# No access to the local unit⁣⁣⁣⁣⁣

Make sure that the connectivity is provided between the control center and the device's installation point. If the access is missing only for the Astrawireless device, further actions must be performed at the device's installation site.

### Indicators <a href="#noaccesstothelocalunit-indicators" id="noaccesstothelocalunit-indicators"></a>

Pay attention to the LED indicators on the device's enclosure.

{% hint style="warning" %}
NOTE

The LED indication on the device can be disabled administratively. Make sure there is no "system no indicator" command in the last saved device configuration. We recommend to save backup configurations to the internal memory of the device and to a folder on your PC. The device can store 8 configuration backups. When saving the current configuration, its previous version is automatically added to the backup list with record number 0. All operations with the device configurations are performed using the "config" command.
{% endhint %}

If the power and Ethernet indicators are off, check the integrity of the power supply, the Ethernet cables and the RJ-45 connectors. Replace the power supply and the cables if necessary.

#### Evolution Base Station Sectors <a href="#noaccesstothelocalunit-evolutionbasestationsectors" id="noaccesstothelocalunit-evolutionbasestationsectors"></a>

LED indicators on the Evolution family base station sectors are located in the the cable glands ports. These indicators help to monitor the device's status during the installation. The correspondence between the state of the indicators and the current device state is shown in the table below.

#### Evolution Su**bscriber Terminals** <a href="#noaccesstothelocalunit-evolutionsubscriberterminals" id="noaccesstothelocalunit-evolutionsubscriberterminals"></a>

Evolution ST devices have a LED indicator set located at the back of each device, displaying the current device state.

<figure><img src="/files/ZZkhRXSeAReXReDo7Ivl" alt=""><figcaption></figcaption></figure>

PWR - power indicators will light red when the device is connected to a power source, yellow when 10/100 Mbps wired connection appears and green when 1000 Mbps wired connection appears. Other indicators are used to perform coarse antenna alignment. The more indicators are on, the better wireless connection is established. The blinking indicator means an intermediate state. The more often the indicator blinks the higher level connection is established.

### Access recovery <a href="#noaccesstothelocalunit-accessrecovery" id="noaccesstothelocalunit-accessrecovery"></a>

If the power indicator is on and there is connection via the Ethernet interface, connect to the device directly as it is shown in the scheme below. Make sure that the IP address of the PC is in the same subnet as the IP address of the device. You can restore the IP address and reset the device to the factory settings using the ERConsole utility.

The factory reset process using the ERConsole is described in the "Emergence Repair Console" article.

### Checking the status of the Ethernet interface <a href="#noaccesstothelocalunit-checkingthestatusoftheethernetinterface" id="noaccesstothelocalunit-checkingthestatusoftheethernetinterface"></a>

#### Wired interface statistics <a href="#noaccesstothelocalunit-wiredinterfacestatistics" id="noaccesstothelocalunit-wiredinterfacestatistics"></a>

**Web interface**

If you were able to access the device by connecting directly, try to determine the possible reason for the unavailability through the network. Pay attention to the wired interface statistics. In order to do this, go to the "[Device status](/astra-wireless-documentation/technical-documentation/astrawireless-evolution-technical-user-manual/operation-and-administration/device-status.md)" section of the web interface and open the "General statistics" window for the Ethernet interface in the "Interface statistics" section. Pay attention to the CRC errors number, as they indicate a violation of the data integrity during the transmission over the wired segment. Also, the problem can be caused by a queue overflow (Retransmit limit) or an inappropriate frame size.

The description of the parameters for a complete diagnostic is available in the "Device status" article.&#x20;

**Command line interface**

If there is no access to the device's web interface, run the "*ifconfig eth0*" command to get statistics via CLI.<br>

The description of the parameters for a complete diagnostic is available in the "Ifconfig command (interfaces configuration)[" article.](https://wiki.infinetwireless.com/pages/viewpage.action?pageId=17605871)

#### **Duplex mode** <a href="#noaccesstothelocalunit-duplexmode" id="noaccesstothelocalunit-duplexmode"></a>

Pay attention to the duplex mode on the network devices connected to the wireless router. This information is available in the the web interface. Proceed to the "Device status" section - "Interface statistics" and open the "General statistic" for the Ethernet interface, or run the "*ifconfig eth0*" command in the command line interface.

<figure><img src="/files/oCtS8QgbEdprlaoOFjL2" alt=""><figcaption></figcaption></figure>

We recommend to set the auto-negotiation mode provided by the Ethernet standard. The problem can occur due to the connection between two devices with different duplex settings. For example, if one device is in auto-negotiation mode and the other is in fixed full duplex mode.

Red value of this parameter in the interface statistics "Mode" column informs that transmission is performed in a half-duplex mode.
