Overview of Express5800/320Ma 3.2

GHz, 3.6 GHz, and Dual-Core Systems

The following sections provide an overview of Express5800/320Ma 3.2 GHz, 3.6 GHz,

and Dual-Core systems:

• “System Features” on page 1-2

• “System Components and CRUs” on page 1-3

System Design

The design of Express5800/320Ma 3.2 GHz, 3.6 GHz, and Dual-Core systems

includes the following:

• Fault-tolerant architecture

Critical components are redundant (duplexed). If one duplexed component fails,

the system continues to operate with the redundant component in simplex mode

until you can remove an enclosure or the system from service to replace the failed

component.

• Customer-replaceable units (CRUs), parts that you can replace on-site with

minimal training or tools

Some CRUs are hot-pluggable. You can replace them without interrupting system

operation.

• Fault-hardened drivers that enhance application reliability and availability

• Optional support by the ActiveService Network (ASN)

This support provides remote service and incident management of the system by

NEC Technical Support, or your authorized service representative. Connectivity to

the ASN is through a pair of remote management adapters — Virtual Technician

Modules (VTMs) — and a modem, only through a modem, or over the Internet.
