Maintaining the PTX5000 FPCs
Purpose For optimum packet transport switch performance, verify the condition of the FPCs.
Action On a regular basis:
• Check the LEDs on the FPC. During normal operation:
• The green OK LED located the bottom of the FPC lights steadily when the FPC is
online and functioning normally. The green OK LED blinks during startup.
• Issue the CLI show chassis fpc command to check the status of installed FPCs. The
value Online in the column labeled State indicates that the FPC is functioning normally.
• Issue the CLI show chassis environment fpc command to check the temperature and
power of installed FPCs. The temperature values should be below the preconfigured
thresholds. The power values provide Information about the voltage supplied to the
FPC. The left column displays the required power, in volts. The right column displays
the measured power, in millivolts.
• Issue the show chassis fabric topology command. During normal operations, the output
for the command shows that the state of the online SIBs and FPCs links are in the OK
state.

Maintaining the PTX5000 Host Subsystem
Purpose For optimum packet transport switch performance, verify the condition of the host
subsystem. Each host subsystem comprises a Routing Engine and an adjacent control
board functioning together.
Action On a regular basis:
• Check the host subsystem LEDs OK and Fail on the craft interface for (HOST0 and
HOST1. For more information about the LEDs on the craft interface, see “PTX5000
Craft Interface LEDs” on page 28.
During normal operations:
• The green host subsystem OK LED on the craft interface is lit.
• The red host subsystem FAIL LED on the craft interface is not lit.
