62 | Desktop/Workstation Jumbo Frames Support Normal Ethernet packets are limited to a maximum size of 1548 bytes. Received packets larger than this are normally rejected by the interface card as errors. Jumbo frames support is beneficial for sending large packets, especially when the data contained in these packets either has a time-critical element, or is so large that the time taken to send multiple smaller packets is too great. Jumbo frame packets are normally up to 9000 bytes long. Long-Distance Fiber With the introduction of single-mode fiber adapters, Allied Telesis has extended the size of a fiber network from up to two kilometers over multi-mode fiber, to up to 20 km for Fast Ethernet, and 10 km for Gigabit Ethernet. Advanced Power Management (ACPI) ACPI is part of the environmental control initiative for computers. Allied Telesis adapter cards support ACPI, which places the system in a low power state when it is not receiving or transmitting data.
