Here are some
changes to Draft 2.0 that I feel are absolutely necessary before we proceed to
adopt it as an official WG draft.
1)
Clause 33.8, Page 101, Line 12-14
The PSE is presently mandated to remove the
power if the PD does not send the first LLDP frame after power-on within 1.25
seconds.
Proposal: Increase 1.25 seconds to 5 minutes. The PSE has three options
- Do nothing and budget
Max Power to PD
- Revert to AF power level
- Remove power
None of these
should be mandated.
2) Clause
33.8, Page 101, Line 21
The PSE shall remove power if loss of communication
persists beyond 2xTTL.
Proposal: Make the PSE behavior optional.
Proposed
Text: Change "PSE shall remove power" to "PSE may optionally remove
power"
3) Figure
33-27, Page 97
The only exit path from the state "LOSS OF COMMUNICATION" is
to remove power.
Proposal: PSE may optionally remove power or wait in that
state until communication is re-established
Thanks
