_ DEC-O-LOG for TA91 _ DOL, TA91-S001, Tape Drive, Apr 93 FIELD EFFECTIVITY: This "S" coded FCO must be installed on all TA91X-AA, TA91X-BA, TU91-BA, TU91-DA and TU91U-DA options. This FCO incorporates ECO TA91-SH003 and changes the revision of the TA91-AA/BA to "D01", TU91BA/DA to "C01" and TU91-DA/EA to "D01". All field spares should also be upgraded with this FCO. PROBLEM: It is possible to break connector J11 on the 60Hz power supply. Breakage of the connector can occur if the connector cable is pulled on without releasing the connector locks. If this occurs, a potential safety hazard exists if the detached (broken) cable, which carries 208vac, makes contact with the power supply frame or with service personnel. SOLUTION: Retrofit the power supply using a pair of plastic connector braces. QUICK CHECK: The opening in the power supply chassis where J11 connects should have a pair of plastic connector braces installed or the power supply vpn is 61G8657.
