     • For model 520: Remove the model 520 RAID enablement card
     • For model 570: Exchanging the RAID enablement card in the model 561 and 570
2. Remove the card using the concurrent card removal and replacement procedure for the model or expansion unit that you are working on (see Removing and replacing parts).

   • For type 2748, 2763, and 2778 cards, continue with the next step.
   • For type 2757, 2780, 2782, 5703, 5709, 571B, and 573D cards, go to step step 7.
   • For type 571E cards, go to step 10.
4. Locate the cache directory card B. It is a small rectangular card mounted on the I/O card (see Figure 1).

   Spread the tabs on each side of the cache directory card, and raise the back of the cache directory card B up and away from the I/O card. The cache directory card will pivot up about 20 degrees.

5. Pull the cache directory card out.
6. Install the replacement cache directory card by wiggling it into place at a 20-degree angle before pushing it down and locking the tabs. Be sure that the holes on each side of the cache directory card are filled by the pegs on the cache card to ensure proper seating. This ends the procedure.
7. Locate the cache directory card B. It is a small rectangular card mounted on the I/O card (see Figure 2, Figure 3, Figure 4, Figure 5 or Figure 6).
8. Unseat the connector on the cache directory card by wiggling the two corners that are farthest from the mounting peg by using a rocking motion. Then, pivot the cache directory card back over the mounting peg to disengage the cache directory card from the mounting peg.
   Note: For the type 2757 card, do not remove the larger card with the two mounting pegs.
9. Install the replacement card by seating it on the connector and mounting peg. This ends the procedure.
