System Configuration Guidelines 47SystemConfigurationGuidelinesThree kinds of limits govern the number of devices that you can includewhen you configure a SuperStack 3 NBX system or an NBX 100 system:■ Total device limits per system■ Individual device limits on certain devices■ Licensed device limits on certain devicesTotal Device Limits onthe NBX SystemEach NBX system is shipped with a total-device-limit license that controlsthe total number of devices that you can configure on the system:■ Total on the SuperStack 3 NBX — 250 devices (factory default)To add more devices to a 250-device SuperStack 3 NBX system, youcan purchase additional licenses in 125-device or 250-deviceincrements, up to a maximum of 1500 devices. (For the current deviceand license configuration on your system, see NBX NetSet >Operations > Licenses as well as the Usage Report accessible fromthe Licenses screen.)■ Total on the NBX 100 — 200 devices (factory default and maximumdevice limit)For support above 200 devices, you must purchase a SuperStack 3NBX Call Processor.CAUTION: Your configuration must conform to all of these limits:■ The limit imposed by the total system license (explained next)■ The individual limits on certain device types (explained later in thistopic)■ The license requirements for some hardware and softwareWhat Counts Toward the Total Device Limit?The NBX systems count many physical devices and certain softwareapplications as devices toward the total device limit:■ Physical Devices — Each 3Com Telephone, each Analog TerminalAdapter, each channel on a Digital Line Card, and each port on anAnalog Line Card counts as one device. Additional physical devicelimits are listed in Table 5 on page 49.■ Software “Devices” (Applications) — The NBX Media Driverapplication counts as one device, and each installation (client) of thepcXset Soft Telephone application counts as one device.
