Low Power Condition
Issuing the Cisco IOS Command Using the CLI
Follow these steps to issue the Cisco IOS command for your power scenario:
Step 1 Connect a PC to the access point console port and use a terminal emulator to establish a session with the
access point (refer to the “Connecting to the Access Point Locally” section on page 3-20).
Step 2 From the global configuration mode (refer to the Cisco IOS Software Configuration Guide for Cisco
Aironet Access Points), enter the command below that applies to your power configuration (see
Table 3-2):
• power inline negotiation injector installed
• no power inline negotiation injector
• power inline negotiation prestandard source
• no power inline negotiation prestandard source
Step 3 Enter the write memory command to save the setting to the access point memory.
Step 4 Enter the quit command to exit the terminal session.
