Appendix 1: Configuring the Bootloader
The router must be configured correctly before setting up the bootloader. The service module will not connect to the external network if the router is not configured correctly.
To configure the bootloader, perform the following steps.
Step 1 Enter the following commands from the router CLI:
a. service-module Service-Engine 1/0 reset (wait about 10 seconds after issuing this command)
b. service-module Service-Engine 1/0 session (if the first try fails, repeat this command)
Step 2 Wait for the following prompt:
"Please enter '***' to change boot configuration".
a. Enter "***" to drop the service module into the bootloader.
Step 3 Enter the config command to configure the bootloader:
SE- boot-loader> config
a. Enter these parameters:
IP address —Service module IP address as configured on the host router
Subnet mask— Service module subnet mask as configured on the host router
TFTP server—(Optional) IP address of the TFTP server with the helper image
Gateway—Gateway address as configured in the host router
Default helper-file—(Optional) Filename of the helper image
Note The internal interface is facing the router. The external interface may or may not be present on the service module.
Step 4 Default Boot: disk
Step 5 Default bootloader: secondary
Note Always use the secondary bootloader; primary is only for backup.
Step 6 To enter boot helper type: boot helper
To boot normally from the disk type: boot disk
Tip Use the boot helper to reboot with a helper image if the service module does not boot up with the regular image. See the "Software Recovery Using a Helper Image" section on page 74.
