Cisco Cisco SG200-26P 26-port Gigabit PoE Smart Switch インストールガイド

The switch is to be connected only to PoE networks without 
routing to the outside plant.

If your switch is one of the Power over Ethernet (PoE) models, consider the 
following power requirement:

Consider the following when connecting switches capable of 
supplying PoE:

The PoE models of the switches are PSE (Power Sourcing 
Equipment) that are capable of supplying DC power to 
attaching PD (Powered Devices). These devices include VoIP 
phones, IP cameras, and wireless access points. The PoE 
switches can detect and supply power to pre-standard 
legacy PoE Powered Devices. Due to the support of legacy 
PoE, it is possible that a PoE switch acting as a PSE may 
mistakenly detect and supply power to an attaching PSE, 
including other PoE switches, as a legacy PD. 

Even though PoE switches are PSE, and as such should be 
powered by AC, they could be powered up as a legacy PD 
by another PSE due to false detection. When this happens, 
the PoE switch may not operate properly and may not be 
able to properly supply power to its attaching PDs.
