Converged network adapters 1 Server blades and blade system enclosures (mezzanine adapters) Consider the following points when installing mezzanine adapters in blade servers and system enclosures: • For information on server blades and blade system enclosures that are compatible with adapters, refer to the "Adapters Resources" section of www.brocade.com/adapters. • For information about enclosures, server blades, I/O modules, switch modules, and optional devices that are compatible with this adapter, visit the manufacturer websites for these products. You can also contact your server blades or blade system enclosure marketing representative or authorized reseller. • To support each I/O module that you install in the blade system enclosure, you may also need to install a compatible adapter in each server blade that you want to communicate with the I/O module. Also, the adapter may only support switch modules or blades in specific I/O bays of the enclosure. For additional information, refer to installation and user guides and the interoperability guides provided for the blade server and blade system enclosure. • The Brocade mezzanine adapter is compatible with the following types of modules that install in the supported blade system enclosure: - Pass-through modules - I/O modules - Switch modules NOTE For detailed information about these modules, see the installation and user guides and interoperability guides provided for these modules and the blade system enclosure. • You may be able to install only one mezzanine adapter per server blades. The maximum number of adapters that you can install in the blade system enclosure varies according to the type of enclosure that you are using because each type of enclosure may support a different number of server blades. For additional compatibility information, see the installation, user guides and interoperability guides provided for the blade server and the blade system enclosure.
