Initial Setup Issues
Q: I have installed my LTE AP, how do I configure the AP on Ruckus LTE AP Management environment?
The Management switch powers on the AP via PoE/power adapter and the AP obtains an IP address from the DHCP server. You must ensure that a DHCP server is configured to provide an IP address to the AP, and is reachable by the AP.
After powering on, Ruckus LTE AP seeks management platform environment connectivity. Ensure that this AP is added to the specific Venue and Network is applied to it on the management platform. For information on how to add an AP to a venue, refer to Adding an AP document.
By default, Ruckus LTE AP Management initiates the following actions after an LTE AP connects:
- Checks the LTE AP software build version, and upgrade to most current version.
- Applies basic configuration (venue and network configuration, SAS Provider, and synchronization) to the LTE AP.
- Reports any alarms or events that occurred on the LTE AP.
Q: What is the sequence of AP bootup and various states of LTE AP indicated by LED illumination?
The following is the setup sequence for each AP:
PWR > EMS > SYNC > EPC > LTE
Review the following table to understand the different LTE AP states indicated by LED illumination and its approximate duration in each state along with any recommended corrective actions based on LED patterns observed during the initial AP/venue setup stage.
| LED Label | Time Duration | LED Color/Behavior | Corrective Action |
|---|---|---|---|
| PWR | Until corrective action is executed. | OFF: AP is not powered on. | Check the AP power source. |
Less than 5 minutes. | RED: Boot up in process. The LED remains red if AP does not successfully boot and begin operation. | If longer than 5 minutes, check adequate power is supplied (PoE+/ 802.3at), toggle the power source connection, check cables. If the LED is still RED, contact Ruckus support. | |
Until corrective action is executed | AMBER: AP does not have sufficient Power levels | Check adequate power is provided through appropriate PoE cables. | |
Few minutes. Until corrective action is executed. | Slow-flashing GREEN: AP does not have a routable IP address (IP address has not been allocated from a DHCP server). | If slow-flashing green is non-stop, check the DHCP settings as the LTE AP is unable to obtain an IP address. | |
Perpetual (until default) | SOLID GREEN: AP has booted successfully and obtained a routable IP address. | No action is required. | |
| EMS | Until PWR LED turns Solid Green. | OFF: AP is not being managed by an EMS (Ruckus LTE AP Management). | After PWR LED is in solid green, the EMS LED either startsfast-flashing green autonomously, or solid green immediately. If not, check the reachability of the LTE AP IP to the AP Management. |
| Until IP reachability is resolved for LTE AP IP. | Slow-flashing GREEN: AP is unable to communicate with LTE AP Management/EMS' SecGW. | Check the IP reachability to the Internet and LTE AP Management. Make sure that the AP is accurately created and added to a venue on LTE AP Management. | |
| Usually less than ~ 10-15 minutes. | Fast-flashing GREEN: AP is being managed by the EMS and is receiving a configuration or a firmware update. | Until the time required to download firmware or configuration. Depends on internet connection speed, do NOT unplug or change anything as this might corrupt the Ruckus Cloud LTE software and needs factory reset. | |
| Perpetual. | SOLID GREEN: AP is being managed by the EMS. For example, AP successfully connected to AP management. | EMS-AP connection should be always ON. | |
| EPC | May be up to 60 minutes. | OFF: AP is not configured with the Network (EPC) connectivity information. | Make sure that the network configuration is accurate and a Network is turned ON for the AP Venue. Also, check the PTP status under AP Details. If unknown/link lost EPC connection is not attempted, wait until the PTP sync is acquired which takes up to 60 minutes. |
| ~ few moments after ptp sync obtained AND S1 parameters match else see Corrective Action. | Slow-flashing GREEN: AP is unable to connect to the EPC. | Check if SecGW configuration is accurate (if enabled). Attempting S1 connection to MME but unable connect. Check the reachability or even if reachable, S1 is failing to establish. Check the S1 parameters on network settings. Note that the MME IP, PLMNID, TAC, and Cell ID have to be unique per venue. | |
| Perpetual | SOLID GREEN: AP is connected to the EPC. | ||
| SYNC | Perpetual | OFF: Timing source is VCTXO/standalone. | Stand-alone mode: Removes Timing dependency for operation. No action needed. |
| Until Corrective Action is executed. | Slow-flashing GREEN: Not Timing synced and the AP is not receiving a GPS signal, a macro cell signal (NL) or a PTP signal. | Timing Master: Check the line-of-sight visibility to Timing satellites. Place the AP closer to a window or open sky. Timing Slave: Check the IP reachability between the Timing Slave and the Timing Master. | |
| May be up to ~ 2 hrs. or more; depends on weather conditions and AP placement. | Fast-flashing GREEN: AP is in the process of acquiring sync, but has not yet acquired sync lock. AP is receiving a GPS signal or a PTP signal. | The sync process is dependent on the GPS signal strength and precision so it takes up to 2 hours. Avoid changing anything during this phase. | |
| Perpetual until sync is lost. | GREEN: Time synchronization achieved. | If sync synchronization lost, debug the IP connectivity or any other local issues. | |
| LTE | Perpetual or until corrective action is executed. | OFF: LTE transmitter is disabled. | AP service is set to OFF on LTE AP Management or a Grant is not received from SAS to transmit. If the later is true, check the SAS availability, CBSD Registration parameters (SAS URL, CBSD User ID, and so on) under AP Properties > More. |
| Perpetual until at least one UE registers with AP. | AMBER: LTE transmission is ON, no UEs are attached. | No UE is registered, check UE settings. | |
| Perpetual until all UEs de-register from AP. | SOLID GREEN: LTE transmission is ON and one or more UEs are attached to the cell. | — |
