Power over Ethernet (PoE) ports provide power for devices such as IP phones or
wireless access points. PoE is enabled by default. This procedure describes how to
disable and enable PoE and how to set optional parameters.
Procedure
Step 1
Select Devices > Device Management and click Edit () for your threat
defense device. The Interfaces page is
selected by default.
Step 2
Click Edit () for Ethernet1/7 or 1/8 on Firepower 1010 or for any interface from Ethernet 1/5-1/8 on Secure Firewall 1210CP.
Step 3
Click PoE.

Step 4
Check the Enable PoE check box.
PoE is enabled by default.
Step 5
Choose autonegotiation or manual power.
Auto Negotiate Consumption Wattage—Delivers
power automatically to the powered device using a wattage
appropriate to the class of the powered device. The firewall uses
LLDP to further negotiate the correct wattage. When you connect a
device of a certain class, it will be provisioned up to the maximum
for that class in case it ever needs to use more power. For example,
if you add a class 4 device that requests 12.95W, it will be
allocated 30W even if it doesn't currently use all that power. Some
devices can renegotiate power needs. If you know your device needs
less power than is allocated, you can instead set the
Consumption Wattage manually to free up
the power for other devices.
Consumption Wattage—Uncheck the
Auto Negotiate Consumption Wattage check
box to set the manual wattage to manually specify the wattage in
milliwatts, from 4000 to 30000. Use this option if you want to set the watts
manually and disable LLDP negotiation. For manual allocation, the
class will show in show power inline
output as n/a because the class is not used to decide the
power consumption.
View the current PoE status using the show power
inline command.
Step 6
Click OK.
Step 7
Click
Save.
You can now go to Deploy > Deployment and deploy the policy to assigned devices. The changes are not active until you deploy them.
