroups to form a larger switched network.

Troubleshooting

This section is intended to help you solve the most common problems that may occur on the

CWGE24MODMS Managed Switch.

 Incorrect connections

The switch port can automatically detect straight or crossover cable when linked with

another Ethernet device. For the RJ45 connection, use correct UTP or STP cables. The

10/100/1000Mbps port uses 2-pairs twisted cable and the Gigabit 1000T port uses 4 pairs

twisted cable. If the RJ45 connector is not correctly pinned then the link will fail. For the fiber

connection, please note that the fiber cable mode and fiber module should match.

 Faulty or loose cables

Look for loose or obviously faulty connections. If they appear to be OK, make sure the

connections are snug. If that does not correct the problem, try a different cable.

 Non-standard cables

Non-standard and miss-wired cables may cause numerous network collisions and other

network problem, and can seriously impair network performance. A category 5-cable tester

is a recommended tool for every 100Base-T network installation.

RJ45 ports: Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ45

connections: 100Ω Category 3, 4 or 5 cable for 10Mbps connections, 100Ω Category 5

cable for 100Mbps connections or Category-5e / Category-6 for above 1000Mbps

connections. The length of any twisted-pair connection should not exceed 100 meters (328

feet). The Gigabit port uses Cat-5 or cat-5e cable for 1000Mbps connections. The length

should not exceed 100 meters.

 Improper Network Topologies

It is important to make sure that you have a valid network topology. Common topology faults

include excessive cable length and too many repeaters (hubs) between end nodes. In

addition, you should make sure that your network topology contains no data path loops.

Between any two ends nodes, there should be only one active cabling path at any time. Data

path loops will cause broadcast storms that will severely impact your network performance.

 Diagnosing LED Indicators

The switch can be monitored through panel indicators, which describes common problems

you may encounter and where you can find possible solutions to assist in identifying

problems.

If the power indicator is not lit when the power cord is plugged in, you may have a problem

with the power outlet, or power cord. However, if the switch powers off after running for a

while check for loose power connections, power losses or surges at power outlet. If you still

cannot resolve the problem, contact your local dealer for assistance.
