Configuration
Verilink NCC 2130 User Manual 3-13
For details on using Node Manager to upgrade an NCC 2130 or the
other modules it controls, refer to the
Node Manager User Manual .
Thumbwheel Switches
The thumbwheel switches on the front of the NCC 2130 module are
provided as a measure of last resort for configuring the NCC,
and/or application modules it controls, when terminal access to
the Craft interface is not possible.
Use the Craft interface or a network management program
whenever possible.
The NCC 2130 is able to control up to 30 modules in up to 4
shelves.
Thumbwheel
Procedure
A four-step procedure is used for each thumbwheel command:
1. Set the thumbwheel to the number, 01 through 30, equal to the
slot number of the module to be optioned. If a node consists
of Multi-line shelves, the first slot in shelf two would be
numbered as 14 and the last slot 26. In a node consisting of all
Dual-line shelves, the first (left-hand) slot of a second shelf is
number 03.
2. Rapidly press the EXE pushbutton twice, as if double-clicking a
mouse. If the NCC 2130 accepts your double-click, the STAT
LED on the selected module will begin to blink green to off. If
the STAT LED does not begin to blink, double click again at a
slightly faster or slower rate. Do not proceed to step 3 until
the STAT LED on the desired module begins to blink. Once the
STAT LED does begin to blink, steps 3 and 4 must be
completed within 60 seconds or the thumbwheel command
procedure will time-out.
3. Set the thumbwheel switches to the command value which is
to be used, per Table 3-7 below.
4. Double-click the EXE pushbutton again. If the NCC 2130
module accepts your double-click, the STAT LED on the
selected module will stop blinking green to off and return to
some other state. If the STAT LED on the module continues to
blink green to off, the NCC 2130 did not accept your double-
click. Try double-clicking again, at a faster or slower rate. If
you are not successful within 60 seconds of the time you
selected the module in step 2, the module will timeout and
return to its normal state. If this happens, start over.
