Chapter 2 Preparing for Installation
Environmental Monitoring and Reporting Overview for the Cisco 7500 Series
The current temperature measurements at the three RSP sensors are displayed as inlet, hotpoint, and
exhaust. The shutdown temperature source is the hotpoint sensor, which is located toward the center of
the RSP. System voltage measurements are also displayed, followed by the system current measurements
and power supply wattage calculation.
Note
The current monitor circuits of the 7513 power supply are only accurate at high power levels. They are
there to prevent over-configuration and serve no purpose at low power levels. If the system is not
operating above 70% power, the measurement results are not accurate. Above 70%, the measurements
have the degree of accuracy needed to prevent the insertion of too many line cards into the system.

15 of 15 soft shutdowns remaining before hard shutdown
Note
When the system temperature increases above the board shutdown level, a soft shutdown occurs (that is,
the processor modules are shut down, and the power supplies, fans, and CI continue to operate). When
the system cools to the restart level, the system restarts. The system counts the number of times this
occurs and keeps the up/down cycle from continuing endlessly. When the counter reaches zero, the
system performs a hard shutdown, which requires a power cycle to recover. The soft shutdown counter
is reset to its maximum value after the system has been up for 6 hours.
