Figure 10-79. 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.
