Introduction

This chapter provides a brief description of new features, minimum hardware and software levels,

and the compatibility requirements for the release of the UltraNet Edge Storage Router - 3000

Series (“UltraNet Edge 3000”).

What’s New With the Release

Environmental concerns and the desire to protect human health, has led the EU (European Union)

to issue the Restriction of Hazardous Substances (RoHS) directive. RoHS eliminates or restricts the

use of lead (Pb) and other hazardous substances in electronic products. To comply with RoHS, a

new Asynchronous Transfer Mode (ATM) card is available with this release. The new card does

not support Packet over SONET (POS) networks, but is otherwise functionally equivalent to the

card that it replaces. Table 1-1 summarizes the differences.

Table 1-1 Differences between Old and New ATM cards
