Inserting a Line Card
Insert ing a Line Ca rd
When a line c ard is inserted into a ch assi s being managed by Cisco 12000/10720 Route r Manager, then
the EMS detects that a line card has been inserted through the chassis heartbeat polling (which occurs
e ver y minute) . Once the EMS det ects that the line ca rd is insert ed, an infor mati ve ala rm is raised ag ainst
the respect ive chassis object i n Cisco 12000/1 0720 Route r Manager wit h a descripti on The c hassis
configuration has changed. After this the chassis rediscover s itself an d all its ch ild obje cts. Afte r 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 de vice 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 co rre spo nd w ith the m odu le type tha t h as been p re-de ployed in Cisc o 1 200 0/107 20 Rout er
Manage r, or, if the pre-d ep loym ent for t he new modul e is in cor re ct. For exampl e: you are expe c tin g an
ATM O C-3 l ine ca rd, so y ou pre-d ep loy an d pre-c on figure C isco 12000/ 1 0720 R out er Ma nage r 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
12000/10 720 Rout er Manage r detec ts the new line card , it finds a mismatch . The lin e card get s place d
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 -depl oyed an inc orr ect modu le, the o pera tor shou ld d ecom missi on and de lete 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
12000/10 720 Route r Manage r moves that module int o a lost comms st ate. When t he correc t modul e is
re-inserte d, Cisco 120 00/10 720 Ro ute r Ma nage r finds the new module and download s the cor rect
pre-de ploym ent and pr e- configur ati on i nfo rm atio n, th en pla ces the mo dule in to a n orm al st ate .
