Switch Recovery Procedure
NOTE:
To perform switch recovery disconnect the stacking cables
connected to each switch. Connect each switch individually via the serial
port. Stack members can't be recovered unless the switch is connected
directly to serial port.
1. Connect a serial cable to the serial console port on the switch (8-No Parity-1-115200-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 115200 baud, 8 data bits, no parity bit, 1 stop bit, and no flow control).
2. 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.
3. Download 6.5.3.36 firmware to the switch using TFTP by selecting option 4 - Load new operational code
from the boot menu.
4. Verify that the firmware has been updated to the 6.5.3.36 version using the show version command.
