Description
route processor cards (RPs) 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.
fabric cards (FCs)
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.
line cards (LCs)
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.
external connection unit
(ECU)
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.
