Question 1

It says poe+ (24w) but 60w total / 4 = only 15w per port so is this not full poe+ to all ports?

Accepted Answer

By the tech specs on the manufacturers web site, all 4 ports are PoE+ (802.3at).  You are simply constrained by the overall PoE power budget of 60W total.  This is not misleading by the manufacturer or seller.  Even Cisco corporate 48-port PoE switches that cost signaficantly north of $10,000 are sold as 48-port PoE+ switches with a power budget of 485W.  This just means that you can't use all 4 ports for PoE+ simultaneously due to the power budget.  Very standard at all levels of networking.

Question 2

Is there a safety feature where it won't provide the power to the ethernet cable if the device is too large? like a pc?

Accepted Answer

Yes. 
It will not have POE unless it is required by the device. It will not push power to a laptop or computer if not needed.

Question 3

Does not seem to support "passive" poe. is this correct? please mention this in the description.

Accepted Answer

Passive POE is the exception, not the rule. If a switch is industry-standard 802.3af or 802.3at compliant, it will not support passive POE. This is true for pretty much any/every POE switch you can find: you will not see support for passive POE. Perhaps the only exception I can think of is the Mikrotik PowerBox, and their documentation clearly states that they support passive POE (and not industry standards like 802.3af or 802.3at).

Question 4

Is the uplink port 100 mbps  or 1000mbps?   thanks!
