Description
Two RP cards (RP0/RP1) are inserted into the front
of the chassis. These cards provide the intelligence
of the system by functioning as the system controller
and providing route processing and chassis
management. The RP cards also monitor system
alarms and control the system fans. The LEDs on the
front panel indicate active alarm conditions.
Four FCs are inserted into the front of the chassis.
The FCs provide the switch fabric for the routing
system and performs the cross-connect function of
the routing system, connecting every LC to each
other. The switch fabric receives ingress user data
from one LC slot and performs the switching
necessary to route the data to the appropriate egress
LC slot.
As many as sixteen LCs can be inserted into the front
of the chassis. These cards provide the physical
interfaces and optical connections for the user data.
The ECUprovides all shelf electrical I/O connectivity
to the active and standby route-processor line cards.
The ECU is located behind the craft panel.
The craft panel can install, configure, monitor, and
troubleshoot the Cisco NCS 4016 chassis applications
at the node and at the network level. The craft panel
is located on top of the ECU.
Two fan trays are inserted into the front of the chassis
at the top and bottom. The top fan tray (behind the
craft panel) cools the top card rack and the bottom
fan tray covers the bottom card rack. Each fan tray
contains six axial fans. The fans pull cooling air
through the chassis from the front to rear.
