Warning

 

The  AC  Power  Supply  switches  must  be  accessible  at  all 
times, because they serve as the main disconnecting device. 

IN THIS REDUNDANT POWERED SYSTEM BOTH AC 
POWER SUPPLIES MUST BE OFF/DISCONNECTED TO 
POWER DOWN THE UNIT.

 

4.2 Installation Steps Overview 

1.

 

Before  installing  the  equipment,  please  read  this  manual  carefully  and  install  the 
equipment  according  to  the  manual.   

Note: 

For  damage  caused  by  installation  not 

being  completed  according  to  the  manual,  Z-Band  Technologies,  LLC.  cannot  be 
responsible and cannot supply free warranty service or free replacements. 

2.

 

Remove the device from the box; bolt it to the rack and ground reliably. (The grounding 
resistance must be < 4Ω).    See section 4.3 for details. 

3.

 

Use  the  digital  multimeter  to  check  the  AC  supply  voltage,  make  sure  the  supply 
voltage complies with the requirements and the power supply switches are in the “OFF” 
position. Then connect the power supplies AC power cords. 

4.

 

Attach the coaxial cable and input the RF signal, turn the power supplies on and observe 
the  front  panel  LED  status.  After  the  LED  working  status  indicator  turns  green,  the 
device is working normally. Turn ON the Laser Switch then press the ENTER button 
on the front panel to check the operating parameters. 

5.

 

Power down the entire unit.   

6.

 

Connect the optical power meter to the optical signal output end by an optical fiber test 
jumper.    Power up the unit, turn on the laser, then measure the optical output power. 
Confirm the measured optical output power and the displayed power are the same and 
have  reached  the  nominal  value.  (Confirm  the  optical  power  meter  is  on  1310nm 
wavelength test position; the optical fiber test jumper is the correct connectorized one, 
SC/APC, and the connector and jumper surface has no dirt, contamination, etc). Power 
down the unit and then remove the optical fiber test jumper and optical power meter; 
connect the device to the network (see section 4.3.3). The device has then completed 
initial installation and debugging.
