Low Power Condition
Inline Power Exception
CDP in-line power negotiation is dependent on similar code being resident in the Cisco switch that is
providing power. However, not every switch supports this CDP power negotiation code. As a work
around for such pre-standard switches the following Cisco IOS CLI command is required:
(config)# [no] power inline negotiation {prestandard source | injector H.H.H}
You can use this Cisco IOS CLI command to inform the access point that the power source is an 802.3af
compliant Cisco switch or that a power injector is being used to supply sufficient power. Refer to
Table 6-2 for information on when to use this special Cisco IOS command.
Caution If the access point receives power through Power-over-Ethernet (PoE), the output current of the power
sourcing equipment (PSE) cannot exceed 400 mA or 1500 V per port, whichever is smaller. The power
source must comply with IEEE802.3af or IEC60950 for limited power sources.
Issuing the Cisco IOS Command
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 3-3).
Step 2 From the Privileged EXEC mode (refer to the “Cisco IOS Command Modes” section on page 5-2), enter
one of these commands that applies to your power configuration (see Table 6-2):
• power inline negotiation injector xxxx.xxxx.xxxx
(where xxxx.xxxx.xxxx is the MAC address of the switch port to which the access point is
connected.
• 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.

AC power module None required
Power injector
1
1. Power injector must be AIR-PWRINJ3 or AIR-PWRINJ-FIB.
For Cisco non-802.3af compliant switches and Cisco switches
without inline power, use this Cisco IOS command:
power inline negotiation injector xxxx.xxxx.xxxx
(where xxxx.xxxx.xxxx is the MAC address of the switch port
to which the access point is connected.
Cisco 802.3af compliant switch

2. If command 2 is not issued when powered only by a Cisco non-802.3af compliant switch, the access point powers up with both radio interfaces
down.
Use this Cisco IOS command:
