In some cases, an offline or degraded OCA may require out-of-band access. There are two ways to enable out-of-band access to an OCA, depending on the hardware revision (HW Rev) or how many OCAs are physically installed at the site.
For OCAs that support it: Specify an IPv6 IPMI configuration
- This optional configuration is supported on the following HW Revisions: 1.60, 1.65, 1.71, 1.72
- The IPv6 IPMI configuration allows the Netflix team to securely access the OCA for remote troubleshooting and management
- In site surveys for new OCA deployments, the IPv6 IPMI configuration is optional
- You can add or change this configuration by using the Partner Portal or the console on the OCA. For more details, see: Updating the network configuration on an OCA
- Note: If you have another OCA in the same site and cannot provision the IPMI configuration, you can also follow the steps below to physically connect the offline OCA to an online OCA. However, it is recommended to specify the IPMI configuration whenever possible for more effective remote management.
For an OCA that does not support or have an IPv6 IPMI configuration: Connect the offline OCA to an online OCA in the same site
You can gain remote access to the offline (unhealthy) OCA by physically connecting it to a nearby OCA that is online (healthy). This article describes how to set up the physical connection between the offline and the online OCA.
To set up out-of-band access:
- Identify an online OCA that is physically located near the offline OCA.
- Obtain a straight-through CAT5/6 network cable long enough to reach both OCAs.
- Find the RJ-45 network ports on the OCAs. They may be hidden behind a metal plate or door, depending on the hardware model.
- Identify the LAN1 port of the online OCA and insert one end of the network cable into it.
Note: Some Global OCAs come with a separate copper connector for the LAN1 port. See Racking and Physical Installation of OCAs for more information.
- Identify the IPMI port of the offline OCA and insert the other end of the network cable into it.
The following image shows an example of the final setup for 2 Flash OCAs.
Note: The locations of the IPMI and LAN1 ports vary according to the type of OCA. Some OCAs have a front panel covering the ports that you will need to remove to access them. See this article for images of these front panels.
