Introduction
Aruba AP-515 factory reset may look straightforward, but sometimes the access point resets successfully and still does not broadcast a Wi-Fi provisioning SSID.
Press and hold the reset button, power on the access point, wait approximately 15 seconds, release the button, and allow the AP to reboot.
That is essentially what the official documentation says, and similar instructions can be found in many online tutorials. HPE Aruba’s installation guide confirms that the AP-515 can be factory-reset while powering up by holding the reset button, connecting DC or PoE power, and releasing the reset button after 15 seconds.
But I recently encountered a different problem.

My Aruba AP-515 appeared to reset successfully, but no Wi-Fi provisioning SSID was broadcasting afterward.
I repeated the reset several times and even tested multiple AP-515 units.
Same result.
After considerable troubleshooting, one change finally got the AP working:
I connected the AP-515’s E0 Ethernet port to my active network and allowed the AP to boot with network connectivity.
After doing this and repeating the reset/startup process, the AP became available for provisioning.
This article documents the complete troubleshooting process — including the important distinction between factory resetting an AP and what the AP does after the reset during provisioning.
My Aruba AP-515 Setup
The access points I was working with had previously been used in an environment with an Aruba controller.
I wanted to repurpose one of these AP-515s for my home network.
My setup was:
5G Internet → Zain 5G CPE Router → Ethernet → Aruba AP-515
The AP-515 was powered separately using a DC adapter rather than receiving PoE from a network switch.
The Aruba 510 Series supports both Ethernet and DC power options. Its E0 interface is a 100/1000/2500Base-T Ethernet port and also supports PoE input.
Everything seemed simple — until I performed the factory reset.
The Aruba AP-515 Reset Procedure I Initially Used
Before repeating the Aruba AP-515 factory reset, I followed the standard reset procedure commonly recommended in online guides:
- Disconnect power from the AP.
- Press and hold the reset button.
- Reconnect power while continuing to hold reset.
- Wait around 15 seconds.
- Release the reset button.
- Wait for the AP to reboot.
And importantly, this procedure is broadly consistent with HPE Aruba’s documentation.
According to the official Aruba 510 Series installation guide, there are actually two ways to factory-reset the AP. During normal operation, the reset button can be held for more than 10 seconds. Alternatively, while the AP is powered off, hold reset, connect DC or PoE power, and release reset after 15 seconds.
So I wasn’t necessarily performing the reset incorrectly.
But I was still missing something.
The Problem: AP Reset, but No SSID Was Broadcasting
After the AP completed its reset and boot sequence, I checked the available wireless networks.
I expected to see an Aruba provisioning network.
But there was no SSID from the AP.
I waited.
I rebooted it.
I performed another Aruba AP-515 factory reset.
Still nothing.
Initially, I suspected that the access point itself might be faulty.
So I tried the same process on two or three Aruba AP-515 units.
The result was essentially the same.
That changed the direction of my troubleshooting.
If several APs showed similar behavior, there was a good chance the issue was related to the boot/provisioning environment rather than failed hardware.
The Missing Piece: E0 Ethernet Uplink During Boot
After further research and testing, I changed the setup.
Instead of powering the AP using only the DC adapter, I connected its E0 Ethernet port to an active network with Internet connectivity while continuing to power the AP through the DC adapter.
In my case:
Zain 5G CPE Router → Ethernet Cable → E0 on Aruba AP-515
The DC adapter continued to power the AP.
I then repeated the reset/startup process while keeping E0 connected.
And this time:
The AP came up correctly and I was able to continue with provisioning.
That Ethernet connection was the key troubleshooting step in my particular environment.
Important: Does Aruba AP-515 Require Internet to Factory Reset?No — this distinction is important.
I initially thought Ethernet/Internet connectivity might be required for the factory reset itself.
After checking HPE Aruba’s official documentation, that would be an inaccurate conclusion.
The official factory-reset procedure does not state that Internet connectivity is required to erase the configuration. The AP can be powered through DC or PoE while the reset procedure is performed.
What happened in my situation appears to concern what happened after the factory reset, when the AP booted and attempted provisioning/discovery.
In other words:
Factory Reset → Boot → Network/Provisioning Discovery → AP Operational State
These are different stages.
And understanding that difference saved me a lot of troubleshooting time.
Why Ethernet Connectivity Can Matter After Reset
This becomes much more interesting when we look at Aruba’s documentation.
An unprovisioned Aruba Instant AP can broadcast a provisioning SSID such as:
SetMeUp-xx:xx:xx
This allows an administrator to connect to the AP and continue provisioning.
However, the AP also performs discovery and provisioning operations during startup.
Aruba documentation explains that APs can interact with provisioning mechanisms including DHCP, DNS, Activate, AirWave, Central and controller discovery depending on software and deployment mode.
This means that:
Factory default does not necessarily mean “immediately broadcast a Wi-Fi network and behave like a consumer access point.”
The AP still has a provisioning process to go through.
Aruba Documentation Actually Covers “SetMeUp SSID Not Broadcast”This was one of the most useful things I found during the research.
Aruba’s own Instant troubleshooting guide has a section specifically for:
“The SetMeUp SSID for AP Provisioning is Not Broadcasted.”
The guide explains that during the initial boot of a factory-default AP, a SetMeUp SSID is normally broadcast for provisioning. But it also acknowledges situations where the SSID may not appear.
Its troubleshooting process includes checking:
1. Whether the AP received a provisioning rule
2. The uplink of the AP
3. Whether another client device can see/connect to the SSID
Aruba also notes that the SetMeUp SSID can be disabled automatically when the AP receives certain provisioning information.
That makes the wired uplink an important part of troubleshooting — even though it isn’t technically a requirement for pressing the factory-reset button.
The Reset Method That Worked in My EnvironmentHere is the complete procedure I used.
Step 1 — Connect E0 to Your Network
Connect an Ethernet cable to the E0 port on the AP-515.
Connect the other end to an active LAN with appropriate DHCP/network connectivity.
For example:
Router / CPE → Ethernet → AP-515 E0
In my case, this was my Zain 5G CPE router.
Step 2 — Power Off the AP
Disconnect the AP’s DC adapter.
If you’re using PoE instead, disconnect its PoE source.
Step 3 — Press and Hold Reset
Use a suitable narrow object to press and hold the reset button.
Step 4 — Restore Power
While continuing to hold the reset button, reconnect power.
For my setup, I reconnected the DC adapter while E0 remained connected to my network.
Step 5 — Release Reset After Approximately 15 Seconds
HPE Aruba’s AP-515 documentation specifies releasing the reset button after 15 seconds when performing the power-up reset procedure.
Don’t simply assume that holding the button longer is better.
Step 6 — Allow the AP to Boot Completely
Now wait.
Enterprise access points can take some time to complete startup, discovery and provisioning processes.
Avoid repeatedly power cycling the AP before it has had an opportunity to finish booting.
Step 7 — Look for the Provisioning SSID
Depending on firmware and deployment state, an unprovisioned Instant AP may advertise a provisioning SSID such as:
SetMeUp-xx:xx:xx
Aruba documents this SSID as part of the manual provisioning process for applicable Instant deployments.

The key difference from my unsuccessful attempts was that E0 was connected to the network while the AP was booting after the factory reset.
Why YouTube Reset Tutorials Can Be Misleading
This experience also highlights a common problem with short technical tutorials.
A video may correctly show:
Hold Reset → Apply Power → Wait 15 Seconds → Release Reset
Technically, that may be enough to explain how to factory reset the hardware.
But it doesn’t necessarily explain what the enterprise AP needs to do afterward.
An Aruba AP can be operating in a controller-based, controller-less/Instant, Central-managed or otherwise provisioned environment depending on its software and deployment history.
Therefore, when an enterprise AP doesn’t broadcast Wi-Fi after a reset, repeatedly pressing the reset button may not address the actual problem.
The better question becomes:
“What is the AP doing after it boots?”
Troubleshooting Aruba AP-515 No SSID After Factory Reset
If you’ve reset an AP-515 but cannot see the expected SSID, check these items before assuming the AP is defective:
- Verify power. Make sure the AP is receiving a suitable power source.
- Confirm the factory reset. Follow the correct reset timing and observe the status LEDs.
- Give the AP enough time to boot. Don’t immediately reset it again.
- Connect E0 to an active LAN. Make sure there is a physical Ethernet link.
- Check DHCP. See whether your router/DHCP server assigns an IP address to the AP.
- Check the previous deployment. Determine whether the AP previously belonged to an Aruba controller or another managed environment.
- Check for
SetMeUpSSID. Applicable unprovisioned Instant APs can use this SSID for provisioning. - Consider provisioning rules. Aruba documents that provisioning information can affect whether the default SetMeUp SSID remains available.
- Check the firmware/deployment mode. Different ArubaOS/Instant/Central deployment states can behave differently.
- Use console access if necessary. If the AP still doesn’t behave as expected, boot/console information can reveal whether it is attempting DHCP, controller discovery or another provisioning process.
What I Learned From This Aruba AP-515 Issue
The biggest lesson wasn’t simply:
“Connect an Ethernet cable.”
It was:
A successful factory reset and successful post-reset provisioning are two different things.
My reset procedure may have been working from the beginning.
What I initially interpreted as a reset failure was more likely a post-reset boot/provisioning problem.
Once I connected E0 to my active network during startup, the behavior changed and I was able to proceed.
That’s a much more useful troubleshooting lesson than repeatedly holding the reset button.
Frequently Asked Questions
How do I factory reset an Aruba AP-515?
You can factory-reset an AP-515 while it is operating by holding the reset button for more than 10 seconds. HPE Aruba also documents a power-up method: with the AP powered off, hold the reset button, connect DC or PoE power while continuing to hold it, and release the button after 15 seconds.
Why is my Aruba AP-515 not broadcasting an SSID after reset?
The AP may have completed the factory reset but still be going through provisioning or discovery. Check the Ethernet uplink, DHCP connectivity, firmware/deployment mode and whether the AP has received a provisioning rule. Aruba’s own troubleshooting documentation recommends checking both provisioning rules and the AP uplink when the default SetMeUp SSID isn’t broadcasting.
Does the AP-515 need an Ethernet cable during factory reset?
The official reset instructions do not specify an active Ethernet/Internet connection as a requirement for performing the factory reset itself.
However, in my real-world troubleshooting case, connecting E0 to an active network during the subsequent boot process solved the no-SSID problem.
What is the Aruba SetMeUp SSID?
Applicable unprovisioned Aruba Instant APs can broadcast a provisioning SSID in the format SetMeUp-xx:xx:xx. It can be used during initial/manual provisioning.
Why can the SetMeUp SSID disappear?
Aruba documentation explains that the default SetMeUp SSID can be disabled when the AP discovers certain controller/provisioning information through mechanisms such as DHCP, DNS or Activate.
Which Ethernet port should I use on an Aruba AP-515?
The AP-515 has E0 and E1 Ethernet interfaces. E0 supports 100/1000/2500Base-T connectivity and PoE input, while E1 supports 100/1000Base-T connectivity.
Conclusion
If your Aruba AP-515 factory reset completes but no SSID appears, don’t immediately assume the reset failed or the access point is defective.
The standard reset procedure may have worked perfectly.
The actual issue may occur during Factory reset the AP correctly, connect E0 to an active LAN, verify DHCP/uplink connectivity, and then observe what happens during a complete boot cycle.
That is exactly what I experienced.
I initially powered my previously deployed AP-515 using a DC adapter, repeatedly performed the Aruba AP-515 factory reset, and waited for a Wi-Fi SSID that never appeared.
After testing multiple units and researching the issue, I connected E0 to my active network during the boot process.
That changed the result and allowed me to proceed with the AP setup.
So if you encounter a similar problem, add this to your troubleshooting checklist:
Factory reset the AP correctly, connect E0 to an active LAN, verify DHCP/uplink connectivity, and then observe what happens during a complete boot cycle.
