Recovering from a Failed Start

A system that does not start correctly might be attempting to boot from a corrupted Dell Networking OS image or from a mis-specified location.

In this case, you can restart the system and interrupt the boot process to point the system to another boot location. Use the setenv command, as described in the following steps. For details about the setenv command, its supporting commands, and other commands that can help recover from a failed start, refer to the u-Boot chapter in the Dell Networking OS Command Line Reference Guide .
  1. Power-cycle the chassis (pull the power cord and reinsert it).
  2. Hit any key to abort the boot process. You enter uBoot immediately, the => prompt indicates success. (during bootup) press any key
  3. Assign the new location to the Dell Networking OS image it uses when the system reloads. uBoot mode setenv [primary_image f10boot location | secondary_image f10boot location | default_image f10boot location]
  4. Assign an IP address to the Management Ethernet interface. uBoot mode setenv ipaddre address
  5. Assign an IP address as the default gateway for the system. uBoot mode setenv gatewayip address
  6. Reload the system. uBoot mode reset
