Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power
sources. If one power source fails, the other live source acts as a backup,
and automatically supplies all of power needs.
Rotary Switch Settings
When power is restored to a bypass unit and its
associated Ethernet switch, there is still a potential
network failure. This is because Ethernet switches
typicall
y need several seconds to boot up, while the
bypass unit will boot up in just a few milliseconds.
Thus, the Ethernet switch will still be booting up when
the bypass unit begins sending packets to process. The OBU-102 has a
rotary switch that can be used t
o specify a period of time to delay sending
new packets after power is restored, to ensure that the Ethernet switch
will be fully active and ready to receive packets at the time that the
OBU
-102 begins sending them. The rotary switch has 10 steps, marked
f
rom 0 to 9. Each step represents a 5 second delay, so the user can set a
delay of 0 to 45 seconds using the rotary switch, depending on the boot
time of the connected Ethernet switch.
LED Indicators
The front panel contains several LED indicators. The function of each LED
is described in the table below.
