---

Note Access points with FCC Certification Number (LDK102054) do not support dynamic frequency selection (DFS) on channels 100 to 140 in the US, Canada, and the Philippines. The FCC Certification Number (also called FCC ID number) is shown on the product label on the bottom of the unit.

Special Country Restrictions

Table 3-4 lists special restrictions for wireless operation in some countries.

Table 3-4 Special Country Restrictions for Wireless Operation

Country	Frequency Band (GHz)	Regulatory Domain	Special Limitation and Restrictions
Mexico	2.4	-N	End user must limit 2.4 GHz operation to 2450 to 2483.5 MHz and 36 dBm EIRP1 .
Russian Federation	5	-R	End user must limit 5 GHz operation to 5650 to 5725 MHz.
United States	5	-A	Operation limited to indoor use only from 5150-5250 MHz.

1 EIRP (dBm) = maximum output power (dBm) + antenna gain (dBi)

Changing the Lightweight Access Point Output Power

This section provides instructions for changing the 1130AG series access point output power to comply with the maximum power limits imposed by special regulatory and country restrictions (see the "Special Country Restrictions" section). Follow these instructions to change the output power settings using a controller and your browser:

---

Note Administrator privileges may be required in order to change access point settings.

---

---

Note Regulatory domains are set at the factory and cannot be changed by the user.

---

---

Caution To meet regulatory restrictions, the access point and the external antenna must be professionally installed. The network administration or other IT professional responsible for installing and configuring the unit is a suitable professional installer. Following installation, access to the unit should be password protected by the network administrator to maintain regulatory compliance.

---

The output power on the access points can be changed only using a Cisco wireless LAN controller (2600 series or 4400 series), the controllers on a Cisco Wireless Services Module (WiSM), or using Cisco Wireless Control System (WCS).

---

Note See the Cisco Wireless LAN Controller Configuration Guide for more details on how to to configure your access point using the web-browser interface.

---

Follow these steps to change the access point's output power to meet local regulations using a controller:

---

Step 1 Open your Internet browser. You must use Microsoft Internet Explorer 6.0.2800 or a later release.

Step 2 Enter https://IP address (where IP address is the controller's IP address) in the browser address line and press Enter. A user login screen appears.

Step 3 Enter the username and password and press Enter. The controller's summary page appears.

---

Note The username and password are case-sensitive.

---

Step 4 Click Wireless > 802.11a Radios or 802.11b/g Radios and a list of associated access points displays.

Step 5 Choose the desired access point from the displayed list and click Configure. The radio settings page displays.

Step 6 Scroll down to the Tx Power Level Assignment field, and click Custom.

Custom indicates that the radio output power is manually controlled by the Tx Power Configuration setting field.

Step 7 In the Tx Power Level field, select the appropriate power level setting (1 to 8).

Based on the operating channel, the regulatory domain, and the controller power level setting (1 to 8), the actual transmit power at the access point can be reduced to comply with special regulatory or country restrictions.

Table 3-5 lists the controller power settings and the corresponding output power levels for these two examples:

•2.4 GHz (802.11b/g) operation:

–American regulatory domain and channel 2 using 11 Mbps data rates

•5 GHz (802.11a) operation:

–American regulatory domain and channel 149 using 36 Mbps data rates

Table 3-5 Example of Output Power Levels

Controller Tx Power Settings1	Radio Output Power
	802.11b/g (dBm)	802.11a (dBm)
1 (maximum)	202	173
2	17	14
3	14	11
4	11	8
5	8	5
6	5	2
7	2	-1
8	-1	-

1 The Tx Power Level setting of 1 represents the maximum conducted power setting for the access point. Each subsequent controller power level (such as 2, 3, 4, etc) represents approximately a 3-dBm reduction in transmit power from the previous power level. 2 The maximum output power level obtained from Table 3-2. 3 The maximum output power level obtained from Table 3-3.

Step 8 Click Apply.

Step 9 Close your Internet browser.
