Enterasys Networks 7S4280-19-SYS - Manual (Page 22)

Overview
1-2 Introduction
The N1-7C111 Chassis
The Enterasys Matrix N1 chassis design provides a single slot for the NAC Controller PEP. The
2S4082‐25 NAC Controller PEP is installed in the 2S4082‐25‐SYS NAC Controller. The 7S4280‐19
NAC Controller PEP is installed in the 7S4280‐19‐SYS NAC Controller.
The NAC Controller PEP installed in the Enterasys Matrix N1 chassis interfaces to the chassis
backplane utilizing the FTM2 connector.
The Enterasys Matrix N1 chassis:
• Allows hot swapping of the NAC Controller PEP,
• Supports two redundant, load‐sharing power supplies, and
• Can be installed as a freestanding unit or installed into a standard 48.26‐centimeter (19‐inch)
rack.
All active components for the N1 chassis are located on the back side of the chassis for increased
safety. All LED indicators are observable from the front of the chassis to aid in monitoring network
operational status and performing maintenance.
The NAC Controller PEP
The NAC Controller PEP is Enterasys’ next generation of enterprise module that deliver high
performance and flexibility to ensure access control along with comprehensive switching, routing,
Quality of Service, security, and traffic containment. The NAC Controller PEP installed in your
Enterasys NAC Controller will be either a 2S4082‐25 or a 7S4280‐19 depending upon the NAC
system. Key NAC Controller PEP features include:
• Proactive security for users, guests and other end systems
• Enforces automated policy based authorization controlling both access and Quality of Service
• Provides a single integrated NAC Controller solution that works in any network regardless of
technology or vendor
• Superior performance and capacity to support more high‐bandwidth and latency sensitive
applications
• 10/100/1000 Base‐TX and 10 Gigabit Ethernet connectivity
• Port‐ and User‐Based Policy and Multilayer Packet Classification that provides granular
control and security for business‐critical applications
• High‐availability with failover for services and management
• Self‐learning configuration modules with increased reliability and fault tolerance that reduces
configuration time and maximizes uptime
• Network‐wide configuration, change, and inventory management that is easier to install,
troubleshoot, and maintain
• Reduced support and maintenance costs, and decreased configuration time
• A two‐port Mini‐GBIC Gigabit Ethernet Uplink Module
Each of the NAC Controller PEP front panel ports can operate in either half‐duplex or full‐duplex
mode of operation. The duplex mode can be determined by either auto‐negotiation or manual
configuration.
The NAC Controller PEP ports can be configured to control traffic by limiting the rate of traffic
accepted into the module and prioritizing traffic to expedite the flow of higher priority traffic
through the module.
