Chassis

Cisco 12000 Series Internet Routers are available in the following configurations:

Cisco 12000 Series Internet Routers Switching Capacity Slots Configuration
10 Gbps Internet Routers
Cisco 12416 320 Gbps 16 Full rack
Cisco 12410 200 Gbps 10 Half rack
Cisco 12406 120 Gbps 6 Quarter rack
Cisco 12404 80 Gbps 4 Eighth rack
2.5 Gbps Internet Routers
Cisco 12016 80 Gbps (upgradable*) 16 Full rack
Cisco 12012 60 Gbps 12 Full rack
Cisco 12008 40 Gbps 8 Third rack

* The Cisco 12016 may be upgraded to a Cisco 12416 using a switch fabric upgrade kit.

Chassis Slot Overview

Slots 0-15 are for line cards (LCs) (not all chassis support 16 LCs). The Gigabit Route Processor (GRP) can be put in any of these slots. On the Cisco 12012, we recommend using slot 0 and 11 for the GRP, because these slots don't cool as well and the GRP dissipates less heat than the other LCs. The 12016 and 12416 are the same chassis. The only difference is the clock and scheduler card (CSC) and switch fabric cards (SFCs). The 12016 uses the GSR16/80-CSC and GSR16/80-SFC, while the 12416 uses the GSR16/320-CSC and GSR16/320-SFC. If you have a 12016 and want to "upgrade" it to a 12416, all you have to do is replace the GSR16/80-CSC and GSR16/80-SFC with the new GSR16/320-CSC and GSR16/320-SFC.

The alarm cards are integrated into the CSC cards for the 12008. All other chassis have separate alarm cards. The table below provides the slot numbers and corresponding line cards for all chassis:

Slot Number Line Card
0-15 LC/GRP
16 CSC0
17 CSC1
18 SFC0
19 SFC1
20 SFC2

The table below provides chassis-specific information:

Router Slot Number Line Card
12008 24 Power supply A1 (upper)
26 Power supply B1 (lower)
12012 - Notes:
  • The Alarm card does not show up separately.
  • Use slots 0 and 11 for the GRP since these slots don't cool as well and the GRP emits less heat than the other LCs.
24 Power supply 1 (A1)
25 Power supply 2 (A2)
26 Power supply 3 (B1)
27 Power supply 4 (B2)
28 Top fan and blower module
29 Bottom fan and blower module
12016 and 12416 24 Upper alarm card
25 Lower alarm card
26 Unused
27 Busboard
28 Top fan and blower module
29 Bottom fan and blower module
12406 24 Power supply 1 + alarm module
25 Power supply 2 + alarm module
28 Blower module (top fan)
29 Blower module (bottom fan)
12410

Note: On this chassis, there are five specific SFCs

21 SFC3
22 SFC4
24 Power supply 1 + alarm module
25 Power supply 2 + alarm module
28 Blower module (top fan)
29 Blower module (bottom fan)
