For the service processor safety notices refer to Appendix A, “Safety
Information” on page A-1
For 3745 all Models and 3746 Models 9X0 safety notices refer to IBM 3745
Communication Controller All Models, IBM 3746 Expansion Unit Model 900, IBM
3746 Nways Multiprotocol Controller Model 950, Safety Information, GA33-0400
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
telecommunication 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.
Service Inspection Procedures
The Service Inspection Procedures help service personnel check whether the
