Chapter 5 Network Connection

5.1 Connect ISCOM 1024E

z Use UTP3 or UTP5 to connect 10BaseT with ISCOM 1024E

z Use UTP5 to connect 100BaseT with ISCOM 1024E

z The cable should not more than 100m in IEEE stander.

5.2 Connect ISCOM1024E with other Ethernet switch or HUB

ISCOM1024E can connect other 10/100switch, Support MDI or MDI-X.

The connected method as follows:

1. MDI to MDI-X: use Straight-through to connect ISCOM1024E with other switch or HUB

2. MDI-X to MDI-X: use Cross-over to connect ISCOM1024E with other switch or HUB

5.3 Application

An Ethernet Switch is a LAN interconnection device which operates at the data link layer (layer 2) of the OSI reference
model. A switch is fundamentally similar to a bridge, but usually supports a larger number of connected LAN segments
and has a richer management capability. Modern LANs have increasingly replaced the shared media with a switched
media, by installing Ethernet switches and bridges in place of hubs and repeaters. These logically partition the traffic to
travel only over the network segments on the path between the source and the destination. This reduces the wastage of
bandwidth which results from sending the packet to parts of the network which do not need to receive the data. There are
also benefits from improved security (users are less able to tap-in into other user's data), better management (the ability
to control who receives what information (i.e. Virtual LANs) and to limit the impact of network problems), and the
ability to operate some links in full duplex (rather than half duplex required for shared access).

6.1 Placed ISCOM1024E on a desk

Put ISCOM1024E on a desk, connect a cable with ISCOM1024E

Chapter 7 Trouble shooting

7.1 How to resolve link LED off

The possible reasons are following:

z the power supply is off
z the type of cable is not right one
z physical interface of switch has some problem
z environment, such as building

7.2 Q & A

1. Computer A can access computer B through Ethernet switch. However, computer A can not access computer C.
9 Computer A and computer C are maybe not in the same VLAN. Please check the VLAN configuration through

console port.

9 The network has some problem including Computer C. please check LED LNK/ACT of computer C and try to

connect other device using this interface.

9 Please check the NIC configuration of computer C.

2. there is no menu in console

9 The values of the connecting parameters of the terminal simulation program on the PC are as follows:

 Baud Rate: 9600
 Data Bit: 8
 Stop Bit: 1
 Parity Bit: None
 Flow Control: None

9 Confirm whether the console cable has been connected to ISCOM1024E
9 Confirm whether the console cable is CBL-RS232-DB9F/RJ45-A-2m
9 Confirm whether console port on PC has been enabled

3. Why Up-Arrow and Down-Arrow key do not take effect?

ISCOM1024E can not identify these two keys because console didn’t send it right
