_ DEC-O-LOG for DEMPR

_ DOL, DEMPR-R001, THINWIRE ETHERNET OCT 87

PROBLEM: 1. A shorted coax cable connected to any port
may bring the network performance to zero.  2. Self
test is configured disabled and requires removal of
jumper to enable. 

FIELD EFFECTIVITY: all DEMPR-AA and DEMPR-AB units should
be upgraded to the minimum supported Revision Level of
"C1".  Verify that all FS Stockrooms and SR17 have only
Revision "C1" of higher DEMPRs.  All Thinwire Interim
Revenue Ship (TIRS) Program DEMPRs that are not Revision
Level "C1" will require replacement.  Replacing a Revision
"B1" DEMPR (TIRS) with a Rev. "C1" unit does not require
re-configuration of the network.  This FCO implements ECO
number DEMPR-ML002. 

QUICK CHECK: DEMPR-AA or DEMPR-AB is at Revision Level "C1"
or higher.
