Consider the following when connecting a PoE switch. The PoE switches are PSE (Power Sourcing Equipment)
that are capable of supplying DC power to attaching powered devices (PD). These devices include VoIP
phones, IP cameras, and wireless access points. The PoE switches can detect and supply power to pre-standard
legacy PoE PD. Due to the PoE legacy support, 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.
To prevent false detection, you should disable PoE on the ports on the PoE switches that are used to connect
to PSEs. You should also first power up a PSE device before connecting it to a PoE switch. When a device
is being falsely detected as a PD, you should disconnect the device from the PoE port and power recycle the
device with AC power before reconnecting its PoE ports.
