Mounting the Cisco WAP551 and WAP561
Wireless-N Access Points
You can place your access point on a desktop, or mount it on a wall or
ceiling.
Placement Tips
• Ambient Temperature—To prevent the access point from overheating,
do not operate it in an area that exceeds an ambient temperature of
104°F (40°C).
•AirFlow—Both side panels have vents which must be unobstructed to
prevent overheating.
• Mechanical Loading—The device should be level, stable, and secure
to prevent it from sliding or shifting out of position.
Wall and Ceiling Mounting
The Cisco WAP551 and WAP561 can be wall or ceiling-mounted. There is
a mounting kit packed with your device. The kit is designed to install your
device to the wall or the ceiling.

Getting Started with the Configuration
To configure the wireless access points, follow these steps to access the
Wizard and then the web-based configuration utility from your computer.
STEP 1Connect the wireless access point to the same network (IP subnet)
as your computer. The factory default IP address configuration of
the access points is DHCP. Make sure your DHCP server is running
and can be reached.
See “Incorrect IP Address” on page 9 for troubleshooting
information, or if you do not have a DHCP server.
STEP 2Locate the IP address of the wireless access point.
a. The wireless access points can be accessed and managed by
Cisco network tools and services including the Cisco FindIT
Network Discovery Utility that enables you to automatically
discover all supported Cisco devices in the same local
network segment as your computer. You can get a snapshot
view of each device or launch the product configuration utility
to view and configure the settings. For more information, see
www.cisco.com/go/findit.
b. The wireless access points are Bonjour-enabled and
automatically broadcast their services and listen for services
being advertised by other Bonjour-enabled devices. If you
have a Bonjour-enabled browser, such as Microsoft Internet
Explorer with a Bonjour plug-in, or the Apple Mac Safari
browser, you can find the wireless access point on your local
network without knowing its IP address.
You can download the complete Bonjour for Internet Explorer
browser from Apple’s Web site by visiting
http://www.apple.com/bonjour/.
c. Locate the IP address assigned by your DHCP server by
accessing your router/DHCP Server; see your DHCP server
instructions for information.
STEP 3Launch a web browser, such as Internet Explorer or Mozilla Firefox.
STEP 4In the Address field enter the default DHCP address and press the
Enter key.
STEP 5Enter the default user name of cisco and password of cisco in the
User Name and Password fields.
STEP 6Click Login. The Wireless Access Point Setup Wizard appears.

STEP 7Follow the Setup Wizard instructions to finish the WAP device
installation. We strongly recommend you use the Setup Wizard for
the first installation.The Setup Wizard turns on the Wi-Fi radio,
allowing you to connect wirelessly. For more advanced
configurations, see the Administration Guide. A link to the
Administration Guide is found in “Where to Go From Here” on
page 11.
Congratulations, you can now start using your wireless access point.
Suggested Next Steps
In case of an error while installing, try the following troubleshooting
procedures:
Troubleshooting
If you cannot display the configuration utility, you can test the ability of the
computer to communicate with the device by using ping. To use ping on a
computer running Windows:
STEP 1Verify that the Cisco WAP551 and WAP561 is powered on and the
lights indicate the appropriate links.
STEP 2Locate the device’s IP address. While there are different ways to
locate your device’s IP address, this procedure uses Cisco FindIT.
a. If you have previously downloaded Cisco FindIT, open Internet
Explorer and launch Cisco FindIT. For more information on
downloading Cisco FindIT, see www.cisco.com/go/findit.
b. In the Cisco FindIT display, place your mouse over the device’s
name. The device IP address is displayed along with other
device information.
STEP 3Open a command window by using Start > Run and enter cmd.
STEP 4At the Command window prompt enter ping and the device IP
address. In this example, we pinged 192.0.2.10.
If successful, you should get a reply similar to the following:
Pinging 192.0.2.10 with 32 bytes of data:
Reply from 192.0.2.10: bytes=32 time<1ms TTL=128

If it fails, you should get a reply similar to the following:
Pinging 192.0.2.10 with 32 bytes of data:
Request timed out.
Possible Cause of Failure
Devices Can’t Connect using Wi-Fi
•Complete the Setup Wizard. The Wi-Fi radio on the device is turned off
by default, and the Setup Wizard activates it. For users who do not wish
to use the Setup Wizard, log into the device using a Category 5e
Ethernet cable, and activate the Wi-Fi radio manually. See the
Administration Guide for details on activating the Wi-Fi radio.
No Power
•Power up the switch and your computer if they are turned off.
•Make sure your PoE switch is powered on and the lights indicate that
you have a link. See “Verifying the Hardware Installation” on page 6.
•Verify that the devices on your network are not plugged into a
switchable outlet.
Bad Ethernet Connection
•Check the state of the indicator lights. See “Verifying the Hardware
Installation” on page 6.
•Check the Ethernet cable to ensure that it is firmly connected to your
devices. Devices connected by the Ethernet cable can include the WAP
device, and routers, any switches, and your computer.
•Verify the connected switch has auto-negotiation enabled. The access
point and the switch need the same negotiation parameters set.
Bad Image
After a new firmware installation, if the Power light is flashing quickly,
contact system support; see “Where to Go From Here” on page 11.
Incorrect IP Address
The most likely cause of connectivity failure is an incorrect IP address. The
Web browser may be pointed to the wrong IP address, or your computer
may be configured with an IP address that is not in the same subnet as the
device.

10 Cisco WAP551 and WAP561 Wireless-N Access Points
Because the factory default IP address configuration is DHCP, make sure
that your DHCP server is running and can be reached. You may need to
disconnect and reconnect the devices for them to discover their new IP
addresses from the DHCP server. You can then query the DHCP server for
the new IP address. See Step 2 of “Getting Started with the
Configuration” on page 7 for more information on how to find the DHCP
address.
If the wireless access points do not receive a DHCP response (there is no
DHCP server on your network) after 60 seconds, the access points will
fallback to the following default static IP address: 192.168.1.245 and a
default mask of 255.255.255.0. To reach that IP address, be sure that your
computer is on the 192.168.1.xxx network.
Rebooting the Devices or Returning them
to their Factory Default Settings
To reboot your device:
•Unplug your Ethernet connection for three seconds and plug it back in.
or
•With the power on, press the Reset button with an opened paperclip
for less than three seconds, or until the lights go off.
– When all the lights go off, release the Reset button.
– Release the Reset button as soon as the lights go off, or you will
restore the device to factory default settings and lose your
configurations.
To reset the device to factory default settings:
•To restore the device to the factory default settings, with the power on,
press-and-hold the Reset button with an opened paperclip for more
than 10 seconds.
– All of the lights will go off.
