Figure 10-83. Hardware Configuration
The Packet Control circuit pack is not administered in the normal manner; there is
no add or remove command associated with it. However the “Packet Bus
Activated?” field on the Maintenance-Related System Parameters Form indicates
if the Packet Control circuit pack is “administered.” If the “Packet Bus Activated?”
field is set to “yes,” a Packet Control circuit pack should be installed in the system,
since the Packet Control circuit pack is required in systems which use the Packet
Bus. If a Packet Control circuit pack is not installed, and the “Packet Bus
Activated?” field is set to “yes,” a major on-board alarm is raised against the
PKT-CTRL MO. This alarm indicates that the Packet Control circuit pack is
“missing.” Refer to the “Maintenance-Related System Parameters Form” section
in Chapter 5, ‘‘Routine Maintenance Procedures’’ for more information on the
“Packet Bus Activated?” field.
Note that the Packet Control circuit pack is listed by the list configuration all or
list configuration control commands only if the Packet Control circuit pack is
physically inserted into its slot and the Packet Bus is activated by setting the
“Packet Bus Activated?” field to “yes” on the Maintenance-Related System
Parameters Form. If the Packet Control circuit pack is physically inserted into its
slot but the Packet Bus is not activated, then the Packet Control circuit pack will
not appear in the output of the list configuration all or list configuration control
commands.
