ECA 068 - P70 - 121/161
8573 mod 061 + 121 fails to load AIX, UNIX or ZENIX
PURPOSE:
To correct system HANG problems when loading AIX, UNIX or ZENIX
operating systems to the Fixed Disk by replacing the down
level bus interface assembly P/N 65X1567.
Machines AFFECTED
8573 mod 061 below 50000
8573 mod 121 below 50000
PHYSICAL check:
Check bus interface assembly P/N 65x1567 for a 1000mF capacitor installed
on the bottom of the card. The capacitor is the only electronic component
on the card. If an option card is installed in the lower connector it may be
necessary to remove the card to view the capacitor.
NOTE:
When using the HMR for removal and replacement procedures, the bus interface
assembly is referred to as the option connector assembly.
DETAIL:
This ECA provides for the replacement of bus interface assemblies not
having a capacitor present on the connector card. current level bus interface
assemblies have the capacitor on the bus connector card eliminating a data
transfer noise that can prevent loading AIX, UNIX or ZENIX operating systems
to the fixed disk.
NOTEs:
Order P/N 65X1567 through normal distribution.
