Servicing Hardware
After you replace a system card or change its physical configuration, you must
enter commands from the command-line interface (CLI) to restore the card
to normal operations.
The design of the SmartEdge 600 router permits you to install and replace all
cards without powering off the system.
Caution!
Risk of equipment malfunction. If you install or replace a card in a running
system and the system is not fully operational, you can cause the system to
malfunction.
Make sure the system is fully operational before proceeding with installation
or replacement procedures:
•
In a system with dual controller cards, ensure that the standby controller
is fully synchronized with the active controller card. Use the
show
redundancy
command (in any mode) to display the status of the standby
controller.
•
In a system with a single controller card, ensure that you have the CLI
prompt on the console.
•
If the system is not currently in an operational state, you need to power off
the system. To power off the system, remove all fuses in the fuse panel.
•
The SmartEdge 600 router has an EEPROM that supplies the medium
access control (MAC) address for the chassis. If it should ever be necessary
to replace the EEPROM, consult your local technical representative.
•
If the controller cards are not the same type with same main memory
configuration, the system might need to shut down one or more line
cards to free up enough available power for the standby controller card.
The operating system always reserves enough power during system
configuration so that if the system has only a single controller card installed,
a standby controller card of the same type can be installed at a later time.
•
If the controller cards are mismatched, the system issues an alarm for
mismatched controllers, allocates power for the second controller card, and
recalculates available power. If the available power is not sufficient to power
all the installed line cards, the operating system begins putting installed line
cards into low-power mode, starting with the highest-numbered slot, until
enough power is available to initialize the standby controller card.
