Description
P0914209
Standard 3.00
April 2000
Mechanical shock - unpackaged (servicing)
The LMI, RMI, and LMX circuit packs retain full functionality after being
dropped, as described in TR-EOP-000063(NEBS) under the following
conditions:
From a 30
o
tilt onto all faces and corners
Mechanical shock - transportation bounce
The packaged LMI, RMI, and LMX circuit packs retain full functionality
after bounce testing according to IEC 68-2-29, Test Eb under the following
conditions:
Constant acceleration of 1.2 g
Duration of 30 minutes per surface
Vibration resonance search
The LMI, RMI, and LMX circuit packs retain full functionality after the
vibrational resonance search according to IEC 69-2-6, Test Fc under the
following conditions:
Constant acceleration of 0.1g
Frequency swept manually from 5 Hz to 200 Hz
Repeated for each of the three mutually perpendicular axes
Excessive resonance has been investigated to ensure that no damage or
degradation in performance will occur.
Vibration endurance - operational
The MCR circuit packs retained full functionality while subject to the
vibration endurance test according to IEC 68-206, Test Fc, when configured
in the fourth cube of a Meridian 1 system. The following conditions applied:
Constant acceleration of 0.1g
Frequency swept automatically from 5 Hz to 200 Hz at the rate of one octave
per minute
Repeated for 2 hours on each of the three mutually perpendicular axes
