This section contains additional troubleshooting information to help you isolate the cause of a power
problem.
Hardware and Software Identification
The power modules have software IDs that differ from the hardware ID labels on the chassis. Table 4-2
is a table for converting power module hardware IDs to software IDs.
Obtaining Temperature and Environmental Information
If both the RP and the fan tray are operating, all internal correct DC voltages are present.
Enter the show environment command at the router admin prompt to display temperature and voltage
information for each installed card, fan tray, and power module as shown in this example:
RP/0/RSP0/CPU0:router(admin)#show environment
