TLA721 Benchtop & TLA7XM Expansion Mainframe Service Manual

Troubleshoot the Expansion Mainframe

Because the expansion mainframe adds a level of complexity to troubleshooting
problems, this section will concentrate on tips to aid you in troubleshooting
expansion mainframe related problems.

There are certain signs that the expansion mainframe is not powering-on
correctly. By looking and listening you can determine if the expansion main-
frame is not powering-on because the expansion mainframe is not receiving a
signal from the expansion module.

Upon powering-on the benchtop mainframe (or portable mainframe), the
expansion module in the benchtop mainframe sends a signal, to the expansion
module in the expansion mainframe via the three expansion cables. If the
expansion mainframe does not receive this signal, the expansion mainframe will
not be prompted to power-on.

If the expansion mainframe receives the power-on signal the fan will start and
the lamp on the mainframe will light. Further indications that the mainframe is
receiving signals from the expansion module is that the lights on the expansion
module and any other installed modules will blink, indicating that signals are
being received.

If you have available a known good expansion module, complete the following
steps:

1.

Remove the suspect expansion module from the expansion mainframe. The
expansion module is a Slot 0 device when installed in the expansion
mainframe. Verify that the expansion module is installed in Slot 0 and that
the MODID switches on the back of the module are set to FF.

2.

Try swapping the expansion module from the benchtop mainframe (or
portable mainframe) with the expansion module from the expansion chassis.
This sometimes works because one module is a sender while the other
module is a receiver.

CAUTION.

The single-wide expansion module requires up to 60 lbs. of insertion

force to engage it into the back plane. Do not use the mounting screws to engage
the module into the backplane of the mainframe.

The mounting screws will not provide enough force to seat the expansion
module, and you can easily be strip the threads.

3.

Power-on the mainframe and check for normal operation.

Check the Power-on

Sequence

Substitute a Known Good

Expansion Module
