|---|---|---|---|
| Physical reset button | 1. Locate the reset button＜br＞2. Press and hold for 10 seconds＜br＞3. Release when LED blinks | Quick and easy | Requires physical access to AP |
| CLI command | 1. Access AP via SSH or console＜br＞2. Enter ‘write erase all’＜br＞3. Confirm and reboot | Can be done remotely | Requires CLI access and knowledge |
Updating firmware
Outdated firmware can often lead to AP termination issues. Keeping your Aruba APs up-to-date is crucial for optimal performance and stability. Follow these steps to update the firmware:
- Download the latest firmware from Aruba’s support portal
- Access your Aruba controller or Instant interface
- Navigate to the firmware update section
