Instructions for Installing the Module
To install the 3192 H4TU-C, perform the following
steps:
1. If present, remove the Access Module Blank from
the appropriate access module slot of the HDSL4
chassis.
2. Hold the 3192 H4TU-C by the front panel while
supporting the bottom edge of the module.
3. Align the module edges to fit in the lower and
upper guide grooves for the access module slot.
4. Slide the module into the access module slot.
Simultaneous thumb pressure at the top and at the
bottom of the module will ensure that the module is
firmly positioned against the backplane of the
chassis.
When the 3192 H4TU-C first powers up, it runs the
power up self-tests. Once the power up self-test is
complete, the status LEDs will reflect the true state of
the hardware.
Front Panel LEDs
LED indicators mounted on the front panel of the unit
provide the status of the HDSL circuit. See
a listing of the front panel LEDs and their indications.
