Chassis Management Displays
Field
Means
Power Supply:
The number of the power supply shown in this display.
Status:
The current state of the power supply. Possible states are these:
Required
This power supply must be available to support the modules
in the chassis. The other power supplies cannot compensate
for its power if it becomes disabled.
Redundant This power supply need not be available to support the
modules in the chassis. Another power supply can
compensate for its power if it becomes disabled. If two or
more redundant power supplies become disabled, however,
other power supplies do not necessarily compensate for the
loss of power. In a chassis with two redundant power
supplies, for example, at least one must be available.
Disabled
This power supply is not supplying power to the chassis.
The serial number of this power supply.
Serial #
The version of the single chip microcontroller (SCM) for this power
supply.
SCM Version
Warnings:
The status of various warnings on the PS/130 power supply. This field
includes two categories for each type of warning: Current and Historical.
Current warnings are those that represent the status in the the latest
message that the power supply broadcast to the LMB. Historical warnings
are those that represent the status in previous broadcasts.
The display includes these warnings:
Warning
Means
Out of Range
One of the voltage levels was too high or too
low.
Thermal Warning
The power supply is or was approaching an
unacceptably high temperature.
Thermal Shutdown
The power supply exceeded the maximum
allowable temperature, and this caused the
power supply to shutdown.
Hardware Inhibit
The power supply is or was inhibited, because
a user pushed the On/Off switch into the Off
position.
