Removing a Line Card
Example 19-2 Scenario 2
Scenario 2—If a line card have been pre-deployed incorrectly in the Cisco 12000/10720 Router Manager
and commissioned.
This can occur if an incorrect line card type is pre-deployed and commissioned. For example, if an 8 port
fast Ethernet line card is pre-deployed against slot-0, but the slot-0 of the device actually has a 3 port
gigabit Ethernet line card inserted, then commissioning the pre-deployed line card will result in a
mismatched state.
To rectify the line card mismatch problem caused due to the above scenario, decommission and delete
the mismatched line card object and redeploy the correct type of line card object.
Removing a Line Card
When you remove an existing line card from a chassis, Cisco 12000/10720 Router Manager detects that the
line card has been removed by heartbeat polling (which occurs every minute). Once Cisco 12000/10720
Router Manager detects that the line card is removed, an informative alarm is raised against the chassis
object in Cisco 12000/10720 Router Manager with a description
The chassis configuration has
changed
. The chassis rediscovers itself and its child objects. After this process, the removed line card is
placed in the lost comms state, which causes a major alarm to be raised against that line card. This situation
is rectified when the line card is re-inserted in the chassis. When the line card is re-inserted into the chassis,
the chassis rediscovers itself and its child objects due to change in the hardware configuration. The
re-inserted line card is placed in the appropriate state and the previously raised major alarm is cleared.
After the chassis has been rediscovered the removed line card object will be moved to lostcomms state
with a major alarm raised against the line card object with the description
Connection to the device
lost
. Similarly all the interface objects of the removed line card object will also be moved to lostcomms
state.
The removed line card object and all its interface objects are hashed and display an OSI Icon as displayed
below, under the Component Managed and Physical (object’s GIFs) views.
