H091076 - ECA009, PC SERVER 704 HOT-SWAP TRAY REPLACEMENT 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. FEATURES: Type, Machines Affected Model, With and/or Feature/Device B/M to be Service System Stage B/M Description Installed Hours Hours 8650 B/M0000000 PC SERVER 704 WITH B/M0000000 01.0 00.8 4.51GB IBM 1/2 HEIGHT IBM HARD DRIVE OPTIONS PHYSICAL CHECK: IBM PC Server 704 (8650) systems with the IBM 4.51GB half-height hard drive FRU p/n76H4898 (Option p/n94G6679) are eligible for this ECA. PREREQUISITES: NONE COMPANION: NONE CONCURRENT: NONE 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/n75H9031. 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. April 29, 1997
