In the Cisco 7507 and Cisco 7507-MX, 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 RSP temperature sensors and the power supply voltages. The show
environment all command also displays a report showing which slots in the Cisco 7507 or Cisco
7507-MX are occupied (indicated by an X) and which are empty.
Active fault conditions are indicated when the blower or power supply has failed or is not present. The
system expects to see one blower in the Cisco 7507 or Cisco 7507-MX, the main system blower.
The system blower is designated #1. The active fault condition in the following example shows that there
is no power supply installed in power bay A because the display indicates that power supply #1 (in the
lower bay) is removed.
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 entry
refers to the number of times the system will reset itself before it executes a complete system (or hard)
shutdown.
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. Following is sample output of the show env all command:
Router# show env all
Arbiter type 1, backplane type 7507 (id 4)
Power supply #1 is removed (id 3), power supply #2 is 700W (id 2)
Active fault conditions: none
Active trip points: Restart_Inhibit
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 15, the system
performs a hard shutdown, which requires a power cycle to recover. The soft shutdown counter is reset
to its minimum value after the system has been up for 6 hours.
