SCC Power Requirements
and Solutions
Installing new SCC modules in the SC-2345/2350 carrier increases the
power requirements of the SCC system. Depending on the number and
types of modules you are using, the power requirements of an SCC system
can eventually exceed the amount of power available from the SCC-PWR
module. Copy the following worksheets and use them to recalculate the
power requirements of the SCC system when you add new SCC modules.
To calculate the analog and digital power requirements for all the SCC
modules in each SC-2345/2350 carrier, complete the following steps:
1.
Enter the number of modules of each type that you plan to use in
Table C-1,
Number of Modules per Carrier
.
2.
For each module type, multiply
Number of Modules per Carrier
by
Maximum Analog Power Required (mW)
and enter the product in
Analog Power Required by Module Type
.
3.
For each module type, multiply
Number of Modules per Carrier
by
Maximum Digital Power Required (mW)
and enter the product in
Digital Power Required by Module Type
.
4.
In Table C-2, total
Analog Power Required by Module Type
and enter
the sum as
Total Analog Power Required per Carrier
.
5.
In Table C-2, total
Digital Power Required by Module Type
and enter
the sum as
Total Digital Power Required per Carrier
.
6.
Use Table C-3 and the sections that follow to determine which power
option works for your system. The calculated power requirement must
be lower than the available power for each power type.
