Use this procedure to separate the 571F/575B card set and
to move the cache directory card.
To complete this procedure, you need a special bit or driver
(T-10 TORX).
Attention: To avoid loss of cache data, do not
remove the cache battery during this procedure.
To separate
the 571F/575B card set and to move the cache directory card, complete
the following steps:
Important: All cards are sensitive
to electrostatic discharge.
- Label both sides of the card before separating them.
- Go to the next step if you are not servicing a 571F/575B
card set containing a light pipe assembly. If you are servicing a
571F/575B card set that contains a light pipe assembly, you will need
to remove the light pipes. To remove the light pipes, do the following:
- Place the 571F/575B card set adapter on an electrostatic discharge
(ESD) protective surface.
- Remove the light pipe retaining screw (C) from the 571F/575B
card set.
- Slide the light pipe assembly (D) from between the 571F/575B
cards.
- Put both the screw and the light pipe assembly in a safe place.
- Place the 571F/575B card set adapter on an ESD protective
surface and orient it as shown in the following figure.
- Disconnect battery cable (A) and
the SCSI cable (B) from the 571F storage adapter.
Leave the other end of the cables attached to the 575B auxiliary
cache adapter.
- To prevent possible card damage, first loosen
all five retaining screws (C) before removing
them. After all five retaining screws have been loosened, remove
the screws (C) from the 571F storage adapter.
- Carefully lift the 571F storage adapter off the standoffs
and set it on the ESD protective surface.
- Turn the 571F storage adapter over so that the components
are facing up, and locate the cache directory card (D) on
the 571F storage adapter. It 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
peg.
- Move the cache directory card to the replacement 571F storage
adapter and seat it on the connector and mounting pegs.
- To reassemble the cards, perform steps 1 - 9 in reverse
order. To prevent possible card damage, insert all five screws (C) before
tightening any of them.
Note: If you are installing the
571F/575B card set adapter into a cassette, do the following steps:
- Remove the adapter handle (B) as shown in the following
figure.
- If applicable, remove the light-pipe assembly.
- Remove the two plastic covers from the Small Computer Systems
Interface (SCSI) jumper cable (A) as shown in the following
figure.
- Ensure that the battery cable (A) and the
SCSI cable (B) are reconnected to the 575B
auxiliary cache adapter.
- Place an adapter in the PCI adapter double-wide cassette to complete
the installation.
- If applicable, to replace the light pipes, do the following
steps:
- Ensure that the 571F/575B cards are correctly assembled.
- If necessary, remove the 571F/575B card handle (A) from
the back of the card set.
- Slide the light pipe assembly (D) between the 571F/575B
cards. Ensure that the threaded screw hole located on the light pipe
assembly is aligned with the screw clearance hole located on the card.
- Return to the procedure that sent you here. This ends
this procedure.
