HP E-MSM466 Access Point
The same hardware is (probably) used for the E-MSM430, E-MSM460, and E-MSM466. The MSM430 is a two-stream only device (integral antennas?). The MSM460 is dual-band 3x3:3 capable with integral antenans. The MSM466 is dual-band 3x3:3 device (multi-5GHz capable) with RP-SMA connectors.
"5184-5953", "(C)Copyright 2010 Hewlett-Packard Development Company, L.P.", and "[G]48RNAA0P.SGC" is silkscreened on the board. Wistron NeWeb is the presumed manufacturer.
The wireless modules are silkscreened with "(XB114_030)", "2010/05/31", "4BDNXA07.SGB". This matches with Unex's ( / Wistron NeWeb's) DNXA-H1. Three SiGe SE2595L frontends are used per card.
The CPU may be a Freescale chip (P1020PSE2HPA).
