Troubleshooting Tip 1:

Not all IP cameras and other PDs classify themselves. If a PD fails to classify itself, the switch will default to Class 0 and

reserve a maximum amount of power (15.4W), even if the PD actually consumes less. This may limit or prevent users from

powering PD(s), even though the switch in theory does have sucient power budget.

There is a potential work around that users may consider. Users may log into the DGS-1100-05PD user interface (GUI) and

manually force the power limit to Class 1 or Class 2 for the port(s) connected to the PD(s). This will limit the amount of

power that the switch reserves on each port to 4 watts (if Class 1) or 7 watts (if Class 2).

This workaround should be used with caution, however. Power demands for cameras often change during operation,

such as when IR LEDs illuminate, or when outdoor heaters turn on. If actual power demands exceed the artical threshold

that has been set by the workaround, the camera(s) will malfunction.

Troubleshooting Tip 2:

To ensure the DGS-1100-05PD is properly powered by an 802.3at switch/injector, check the left LED of port 5. It should be

green. If this LED is amber and not green, then the switch is receiving 802.3af power and not 802.3at power.

In such case, it may be necessary to enable LLDP-MED function in the switch/injector that provides the power. Doing so

will ensure that the switch/injector detects the DGS-1100-05PD as an 802.3at device.
