3.4 Front Panel Description
3.4.1
Power
Two switching AC adapter power supplies are provided for each configurable unit. Although only
one power supply is required to power the module, use of a second independent power source is
strongly recommended to assure uninterrupted monitoring. Furthermore, connecting the second
ACinput power socket to a different external power source circuit than the first AC input power
source eliminates power as a single point of failure.
The power barrel sockets are
located on the rear. The
POWER 1
and
2
front panel
LEDs illuminate green when
power is available at both of
the two rear power barrel
sockets indicating power 1
and 2, respectively, are on.
If either LED is not illuminated, it could indicate a defective power source and investigation for
the cause is recommended to insure redundant power integrity.
