Description
Component
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.
route processor cards (RPs)
Four FCs are inserted into the bottom 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.
fabric cards (FCs)
As many as nine LCs can be inserted into the front
of the chassis. These cards provide the physical
interfaces and optical connections for the user data.
line cards (LCs)
The ECU provides all shelf electrical I/O connectivity
to the active and standby route-processor line cards.
The ECU is located behind the craft panel.
external connection unit (ECU)
The craft panel can install, configure, monitor, and
troubleshoot the Cisco NCS 4009 chassis applications
at the node and at the network level. The craft panel
is located on top of the ECU.
craft panel
One fan tray is inserted into the front of the chassis
behind the craft panel. The fan tray cools the card
rack. The fan tray contains six axial fans. The fans
pull cooling air through the chassis from front to rear.
fan tray
One air filter is located above the slots of the fabric
cards.
