6325 Edge Node 3 Reference Information
3.5.9 Safety
Compliance
The principal protection requirements of the low voltage directive 73/23/EEC
are satisfied.
Safety requirements
The requirements of EN 60950-1 “Safety of information technology equip-
ment” is fulfilled. The intended use of the Tellabs 6325 node is on restricted
access locations as defined in EN 60950-1.
The requirements of EN 60825-1: Equipment classification, requirements and
user’s guide, and EN 60825-2: Safety of optical fibre communication systems,
are fulfilled.
An automatic laser shutdown function is provided for the optical STM-1/4/
16 interfaces. This function complies with ITU-T G.664: Optical safety proce-
dures and requirements for optical transport systems.
3.5.10 R&TTE
Compliance
The principal protection requirements of the Radio Equipment and Telecom-
munications Terminal Equipment Directive (R&TTE) 1999/5/EC are satis-
fied.
Requirements
This is verified by performing the tests according to the EMC directive and the
LVD directive, i.e.:
• EN 300 386: Telecommunication Network Equipment, EMC requirements.
Sub clause 7.2 Equipment operating in locations other than telecommuni-
cation centres, see part 5 of this document.
• EN 60950-1: Safety of information technology equipment.
Connections
It is only the optical interfaces of the Tellabs 6325 node, that are intended to be
connected to interfaces of public telecommunications networks.
The safety status of the electrical interfaces of the Tellabs 6325 node is SELV
circuit according to EN 60950-1.
The electrical interfaces of the Tellabs 6325 node must only be connected to
other earthed equipment, and must not be connected directly to outdoor sig-
nal lines.
