Updating Functional Images
You can load functional images used by certain hardware controllers in the Cisco ONS 15530. This
section describes the function and maintenance of functional image.

Understanding Functional Images

Functional images provide the low-level operating functionality for various hardware controllers. On
hardware controllers with insystem programmable devices, such as field programmable gate arrays
(FPGAs) and Erasable Programmable Logic Devices (EPLDs), the hardwa re f unct iona l ima ge s can be
reprogrammed independently of loading the system image and without removing the devices from the
controller.
On the Cisco ONS 15530, you can reprogram the functional images on the CPU switch modules,
ROMMON, modules, and line cards.
All new hardware is shipped with functional images preloaded. Loading a different functional image is
required only when upgrading or downgrading functional imag e version s.
Step22 Switch# copy system:running-config tftp: Saves the configuration to a TFTP server. (Optional)
Step23 Switch# configure terminal
Switch(config)#
Enters global configuration mode.
Step24 Switch(config)# redundancy
Switch(config-red)#
Enters redundancy configuration mode.
Step25 Switch(config-red)# maintenance-mode Disables database autosynchronization between the CPU
switch modules and puts the standby CPU switch module
in cold-standby state.
Step26 Switch(config-red)# end
Switch#
Returns to privileged EXEC mode.
Step27 Switch# redundancy reload peer Initiates a reload of the system image on the standby CPU
switch module.
Step28 Switch# show redundancy Displays the CPU switch module redundancy status and
images. Verify that the standby CPU switch module is
running the desired new image and is in either the
NEGOTIATION state or the STANDBY COLD state.
Step29 Switch# redundancy switch-activity force Switches system control over to the standby CPU switch
module by reloading the system image on the active CPU
switch module.
