Port on switch not lighting up.

I have a small network that I am taking over from another support company. My client would like to add a couple more computers to two of their switches. The ports all seem to be enabled, but none of them light up when connected to a pc. I am wondering if there is anything I might have to to activate them... Through the web control panel the ports are listed as enabled[inactive]. It was my assumption that even if the connection isn't configured that the nic on the pc and the light on the switch should light up when connected.

    so you mean that all of the 24 ports of the switch do not blink as soon as you connect an utp cable from a pc?have you tried another cables?,have you tried to connect differents pcs?

Do the ports work when the cables are connect?  I did some re-search and this seems to be an ongoing issue with 3com switches.  It should not effect the use of the switch

SOURCE: i cann't connect to my switch

Your superstack 3 should have a 9 pin male connector at the back labeled "console port" you need to connect this to your serial interface on your pc or laptop. With 3Com you also need to set your baud rate to 19200 as this the default for 3Com.

Port forwarding on dlink adsl2 router

Step 1. Before you open ports in your router, set the computer (or the device) which requires
ports to be opened for, with a static IP address. You can choose any IP address from the
range of addresses you are using on your local network, as soon as it is not used by any other
device. The default range is from 10.1.1.2 to 10.1.1.254. In our example we are using
10.1.1.99.
Windows XP: Control Panel > Network Connections > Local Area Connection > Properties >
Internet protocol TCP/IP > Properties
Windows Vista: Control Panel > Network and Internet > [Network and Sharing Centre] > View
Network Status and Tasks > View Status > Properties > Internet Protocol v4 > Properties
Select the “Use the following IP address” option:
IP address: 10.1.1.99
Subnet mask: 255.0.0.0
Default Gateway: 10.1.1.1 (your router’s address)
DNS: 10.1.1.1 and 61.88.88.88 (or whichever your provider is using)
Now open the necessary ports in your router and redirect the traffic to the 10.1.1.99 address.
Here are the steps:
How to open ports in your router Page 2 of 6
Step 2.
Open your web browser and enter the IP address of the router (http://10.1.1.1). Enter
user name and password (default username “admin” and password is “admin”).
Step 3. Click on Advanced at the top and then click on LAN Clients.
How to open ports in your router Page 3 of 6
Step 4
. You will need to add a LAN Client (the address of your computer or a device) into the
router before you can open any ports. Type in the IP address of the Computer/Device (the
one you assigned in Step 1). You can specify the name of this workstation under Host Name
(optional). Click Add and then Apply.
Step 5. Go to Advanced > Virtual Server (Port Forwarding). There is a list of pre-set ports in
the router which you can choose from.
How to open ports in your router Page 4 of 6
Step 5a.
If your specific application is not listed there, you can add the necessary ports
yourself. Select the “User” Category and click on Add button below.
Step 5b. Enter a name for this entry under Rule Name. Then select the necessary protocol. If
there is a range of ports to open, specify the starting port under Port Start and the ending port
under Port End. If you need to open just one port, specify this port number in all fields
including the Port Map. Click Apply.
How to open ports in your router Page 5 of 6
Step 6.
Go back to Advanced > Virtual Server. Under LAN IP select your LAN Client (which
you added in Step 4). Select the Category and the desired Rule or select “User” Category
and you should see the rule which you have created in Step 5b. Select it and then click on
Add > to move it into the Applied Rules section. Click Apply.
Step 7. To save the new settings into the router's memory go to Tools > System. Click on
Save and Reboot button. The router will save the settings and restart.

Use two computers with one printer

Printer Sharing (This is good for Windows 2000, XP and Vista)
Sharing will be very easy if your network is working.
You need to consider the computer where the printer connected as the "Host" and the other computer that wants to print to that printer as the "Client".
Before you do such sharing, you need to acquire each computer's IP address.
You can do it by accessing MSDOS Prompt and typing in ipconfig/all. Write down your IP addresses and the share name on a paper.
For your Host:
Install the driver, make sure that you can print on direct bi-directional connection (such as USB).
Go to Control Panel >Printers and Faxes* >Sharing >Share this printer >Type in your share name, good example is PRINTER (this is case sensitive).
For your Client:
Install the driver, make sure that you can print, same with the Host.
Go to Control Panel >Printers and Faxes* >Properties >Ports >Add Port >Add local port type in \\ (the IP Addressof the Host) \ (share name), click OK.
ex. \\192.168.1.3\PRINTER (watch your backslash, no spaces)
*Term used is "Printers" for Windows Vista and Windows 2000

AXIS CD TOWERS

Hi,

I am assuming that you are referring to the tower (desktop) as the server while the laptop is the client. While the client can access the server's CD drive, you can not ping the server. A couple of ideas:
1. verify that both server and client belong to the same Workgroup;
2. verify that both server and client have the same Subnet Mask and that their satic IP adds are near each other;
3. Server's firewall settings/configurations does not allow/prevents ping response; and/or
4. the server might be using Zonelab, McAfee Firewall, Microsoft ICF SP2 or some other form of port blocking.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Emule Show Low ID on Client Computer

Dear sir/madam,


You can update the servers it may be become fast. Go this site and add all servers (add to emule) click this link, they automatically update the servers.

http://ed2k.2x4u.de/index.html

OR try this

First of all you need to know the IP of the computer that you use with Emule.

Then go to the router configuration:

- Choose "NAT Settings", and "Virtual Server".

1- If it isn't enabled, enable the "Virtual Server".

2- In "Well-Known Applications" choose de option "User defined".

3- Now the crucial part. Under the Virtual Server List, in the "Local IP" you place the IP of your computer (on the example, 192.168.1.2, i.e. my emule computer ip), "Port Range" put 4662 and Protocol TCP. "Protocol nº." stays blank, and in the "description" you can put Emule Rule Nº1.

4- Click ADD, to add the rule to the table.

- Again you make the same passes from 3 to add the second rule:

3- In the "Port Range" you place 4672 instead 4662, and on Protocol you place UDP instead TCP. On "Description" you can place Emule Rule Nº2.

4- Click ADD.

5- After making the 2 rules, click Finish, and on the next screen click on Save&Restart button.

In the next time you start Emule, you can acess to the servers without Low ID.
