Line 1 shows coaxial port addresses (0-11). In this
example the 3274 is configured for 12 devices (8 Cate-
gory
A
displays and 4 Category B printers). Category A
devices are always shown first. Printer and Category B
devices are then shown separated by two spaces.
Line 2 shows the status of each device, where:
1
=
device powered on
o =
device recognized as powered off
=
device recognized as disabled because of control-
unit-detected errors
x
=
unassigned port (Note 1)
Line
3
shows the type of device attached, where:
d
=
display
p
=
printer
I
=

=
display terminal (3290)
Line 4 shows a summary of coaxial errors, where:
= no errors
= 1-10 errors
I
= 10-20
errors
*
= 20
or more errors
Line 5 shows a summary of device errors, where:
= no errors
= 1-10
errors
I
= 10-20 errors
*
= 20
or more errors
Line 6 shows a summary of sessions bound (this line will
appear only for SNA attachments), where:
+
= session bound
Blank
=
no session bound
Line 7 shows a display of dialed (X.21 switched only),
where:
##XXXX (up to 32 characters) dialed number entered
by the keyboard
## - - - - 0000
=
direct call
## - - - - = incoming call
2-10
line 8 shows a summary of 3274 checks:

1. Customized with individual port addressing. Allows
unassigned (unused) physical port locations between
used coaxial port locations. Applies to configuration
Support D.
2. When 3290 displays are attached, the Category B
adapters are not installed.
f. Test /B Device Address Assignment Table (Model 51 C)
If individual port addressing was used during
customization, the physical port and logical device
addresses can be displayed using the following /B Test.
Refer to Figures 2-7,2-8, and 2-9.
Do the following at any display except a 3290:
(1) While holding the ALT key, press the Test Request
key.
(2) Key in /B.
(3) Press the Enter key. The minus function (x--F) is
r.eturned if the display does not have a large enough
screen size.
(4) To exit the test mode, press and hold the ALT key
and press the Test key.
The format will be displayed as shown in Figure 2-8 or
2-9.
If this step did not fix your problem or it did not
apply, go to Step 6.
Notes:
1. The address table is displayed if the individual port
assignment table was used during customization with
Configuration Support D.
2. If customization was performed using sequential port
addressing (sequence number 112), the /B Test will not
run.
3. Using individual port addressing automatically assigns
the device logical addresses and allows unassigned
(unused) physical port locations between used coaxial
port locations.
