Measured as Ambient Air Temperature. 300LFM minimum air-flow required. Designed to
meet this temperature specification.
Note:
Temperature rating is exclusive of mSATA module(s). Commercial grade
mSATA modules are normally rated 0°C to 70°C.
Relative Humidity:
5% to 95% Non-condensing (designed to comply)
Storage Temperature:

The power used by the XBRD-9060 board without any mSATA modules
installed is negligible.
mSATA power draws from the ava3.3V on the XVME-6700A. +1.5V is
also available, but usage of this voltage on mSATA modules is not widespread.
