Chapter 3: Product Specification
3.1 DC Power Supply Module
The DC Power Supply Module specification is described as follows:
•
Input topology:
Four-terminal DC input power connector for each Power Supply Module.
•
Connector type:
Screw barrier connectors.

The AC Power Supply Module specification is described as follows:
•
Input topology:
AC input power connectors for AC-input Power Supply Cage. The lower AC connector connects to the
right hand Power Supply Module as viewed from the rear. The upper AC connector connects to the left
hand Power Supply Module as viewed from the rear.
Note: A second Power Supply Module is a customer installed option.
•
Connector type:
IEC 320 mains input connector.

1.2 Amps @ 200 to 240 VAC
•
Input power:
230 Watts, fully equipped
3.3 Signaling Links
The signaling link specification is described as follows:
•
Signaling links:
The number of signaling links depends on the product variant, which determines the type and number of
SS7 Signaling Boards included. See Section 2.11, “Applicability” on page 14 for more information.
