European Union (EU) Statement
This product is in conformity with the protection requirements of EU Council Direc-
tive 89/336/EEC on the approximation of the laws of the Member States relating to
electromagnetic compatibility. IBM can not accept responsibility for any failure to
satisfy the protection requirements resulting from a non-recommended modification
of the product, including the fitting of non-IBM option cards.
Safety Notices for United Kingdom
1. The IBM 3746 Expansion Unit Model 900 and IBM 3746 Nways Multiprotocol
Controller Model 950 are manufactured according to the International Safety
Standard EN 60950 and as such are approved in the UK under the General
Approval Number NS/G/1234/J/100003 for indirect connection to the public tele-
communication network.
2. The network adapter interfaces housed within the IBM 3746 Expansion Unit
Model 900 and IBM 3746 Nways Multiprotocol Controller Model 950 are
approved separately, each one having its own independent approval number.
These interface adapters, supplied by IBM, do not use or contain excessive
voltages. An excessive voltage is one that exceeds 42.4 V peak ac or 60 V dc.
They interface with the IBM 3746 Expansion Unit Model 900 and IBM 3746
Nways Multiprotocol Controller Model 950 using Safety Extra Low Voltages
(SELV) only. In order to maintain the separate (independent) approval of the
IBM adapters, it is essential that other optional cards, not supplied by IBM, do
not use mains voltages or any other excessive voltages. Seek advice from a
competent engineer before installing other adapters not supplied by IBM.
Electronic Emission Notices
Federal Communications Commission (FCC) Statement
Note: This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates,

uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause
harmful interference, in which case the user will be required to correct the interfer-
ence at his own expense.
Properly shielded and grounded cables and connectors must be used in order to
meet FCC emission limits. IBM is not responsible for any radio or television inter-
ference caused by using other than recommended cables and connectors or by
unauthorized changes or modifications to this equipment. Unauthorized changes or
modifications could void the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
Industry Canada Compliance Statement
This Class A digital apparatus meets all requirements of the Canadian Interference-
Causing Equipment Regulations.
Avis de conformité aux normes d'Industrie Canada
Cet appareil numérique de la classe A respecte toutes les exigences du Règlement
sur le matériel brouilleur du Canada.
Japanese Voluntary Control Council For Interference (VCCI) Statement
This equipment is in the 1st Class category (information equipment to be used in
commercial and/or industrial areas) and conforms to the standards set by the Vol-
untary Control Council for Interference by Information Technology Equipment aimed
at preventing radio interference in commercial and industrial areas.
Consequently, when used in a residential area or in an adjacent area thereto, radio
interference may be caused to radios and TV receivers, and so on.
Read the instructions for correct handling.
Korean Communications Statement
Please note that this device has been approved for business purpose with regard to
electromagnetic interference. If you find this is not suitable for your use, you may
exchange it for a non-business one.
New Zealand Radiocommunications (Radio) Regulations
