Jumbo Frame Settings

The Switch supports jumbo frames. Jumbo frames are Ethernet frames with more than 1,518 bytes of payload. The
Switch supports jumbo frames with a maximum frame size of up to 9216 bytes.

PoE

The DES-3528P/DES-3552P Switch supports Power over Ethernet (PoE) as defined by the IEEE 802.3af. Ports 1 to 8
can support PoE up to 30W. (DES-3528P) Ports 1 to 24/(DES-3552P) Ports 1 to 48 can supply about 48 VDC power to
Powered Devices (PDs) over Category 5 or Category 3 UTP Ethernet cables. The DES-3528P/DES-3552P follows the
standard PSE (Power Sourcing Equipment) pinout Alternative A, whereby power is sent out over pins 1, 2, 3 and 6.
The DES-3528P/3552P works with all D-Link 802.3af capable devices.
The DES-3528P/DES-3552P includes the following PoE features:
•
Auto-discovery recognizes the connection of a PD (Powered Device) and automatically sends power to
it.
•
The Auto-disable feature occurs under two conditions: firstly, if the total power consumption exceeds
the system power limit; and secondly, if the per port power consumption exceeds the per port power
limit.
•
Active circuit protection automatically disables the port if there is a short. Other ports will remain active.
Description
Display the port that has been error disabled.
Describe the current running state of the port, whether enabled or disabled.
Display the uplink status of the individual ports, whether enabled or disabled.
Describe the reason why the port has been error-disabled, such as it has become a
shutdown port for storm control.
