4.2.3.3 Over Temperature Protection (OTP)
There is not a requirement of thermal sensor located on the cage and have OTP function itself.
If there is no OTP function build in the cage, the cage should be protected by the OTP function
in the module when over heated with no unrecoverable damage.

Control and Indicator Functions (Hard-wired)

The following sections define the input and output signals from the power distribution board.
Signals that can be defined as low true use the following convention:
signal# = low true
4.2.4.1 PSON# Input and Output Signals
#
The PSON signal is required to remotely turn on/off the power supply. PSON
signal that turns on the +3.3V, +5V, +12V, and -12V power rails. When this signal is not pulled
low by the system, or left open, the outputs (except for the +5VSB) turn off. This signal is pulled
to a standby voltage by a pull-up resistor internal to the power supply.
Signal Type
PSON = Low

PSON = High or Open
#
Logic level low (power supply ON)
Logic level high (power supply OFF)
