Updating Functional Images
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 hardware functional images 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 image versions.
Step 22
Switch# copy system:running-config tftp: Saves the configuration to a TFTP server. (Optional)
Step 23
Switch# configure terminal
Switch(config)#
Enters global configuration mode.
Step 24
Switch(config)# redundancy
Switch(config-red)#
Enters redundancy configuration mode.
Step 25
Switch(config-red)# maintenance-mode Disables database autosynchronization between the CPU
switch modules and puts the standby CPU switch module
in cold-standby state.
Step 26
Switch(config-red)# end
Switch#
Returns to privileged EXEC mode.
Step 27
Switch# redundancy reload peer Initiates a reload of the system image on the standby CPU
switch module.
Step 28
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.
Step 29
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.
