xStack DGS-3400 Series Layer 2 Gigabit Managed Switch CLI Manual
config poe ports
number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3-2:4
specifies all of the ports between switch 1, port 3 and switch 2, port 4 −
in numerical order. Non-contiguous portlist entries are separated by a
comma. (ex: 1:1-1:3,1:7-1:9)
all – Specifies that all ports on the Switch will be configured for PoE.
state - Enables or disables the PoE function on the Switch.
Restrictions
Only administrator-level users can issue this command.
priority - Setting the port priority affects power-up order and shutdown
order. Power-up order: When the Switch powers-up or reboots, the
ports are powered up according to their priority (critical first, then high
and finally low). Shutdown order: When the power limit has been
exceeded, the ports will shut down according to their priority if the
power disconnect method is set to deny_ low_priority_port.
power_limit – Allows the user to configure the per-port power limit. If a
port exceeds its power limit, the PoE system will shut down that port.
The minimum user-defined setting is 1000mW and maximum is
16800mW. The default setting is 15400mW. The user may also choose
to define a power class by which to set the power limit, based on the
PSE table at the beginning of this section.
• class_2 - Choosing this class will set the maximum port limit at
7.0W.
• critical – Specifying this parameter will nominate these ports
has having the highest priority for all configured PoE ports.
These ports will be the first ports to receive power and the last
to disconnect power.
• high – Specifying this parameter will nominate these ports as
having the second highest priority for receiving power and
shutting down power.
• low – Specifying this parameter will nominate these ports as
having the lowest priority for receiving and shutting down
power. These ports will be the first ports to have their power
disconnected if the power_disconnect_method chosen in the
config poe system command is deny_low_priority_port.
• class_0 – Choosing this class will set the maximum port limit at
15.4W.
• class_1 - Choosing this class will set the maximum port limit at
4.0W.
• class_3 - Choosing this class will set the maximum port limit at
15.4.0W.
• user_define – Choosing this parameter will allow the user to
set a power limit between 1000 and 16800mW with a default
value of 15400mW.
Example usage:
To config the Switch’s ports for PoE:
DGS-3400:4#config poe ports 1:1-1:3 state enable priority critical power_limit class_0
Command: config poe ports 1:1-1:3 state enable priority critical power_limit class_0
Power limit has been set to 15400mW(Class 0 PD upper power limit 12.95W + power loss
on cable).
Success.
