Wep Keys; Security Settings; Low Power Condition - Cisco Aironet 1130AG Series Hardware Installation Manual

Chapter 6 Troubleshooting

WEP Keys

The WEP key you use to transmit data must be set up exactly the same on your access point and any
wireless devices with which it associates. For example, if you set WEP Key 3 on your client adapter to
0987654321 and select it as the transmit key, you must also set WEP Key 3 on the access point to exactly
the same value. The access point does not need to use Key 3 as its transmit key, however.
Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points for instructions
on setting the access point's WEP keys.

Security Settings

Wireless clients attempting to authenticate with your access point must support the same security options
configured in the access point, such as EAP or LEAP, MAC address authentication, Message Integrity
Check (MIC), WEP key hashing, and 802.1X protocol versions.
If a wireless client is unable to authenticate with your access point, contact the system administrator for
proper security settings in the client adapter and for the client adapter driver and firmware versions that
are compatible with the access point settings.
The access point MAC address that appears on the Status page in the Aironet Client Utility (ACU) is the
Note
MAC address for the access point radio. The MAC address for the access point Ethernet port is printed
on the label on the back of the access point.

Low Power Condition

The access point can be powered from the 48 VDC power module or from an in-line power source. The
access point supports the IEEE 802.3af power standard and the Cisco CDP Power Negotiation protocol for
in-line power sources. The access point requires more power (13 watts) than some legacy in-line power
sources can supply. On power-up if the access point is unable to determine that the power source can
supply sufficient power , the access point automatically enters low power mode and deactivates both
radios to prevent an over-current condition. The access point also activates a Status LED low power error
indication and creates an error log entry (see the
a nd
Warning This product must be connected to an IEC60950 compliant limited power source or a power-over-ethernet
(PoE) IEEE 802.3af compliant power source.
On power up, the access point boots up in low power mode, Cisco IOS software loads and runs, CDP
power negotiation determines if sufficient power is available. If there is sufficient power then the radios
are turned on, otherwise the radios remain disabled.
When the access point is in low power mode, the Cisco IOS show interfaces dot11radio 0 command
produces the following results:
Dot11Radio0 is up, line protocol is down.
