SecureStack C2 Installation Guide 1-3
The number of PDs that can be supported by the connected SecureStack PoE switch can be
estimated by adding up the maximum power requirement of each connected PD
according to their Power Classification rating (0 through 4).
estimated by adding up the maximum power requirement of each connected PD
according to their Power Classification rating (0 through 4).
The example of a simple configuration shown in
has the 48 Vdc output port
from a C2RPS‐POE connected to a SecureStack PoE switch (such as Enterasys Networks’
C2G124‐48P). The C2RPS‐POE connection provides the 48 Vdc and the power supply
status (indicates if the power supply is okay) to the SecureStack PoE switch, which
manages the 48 Vdc output to the six PDs.

Note: Use the highest power rating of PoE Power Class of each PD to calculate the
maximum wattage. For example, such as 12.95 for a Class 0 device.
