Question about 3Com 5500G-EI

1 Answer

The switches under 3Com 5500G- EI cannot communicate each other

We have core switch 3Com 5500G-EI

Recently we find the PC in 100M switch cannot communicate with the PC in 1000M switch, as well as reverse.

All switches connect to core switch 3Com 5500G-EI

Please kindly advise

Thanks and Best Regards

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: Wants to reset 3824 3com switch via console

You forget the password for the "admin" user account and can no longer perform important management operations. solution.gif Use the password recovery method outlined below to define a new password for the "admin" user account:

  1. Access the Command Line Interface from the console port and enter the user name "recover" and password "recover" to place the Switch in password recovery mode. The Switch remains in password recovery mode for a maximum of 30 seconds, before it returns to the CLI login prompt.

    note.gif You must use the console port to recover the passsword. If you attempt the recovery method using the network, the password will be rejected.

  2. Perform a hard reset on the Switch whilst it is in password recovery mode by switching it off, waiting a few seconds, and switching it on again.

    note.gif You cannot use a soft reset operation to reset the password of the "admin" user account. This will end the password recovery procedure and return you to the CLI login prompt.

  3. When the Switch has rebooted following the hard reset enter a new password for the "admin" user account.

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.

SOURCE: i forgot my admin password

If it's the Power Plus (3C16475BS) model, there should be a reset button inside a small hole on the back. "10 - Recovery Button" Inserting a paperclip or similar to reset. If it's not the Power Plus model and is in fact (3C16475A), this is an unmanaged switch, with no administrative capabilities. You don't need a password.

3com Switch Intermittently Losing Connection.


this could be a problem with the second switch unit. what happens if you connect a pc to this cable, is that intermittent, if so, that is your problem. try fault finding with a LAN cable tester to see if there's any issue with the link cable.

Hello,

I have not worked with 3Com switches only Cisco, but I thought I would post this as I found it when googling:

multicast routing-enable pim
on the vlan interfaces:

interface Vlan-interfacex
ip address ***.***.***.*** ***.***.***.***
igmp enable
pim dm

Those commands should help you get multicasting to work. notice, Vlan-interfacex means you will have to do it for each Vlan you created. Some switches do not include multicast support in their base models but make you buy additional licenses to enable it. Cisco is like that, not sure about 3Com.

Some of the ports are flashing. some are not


Typically non flashing port lights means that there is nothing connected to those ports and no communication is happening. data movement and communication fires off the lights.

I have two des-1005d network switches. i want to communicate betwwen them with a cat5e cable. the cable is made as cross through and distance is about 70 meters. with one switch pc is connected and at...


Max distance for Cat5e cable is about 100M, but that is the best case scenario, essentially a straight line, down a building. If you have any kind of interference, like flourescent lighting, high voltage lines running parallel to the ethernet cable, the distance will be much less than 100M. Although it looks like you have 60 feet to spare, anything interfering with the cables will cut the signal down. Try to move the switches closer together, make the cable from pc to switch longer and ADSL modem to switch longer and cable between switches shorter. Use a known good straight through ethernet cable, as modern switches don't require crossover cables.

From Wikipedia: http://en.wikipedia.org/wiki/Category_5e#Maximum_cable_segment_length

According to the ANSI/TIA/EIA standard for category 5e cable, (TIA/EIA 568-5-A[5]) the maximum length for a cable segment is 100 meters (328 feet). If longer runs are required, the use of active hardware such as a repeater, or a switch, is necessary.[6] [7] This 100 meter limit is all inclusive. According to some authors,[who?] the practical limit for permanently installed cable is about 90 meters, leaving 5 meters at each end for the patch cables that connect the end equipment to the wall panel.

Hope this helps.

I cann't connect to my switch


The primary connection method for those switches would be serial connection. In the box there should have been a DB9 serial to RJ45 cable. Hyperterminal default settings would allow you to connect.
