Confirm that transporting CompactFlash is the appropriate action to take as discussed in the ME4 Series Storage System Deployment
Guide. Refer to CompactFlash memory card location
Before you begin any procedure, see
1. Locate the CompactFlash memory card at the midplane-facing end of the failed controller module.
2. Grip the CompactFlash memory card and carefully pull it from the slot in the failed controller module.
3. Label the CompactFlash memory card as Data, and set it aside for safekeeping.
4. Locate the replacement controller module, and carefully remove its installed CompactFlash memory card.
a) Take care not to confuse this diskette with the one labeled Data.
b) Insert this CompactFlash memory card into the failed controller module.
5. Align the CompactFlash memory card labeled Data for insertion into the replacement controller module—then insert it into the slot—
and push it forward until seated in place.
Removing a controller module
Before you begin any procedure, see
NOTE: Considerations for removing controller modules:
• In a dual-controller module environment, you may hot-swap a single controller module in an operational enclosure,
provided you first shut down the controller module using the ME Storage Manager or the CLI.
• In a dual-controller module environment—if replacing both controller modules—you must adhere to the instructions
provided in ESD precautions.
• Do not remove a faulty controller module unless its replacement is on-hand. All controller modules must be in place
when the system is in operation.
1. Verify that you have successfully shut down the controller module using the ME Storage Manager or the CLI.
2. Locate the enclosure with a UID LED that is illuminated.
3. Within the enclosure, locate the controller module with an OK to Remove LED that is blue.
4. Disconnect any cables connected to the controller module.
Label each cable to facilitate re-connection to the replacement controller module.
5. Grasp the module latch between the thumb and forefinger, and squeeze the flange and handle together to release the latch handle,
and swing the latch handle out to release the controller module from its seated position.
