To display information about the Cisco CMTS physical environment, including internal temperature,
midplane voltages, fan performance, and power supply voltages, use the
debug cable env
command in
privileged EXEC mode. To disable debugging output, use the
no
form of this command.

Usage Guidelines
This command is used to debug the sensor circuitry used to measure internal temperature, midplane
voltages, fan performance, and power supply voltages on the Cisco CMTS console.
Examples
The following example shows sample output displayed by the
debug cable envm
command
Router#
debug cable envm
ENVM: ps id=0xFF0, v=0x2050, r=0xC0AB, pstype=1
ENVM: ps id=0x2FD0, v=0x2050, r=0x24201, pstype=27
NVM: Sensor 0: a2dref=131, a2dact=31, vref=12219, vact=1552 Alpha=8990, temp=27

Sample Output for the debug cable envm Command
Field
Description
ps id
Power supply raw voltage reading.
pstype
Power supply type determined from ps ID, v, and r. If the
Cisco CMTS contains dual power supplies, the ID information for
two types is usually printed.
Sensor
Sensor number.
a2dref
Analog-to-digital converter reference reading.
a2dact
Analog-to-digital converter actual (measured reading).
vref
Reference voltage.
vact
Actual voltage.
Alpha
Raw temperature reading.
temp
Temperature corresponding to Alpha.
