LTPH-UM-1234-01 Installation

1To install the doubler unit, slide the doubler unit into the card guides for the desired slot (see Figure 5 on page 20).

2Next, push the unit into the enclosure until it is seated in the card-edge connector. The unit snaps into place, indicating that it is properly seated.

Once the HDU-409 is installed in the enclosure, the front panel Status LED flashes green to indicate power is applied from an upstream line unit. When the loops on both sides of the HDU synchronize, the LED is steady green.

Refer to Table 2 on page 5 for more details on LED operations.
