SCP-PCS822-021-03H
Powering the System
Table 9
summarizes the powering requirements and heat dissipation for the PSC-822 when it is fully populated with
a battery voltage of –48.0 V, and with all CO to RT distances at their maximum DSL reach. The table provides the
average current drawn for a fully populated Field Shelf under these conditions.
The conditions in
Each configuration assumes the use of one Management Unit and 2 MUXs
