Apply a 1-year L3+ maintenance term to the Infoblox TR-2200-10GE-HW-G-AC hardware configuration. TR-MAIN-2200-10GE-HW-G-AC-21 is a maintenance service order, rather than an appliance order, and associates the annual term with the specific covered 10GE hardware configuration named in the service code. The service is suited to installed environments that need to retain L3+ maintenance for the TR-2200 platform configuration. Its scope matters: the covered product name includes the 10GE hardware designation and G-AC configuration suffix, so the service should be associated with the matching deployed hardware. This avoids applying a maintenance term intended for one appliance configuration to a differently configured system. The distinguishing characteristics of this service are its 1-year duration, L3+ maintenance designation, and hardware-specific coverage. It is not a generic maintenance term for an unspecified Infoblox environment. Use it where the deployed appliance matches the TR-2200-10GE-HW-G-AC designation and where an annual L3+ maintenance period is required. The service does not change the appliance's physical interfaces or operating configuration; it provides the maintenance term associated with the covered hardware.
