Rear Labeling (SFP series)
Serial Number (SN) identifier, Media Access Control (MAC) address identifier, input power
requirements, certification compliance identifiers and various other information are provided on this
rear label.
3.3.5
Input Power
Two DC input power sockets are provided on the rear panel. The front panel
POWER 1
and
2
LEDs are illuminated
green
, respectively:
(SFP series) - when the DC
POWER
switch is depressed
ON
and DC power is available at
both the two rear DC power sockets; or
(BT series) - when DC power is available at both the two rear DC power sockets.
Either
POWER 1
or
2
LED not illuminated when powered, indicates a defective power source and
immediate investigation as to the cause is required to insure redundant power integrity.
Although only one switching AC adapter power supply is required to power the configurable unit,
use of a second independent power source is strongly recommended to assure uninterrupted
monitoring. Furthermore, connecting the second DC input power socket to a different external
power source circuit than the first DC input power source eliminates power as a single point of
failure.
