5.7.5 Attributes of Interfaces on the SPU
This topic describes connector types, attributes, operation modes, and compliance standards of
the interfaces on the panel.
5.7.6 Technical Specifications
This topic describes technical specifications of the SPU, such as board dimensions, panel
dimensions, maximum power consumption, and weight.
5.7.1 Introduction
Functioning as the value-added service (VAS) board of the S9300, 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
The VAMPA can be installed in any LPU slot of the S9312, S9306, and S9303.
5.7.3 Panel
This topic describes the appearance of the SPU, including interfaces, indicators and the colors
and blinking states of interface and board indicators.
Currently, the SPU supports only the VAMPA.
The VAMPA is installed horizontally. A serial interface (identified as CON) and an FE electrical
interface (identified as ETH) are located on the panel. Figure 5-18 shows the panel.
