DES-3028 DES-3028P DES-3052 DES-3052P  Layer 2 Fast Ethernet Switch CLI Reference Manual 
config poe system 
system. 
Parameters 
power_limit  - The power limit parameter allows the user to 
configure the power budget of whole PoE system. The minimum 
setting is 37 W and the maximum is 370W (depending on the power 
supplier’s capability). Default setting is 370 W. 
power_disconnect_method  -This parameter is used to configure 
the power management disconnection method. When the total 
consumed power exceeds the power budget, the PoE controller 
initiates a port disconnection to prevent overloading the power 
supply. The controller uses one of the following two ways to 
implement the disconnection: 
The default setting is deny_next_port
Restrictions 
User Account Command Level – Administrator and Operator 
g)  deny_next_port - After the power budget has been 
exceeded, the next port attempting to power up is denied, 
regardless of its priority. 
h)  deny_low_priority_port - After the power budget has been 
exceeded, the next port attempting to power up, causes the 
port with the lowest priority to shut down (to allow high-
priority ports to power up). 
Example usage: 
 
To config the PoE System on the Switch: 
DES-3028P:4#config poe system power_limit 185 
power_disconnect_method deny_next_port 
Command: config poe system power_limit 185 
power_disconnect_method deny_next_port 
 
Success. 
 
DES-3028P:4# 
 
config poe ports 
Purpose 
Used to configure the PoE port settings. 
Syntax 
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>]} 
The config poe ports command is used to configure the PoE port 
settings. 
<portlist> -Specifies a range of ports to be configured or all the 
ports. 
all – Specifies that all ports on the Switch will be configured for 
PoE. 
state - Enables or disables the PoE function on the Switch. 
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.  
Description 
Parameters 
• 
critical – Specifying this parameter will nominate these 
ports has having the highest priority for all configured PoE
