Separating the 572F/575C card set and moving the cache directory card

When the maintenance procedures direct you to separate the 572F/575C card set and move the cache directory card on a 572F controller for recovery purposes, carefully follow this procedure.

Important: To avoid loss of cache data, do not remove the cache battery during this procedure.

Notes:

This procedure should only be performed if directed from an isolation procedure or a maintenance analysis procedure (MAP).
If you are removing the adapter from a double-wide cassette, go to the procedures in your system unit's service information for removing a double-wide adapter from a double-wide cassette.

Attention: All cards are sensitive to electrostatic discharge. See Handling static-sensitive devices before beginning this procedure.

To separate the 572F/575C card set and move the cache directory card, complete the following steps.

Label both sides of the card before separating them.
Place the 572F/575C card set adapter on an ESD protective surface and orient it as shown in Figure 1.

To prevent possible card damage, loosen all five retaining screws C before removing any of them. After all five retaining screws have been loosened, remove the screws C from the 572F storage adapter.
Important: Failure to loosen all five retaining screws prior to removing any of the screws can result in damage to the card.

Grasp the 572F and 575C adapters close to the interconnect connector A , as shown in the following figure, and carefully pull the connector apart; then, set the adapters on the ESD protective surface.

Turn the 572F storage adapter over so the components are facing up. Locate the cache directory card D on the 572F storage adapter. The cache directory card is the small rectangular card mounted on the I/O card.

Unseat the connector on the cache directory card by wiggling the two corners that are farthest from the mounting pegs. To disengage the mounting pegs, pivot the cache directory card back over the mounting pegs.
Figure 5. Unseating the connector
Move the cache directory card to the replacement 572F storage adapter and seat it on the connector and mounting pegs.
To reassemble the cards, perform the preceding procedure in reverse order. When connecting the two adapters together, carefully align guide pins B on each side of the interconnect connector A . After the connector is seated correctly, apply pressure to completely squeeze the connector together. To prevent possible card damage, insert all five screws C before tightening any of them.

Cassette installations only: If you are installing the 572F/575C card set adapter into a cassette, perform the following steps:
1. Remove the adapter handle B as shown in Figure 7.

2. If you removed the double-wide PCI adapter from a cassette in the beginning of this procedure, reinstall the adapter into the double-wide cassette to complete the installation. See the procedures in your system unit's service information for installing a double-wide adapter in a double-wide cassette.
Return to the procedure that sent you here. This ends this procedure.
