Re: Dell Powerconnect 2016 All leds are on, solid no...

Had same problem with my Dell Pwoerconnect 2016, power it on and all LEDs light up but nothing works.
The problem was traced to one or both output capacitors ( 10v 680uf ) on the ( tiny ) power supply.
Capacitor symptoms include bulging or rounded tops instead of flat like new one and the rubber plug in base of capacitor protruding.
Capacitors need to be replaced.
I have successfully replaced with 10v 1000uf and 10v 1200uf, both Rubycon and Sanyo brands.
Power to the switch board is now restored and the switch is able to function just fine.
Give it a go and see if it works for your Powerconnect.

Re: Dell Powerconnect 2016 All leds are on, solid no...

Are all three rows of lights on solid green?? This is either some sort of switch failure or possibly a broadcast storm, network loop condition, or defective NIC card in an attached computer.

With the lights on, try removing all of the data cables...slowly, one at a time. If the lights go off, check to see where the cable goes that you just removed. If all of the lights remain on even with no network cables attached, then the switch has probably failed. Confirm this by unplugging power and plugging back in...with no data cables...if problem returns...the switch will need to be replaced.

The Lights blinking with no cables in it? There is a problem with the power. The power to the mainboard must be 3.3 volts.
I've solved it with new condensators in the powersupply,

I forgot a password and i cant access a catalyst 2960 24-port 10/10

You can only reset password this way:
Attach a terminal or PC with terminal emulation (for example, Hyper Terminal) to the console port of the switch.
Use the following terminal settings:
  • Bits per second (baud): 9600
  • Data bits: 8
  • Parity: None
  • Stop bits: 1
  • Flow Control: Xon/Xoff
2.Unplug the power cable.
3. Hold down the mode button located on the left side of the front panel, while you reconnect the power cable to the switch
4. Release the Mode button when the SYST LED blinks amber and then turns solid green. When you release the Mode button, the SYST LED blinks green.
5. switch: flash_init
6. switch: load_helper
7. switch: dir flash:
8. switch: rename flash:config.text flash:config.old
Rename config.text to config.old. In that file the password is stored.
9. switch: boot
10. Enter "n" at the prompt to abort the initial configuration dialog
11. Type en to enable
12. Switch#rename flash:config.old flash:config.text
13. Switch#copy flash:config.text system:running-config
14. Overwrite the current passwords:
conf term
enable secret <new pass>
enable password <new pass>
line vty 0 15
password <new pass>
line con 0
password <new pass>

15. write memory
16. copy run start

I have a switch Dlink (DES-3026). All the status LEDs are blinking together with orange color. Is there any problem in that?

Blinking LEDs show data activity (Send & Receive) at the connected ports. So, there is no problem as long as the switch is performing well

Good Luck!

Remove a ACE from an ACL using CLI

Sure thing:

First to enable the web interface, try command:

ip http server

Also try:
ip http port 80

That will enable it on the default port

As for the ACL's I looked at the documention and I believe the syntax is to put a deny in front of the command and that will remove it.

Of course the GUI will be easier to deal with

The manual can be downloaded from:

No ip adress

First, at the command prompt type ipconfig /flushdns. This will purge the dns cache, then type ipconfig /registerdns. This will refresh your DHCP lease and re-register any DNS names.

After trying the ipconfig /registerdns command, wait for about 15 minutes, then check your status and see it your issue is resolved.

If not, try reinstalling your NIC drivers.
Let us know if you need further clarification.
