Looking into price list there are two Power Adaptors for Aruba Instant On
R2X20A | Aruba Instant On 12V/30W Power Adaptor |
R2X21A | Aruba Instant On 48V/36W Power Adaptor |
After checking all datasheet for Aruba Instant On it looks that for all AP first Power Adaptor is suitable.
The question is for what is second one PA?
