2. Open PUTTY or Xshell or HyperTerminal with a serial connection and the following settings (19200, 8, 1, N) If not connected may use 9600 or 115200 bps

14. If you type "summary" you will see all the switch details.

Amongst these details are the IP address of the switch. If you have DHCP on your network this switch is connected to it will receive one as in my case below, so I can now configure the rest via a web browser.

If not you can use the "ipsetup" command to set a static management IP and access via a web browser.

15. Once you can access the web management page for the switch make sure you set a strong password for "admin" and store it in a secure encrypted location for next time.

16. Don't forget to save your new configuration! Otherwise the switch will be at factory defaults if the power goes off!!

Hi,
  • Turn the printer off.
  • Remove the roll and re-fix it.
  • Press and hold the green power button.
  • Turn the printer on and release button after the first flash of LED light.
  • The printer runs a self test print.
  • Turn it off and then on again.
  • Now you can print.

HI, I have two 3com patch panels 3C17302 Superstack 3 Switch 4250T, connected to a switch panel. One of the patch panels does not work e.g. the connected pc's are not able to have Lan connection. Only...


I don't know anything about these units, nor do I have time to source any docs for you, but maybe you can try connecting a PC directly to the port your patch panel is connecting the the switch from, you can at least see if that port is working.
My next and only other suggestion is to invest in a "LAN cable tester". In my area, you can find cheap ones for U$20.
The tester will allow you to check connectivity between any two ports, and allows you to test both patch links and individual CAT5/6 cables.
Good luck!

Problem with GA 8LD533


There are a few easy fixes for this, first,

Clear the CMOS (Unplug the power cord, remove the battery, and (if it's an option) move the jumper J1 (it has three pins, the jumper covers two, move it to cover the other one), unplug everything external from the motherboard apart from the PSU and power switch and speaker, replace battery, powercord, and jp1, power up - what happens?

Stacking Cable / SuperStack3 3870


Found this on 3Com website: The SuperStack 3 Switch 3870 family (3870-24 and 3870-48) can stack up to 8 units high. Stacks can be formed with any combination of 24-port and 48-port units, with a maximum of 384 (8 x 48) front panel ports supported. When connected together, a stack of units is managed as a single entity. All units in the stack need to run the same release of the operational version code (firmware). When units are stacked together, they operate in a master-slave relationship. One unit acts as a Master and the other units act as slaves. When looking at a stack of units, the master can be identified by looking at the Stack Master LED on the left side of the switch. The Stack Master LED is green for the Master. If the unit numbers are out of sync, go to the CLI command that allows users to re-number their units- system / control / renumber. This will re-number the units in the stack. It will take about a minute or two. The master is the only unit that has a visible command line interface (CLI) when a console cable is connected to it. If you connect the console cable to a slave unit, you will not see the CLI menu, but instead see slave status messages being displayed. The Master unit may not be unit 1. http://knowledgebase.3com.com/consumer/esupport.asp?id=GUIDbfa9caa4%5F138f%5F4681%5Fbaaf%5F5c99ec5b7ff4&resource=&number=0&isExternal=0&nShowFacts=&nShowCause=&nShowChange=&nShowAddInfo=&activepage=statement.asp&bForceMatch=True&strCurrentSymptom=3C17462&searchtype=normal&searchclass=&bnewsession=false&selecttype=match

3com 3300 TM - all Ethernet port not working, power led flashing


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.
