Redundant Power; Environmental Monitoring And Reporting Functions - Cisco 7000 Hardware Installation And Maintenance

To display the current microcode version for each interface processor, enter the show controller
cxbus command. The following example shows that the SP is running Microcode Version 1.4, and
the FSIP is running Microcode Version 1.0:
7010# show cont cxbus
Switch Processor 5, hardware version 1.1, microcode version 1.4
FSIP 0, hardware version 4, microcode version 1.0
Although most microcode upgrades are distributed on floppy disk, some exceptions may require
ROM replacement. If so, refer to the section "Microcode Component Replacement" in the chapter
"Maintenance" for EPROM replacement procedures. (Instructions are also provided with the
upgrade kit.) For complete command descriptions and instructions, refer to the related software
documentation.

Redundant Power

One 700W, AC-input or DC-input power supply is standard in the router. A second, identical power
supply can be installed to provide redundant power. Dual power supplies are load sharing; when two
power supplies are installed and both are operational (both are turned on), each concurrently
provides about half of the required power to the system. If one of the power supplies fails, the second
power supply ramps up to full power to maintain uninterrupted system operation. Dual power
supplies should be connected to separate input lines so that, in case of a line failure, the second
source will most likely still be available. Load sharing and redundancy are automatically enabled
when the second power supply is installed; no software configuration is required.
Caution
chassis. Your Cisco 7000 must have either DC-input or AC-input power supplies.

Environmental Monitoring and Reporting Functions

The environmental monitoring and reporting functions enable you to maintain normal system
operation by identifying and resolving adverse conditions prior to loss of operation. Environmental
monitoring functions constantly monitor the internal chassis air temperature and DC line voltages.
Each power supply monitors its own voltage and temperature and shuts itself down if it detects a
critical condition within the power supply. If conditions reach shutdown thresholds, the system shuts
down to avoid equipment damage from excessive heat or current. The reporting functions enable you
to retrieve and display the present values of measured parameters, and the reporting functions
display warnings on the console if any of the monitored parameters exceed defined thresholds.
Timesaver
power supplies are in your chassis: DC-input or AC-input. As a general precaution, use the show
environment all command and note the type of power supply indicated in each of your chassis
(indicated as either "700W DC" or "700W AC"). Record and save this information in a secure place.
Note
show environment all command will indicate the AC-input power supply as "850W." A DC-input
power supply will still be indicated as "700W."
