Frame Ground Connection
Before connecting VOSS12 power adaptor, follow the instruction below.
For safety purpose, the Frame Earth on the rear part of VOSS12 should be
connected by a pin in the interconnecting plug or socket (local type). This
connection is to protect users and the products from surge, lightening and electric
shock. Thus, it is very important to make sure the Frame Ground is connected
before plug in the power adaptor.
Power Connection
To connect VOSS12 power, follow the instruction below.
Use an AC power socket for VOSS12 adaptor only.
Sharing with the other
devices may cause low power supply which will affect the system operation
.
An AC power which does not provide power at night will affect the system
operation, thus provide power on VOSS12 continuously
.
If all the above conditions are satisfied,
Connect one end of power cable to VOSS12 adaptor.
Connect VOSS12 power connector which is connected to power adaptor to
AC power outlet.
Check DC power input circuit on the rear of VOSS12 and connect the power
adaptor.
VOSS12 does not provide separate power switch so if VOSS12 CD adaptor is
connected power will be supplied on the system immediately.
Normal Operation
Once power is provided to VOSS12, the front of VOSS12 PWR LED is on and
the system will start initializing the system. This initialization takes around
1minute, and all I/O board’s RDY(Ready) LEDs on I/O boards are on and
green colored RDY LED is blinking, then the system initialization is completed.
Now the system is ready to use.
CAUTION
: While connecting telephone lines to FXO board, check whether the
LEDs of connected line ports are on. If the LEDs are not on, check the line status.
