Power Classifications and Deployment

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). 

The example of a simple configuration shown in 

Figure 1‐2

 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.

Figure 1-2 Example of a C2RPS-POE Power Configuration

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.
