 Abstract:  ECA017, DECREASED NETWORK PERFORMANCE USING 100MBS ETHERNE  T


 PURPOSE:
 The purpose of this ECA is to correct a possible reduction
 of network performance when using the integrated 10/100
 Ethernet adapter at a rate of 100mbs.

 PHYSICAL CHECK:
 Affected systems are limited to IBM PC300XL Series 6588 and
 IBM IntelliStation M-Pro Series 6888 systems equipped with
 an integrated Intel 10/100 PCI Wake-On-Lan Ethernet adapter.

 PREREQUISITES:
 None

 COMPANION:
 None

 CONCURRENT:
 None

 DETAIL:
 The error, or reduction of network performance condition
 is only seen when using the integrated Ethernet adapter.
 OEM ISA and PCI Ethernet network adapters are not affected.

 Systems may return various networking error messages, or
 exhibit increased packet loss during transfers.

 The reduction of network performance condition may be exper-
 ienced under various operating systems, and is typically
 limited to networking cable lengths equal to, or exceeding
 50 meters (150 feet).

 NOTES:
 Before replacing hardware, proceed with normal problem
 determination to eliminate possible software configuration,
 network cabling, or network equipment errors.

 If error messages, or network performance conditions
 persist (i.e. increased packet loss during transfers),
 replace the system board with FRU P/N07L9076.

 This ECA will expire on December 31, 2000.
