Product Reclamation and Recycling Program
Juniper Networks is committed to environmentally responsible behavior. As part of
this commitment, we continually work to comply with environmental standards such
as the European Union's Waste Electrical and Electronic Equipment (WEEE) Directive
and Restriction of Hazardous Substances (RoHS) Directive.
These directives and other similar regulations from countries outside the European
Union regulate electronic waste management and the reduction or elimination of
specific hazardous materials in electronic products. The WEEE Directive requires
electrical and electronics manufacturers to provide mechanisms for the recycling
and reuse of their products. The RoHS Directive restricts the use of certain substances
that are commonly found in electronic products today. Restricted substances include
heavy metals, including lead, and polybrominated materials. The RoHS Directive,
with some exemptions, applies to all electrical and electronic equipment.

Specification for User-Network Interfaces Including DS1/ATM (1995)
Ensure that power cables deliver sufficient power to the system.
Attach laser fiber connectors only to Class 1 laser devices in accordance with
IEC 60825-1, Safety of Laser Products - Part 1.
Route cables so that they do not restrict ventilation or airflow.
Route cables so that modules and field-replaceable units are easily accessible.
Route cables in a logical direction to prevent loss of connectivity to other
equipment in the rack, associated equipment in adjacent racks, or to the backbone
network.
Consider using cable-management brackets to keep network cables untangled
and orderly and to prevent cables from hindering access to other slots.
For specifications on cables for line modules, see the E120 and E320 Module
Guide.
