6.2.2 Configuring the PoE Parameters Using the Profile
Follow these steps to configure the PoE profile:
Step 1 configure
Enter global configuration mode.
Step 2 power inline consumption
power-limit
Specify the maximum power the PoE switch can supply globally.
power-limit
: Specify the maximum power the PoE switch can supply. For T1600G-52PS, it
ranges from 1.0–384.0 W, and the default value is 384.0 W. For TL-SG2428P, it ranges from
1.0–250.0 W, and the default value is 250.0 W.
Step 3 power profile
name
[ supply { enable | disable } [ priority { low | middle | high } [ consumption {
power-limit
| auto | class1 | class2 | class3 | class4 } ] ] ]
Create a PoE profile for the switch. In a profile, the PoE status, PoE priority and power limit
are configured. You can bind a profile to the corresponding port to quickly configure the PoE
function.
name
: Specify a name for the PoE profile. It ranges from 1 to 16 characters. If the name
contains spaces, enclose the name in double quotes.
enable | disable: Specify the PoE status for the profile. By default, it is enable.
low | middle | high: Select the priority level for the profile. When the supply power exceeds the
system power limit, the switch will power off PDs on low-priority ports to ensure stable running
of other PDs.
power-limit | auto | class1 | class2 | class3 | class4: Select or enter the maximum power the
corresponding port can supply. The following options are provided: Auto represents that the
switch will assign a value of maximum power automatically. Class1 represents 4W, Class2
represents 7W, Class3 represents 15.4W and Class4 represents 30W or you can enter a value
manually. The value ranges from 1 to 300. It is in the unit of 0.1 watt. For instance, if you want to
configure the maximum power as 5W, you should enter 50.

Enter Interface Configuration mode.
port
: Specify the Ethernet port number, for example 1/0/1.
port-list:
Specify the list of Ethernet ports, for example 1/0/1-3, 1/0/5.
