Chapter 5 System Power Supply
AC/DC Power Supply
The AC/DC Power card is mounted in the left side of each PIM. The AC/DC Power
card provides power to all circuit cards that are installed in the PIM.
• AC power requirements are as follows:
Input Voltage: 90 to 132 Vrms or 180 to 264 Vrms (selectable by switch) 50/60
Hz
Note:
One power card (PZ-PW121) is included with each PIM. Therefore, it is not
required to place a separate order for a PZ-PW121 except for spare or
replacement.
DC/DC Power Supply
The DC/DC Power card is mounted under the AC/DC Power card and generates -48 V
power, which is used to power ancillary devices such as Wireless and Analog Caller
ID stations.
