Are these AP-93s or IAP-93s (check part number on the sticker on the APs)? The AP-93s require a hardware controller to operate and the IAP-93s run Aruba Instant OS. If they are AP-93s....without a controller, you cannot use them. If they are IAP-93s, you can reset them (using the pin hole on the bottom). This will factory default the IAP. However, in order to update the code, you'd need to pay for support.
