Device Issues

The following section provides details on the typical issues that you might face with devices provisioned and managed in the HPE Aruba Networking Central network and the steps to help troubleshoot these issues.

APs are not seen in the HPE Aruba Networking Central Network

HPE Aruba Networking Central validates device connectivity by the network Web socket connection that the device maintains with HPE Aruba Networking Central. If there is no communication of state information from the device for more than 5 minutes, HPE Aruba Networking Central marks the device as offline and the device is not configurable. You must also add device subscription licenses to enable the AP to appear in the HPE Aruba Networking Central network.

If the AP moves to a new network and the new connected Virtual Controller is not licensed, the AP is not shown in the network. For an AP to show up in HPE Aruba Networking Central, you must make sure that the MAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address and the serial number of the AP is added in the device inventory and also the AP is licensed in the inventory. Even after adding the device inventory, if the AP is not showing up in HPE Aruba Networking Central you must verify if the following ports and URLs Uniform Resource Locator. URL is a global address used for locating web resources on the Internet. are allowed by the firewall Firewall is a network security system used for preventing unauthorized access to or from a private network. at the customer's site:

• TCP Transmission Control Protocol. TCP is a communication protocol that defines the standards for establishing and maintaining network connection for applications to exchange data. Port 443
• TCP Port 80
• UDP User Datagram Protocol. UDP is a part of the TCP/IP family of protocols used for data transfer. UDP is typically used for streaming media. UDP is a stateless protocol, which means it does not acknowledge that the packets being sent have been received. Port 123
• activate.arubanetworks.com
• device.arubanetworks.com
• rcs-m.central.arubanetworks.com (console)
• pool.ntp.org (time server)

For more information on the domain names used by HPE Aruba Networking Central application and devices, see Opening Firewall Ports for Device Communication.

If all the ports and URLs are allowed by the firewall and you are still unable to see the AP in HPE Aruba Networking Central, raise a ticket with the Technical Support.

Devices are Offline in the HPE Aruba Networking Central Network

If there is a network outage or the device looses a web socket connection to HPE Aruba Networking Central at the customer site, the device goes offline and is unable to communicate with HPE Aruba Networking Central. Apart from network issues, there are a few physical issues that could also cause the device to go offline.

• The LEDs on the AP are turned OFF.
• System LED Light Emitting Diode. LED is a semiconductor light source that emits light when an electric current passes through it. lights are blinking in green or red—Depending on the warning and error messages the color of the LED lights change from green to red.
• Bad Ethernet Ethernet is a network protocol for data transmission over LAN. port—If the Ethernet port on the AP has gone bad or the cable itself has some issue.
• Cable falling off—The AP is so heated up and has caused some physical damage. The AP shuts down automatically and reboots again because of the thermal issue.
• PoE Power over Ethernet. PoE is a technology for wired Ethernet LANs to carry electric power required for the device in the data cables. The IEEE 802.3af PoE standard provides up to 15.4 W of power on each port. issue—An AP is powered up either through an adapter or through the Ethernet port. There are two scenarios where an AP might not come up:
  • The Ethernet port does not provide sufficient power to the AP.
  • The Uplink port or PoE port is disabled or not configured correctly.

The Switch Details page will display PoE alerts and the status of the port that is connected to the AP.

To solve these physical issues of a device, you must issue a direct Return Merchandise Authorization (RMA Return Merchandise Authorization. RMA is a part of the product returning process that authorizes users to return a product to the manufacturer or distributor for a refund, replacement, or repair. The customers who want to return a product within its Warranty period contact the manufacturer to initiate the product returning process. The manufacturer or the seller generates an authorization number for the RMA, which is used by the customers, when returning a product to the warehouse.).

Under Standard Warranty or Limited Lifetime Warranty (LLW) hardware RMAs are handled through best effort. Out of warranty and/or expired contract hardware requires Service Renewal prior to an RMA. TAC Technical Assistance Center. only handles defective RMAs under proper entitlement.
