Can an AIR-SAP1552I-A-K9 outdoor AP be converted to run as a lightweight? The part number on the box is AIR-CAP1552I-A-K9 but a show ver on the AP shows it as AIR-SAP1552I-A-K9. It's a little strange that I can't find part number AIR-SAP1552I-A-K9 anywhere on Cisco's website. It's not listed as an orderable part number in the data sheet for 1550s.
