Environmental Monitoring and Reporting Functions
The reporting functions periodically log the values of measured parameters so that you can retrieve
them for analysis later, and the reporting functions display warnings on the console if any of the
monitored parameters exceed defined thresholds.
them for analysis later, and the reporting functions display warnings on the console if any of the
monitored parameters exceed defined thresholds.
In addition to monitoring internal temperature and voltage levels, the system also monitors the
blower. If the blower fails, the system displays a warning message on the console. If the blower is
still not operating properly after 2 minutes, the system shuts down to protect the internal components
against damage from excessive heat.

Environmental Monitoring
Three sensors on the Route Switch Processor (RSP2 or RSP4) monitor the temperature of the
cooling air that flows through the processor slots: inlet, hotpoint, and exhaust. The sensors are
located at the bottom, center, and top of the RSP, when facing the interface processor end of the
chassis and viewing the RSP as it is installed.

The power supply uses the Normal, Critical, and Warning levels to monitor DC voltages. Table 2
lists temperature thresholds for the three processor-monitored levels. Table 3 lists the DC power
thresholds for the Normal and Critical (power supply-monitored) levels. The following is an
explanation of the monitor levels and actions that take place when certain conditions are present:
lists temperature thresholds for the three processor-monitored levels. Table 3 lists the DC power
thresholds for the Normal and Critical (power supply-monitored) levels. The following is an
explanation of the monitor levels and actions that take place when certain conditions are present:
•
Normal—All monitored parameters are within normal tolerances. The system blower operates at
55 percent of its maximum speed if the internal air temperature does not exceed this level.
55 percent of its maximum speed if the internal air temperature does not exceed this level.
•
Warning (low and high)—The system is approaching an out-of-tolerance condition. The system
continues to operate, but operator monitoring or action is recommended to bring the system back
to a normal state. If the internal air temperature is in the normal range, the blower speed increases
linearly from 55 percent of maximum speed until it reaches 100 percent speed at 33 C (91 F).

linearly from 55 percent of maximum speed until it reaches 100 percent speed at 33 C (91 F).
•
Critical (low and high)—An out-of-tolerance temperature or voltage condition exists. The
system may not continue operation. If a voltage measurement reaches this level, the power supply
can shut down the system. If the blower fails, the system displays a warning message and shuts
down in 2 minutes. Immediate operator action is required.

down in 2 minutes. Immediate operator action is required.
•
Processor shutdown—The chassis interface has detected a temperature or blower-failure
condition that could result in physical damage to system components and has disabled DC power
to all interface processors (in slots 0 through 5 and 8 through 12). DC power to the RSP, chassis
interface, and blower stays on, but no RSP-related processing takes place. Immediate operator
action is required. DC power remains off until the inside temperature of the chassis reaches 40 C
(104 F), at which point the system restarts up to 15 times (if required). If the source of the
shutdown has not been corrected, the system executes a hard shutdown. Before any shutdown,
the system logs the status of monitored parameters in NVRAM so that you can retrieve it later to
help determine the cause of the problem.

•
Power supply shutdown—An out-of-tolerance voltage, current, or temperature condition was
detected within the power supply and it was shut down (or a shutdown is imminent). All DC
power remains disabled until the operator toggles the power switch and corrects the problem that
caused the shutdown (if any). This condition typically occurs for one of the following reasons:
