• The PRE5 module must have the helper image (eboot) stored in the bootflash (bootflash0:), must have no configuration, and

must be set to boot into ROMMON mode. Individual PRE5 modules ship in this state.

• When upgrading from a PRE2 or a PRE4, copy your startup configuration and running configuration to the external USB disks

(disk1: or disk2:) of the PRE5 module.

Note

If you have redundant PREs installed in the Cisco uBR10012 chassis, and you intend to save the startup configuration, the

running configuration, and the new PRE5 image, be sure to save them to the external USB disks on both the primary and the

redundant PRE.

Saving the Startup and Running Configuration Information

When a PRE is removed from the chassis, any local configuration is lost. You must save your configuration information to the TFTP

server or the USB disks before removing the module.

before removing the PRE.

Step 3

Power down the router. All traffic on the router is terminated.

Note

PREs can be hot-swapped. However, removing a PRE terminates all traffic, therefore we recommend that you

power down the router to ensure a successful installation.
