How I configured Aruba AP 505

Last update 26 April 2021

There are different ways to configure this AP. Usually, you can connect to the Console and set up a static IP. However, since a console cable was not available, I had to set up the 24 Aruba APs 505 using a DHCP server I installed on my laptop.

What do you need?

  • Aruba AP 505
  • Ethernet switch that supports PoE
  • Network cables

You can refer to the below steps to configure your Aruba AP 505 or any Aruba AP.

  • Power ON your ethernet switch and connect ONLY one of the AP to the switch for now
  • Assign a static IP address, subnet mask, and default gateway on your laptop.
  • To connect to the AP, I set up a DHCP server on Windows 10 laptop using Tftpd64. You can follow this URL to download
  • From the Tftpd64 interface, select your NIC adapter, then click on Settings below

  • From the DHCP tab, set the IP pool start address, the size of the pool and the subnet mask and click OK
DHCP tab
  • The DHCP interface should look like the below, showing the MAC address, assigned IP address of the devices connected.

  • At this point, your AP should be powered ON with an IP assigned. The assigned IP can be compared with the MAC address to ensure you are connecting to the right device
  • Open a browser, type the IP address of the AP in this format
  • Enter the default username (admin) and password (Serial Number of the AP) into the login page. You will need to change the password the first time you log in
  • It’s advisable to set the static IP address for your AP or you can reserve the IP using the MAC address in production. For this setup, I assigned a static IP.
  • From the dashboard, click on the AP dashboard click on Access Points on the left Pane, then you will find the AP (the MAC address would be displayed)
  • Click on the MAC address and click on the Pen icon to edit the details and assign static IP
  • For the first AP, enable Preferred Master or you can have it disabled. However, once you connect other AP, a cluster is form and the APs will appoint a Master. From the dashboard, you can identify the Preferred Master with the Star
  • Now, you can configure the SSID by clicking on Networks on the left pane àdelete default SSID àcreate a new SSID by clicking the + icon
  • Enter the name of the SSID, select the type – Wired/Wireless, and select the Primary usage – Employee, Voice & Guest.
  • On the next page, select the VLAN assignment of the SSID you are creating
  • On the next page, you will be presented with security options to select
security options
  • And lastly, you will have to decide on the Access type – restricted or unrestricted.
  • For the rest of the AP, simply connect the APs to the Ethernet switch, and wait for it to get discovered. You can set a static IP as well but you do not have to set an SSID as Master IP would broadcast this detail and every other detail to the other APs
