Hardware Description

5.7.1 Introduction

Functioning as the value-added service (VAS) board of the S7700, the Service Process Unit
(SPU) provides service functions such as load balancing, firewalls, Network Address Translation
(NAT), IP Security (IPSec), and NetStream, thus meeting requirements of different application
scenarios for diverse industry networks.
Currently, the SPU supports only one board, namely, VAMPA.

5.7.2 Function and Application

Function
The system transmits the packets to be processed to the SPU. Then the SPU processes the packets
related to the VASs. The SPU is applicable to load balancing, NAT, firewall, IPSec, and
NetSream solutions.
Application
A VAMPA can be installed in any LPU slot of the S7712, S7706, or S7703.

5.7.3 Panel

Currently, the SPU supports only the VAMPA.
The VAMPA is installed horizontally. A serial interface (identified as CON) and an FE electrical
