Power Supply — P/N 0891000
The Power Supply provides the DC voltage for the Cabinet PCBs and all
telephones connected to the Cabinet Station PCBs.
Each system cabinet must have at least one power supply installed. In order
to determine if a second power supply is required, refer to the load factor
charts located in Section 2 of the Aspire Hardware Manual (P/N 0893100).
Note: One power supply can provide power to 64 analog or digital tele-
phones. If more than 64 telephones are connected to a cabinet, a second
power supply must be used.
! IMPORTANT!
After removing a previously installed NTCPU, handle the PCB, carefully,
from the edges. If certain solder points/resistors are touched on the back of
the PCB, some RAM/temporary memory may be lost (ex: time, date, user-
defined settings, etc.)
