NBX 100 The NBX 100 6-Slot Chassis ( Figure 5 ) houses the Network Call Processor
(NCP), which manages call traffic, voice mail, and the Automated
Attendant, and the system disk drive, and the power supply. An NBX 100
system can have one or more chassis, but only one NCP. The top slot has
no access to the backplane. Always cover the top slot with a blank
faceplate. See
“NBX Licensing” on page 56 for more information on the
total number of supported devices.

to the network. The top slot of an NBX 100 6-Slot Chassis has no access
to the backplane. If you are using an NBX 100 6-Slot chassis as an
expansion chassis, always cover the top slot with a blank faceplate.
