Instructions for Installing the 3192 HTU-C
To install the 3192 HTU-C, perform the following steps:
1. Hold the 3192 HTU-C by the front panel while supporting its bottom edge to engage the
chassis edge.
2. Align the 3192 HTU-C edges to fit in the lower and upper guide grooves for the module
slot.
3. Slide the 3192 HTU-C into the module slot. Simultaneous thumb pressure at the top
(above the
DSL1
LED) and at the bottom (below the electrostatic caution symbol) of the
3192 HTU-C will ensure that it is firmly positioned against the backplane of the chassis.
When the 3192 HTU-C first powers up it runs the power up self-tests. Once the power up self-
tests are complete, the status LEDs reflect the true state of the hardware.
