Low Power Condition Chapter 3 Troubleshooting 1240AG Series Autonomous Access Points Caution If the access point receives power through PoE, the output current of the power sourcing equipment (PSE) cannot exceed 400 mA per port. The power source must comply with IEEE802.3af or IEC60950 for limited power sources. Note After completing your configuration changes, you must remove the serial console cable from the access point.

Chapter 3

Troubleshooting 1240AG Series Autonomous Access Points

Low Power Condition

Caution

If the access point receives power through PoE, the output current of the power sourcing equipment

(PSE) cannot exceed 400 mA per port. The power source must comply with IEEE802.3af or IEC60950

for limited power sources.

Note

After completing your configuration changes, you must remove the serial console cable from the access

point.

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

•
