Chapter 5 Installation
CAUTION: 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.
NOTE: 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. Before upgrading the switch to Release 4.0.1, review the Installation section of these release notes.
The following memory upgrade kits are available through your local sales representative:
