1.1.2 Introduction to Switching Engines
Switching engines, also known as SRPUs, are the core of the S7500 series, and
include the following models:
z Salience III (LS81SRPG)
z Salience III Plus (LS81SRPG1)
z Salience III Edge (LS81SRPG3)
An SRPU generally has the following functions:
z L2 and L3 data forwarding between LPUs
z Route calculation
z LPU monitoring
z Processing of monitoring signals of components such as the system power and
fans
Salience III series SRPUs provide a high packet forwarding rate and switching capacity.
Each SRPU provides four 1000Base-X SFP ports (only for Salience III and Salience III
Edge) and one hot-swappable CF card port. The CF card stores the log and host
version to facilitate online software upgrade.
