Upgrading the 1200-Watt, AC-Input Power Supplies in the Cisco 7513
OL-6324-01
Product Overview
The show environment table command displays the temperature and voltage thresholds for each of the
three RSP2 temperature sensors, for each monitored status level: low critical, low warning, high
warning, and high critical, which are the same as those listed in Tables 2 and 3. The slots in which the
RSP2 can be installed are indicated in parentheses (6 and 7). Also listed are the shutdown thresholds for
the processor boards and power supplies. Following is sample output of the show env table command:

Note Temperature ranges and values are subject to change.
The show environment all command displays an extended report that includes the arbiter type,
backplane type, power supply type (AC or DC), wattage and status, the number and type of intermittent
power failures (if any) since the system was last powered on, and the currently measured values at the
RSP2 temperature sensors and the DC-input lines. The show environment all command also displays a
report showing which slots in the Cisco 7513 are occupied (indicated by an X) and which are empty.
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.
Active fault conditions are indicated when the blower or power supply has failed or is not present (as
“Blower #3” indicates in the following example). The system expects to see three blowers or fans in the
Cisco 7513: the main system blower, and one fan in each power supply. The system blower is designated
#1, the power supply fan in power bay A is #2, and the power supply fan in power bay B is #3. The active
fault condition in the following example shows that there is no power supply installed in power bay B
because the display indicates that power supply #2 (in power bay B) is removed. System blower speed
is displayed as a percentage of maximum.
There are four active trip points: restart OK, temperature warning, board shutdown, and power supply
shutdown. (There are no active trip points shown in the following example.) The soft shutdowns refer to
the number of times the system will reset itself before it executes a complete chassis (or hard) shutdown.
The current temperature measurements at the three RSP2 sensors are displayed as inlet, hotpoint, and
exhaust. The shutdown temperature source is the hotpoint sensor, which is located toward the center of
the RSP2. System voltage measurements are also displayed, followed by the system current
measurements and power supply wattage calculation. Following is sample output of the show env all
command:
