SmartEdge 600 Router Hardware Guide
Stop!
Risk of data loss. Verify that the card being removed is not the active controller
(that is, the STDBY LED is lit). Controller cards are hot swappable, but if the
system configuration includes redundant controller cards, you can disrupt traffic
if you remove the active controller card.
To replace a controller card:
1. For dual controller cards, ensure that the system is fully operational: the
standby controller must be fully synchronized with the active controller
card. Use the
show redundancy command to display the status of the
standby controller.
2. For duel controller cards, upgrade the active controller to run the latest
release of the system software.
3. For a controller card with a CF card installed, dismount the device by
entering the following command in exec mode:
unmount /md
Removing the controller card with its CF card without first entering the
unmount /md command can permanently damage the device and cause
the kernel to crash.
Stop!
Risk of data loss. Do not enter the unmount /md command while the
CF ACTIVE LED is blinking. You can lose data that is being transferred
to the CF card if you enter the unmount /md command before the data
transfer operation is complete. When the operation is complete, the LED
is turned off.
4. Put on an antistatic wrist strap, and attach it to an appropriate grounded
surface. Do not attach the wrist strap to a painted surface; an ESD
convenience jack is located on the front of the fan tray.
5. Label and disconnect any cables from the front of the controller card being
removed.
6. Remove the current card.
7. Install the card.
