Table 3-7 Element Download Commands
Thumbwheel Switches
The thumbwheel switches on the front of the SCC 2020 module are
provided as a measure of last resort for configuring the SCC,
and/or application modules it controls, when terminal access to
the Craft interface is not possible.
It is preferred practice to use the Craft interface, a Telnet session,
or an SNMP manager instead of the thumbwheels.
The SCC 2020 is able to control up to 51 other modules in up to 4
shelves. The thumbwheel switches are only able to address the first
30 slots, thus it is not possible to use thumbwheel commands to
configure a module if it is in the 31st to 52nd slot of a four shelf
node.
