POE COMMANDS
The xStack DGS-3426P supports Power over Ethernet (PoE) as defined by the IEEE 802.3af specification. Ports 1-24 supply 48
VDC power to PDs over Category 5 or Category 3 UTP Ethernet cables. The xStack DGS-3426P follows the standard PSE pinout
Alternative A, whereby power is sent out over pins 1, 2, 3 and 6. The xStack DGS-3426P works with all D-Link 802.3af capable
devices.
The xStack DGS-3426P includes the following PoE features:
•
•
•
The auto-discovery feature recognizes the connection of a PD (Powered Device) and automatically sends power to it.
The auto-disable feature will occur 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.
The active circuit protection feature automatically disables the port if there is a short. Other ports will remain active.
PDs receive power according to the following classification:
Class Max power used by PD
0 0.44 to 12.95W
1 0.44 to 3.84W
2 3.84 to 6.49W
3 6.49 to 12.95W
PSE provides power according to the following classification:
Class Max power provided by PSE
0 15.4W
1 4.0W
2 7.0W
3 15.4W
The PoE commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following
table.
Command Parameters
config poe system {units [<unitlist> | all]} {power_limit <value 37-370> | power_disconnect_method
[deny_next_port | deny_low_priority_port] management_mode [power_limit |
auto]}
config poe ports [all | <portlist>] {state [enable | disable] | priority [critical | high | low] | power_limit
[class_0 | class_1 | class_2 | class_3 | user_define <value 1000-16800>]}
show poe ports {<portlist>}
show poe system units <unitlist>
Each command is listed in detail in the following sections.
config poe system
Purpose Used to configure the parameters for the whole PoE system.
Syntax
config poe system {units [<unitlist> | all]} {power_limit <value 37-370> |
power_disconnect_method [deny_next_port | deny_low_priority_port]
management_mode [power_limit | auto]}
Description Allows the user to configure the parameters for the whole PoE system.
Parameters units <unitlist>-- Enter the switch in the switch stack for which to configure
the PoE system. This number is based on the unit ID assigned to the switch
in the switch stack. The DGS-3426P is the only switch in this series with PoE
capabilities.
