LinkSys SRW248G4 v1.1 Factoryreset

Hallo Zusammen,

habe durch einen Bekannten diesen Switch bekommen LinkSys SRW248G4 v1.1

Leider ist das Administrator Passwort für die Weboberfläche unbekannt.

Nach einer Recherche habe ich eine Anleitung gefunden mit der man den Switch auf Werksreset bekommen kann.

Bei Schritt 3 geht es bei mir nicht weiter.

Ich verbinde den PC mit dem Switch über ein Nullmodem Kabel. (https://www.amazon.de/gp/product/B007GLFQ8M/ref=oh_aui_detailpage_o01_s0 ..)

Nachdem ich den Serial Port nach Punkt 2 konfiguriert habe. Öffnet sich ein leeres Consolenfenster in dem ich weder was eingeben kann noch was ausgegeben bekomme.

Habe mit 3 PC´s das ganze getestet und komme immer wieder zum gleichen Ergebnis.

Benötige ich für das Switch ein anderes Kable?

Bin auf eure Antworten gespannt.


"1.) Connect the Linksys serial cable that came with the switch between the switch serial port and a nearby computer serial port. For Windows, use Hyper Terminal or VanDyke CRT/SecureCRT. For Linux, use minicom. For other unix types, try cu/tip.
2.) The switch default serial port configuration is set to 38400 baud, 8 data bits, no parity, 1 stop bit, no flow control.
3.) Confirm that you have a valid serial connection by pressing enter a few times. You should be prompted with a login screen.
4.) If you have successfully established serial communication with the switch, reboot the switch by disconnecting and then reconnecting it's power cable.
5.) The switch will begin it's POST procedure as displayed in the serial terminal emulator. Be ready at the keyboard to press the Esc key.
6.) Watch for the following line to appear during the boot sequence. When you see it, immediately press the Esc key;
"Autoboot in 2 seconds - press RETURN or Esc. to abort and enter prom."
IMPORTANT: Do not hold down the Esc or Enter/Return key during the boot sequence. Only press the Esc key when prompted.
7.) If you successfully interrupted the boot sequence, you will be prompted with a Startup Menu. Option number 3 will be the "Password Recovery Procedure". Select this option.
8.) The terminal will display, "Current password will be ignored!". Press enter to continue with the boot sequence.
9.) The default account "admin/<blank>" will be enabled and you can log into the switch using this account. From here, you can set new accounts without having lost the switch configuration.
10.) After you have configured new accounts and documented the passwords, reboot the switch and log in normally to confirm that passwords have been recovered successfully.
11.) You are done. Disconnect and store the serial cable in a safe place for future use. Be sure to document a login username and password somewhere safe for future reference."
