IBM Americas/Far East and IBM Europe/Middle East/ Africa
The pre-delivery/setup responsibilities and procedures for a 3276 with an external
modem, the 3278, the 3279, the 3287, and the 3289 are the same for U.S. installations
and for countries served by IBM A/FE and IBM E/ME/A. The pre-delivery/setup responsi-
bilities and procedures for a 3276 with an integrated modem for A/FE and E/ME/A
countries are the same as those for the U.S., with the following exceptions:
• Connection of the 3276 communication cable to the communication facilities. In
countries where it is permissible, you can connect the 3276 to the communication
facilities. Where the local (country) regulations require a manufacturer's representative
to make the connection, it is recommended that arrangements be made to have an IBM
service representative make the connection. If you do not know whether it is
permissible for you to make this connection, ask your IBM representative for
guidance.
• Communications checks. If communications checks are experienced when attempting
to communicate with the host system, ask your IBM service representative for
guidance.
If you need IBM publications in languages other than English, consult your IBM
representative. The IBM representative can provide information concerning the
availability of translated IBM publications.
Supplemental Information
Safety
Security
The 3276 cluster units are listed by the Underwriters' Laboratory. Exposed hazardous
voltages are not present at the designated customer access areas of the 3274, 3276, 3278,
3279, 3287, and 3289 units.
I
DANGER
Your personnel should be warned not to go beyond the customer access areas, because
hazardous voltages are present within the areas designated for trained personnel only.
Electrical grounding of the 3276 and all the attached units is essential for safety; be sure
that all the facility power receptacles are properly grounded and will accept a grounding
type plug (3-prong or equivalent). If you have any questions about the grounding of
power receptacles, ask an electrician. For information about power cord plugs, power
receptacles, and other safety considerations, refer to IBM 32 70 Information Display
System: Installation Manual~ Physical Planning, GA27-2787.
If the 3276 and the attached units may have access to proprietary records or personnel
records, it is recommended that you implement appropriate safeguards for the security of
the information and the units. IBM makes available some basic functions, but you should
decide which ones to use. In addition to safeguards that you may develop, the Security
Key lock and Magnetic Reader Control features, and the Magnetic Slot Reader accessory,
may be ordered for 3276s, 3278s, and 3279s. In addition, the 3276 Address Keylock
feature is available to enable you to control access to the 3276 SDLC/BSC address
