Boot Mode Transition. Tag 2, Len 1, Data 1/2
This option 43 setting enables or disables the After IP Assignment option which, by default, causes the Boot mode option to use the setting that reflects the server that provided the TCP/IP settings (DHCP Only or BOOTP Only):
•For a data value of 1, the After IP Assignment option is disabled, and the Boot mode option remains in its DHCP & BOOTP setting after successful network assignment. Whenever the Switched Rack PDU restarts, it will request its network assignment first from a BOOTP server, and then, if necessary, from a DHCP server.
See DHCP & BOOTP boot process.
•For a data value of 2, the After IP Assignment option is enabled and the Boot mode option switches to DHCP Only when the management card accepts the DHCP response. Whenever the PDU restarts, it will request its network assignment (TCP/IP settings) from a DHCP server only.
For more information about the After IP Assignment, see Switched Rack PDU settings.
