Known Issues

The SG210-5 is not supported on SGOS 6.2 or higher because this release provides new features and capabilities that require more system resources than available on the SG210-5. (The 210-10 and 210-25 are supported on SGOS 6.2.) The SG210-5 continues to be supported on the SGOS 6.1.x releases. Please contact your sales teams for upgrade options.
