Environment Monitoring
To see what types of DFCs are in the chassis, use the show chassis slot command in privileged EXEC
mode:
Router# show chassis slot
Slot 1:
DFC type is AS5400 T1 8 PRI DFC
OIR events:
Number of insertions = 0, Number of removals = 0
DFC State is DFC_S_OPERATIONAL
Slot 2:
Carrier Slot is Empty
Slot 3:
Carrier Slot is Empty
Slot 4:
DFC type is AS5400 NP108 DFC
OIR events:
Number of insertions = 0, Number of removals = 0
DFC State is DFC_S_OPERATIONAL
Slot 5:
DFC type is AS5400 Empty DFC
DFC is not powered
OIR events:
Number of insertions = 0, Number of removals = 0
Slot 6:
Carrier Slot is Empty
Slot 7:

Environment Monitoring
The Cisco AS5400XM contains temperature sensors to detect abnormal temperature conditions during
system operation. The three levels of sensor detection are as follows:
1. When the operating temperature of the system exceeds 113
° F (45° C), the system reaches a warning
state. A warning message appears on the console. When the operating temperature of the system
drops below 113
° F (45° C), another message is displayed on the console indicating a recovery. At
this level of sensor detection, there is no disruption in system operation.
2. When the operating temperature of the system continues to rise above 113
° F (45° C) and reaches a
temperature of 140
° F (60° C), the system reaches a critical state.
Cisco IOS software busys out the DFCs in the chassis and shuts down the first DFC. If the operating
temperature continues to be critical after 10 minutes, Cisco IOS software shuts down another DFC.
This process is repeated at 10-minute intervals until the final DFC is shut down. The console
displays the slot number of the DFC and the type of DFC that was shut down.
Note DFC slot numbering starts from the system board and works up from left to right. Slot 0 is
reserved for the system board. The DFC slots are numbered sequentially from 1 to 7.
