SNMP V3 implementations. This is an
alphanumeric string used to identify the
SNMP engine on the Switch.

PoE
This function can only be configured when stacking with the xStack
Ethernet (PoE) as defined by the IEEE 802.3af. Ports 1-24 can supply about 48 VDC power to Powered Devices (PDs) over
Category 5 or Category 5E UTP Ethernet cables. The DGS-3426P follows the standard PSE (Power Sourcing Equipment) pinout
Alternative A, whereby power is sent out over pins 1, 2, 3 and 6. The DGS-3426P works with all D-Link 802.3af capable devices.
The DGS-3426P 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: first, if the total power consumption exceeds the system power limit; and
second, 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.
Based on 802.3af/at PDs receive power according to the following classification
Class
Maximum power available to PD
0
12.95W
1
3.84W
2
6.49W
3
12.95W
To configure the PoE features, click Administration > PoE. The PoE System Settings window is used to assign a power limit
and power disconnect method for the whole PoE system. To configure the Power Limit for the PoE system, enter a value between
37W and 370W for the DGS-3426P in the Power Limit field. The default setting is 370W. When the total consumed power
exceeds the power limit, the PoE controller (located in the PSE) disconnects the power to prevent overloading the power supply.
