The NetScreen-5000 Series device supports two module types:

NetScreen-5000 management modules

NetScreen-5000 Secure Port Modules (SPMs)

The following table shows the modules supported by each slot.

Management Modules

The management module provides general-purpose CPU delivery, and contains dedicated 
High Availability (HA) and management interfaces. It handles tasks such as management 
access, session setup and termination, and Internet Key Exchange (IKE) negotiation.

The 5000-M Management Module

The 5000-M is based around a powerful, 600-MHz PowerPC CPU, which assists other 
system elements, primarily with non-flow related tasks. The 5000-M management module 
provides overall management and control of the system. Although it performs system 
management, the primary function of the 5000-M is to support the other modules.

Features of the 5000-M module include:

A management port, for WebUI management sessions or Command Line 
Interface sessions.

A console port, for serial terminal emulation programs such as HyperTerminal.

Two High Availability (HA) ports.

A modem port.

The 5000-M also has port Link and Activity LEDs, CPU utilization indicators, a High 
Availability (HA) LED, an Alarm LED, a Status LED, a Flash LED, and a Power LED. In 
addition, it has a compact flash slot for flash memory card installation.
