Power Classifications and Deployment

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).

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.

Table 1-1 Powered Device (PD) PoE Power Classifications

		PD Maximum Power
Class	Usage	Range Usage
0	Default	0.44 to 12.95 Watts
1	Optional	0.44 to 3.84 Watts
2	Optional	3.84 to 6.49 Watts
3	Optional	6.49 to 12.95 Watts
4	Not Allowed	Reserved for Future Use

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.
