Inserting a Line Card
Inserting a Line Card
When a line card is inserted into a chassis being managed by Cisco 12000/10720 Router Manager, then
the EMS detects that a line card has been inserted through the chassis heartbeat polling (which occurs
every minute). Once the EMS detects that the line card is inserted, an informative alarm is raised against
the respective chassis object in Cisco 12000/10720 Router Manager with a description
The chassis
configuration has changed . After this the chassis rediscovers itself and all its child objects. After the
chassis has been rediscovered, the line card and interface objects for the newly inserted line card with
its associated graphic will be deployed and commissioned against the appropriate slots. It is placed in
the appropriate state in the device in both the componentManaged view and the Physical view. The OSI
icons for line cards and interfaces discovered after insertion and in normal state are displayed below.

Mismatched State
The mismatched state occurs when a mismatch is found between the hardware and what is deployed in
Cisco 12000/10720 Router Manager. The mismatched state appears if you insert an incorrect module that
does not correspond with the module type that has been pre-deployed in Cisco 12000/10720 Router
Manager, or, if the pre-deployment for the new module is incorrect. For example: you are expecting an
ATM OC-3 line card, so you pre-deploy and pre-configure Cisco 12000/10720 Router Manager to
prepare for that type of line card. Now, when the line card becomes available and is placed into the
chassis, it is not an ATM OC-3 line card, but a POS OC-3 line card. What happens? Once the Cisco
12000/10720 Router Manager detects the new line card, it finds a mismatch. The line card gets placed
into the mismatch state and a major alarm is raised against the line card.
To rectify a mismatch problem, first you must assess the source of the problem. If the operator was at
fault and pre-deployed an incorrect module, the operator should decommission and delete the
pre-deployed module and re-deploy the correct module. If the engineer is at fault and inserted the wrong
type of module into the chassis, then the module should be removed. When you remove a module, Cisco
12000/10720 Router Manager moves that module into a lost comms state. When the correct module is
re-inserted, Cisco 12000/10720 Router Manager finds the new module and downloads the correct
pre-deployment and pre-configuration information, then places the module into a normal state.
