A blinking power LED means that the switch is either downloading software, or is initializing which also includes running the Power On Self Test. You may have firmware issues with the switch and/or the switch is stuck in initialization mode. You may have to contact 3com regarding a warranty issue. Hope this helps. Good luck.

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

Well I think the port is bad, I had one that did something similar to your problem. I got on the 3Com website and submitted and RMA request and they upgraded my with the newest model. But if yours is still in stock they will replace with the same type. That is what I would do. Hope this helps ya.

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.

Configuring a 3COM 3CRWDR200A-75 router as a repeater


SETTING A ROUTER AS A REPEATER 1. Connect your computer to the repeater router's RJ45 port with a LAN cable. 2. Open a browser, then enter the router's URL configuration's IP address, This is usually something similar to 192.168.0.1 3. Enter the configuration user name and password. The router will display the various router settings. 4. Go to the page that changes the IP address of the router. Changed the IP address so that it is not the same as the main router on the network, or any other network devices. If the main router on the network is set to 192.168.1.1 then the repeater router should use a higher number (ie. 10), such as 192.168.1.10 or higher, depending on how many devices are on your network. 5. Disable the repeater router's DHCP server. This setting should be on the same page as the IP address, (this may be different depending on the make of the router). When the main router is operating normally, this server assigns an IP address to every device that is connected to your network. Because this router is used as a repeater, the main router on your network will still issue the IP addresses. 6. Also turn off the DNS server, if it is activated. This function will be taken over by the main router. 7. Disable any firewall settings on the repeater router. This is usually in the "Security" section, depending on the make and model of your router. 8. Remove all in the "Port Forwarding" section. Some routers may refer to this as "Applications and Gaming," and it allows less-restricted access to the internet. 9. Set the operating mode switch to "Gateway" or "Switch" if applicable. Also, if the repeater router is a wireless router then disable the wireless access or set it to access point only. 10. Save the settings for each page, and reboot the router. When the router boots up, the changes will allow it to act as a simple repeater. 11. Now, place the repeater router in a new location and connect both routers with a Ethernet cable in each of the router's RJ45 LAN ports, and power it up both routers.

My problem is i have all yellow ports flashing in 10 3com 3300 switches in the same time. please help me


  1. Using a Null-Modem Cable , hook up the Console port of the switch to an available COM port on a computer (cable must be able to provide serial port communication between 2 computers).
  2. Set up a Hyperterminal session to that COM port (e.g.: com1), with the port settings at 9600/8/N/1/N (. When the screen comes up blank with a blinking cursor, hit [enter] once or twice to bring up a login prompt.
  3. Alternative to 1 and 2 above, if there is a known assigned TCP/IP address for the switch, one can telnet to that address, hit [enter] once or twice to get the login prompt.
  4. Default logins to try are admin/(no password) or security/security. One of those 2 should bring up the management menu.
  5. To reset factory defaults, type SYSTEM[enter] then type INITIALIZE[enter]. This will reset everything that has been set up on the switch, with the exception of the TCP/IP address, if there is one. All other previous configurations will need to be re-entered.
  6. You can type in username "3comcso" and password "RIP000". It will ask you to reinitialize the switch. This will reset all settings including passwords.

Sir I have 4200 series 26 ports Switch i want to Configure intra VLAN But I am Getting a problem to Configure that switch . After Cnfigure VLAN on Consol prompt. I am not accessing to my Server & WAN...


Hi,
If you are creating only Layer 2 VLANs on the switch , you wont be able to ping the servers and Routers as they are in default VLAN1.
you can do the below steps
1. Create sub interfaces on the router LAN interface
2. Provide a new ip range to the new sub interface
3. Make the switch port connecting router as trunk, so that it will carry both the VLAN info
4. on your Labtop/PC give the IP address in the newly defined range
5. Make your switch port to be in the new VLAN

This will work , if you wont be able to configure the above settings, let me know i will give you the detailed config

3com 8 port hub not connecting to 2nd pc


Be sure that when you say its a hub that is indeed a layer 1 device which is just passing the signal and data along to all ports. Be sure to check the cable on the second device. At this point it must a straight cable you use to connect the PCs to the Hub. PCs transmit on pins 1 & 2 and Receive on 3 & 6. Hubs are the opposite. So a crossover will not work. You need PC pin 1 & 2 Tx to Hub Pin 1 & 2 Rx and over to PC pin 3 & 6 Rx to Hub pin 3 and 6 Tx. Tx = transmit and Rx = Receive. Also assign an IP address on each machine that is in the same subnet as each other. Such as PC1 192.168.1.100 mask 255.255.255.0 and PC2 IP address as 192.168.1.101 Subnet Mask 255.255.255.0 This way the 192.168.1 is the same for 8 PCs and the only change is the last number (octet). Also keep the speeds at either 10/100/1000 what ever the product is rated for but always keep the duplex half. Half is good because on a layer 1 hub, everyone is broadcasting at the same time. So you have to have half of all the ports listening at all times.

I hope this helps. My advice is to buy a layer 2 switch.
