• To enable a TFTP boot after restoring factory default settings, you must stop the boot process using
the boot-line interface (BLI).
• The tftpboot command does not work after you perform a reset bootvar because the
management IP address, network mask, and gateway IP address are all reset to NULL.
In case the system fails to reload the image from a flash partition, follow these steps:
1. Power-cycle the chassis (pull the power cord and reinsert it).
2. When prompted by the system, press the Esc key to abort the boot process.
You are placed in the boot-line interface (BLI) at the BOOT_USER # prompt.
Press any key
3. Assign the new location of the FTOS image to be used when the system reloads.
To boot from flash partition A:
BOOT_USER # boot change primary
boot device : flash
file name : systema
BOOT_USER #
To boot from flash partition B:
BOOT_USER # boot change primary
boot device : flash
file name : systemb
BOOT_USER #
To boot from the network:
BOOT_USER # boot change primary
boot device : tftp
file name : FTOS-SI-9-5-0-169.bin
Server IP address : 10.16.127.35
BOOT_USER #
4. Assign an IP address and network mask to the Management Ethernet interface.
BOOT_USER # interface management ethernet ip address ip_address_with_mask
For example, 10.16.150.106/16.
5. Assign an IP address as the default gateway for the system.
