2.1 Introduction to LPUs
The modular design of the S700 series provides a reasonable system architecture as
well as standard, mutually independent function modules. Currently, the S7500 series
provide autosensing 10/100/1000 Mbps Ethernet electrical ports, 100 Mbps Ethernet
(single mode/multi-mode) optical ports, GBIC/SFP (single mode/multi-mode) optical
ports, and 10GE optical ports.
The following sections introduce the specifications and performance of LPUs in detail.
