The AC/DC Power Card is mounted in the rear side of each MODULAR CHASSIS. The AC/DC Power 
card provides power to all circuit cards, which are resided in the MODULAR CHASSIS. 

 

AC power requirements are as follows: 
 
Input Voltage:  85 to 264VAC, 50/60 Hz (Auto sensing 100V/200V selection)

AC/DC Power Supply  
Output:+5 V, 5.5A, -27 V, 3A 

 
UPS or battery backup (with external battery) is available for backup power for AC power failure.  In 
case of battery backup, sealed type battery should be used.  The open type battery is not available 
because of AC/DC power specifications.  

 

10 minutes (Built-in battery) 

12VDC, 0.8AH x 2 

30 minutes (External battery) 

12VDC, 2.2AH x 2 

3 hours (External battery) 

12VDC, 12AH x 2 

 

 
The RGU provides ringing supply to analog SLT (PN-4LCAA is no longer required); however, it cannot 
ring more than 6 analog SLT’s per MODULAR CHASSIS simultaneously. Therefore, the simultaneous 
ringing has to be limited by office data setting.

The cooling FAN is mounted at the right side of each MODULAR CHASSIS.  The FAN should be 
replaced every 4 years in order to ensure the cooling system.
