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.

Safety Notices For
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 Nways Multiprotocol Controller Model 900 is manufactured
according to the International Safety Standard EN 60950 and as such is
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 Nways Multipro-
tocol Controller Model 900 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 Nways
Multiprotocol Controller Model 900 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 com-
petent engineer before installing other adapters not supplied by IBM.
Service Inspection Procedures
The Service Inspection Procedures help service personnel check whether the 3745
conforms to IBM safety criteria. They have to be used each time the 3745 safety is
suspected. The Service Inspection Procedures section is located at the beginning
of the 3745 Communication Controller Models 210 to 61A Maintenance Information
Procedures , SY33-2054. The 3745 areas and functions checked through service
inspection procedures are:
1. External covers
2. Safety labels
3. Safety covers and shields
4. Grounding
5. Circuit breaker and protector rating
6. Input power voltage
