DGS-1510/ME Series Metro Ethernet Switch CLI Reference Guide
disable - Specifies that the legacy PDs detection status will be disabled.
Restrictions
Only Administrators, Operators and Power-Users can issue this command.
Example
To config PoE system-wise was setting:
DGS-1510-28XMP/ME:admin# config poe system power_limit 150 power_disconnect_method
deny_low_priority_port
Command: config poe system power_limit 150 power_disconnect_method deny_low_priority_port
Success.
DGS-1510-28XMP/ME:admin#
56-2 config poe ports
Description
This command is used to configure the PoE port settings.
Based on 802.3af, there are 5 kinds of PD classes, class 0, class 1, class 2, and class 3. The power consumption
ranges for them are 0.44~12.95W, 0.44~3.84W, 3.84~6.49W, 6.49~12.95W, and 12.95~ 29.5W, respectively.
The five pre-defined settings are for users' convenience: The following is the power limit applied to the port for
these four classes. For each class, the power limit is a little more than the power consumption range for the class.
This takes the factor of the power loss on cable into account. Thus, the following are the typical values defined by
the chip vendor.
Class 0: 15400mW
Class 1: 4000mW
Class 2: 7000mW
Class 3: 15400mW
Other than these four pre-defined settings, users can directly specify any value that the chip supported, Normally,
the minimum setting is 1000mW, and the maximum setting is 15400mW for 802.3af and >=35000mW for 802.3at.
NOTE: If the switch fails to supply power to the Powered Device (PD) that supports the IEEE 802.3at
standard,
1. Check if the PD connected to the port supports the IEEE 802.3at standard.
2. Manually configure the corresponding port's power limit value to 30 Watts using the config poe
ports [all | <portlist>] power_limit user_define 30000 command.
Format
config poe ports [all | <portlist>] { state [enable | disable] | [time_range <range_name 32> |
clear_time_range] | priority [critical | high | low] | power_limit [class_0 | class_1 | class_2 | class_3 |
user_define <value 1000-35000>]}
