PURPOSE:
This ECA provides for the replacement of Hot-Swap trays in the
PC Server 704 (8650). These Hot-Swap trays prevent some DDD
and DED errors on IBM 4.51GB half-height hard drives.
This is a MANDATORY EC and must be applied to all affected
4.51GB Hot-Swap drives in the PC Server 704.

PHYSICAL CHECK:
IBM PC Server 704 (8650) systems with the IBM 4.51GB half-height
hard drive FRU P/N 76H4898 (Option P/N 94G6679) are eligible for
this ECA.
DETAIL:
The inspection can be performed without shutting down the Server
and without removing the hard drives. If the trays need to be
replaced, a shutdown will be required; ensure that the customer
has a current backup of all data prior to a shutdown.
Open the front cover and the metal door which covers the
hard drives, and look for hard drives with a serial number label
with the following format: SN xx XXXXXX F8
If F8 appears on a drive AND the tray does NOT have a piece
of foam visible behind the handle, replace the tray with
FRU P/N 75H9031.
Note: The new trays ship with four(4) screws. It is important
to use the new screws along with the new trays.
Although the FRU number has not changed, the trays without foam
have been cleared from stock.
The new trays with foam eliminate hard drive vibration and may
may prevent drives from becoming DDD or DED.
No PC Server 704 systems are manufactured with 4.51GB hard
drives. These hard drives are options only.
All trays manufactured after April 29, 1997 have the foam.
NOTES:
This ECA expires April 30, 1998
IBM/TSS CEs should record all time and parts to Service Code 33,
ECA009, Other Office 990.
