Switch Recovery Procedure

NOTE:

The Switch Recovery procedure requires one to connect to each

switch individually via the serial port. It will not upgrade stack members other

than the switch directly connected via the serial port. If the switches are

connected via stacking cables, disconnect the stacking cables to perform the

recovery procedure.

Connect a serial cable to the serial console port on the switch (8-No Parity-1-9600-No Flow Control).

Use the supplied RJ45 Yost to DB9 serial cable. Connect the RJ45 end to the switch console port

and the DB9 connector to your PC. Set the terminal emulation software (for example., PuTTY) to

the correct settings (default setting 9600 baud, 8 data bits, no parity bit, 1 stop bit, and no flow

control).

When the boot menu appears, select 2 – Start Boot Menu within 10 seconds of the prompt appearing. If the

boot menu does not appear after power cycling the switch, check the serial port settings and the serial cable

connections. Make sure that RTS/CTS (HW flow control) and XON/XOFF (SW flow control) are disabled

on the terminal. It is preferred to use the serial cable supplied with the switch. If you do not have the

original serial cable, it may be necessary to use a NULL modem device to access the switch via the serial

cable. Check the serial cable setup with an operational switch to verify that it works properly.

Download 6.0.1.3 firmware to the switch using TFTP by selecting option 4 - Load new operational code

from the boot menu.

Verify that the firmware has been updated to the 6.0.1.3 version using the show version command.

Update Boot Code using the hidden CLI command "update bootcode" from CLI.
