--------------
! NOTE: This FCO is officially taken off HOLD as the reasons for placing it
	on hold have been resolved, ie;
	
	1. The affected shipment end date has been confirmed, and changed from
	   September 17, 2001 to August 31, 2002.
	   
	2. Previous Customer Lists were confirmed to be complete with the 
	   exception of missing 47 affected RTS units shipped in Sun Fire
	   Cabinets.  A third customer list has been added to show these
	   additional affected shipments.


Sun Fire 3800/4800/4810/6800 systems will not fail over.  An extended outage
may occur on Serengeti systems due to a weak fuse in the standby Redundant
Transfer Switch (RTS) that blows when the AC load from the primary RTS is
switched over.

In some cases the standby RTS is functionally dead, but the Green LED
remains "on" as a result of power supplied by the primary (live) RTS.

Many Serengeti systems shipped on or before August 31, 2002 may be affected.
Three customer lists, and a Customer Letter are provided below to aid in the
location and communication of this issue to affected customers.  These lists
only show systems and cabinet that contain affected RTS units as shipped
from Sun Manufacturing.

Root cause determined that the 1 amp fuse (F3) in the Redundant
Transfer Switch was of poor quality and would blow during the power
transfer step from power grid 1 to power grid 2 (common mode).  This
fuse is soldered onto the RTS module PCB, and is not replaceable in the
field.

Corrective action was made available in Manufacturing by phasing in a 2
amp fuse in the 300-1396-05 as of September 18, 2001.  Therefore some
-05 RTS units have a 1 amp fuse and some have a 2 amp fuse.  RTS units
with a serial number of 20557 (or above) or with a date code of 0136
(or later) will have the good (2 amp) fuse.  An example of a good RTS
serial number is 000025-0135A20559.

This corrective action was officially made available via ECO# WO_23761
on October 15, 2002 by dash rolling part number 300-1396-05 to -06.
Corrective action was made available in Sun Services via LEAP 2151 on
January 8, 2003.

o To determine if a system or cabinet is affected:

There are no software commands for determining whether a system has
an affected RTS or not.

1. First refer to the above Customer Lists which contain affected system
   and cabinet serial numbers as well as affected RTS serial numbers.
   
2. Remove the RTS units one at a time and check part number and
   serial number.
   
   . If the part number is 300-1396-04 it is affected and should be replaced.
   . If the part number is 300-1396-05 it may be affected and the date code
     and serial number must be checked.  If RTS date code is 0135 or earlier
     AND the serial number is 20556 or below, the RTS is affected and should
     be replaced.  If the RTS serial number is 20557 or above it is good, and
     no replacement is necessary.
   . If the part number is 300-1396-06 or above it is not affected and
     no replacement is necessary.

How to read an RTS date code / serial number:

  0000025-0135A16445
        \\ \\\\\\\\\\_  5 digit unique Serial Number
         \\ \\\\\______  A = Assembly Code
          \\ \\\\_______  4 digit date code yyww
           \\		 (0135 = week 35 of 2001)
            \\___________ 25 = Vendor Code

The above example is affected and should be replaced.

When the RTS is repaired, the date code and the serial number (last 5 digits)
will remain the same but the part number dash level will be rolled to -06.

Note: There is no correlation between date code and the actual
      shipment timeframe of a system.  Therefore an RTS could have
      a date code of 0132, but could have shipped in the year 2002.

The following pictures should aid in the visual inspection of RTS modules:

Parts Affected: 

April 30, 2004

Implementation: 

---
| X |   MANDATORY (Fully Pro-Active)
 ---

 ---
|   |   CONTROLLED PRO-ACTIVE (per Sun Geo Plan)
 ---

 ---
|   |   UPON FAILURE
 ---

Replacement Time Estimate: 

1.5 hours

Special Considerations: 

IMPORTANT: In the Americas, field personnel MUST contact their Area TPM to
           schedule and prioritize parts ordering relative to the implementation
           of this FCO.

The RTS can be hot-swapped, with no down time for customers having dual
RTS modules (or a loaner RTS) and available power.  There is a small risk
of an outage that a hot swap will fail, resulting in a system outage.
This is described further in the replacement instructions listed in the
Corrective Action section below.

The following is a replacement time estimate for systems having only
one RTS module, where no loaner RTS is available;

  10 min shutdown operating system(s)
  15 min replace RTS module
  40 min powerup and setkey on all domains (in parallel)
  15 min boot up operating system(s)
  --
  80 minutes total

Corrective Action: 

Proactively replace all 300-1396-04 units, or any 300-1396-05 with
date code of 0135 or earlier AND serial number earlier than 20557, with
300-1396-06 (or above) in all affected systems and cabinets.

The dash level of the RTS can only be checked visually by removing
the RTS module from the system and viewing the part number label
on the side that plugs into the Redundant Transfer Unit (Ref:
MVC-005F.JPG picture link above).

The following is provided as an aid in replacing the RTS module:

 The RTS modules are most readily replaced with the system powered down,
 as described in 806-4716-11 RTS Installation Manual.

 It is possible to replace RTS modules while the system is running,
 at the risk of a system outage should one of the replacement modules
 fail upon installation.  Additionally, if RTS modules are being
 replaced in an RTU enclosure containing two RTS modules, it is possible
 that the primary RTS module will have the blown fuse that this FCO
 addresses, and that this active module will fail when the secondary
 RTS module is switched off. For RTU enclosures with two RTS modules,
 it is safer to replace the RTS modules during system down time.

 If there is only one RTS module in a Redundant Transfer Unit (RTU)
 enclosure, it is possible to install a loaner RTS module into the empty
 slot, power it up with the switch on the front of the RTS module and
 wait for the leftmost green lamp to come on.  Next, turn off the switch
 on the primary RTS module, which (with a loud snap) will then failover
 to the loaner RTS, which has become the primary module.  The primary RTS
 module is identified by two green LEDs.  The secondary RTS module has
 just the leftmost green LED lit.

 Care must be taken to ensure that any devices plugged into the unswitched
 outlets associated with a particular RTS (J11 for the left side RTS unit,
 J12 for the right side unit) have an additional power source.  The J11
 and J12 outlets are typically used to provide power to the rack fan trays.
 The rack fan trays provide power to the frame manager, which will continue
 to run so long as one of the rack fan trays is on.

 When RTU power has transferred over to the loaner RTS, the remaining RTS
 can be replaced.  When the new RTS is powered on and its leftmost LED
 is lit, the loaner RTS can be powered off and removed.

 The RTS modules are designed to favor the leftmost RTS.  When both RTS
 modules are powered on and healthy, the leftmost module will eventually
 become the primary module (the one with two green LEDs lit), with the
 rightmost RTS module supplying power to only the J12 unswitched outlet
 on the RTU.

 If both RTS modules are present, the secondary module may be switched off
 and replaced, and then the other one, as above.
