Use of Third-Party Optical Modules

Extreme Networks optical modules are tested to work in all supported Extreme Networks switches. We recommend that all customers use Extreme Networks optical modules in their Extreme Networks switches. Extreme Networks assumes no liability for third-party optical modules. Although Extreme Networks does not block third-party optical modules, we cannot ensure that all third-party optical modules operate properly in all Extreme Networks switches. The customer assumes all risks associated with using third-party optical modules in Extreme Networks switches.

We recommend that customers purchase optical devices that have been authorized and qualified by Extreme Networks, as described on Extreme Networks' then-current price lists.

The ExtremeXOS 15.5 release created a new requirement for customers to purchase a feature license pack named 3rd Party Optics Feature. Like other feature-pack licenses, once you apply the license to a specific switch, the feature is enabled for the life of the switch. Without such a license, switches with 40G and 100G hardware ports that are inserted with unapproved third-party optics modules will have 90 days before the egress traffic on that particular port is automatically limited to 25% of line rate. This license requirement is removed in the ExtremeXOS versions listed above.

Note

The restriction is flagged by show port conf command output, and warning messages are issued when third-party 40G and 100G optical devices are inserted. The restriction is lifted when the 3rd Party Optics Feature license is installed.

The user of the ExtremeXOS 3rd Party Optics Feature is solely responsible for the use of optic devices that comply with applicable standards and safety requirements. The use of non-compliant optic modules may result in damage to the equipment or personal injury. Extreme Networks does not provide any warranty or compliance statement pertaining to any third party non-approved hardware, including unapproved third-party optic modules. See the applicable hardware manual for further details.

When using versions of ExtremeXOS that require a 3rd Party Optics Feature license, the ExtremeXOS 3rd Party Optics Feature has the following caveats and restrictions:

• After reading and interpreting the license information, the system maintains a flag that indicates the presence of the optics license.
• When you insert the optical transceiver after the 3rd Party Optics Feature license is installed, no further action is necessary.
• If the device is an Extreme Networks optical transceiver, no further action is necessary.
• If the optical transceiver is restricted, the system sets a flag, R.
• If the optical transceiver is restricted, the system installs an egress rate limiter of 25% associated with the port.
• If the device is restricted, the system generates a warning EMS message that indicates the restriction.
• If you remove the optical transceiver, the following conditions occur:
  • The system unsets the flag that indicates a restriction in the port.
  • The system removes the egress rate limiter associated with the port, or restores a configured one.
• When you enable a port, the following conditions occur:
  • The system determines if the port is restricted.
  • The system generates a warning message to a console with restricted ports.
  • The system generates a warning EMS message that indicates a restriction.
• When you enable a license, the system reads and interprets the new license information. If it determines the optics license is now active, and it was not active before, the following conditions occur:
  • Sets the "optics license present" flag.
  • Searches the port list for restricted ports.
  • Removes the egress rate limiter associated with the port, or restores a configured one.
