Unconnected PoPs

In a multi-PoP network, PoPs must be able to exchange openR packets either on wired or wireless path.
Otherwise, DNs might not receive the IPv6 address allocation and do not onboard to E2E Controller. This is due to when Controller sends the Prefix Allocation message to one of the PoPs and expects the message to reach other PoPs through openR.
In some cases, PoPs might be isolated temporarily, especially while building the network. Figure 237 is an example that shows two unconnected zones.
Figure 237: Unconnected zones due to isolated PoPs

To facilitate such a scenario, a new configuration parameter flags.enable_pop_prefix_broadcast has been introduced in this release. This parameter supports the following Boolean values:

• true – When the value of this parameter is set to true, E2E Controller sends the prefix allocation message to all PoPs individually.
• false -When the value of this parameter is set to false, E2E Controller sends the prefix allocation message to one of the PoPs.
  The default value of this parameter is false (default setting).

Note
You must set this parameter’s flag to false when there is a wired or wireless path between PoPs.
You can modify the flags.enable_pop_prefix_broadcast parameter in the UI of 60 GHz cnWave.
To configure the parameter, perform the following steps:

1. From the landing page of the device UI, navigate to Configuration > E2E Controller.
   The E2E Controller page appears. The flags.enable_pop_prefix_broadcast parameter is available in the E2E Controller page, as shown in Figure 238.
   Figure 238: The flags.enable_pop_prefix_broadcast parameter

2. Modify the value of the parameter.

3. Click Save to save the configuration changes.

Power density exposure limit
Install the radios for the 60 GHz cnWave platform family of wireless solutions to provide and maintain the minimum separation distances from all persons.
The applicable FCC power density exposure limit for RF energy in the 57 – 66 GHz frequency bands is 10 W/m² . For more information, see Human exposure to radio frequency energy.
Calculation of power density
The following calculation is based on the ANSI IEEE C95.1-1991 method, as that provides a worst-case analysis.
Peak power density in the far field of a radio frequency point source is calculated as follows:

Where:
S: power density in W/m²
p: maximum average transmit power capability of the radio, in W
G: total Tx gain as a factor, converted from dB
d: distance from point source, in m
Rearranging terms to solve for distance yields:

Calculated distances and power compliance margins
The following table displays recommended calculated separation distances, for the 60 GHz cnWave™ for Europe the USA and Canada. These are conservative distances that include compliance margins.
Note
At these and greater separation distances, the power density from the RF field is below generally accepted limits for the general population.
Note
60 GHz cnWave™ Platform Family ODU adheres to all applicable EIRP limits for transmit power when operating in MIMO mode. Separation distances and compliance margins include compensation for the antenna configuration of each product.
Table 54: Calculated distances and power compliance margins

Product| Countries| EIRP (dBm)| EIRP (W)| Maximum power density (wirr 2)| Compliance distance (m)
---|---|---|---|---|---
V1000| USA, Canada, EU| 38| 6.3| 10| 0.22
V2000| USA, Canada, EU| 49| 79.4| 10| 0.9
V3000| USA, Canada| 60.5| 1122| 10| 3.0
V3000| EU| 55| 316.2| 10| 1.6
V5000| USA, Canada, EU| 38| 6.3| 10| 0.22

Note
The regulations require that the power used for the calculations is the maximum power in the transmit burst subject to allowance for source-based time-averaging.
The calculations above are based upon platform maximum EIRP and worst case 100% duty cycle.

Figure 246: Saving the log files

Setup issues in IPv4 tunneling
In IPv4 tunneling, if setup issues occurs then perform the below steps:

1. Click Configuration on the left pane, navigate to Network > Basic > Layer 2 Bridge and verify Enable Layer 2 bridge is selected.
2. On the same page under Configuration Management, verify E2E Managed Config is selected.
3. Click Configuration > Nodes > PoP DN > Networking > Layer 2 Bridge and verify Disable Broadcast Flood and Disable IPv6 are disabled.
4. Ensure that PoP DN and DNs are in the same subnet and verify gateway is correct.

Link is not established
If link is not established between the nodes, then verify the below options:

1. Click Configuration on the left panel.

2. Navigate to Nodes > Radio and verify Sector 2 PoP DN and DN’s polarities, frequency and Golay codes.
   Figure 247: The Sector 2 section in the Radio page

3. Select DN > Networking > Ethernet Ports and ensure that specific Ethernet ports are enabled.
   Figure 248: The Ethernet Ports section in the Networking page

4. Click Topology on left pane, go to Nodes and verify Status is Online Initiator.
   Figure 249: Status of nodes in the Topology page

5. Click Statistics on left pane, go to Links and verify RSSI, MCS, TX Power Index.
   Figure 250: Link details in the Statistics page

6. Go to Performance and verify the graphs.
   Figure 251: Graphs in the Performance page

7. Go to Radio and monitor the throughput capacity.
   Figure 252: Monitoring the throughput in the Radio page

8. If internal GPS is used, then verify Configuration > Nodes > Radio > GPS > Force GPS Disable is enabled.
   Figure 253: Verifying the Force GPS Disable check box

PoP not online from E2E/cnMaestro GUI
This usually means that the PoP node is not able to talk to the E2E controller. Ensure that the PoP node has the E2E IPv6 configured properly. Also ensure that there is a route between the E2E controller and the PoP node, if they are not in the same VLAN. Try to ping the E2E from the PoP node (login to ssh).
Link is not coming up

1. Ensure that the two ends of the radios can see each other (clear line of sight in between). If the link is using V3000, ensure that they are properly aligned.
2. Ensure that MAC address of the radios is configured correctly in the E2E Controller.
3. Ensure that GPS sync is not enabled if indoor and ensure that GPS sync is enabled if outdoor.
4. Ensure that both ends of the link has the same software version.
5. Ensure to configure country code on the E2E GUI.
6. Ensure that the two ends of the link use opposite polarity and Golay codes that matches each other.
7. Ensure that the remote ends can reach the E2E Controller – IPv6 configuration (if beamforming is successful but the remote end cannot reach back to the E2E Controller, the E2E Controller/cnMaestro GUI displays link status as up, but the remote radio is offline).
8. If you already have experience setting up a link and you are trying to setup a daisy chain, ensure that there is not any interference caused by the existing link. For example, make sure that the two neighboring link use different Golay code.

Link does not come up after some configuration change
There is a possibility that the remote unit could be in a state that it uses different channel/Golay code/polarity from the near-end unit. Try to factory default the remote radio if possible.
On the E2E Controller/cnMaestro, it shows that the link is up, but the remote radio is NOT online – This means that link is established but the remote end radio cannot reply to the E2E Controller. Check the E2E configuration to make sure that the IPv6 default gateway is configured correctly to allow a route between the E2E controller and the remote radio.
Link is not having expected throughput performance

• Check the radio GUI to ensure that the link is running as the expected MCS mode when user data is passing through.
• Check to ensure that the Ethernet ports of the radios and the testing devices are negotiated to expected data rate (10Gbps).
• Ensure that your testing devices are capable of handling the throughput – run data throughput test by bypassing the radio link.
• Do not use radio internal iperf tool to test throughput.

Factory reset
Recovery mode is used to reset the configuration to the factory settings. To reset the configuration, perform the following steps:

1. Go to Tools menu and click Factory Reset.Pop-up appears. Confirm to reset the device to factory reset
2. Click Yes to reboot.
3. After the reboot, access the device using IP address 169.254.1.1.
   Note
   After factory reset, all configuration set to default mode.
