This section of the Release Notes Supporting the Cajun P220 and Cajun P550 family of switches 
contains information that is crucial to know before proceeding to install or use the Cajun switch. 
Please review the following release notes before continuing to the Overview section.

Release 4.0.1 embedded software requires a MINIMUM of 16 MB DRAM 

(Dynamic Random Access Memory) to run on a Cajun P550 Layer 2 
supervisor module. BEFORE upgrading, ensure that the switch meets this 
16 MB DRAM requirement. A memory upgrade is not required for a Cajun 
P550 Layer 3 supervisor module, or the Cajun P220.

Release 4.0.1 introduces a new ASCII configuration file format that replaces 

the traditional binary (*.cfg) files used to store and restore saved 
configurations. You must save your binary configuration before upgrading the 
switch to Release 4.0.1 or rebooting the switch for the first time using Release 
4.0.1. For information about saving your binary configuration, refer to the 
“Installation” section of these release notes.

When making configuration changes to the switch, explicitly save changes by 

copying the running configuration to the startup configuration to ensure that 
the changes persist after the switch is restarted.
