The Open-E Data Storage Server documentation [Manual (Ver. 5.00 up49) November 19, 2008] has this to say about SSH access.

The default port is 22222 for security reasons, seeing as high-number ports are invisible to port scanners. You can change the setting only to a port within the 1024-65535 range.

(And painting your doors the same color as your the rest of your house will make them invisible to burglars.)
