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


You can only reset password this way:
1.
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>
login
line con 0
password <new pass>

15. write memory
16. copy run start

I am trying to add an additional PoE device, put it will not power up. How can I tell the switch to power up a specific port, or put the switch into automatic mode?


Are you within the power budget?

Power feeding of Ethernet is limited for fixed 10BASE-T/100BASE-TX ports. The solution can provide maximum output power per PoE port up to 15.4W on 12 ports or 7.5W on 24 ports simultaneously. The Switch provides independent overload and short-circuit protection for each port, LED indicators for power status per PoE port, and supports IEEE802.3af MIB for Power over Ethernet functionality.
For each attached 802.3af-compliant device, the Switch automatically senses the load and dynamically supplies the required power. The Switch delivers power to a device using the two data wire pairs in the twisted-pair cable. Each port can provide up to 15.4W of power at the standard -48 VDC voltage.

The light may stay on due to static in the switch. It will automatically go off after some time when the static gets discharged.

Cisco 2900xl switch - can't type anything in console?


Please try using Hyperterminal, it's in accessories> communications>
Use com port and click on "restore default" on next window and then ok. Then try typing it will probably work.
The console port is fine as you can see all the outputs coming from there.
Try changing the settings in putty under keyboard, make sure the bit rate selected is 9600bps.

Default pasword


Cisco switches dont have a default password.
You will have to perform a password recovery process that is quite extensive.
You need to console into the switch using hyperterminal or teraterm and follow these instructions located at: http://www.cisco.com/en/US/products/hw/switches/ps628/products_password_recovery09186a0080094184.shtml

Cisco catalyst 3500xl (24 port) bad console


It is possible that your console port is configured for a different baud rate. Try to change your baud rate on your hyper terminal going from 115200 down to 2400. If it doesn't work you might have a problem with 232 driver chip that is located on the board next to your console port. You will not be able to find a schematics for this switch, it is not available for the public.
You can send this switch to me. I will glad to fix it for you.

Good luck.

Connecting to console


The proper way to console to a switch (at least as far as Cisco Catalyst Switches are concerned) is a rollover cable and a DB9 adapter... I then use HyperTerminal to connect..

What type of switch are you connecting to, and what kind of hardware are you using?

I always use Cisco for networking (Cisco is the king of switches and routers).. here is their step by step for connecting to one of their swtiches:

Hardware Problem


Probably a bad power supply. Is it getting through power on self test? Any LEDs illuminated when you power it on? Best way is to first connect a terminal configured at 9600,N,8,1 to the console port and then power it on. If you see it running through self test in a few (10-30) seconds, then it's starting up, watch the screen for any errors. If not, then your power supply is probably shot.
