Syntax

preserve-fpc-poweron-sequence;

Hierarchy Level

[edit chassis]

Description

Preserve the sequence in which the line cards—specifically, MPCs on MX series routers—on a router or switch are powered on when the device is restarted. During a system reboot, the line cards are brought online in the sequence specified in the system log file /var/log/ fpc_poweron_seq.log. When a line card goes offline, its entry is removed from the log file. You can use the show chassis power sequence command to view the configured power-on sequence.

Note:
  • If both preserve-fpc-poweron-sequence and fru-poweron-sequence statements are configured, then the power-on sequence specified in the fru-poweron-sequence statement takes precedence.

  • If preserve-fpc-poweron-sequence is configured and fru-poweron-sequence not configured, then the line cards are powered on in the sequence preserved in the system log file /var/log/ fpc_poweron_seq.log.

  • If neither of these statements is configured, then the line cards are powered on in the ascending order of their slot numbers. Line cards whose slot numbers are not specified in the log file are powered on in the ascending order of their slot numbers.
