Owners Manual

NOTE: The previous figures show a 4-port SAS controller module. However, all of the controller modules use the same
latching mechanism.
4. Swing the latch handle open, then grip the latch handle and ease the controller module forward from the slot.
5. Place both hands on the controller module body, and pull it straight out of the enclosure such that the controller module
remains level during removal.
Moving the CompactFlash memory card for a single-controller module enclosure
This procedure applies to single-controller module enclosure configurations only. The CompactFlash memory card must be
moved from the failed controller module to the replacement controller module to prevent data loss.
Confirm that transporting CompactFlash is the appropriate action to take as discussed in the Troubleshooting and problem
solving chapter of the ME4 Series Storage System Deployment Guide.
CAUTION: Do not move the CompactFlash cards in a dual-controller module environment. The cache is
duplicated between the CompactFlash memory cards in dual-controller module environments.
Before you begin any procedure, see ESD precautions on page 43.
1. Remove the failed controller module from the controller enclosure.
2. Locate the CompactFlash memory card at the midplane-facing end of the failed controller module.

3. Grip the CompactFlash memory card and carefully pull it from the slot in the failed controller module.
4. Label the CompactFlash memory card as Data, and set it aside for safekeeping.
5. Locate the replacement controller module, and remove its installed CompactFlash memory card.
6. Insert the CompactFlash memory card from the replacement controller module into the failed controller module.
Take care not to confuse this memory card with the memory card labeled Data.
7. Insert the CompactFlash memory card labeled Data into the replacement controller module. Push the memory card forward
until it is seated in place.
