SC-2345/2350 Carrier
For the SCC-PWR02 to supply enough power for your SCC configuration
on the SC-2345/2350 carrier, the following two conditions must be true:
P
A
≤
P
AMax
and
P
D
≤
P
DMax
where
P
A
is the total analog power required by your SCC configuration,
in watts;
P
AMax
is the maximum analog power available in watts, from
Table C-3;
P
D
is the total digital power required by your SCC configuration,
in watts; and
P
DMax
is the maximum digital power available in watts, from
Table C-3.
Calculating the Power Available from the SCC-PWR03
The following section discusses the conditions which must be met for the
SCC-PWR03 to supply power to the SCC configuration on the SC carriers.
