Problems During Machine, EC, or MES Installation
When installing a 3745, the
3745 Installation Guide
, SY33-2067 should be used. When installing an EC or
an MES, the supplied instructions should be used. It is possible that the task or diagnostic you were
asked to perform during the installation detected an error, and you were requested to start troubleshooting
using this manual.
The primary purpose of this manual is to resolve problems that occur in an operational environment after a
successful installation. That is, the machine has worked previously and is now failing.
At installation time, or after an EC or MES is installed, it is possible that errors may occur due to condi-
tions which would not exist in an operational environment.
Cables plugged incorrectly
Terminators missing
Mismatch between CDF and machine configuration
Mismatch between line characteristics and setups
Wrong address set
Top card connectors incorrectly installed
Loose cards.
During your path through the MIP, you should remember these possibilities and, when the failing area is
identified, check with the aid of the
3745 Hardware Maintenance Reference
, SY33-2066 and YZ pages
that these conditions do not exist prior to changing FRUs.
Now, starting at the top of the “Selection Table,” work down until you find an entry that matches the
symptom detected during the installation.
Be sure to read “Exchange Precautions” on page 4-1 before removing any FRUs from this
machine.
