3278 Setup Procedures; 3287 And 3289 Setup Procedures; Replacing Other 3270 Units With 3276S And Attached Units; Replacing A 3271 With One Or More 3276S - IBM 3270 Manual

3278 Setup Procedures
3279 Setup Procedures
After the 3278 is unpacked and placed in its prepared location, the 3278 setup involves:
• Connecting the keyboard cable to the 3278.
• Connecting the device cable(s) (coaxial cable from the control unit) to the 3278 or to
the Switch Control Unit feature.
• Connecting the.magnetic slot reader (if present) to the 3278.
• Plugging in the power cord and switching on the 3278 power.
• Performing the 3278 checkout procedures.
After the 3279
is
unpacked and placed in its prepared location, the 3279 setup involves:
• Connecting the keyboard cable to the 3279.
• Connecting the device cable(s) (coaxial cable from the control unit) to the 3279 or to
the Switch Control Unit feature.
• Connecting the magnetic slot reader (if present) to the 3279.
• Plugging in the power cord and switching on the 3279 power.
• Performing the 3279 checkout procedures.
After completing the 3279 setup procedure, it may be necessary to adjust the color con-
vergence.
3287 and 3289 Setup Procedures
After the 3287 or 3289 is unpacked and placed in its prepared location, the setup
involves:
• Plugging in the power cord and switching power on.
• Performing the 3287 or 3289 checkout procedures.
• Connecting the device cable (coaxial cable from the control unit) to the 3287 or 3289.
Replacing Other 3270 Units with.3276s and Attached Units
Replacing a 3271 with One or More 3276s
Device Addresses
When a 3271 and its attached units (3277s/3284s/3286s/3287s/3288s) are replaced by
one or more 3276s with attached 3278s/3279s/3287s/3289s, special consideration should
be given to planning in order to minimize changes to the existing device addresses, power,
cables, and modems. Replacing a 3284 or a 3286 with a 3287 requires physical planning,
because the 3287 is a table-top unit, whereas the 3284 and the 3286 are floor-standing
units.
Note: The 3277 keyboards, keys, and operator ID card readers cannot be used with the
3276/3278/3279.
Both the 3271 and the 3276 can control a cluster of display/printer units. The 3271 can
control up to 32 attached units; the control unit portion of the 3276 can control up to 8
units (7 attached units and the 3276 Display Station). Both the 3271 and the 3276 have
ports to which the units attach. For problem determination, the 3276 Display Station
must be connected to 3276 port 0.
