On our base station we have PD TPS2372-4RGW with Ls1046A CPU and Aquantia Phy .we have two assembly options:
1 support class 4 up to 30W RCLS1 63.4 ohm and RCLS2 63.4 ohm
- support class 5 up to 45W RCLS1 63.4 ohm and RCLS2 1.21K ohm.
In case that we want to unify assembly and both assemblies will be hardware mounted as 30W ( RCLS1 63.4 ohm and RCLS2 63.4 ohm) do we have
the option to increase power higher than 30W via LLDP protocol.
If yes what are the required hardware changes ?
I guess that TPH , TPL and BT pins should be connected to my host (NXP LS1046A) and add the LLDP protocol to run on the Ls1046A
1.I saw that there is Auto class pin that we left opened since on the past we saw that it limit our power (probably because we don't have LLDP)
2.since we don't know what type of PSE will connect to our units (it can be Cisco or other many switches) do you see any issue with that? Like interoperability problems etc.?
3 Does the LLDP can work whenever I want to provide more power to my PD (By sending message from PD to PSE) or it is limited on the start sessions?
As I understand the mechanism will be as following:
- PSE power up my PD at 30W (class 4) than after while our PD ask from PSE via LLDP to increase power lets say to class 5.is it the correct process?
