This document provides essential steps to set up the Cisco Business 140AC Access Point. It covers physical connection, initial boot-up, and configuration via a web browser or the Cisco Business app. Ensure you have a PoE-enabled switch, router, or injector (802.3af) and a DHCP-enabled router before starting.
Preparing your product
Connect the access point to a PoE LAN port on your router or switch using the provided Ethernet cable. Upon power-up, the LED will cycle through green, amber, and red. This process can take up to 6 minutes. The device is ready for configuration only when the LED is consistently blinking or solid green.
Initial configuration
You can configure the device using the web interface or the Cisco Business app:
- Via Wireless (Web UI): Connect to the SSID 'CiscoBusiness-Setup' using the passphrase 'cisco123'. Launch a browser and navigate to http://ciscobusiness.cisco.
- Setup Wizard: Click 'Start' to launch the wizard, create a username and password, and follow the on-screen instructions.
- Static IP and Mesh: During setup, you may choose to configure a static IP for the Master AP or enable the 'Mesh' option if you intend to add mesh extenders.
After completing the initial settings, the device will reboot. Once finished, log in via https://ciscobusiness.cisco using your credentials to manage the network. Remember to save your configuration by clicking the red disk icon in the UI header.
Mounting
The access point can be mounted on a suspended ceiling, a hard ceiling, a wall, or in the plenum air space above a suspended ceiling. Refer to the Cisco Business Wireless Access Point Administration Guide for detailed mounting instructions.
