pft(8) (RM400 only) pft(8)
NAME
ptf - command for checking the voltage and temperature sensors
SYNTAX
/sbin/ptf [-p] [-t] [-f] [-b] [-P] [-T] [-F] [-B]
DESCRIPTION
The ptf command allows the user to query the current status of the
BBU, the voltage, temperature, and fan sensors for using the
/dev/at/ptf device [see ptf(7)].
A maximum of 8 devices of the same type are supported in a system
cabinet (e. g. up to 8 power supply units). If there is no device of
the requested type available in the system cabinet, "-" is output. The
output is left justified. The devices are output in the following
sequence: no0, no1, no2, no3, no4, no5, no6, no7.
OPTIONS
-p Displays the status of the power supply unit - A letter is output
for every device identified.
Either a "P" or "p" is output for every available power supply
unit that is identified. A "P" is output if a power supply unit
is identified as being available, but neither an environment
error (power failure) nor a device error (defective power supply
unit) was detected. A "p" means that a device is available but an
error has occurred.
Example:
# ptf -p
Pp
Explanation:
Two power supply units were identified, one of which (no0) is Ok.
The other power supply unit (no1) has reported an error. (A "PP"
cannot arise at present because a redundant power supply unit
cannot be identified in the normal state)
-P Displays the status of the power supply unit - A hexadecimal
value is output for every device identified.
Each device status is composed of four bits (therefore in total a
Nibble).
0x1 Device is identified (exists)
0x2 Device error (e. g. defective power supply unit)
0x4 Special bit (reserved, but not used at present)

pft(8) (RM400 only) pft(8)
0x8 Environment error (e. g. power failure)
Example:
# ptf -P
19000000
Explanation:
Two power supply units were identified, one of which (no0) is Ok.
The other power supply unit (no1) has reported an environment
error (power failure).
-t Displays the status of the temperature sensor - A letter is out-
put for every device identified.
Similar to -p. A "T" or "t" (sensor damaged or tempfail) is out-
put for every available temperature sensor that is identified.
-T Displays the status of the temperature sensor - A hexadecimal
value is output for every device identified.
Similar to -P.
-f Displays the status of the fan sensor - A letter is output for
every device identified.
Similar to -p. An "F" or "f" (fanfail) is output for every avail-
able fan that is identified.
-F Displays the status of the fan sensor - A hexadecimal value is
output for every device identified.
Similar to -P.
-b Displays the status of the BBU - A letter is output for every
device identified.
Similar to -p. Either a "B" or "b" (BBU damaged oder BBU active)
is output for every available BBU that is identified.
Example:
# ptf -b
-
-B Displays the status of the BBU - A hexadecimal value is output
for every device identified.
Similar to -P.
