NSTALLATION
To ensure proper installation of the H2TU-C, align the H2TU-C with the enclosure
slot guides and slide the unit in. When the unit is properly seated, the retaining latch
snaps closed.

When the H2TU-C powers up, the four-character display illuminates and reports
status messages.
If the H2TU-C is unable to communicate with the next span device, it displays various
alarm and status messages.
If the unit is able to communicate with the next span device, the following occurs:
1 The Status LED flashes red, while acquiring each device in the system, and turns
steady green when the entire system is operating with no alarms. The DS1 signal
must be present.
The four-character display reports margin (SNR) readings (should be ≥ 6 dB) and
2
loop attenuation (should be <35 dB @196 KHz).
3 Any alarm conditions that exist after the system powers up are reported on the
display. The HLU reports alarms if no DS1 signal is applied.
