[8023-POEP]
I'm documenting some basic issues I found in Draft 2.0.
33.7.2.2 Requested PD Power Value (p.92, line 10) says the Request Power Value is the power at the output of the PSE PI. This can't be true - requested power in the TLV appears to always be PD interface.
Table 33-9 points to 33.2.9.9 for the Max value of Tlim. The only mention of Tlim in 33.2.9.9 (p.52, line 49) points back to Table 33-9 for the Tlim range.
Table 33-6 Association of Class 0 and Class 4 with Pclass (Minimum PSE Power) = Ptype per 33-9 seems to suggest Class 0 could be type 2 and Class 4 could be type 1 .. was this intended ?
References in Table 33-9, Items 5 and 13 to 3.1.4.2 for Icable are off - Icable is defined in 3.1.4, 3.1.4.2 just specifies Type 2 system temperature derating of 15 deg.
33.2.9.1 The branch whereby a PSE can remove power if out of spec on Vport (p. 49, line 47) is not included in Figure 33-9 (PSE State Diagram). So this only works if we assume this to be an Error Condition or if it is somehow related to a "power_not_available" condition.
