To Return to Automatic Boot Mode
1. When you are ready to return to automatic boot mode, set switch 6
UP
2. Reboot by selecting
1
,
2
,
3,
or
4
. Rebooting with switch 6 in the
UP
position will cause the router to boot
router software automatically in the order and manner you have specified.
Option 1: Retry Start-up
When in Manual Boot mode, you can reboot the router in the boot procedure order by selecting option
1
,
“Retry start-up”.
The boot procedure order is either one you have specified or the default order. The
default order is to boot from FLASH memory and then the network (if defined). If you wish to boot from the
network and/or alter the boot procedure order, refer to
Option 3: Boot from Network
.
Option 2: Boot from FLASH Memory
If you wish to perform a manual boot from FLASH memory, select
2
from the main boot procedure menu.
The router will attempt to boot from FLASH memory. If unsuccessful, the router will return to manual boot
mode. (When you first receive the router, the router defaults to booting from FLASH during power-up or
automatic reboot.)
Option 3: Boot from Network
First, you have to define permanent network boot parameters using selection
5
. Then, select
3
from the main
boot procedure menu to perform a manual boot from the network. The router will attempt to boot from the
network using the permanent network boot parameters you have specified.
If you have not defined network boot parameters, the router attempts to locate a BOOTP or RARP server on
the network.
BOOTP can be used to supply an IP address, a TFTP Server IP address, and a filename.
RARP is used to obtain an IP address, given the MAC address. The router assumes that the RARP server is
also capable of performing the duties of a TFTP Server and will request the filename
KERNEL.F2K
or the
filename assigned when setting permanent network boot parameters.)
If a BOOTP or RARP server exists and is properly configured with the router’s MAC address, the router will
boot from the network. If unsuccessful, the router will return to manual boot mode.
Option 4: Boot from Specific File
You can temporarily override permanent network boot parameters when performing a network boot. When
the router is in Manual Boot mode, select option
4
, “
boot from specific file”
, from the main boot procedure
menu. Set the network boot parameters; the current default (permanent) parameters are as shown. After
setting the parameters, hit the
return
key and the router will boot from the network using the temporary boot
parameters. If unsuccessful, the router will return to manual boot mode.
Once you have installed router software on a network TFTP server, you can have the router boot across the LAN.
Network booting requires three parameters:
• the boot IP address
