If the now option is specified, no boot confirmation messages appear.
Parameters active — keyword to reboot the active CSM
Default active
standby — keyword to reboot the standby CSM
Default active
upgrade — enables card firmware to be upgraded during chassis reboot. The 7705 SAR
and the boot.ldr support functionality to perform automatic firmware upgrades on
CSMs. The automatic upgrade must be enabled in the 7705 SAR Command Line
Interface (CLI) when rebooting the system.
When the upgrade keyword is specified, a chassis flag is set for the Boot Loader
(boot.ldr) and on the subsequent boot of the 7705 SAR on the chassis, any firmware
images on CSMs requiring upgrading will be upgraded automatically.
If a 7705 SAR is rebooted with the “admin reboot” command (without the “upgrade”
keyword), the firmware images are left intact.
Any CSMs that are installed in the chassis will be upgraded automatically. For
example, if a card is inserted with down revision firmware as a result of a card hot
swap with the latest OS version running, the firmware on the card will be
automatically upgraded before the card is brought online.
If the card firmware is upgraded automatically, a CHASSIS “cardUpgraded” (event
2032) log event is generated. The corresponding SNMP trap for this log event is
“tmnxEqCardFirmwareUpgraded”.
During any firmware upgrade, automatic or manual, it is imperative that during the
upgrade procedure:
• power must NOT be switched off or interrupted
• the system must NOT be reset
• no cards are inserted or removed
Any of the above conditions may render cards inoperable requiring a return of the
card for resolution.
The time required to upgrade the firmware on the cards in the chassis depends on
the number of cards to be upgraded. On system reboot, the firmware upgrades can
take from approximately 3 minutes (for a minimally loaded 7705 SAR) to 8 minutes
(for a fully loaded 7705 SAR chassis), after which the configuration file will be loaded.
The progress of the firmware upgrades can be monitored at the console. Inserting a
single card requiring a firmware upgrade in a running system generally takes less
than 2 minutes before the card becomes operationally up.
