• Whether your STRATA TX System contains the optional
AC to DC Power Converter (ACU).
3.3.4 Single TCU Power Up and Power Down
If your STRATA TX System consists of a single TCU, perform the
following steps:
CAUTION
To avoid possible damage, turn off DC
Power on the coax before connecting any
test equipment.
Power Up
1. Verify the power cable is properly connected to the
TCU rear panel POWER connector.
2. Verify all coaxial cables and connectors have been
properly connected.
3. Connect the TCU to DC power of the correct voltage
and polarity.
If you are unsure of the power requirements or the
connections, refer to the “Installation” Chapter on
page 6-1 (Part of the STRATA TX System Technical
Reference Manual only).
If the TCU is powered from the optional STRATA ACU,
connect the ACU input to AC power and verify the
TCU power cable is connected to the ACU DC
OUTPUT connector. Set the ACU power switch to I
(on) and verify the ACU power LED is on.
If the TCU is powered from a source other than an
ACU, turn that power source on.
4. Set the TCU PWR switch to I (on).
5. The normal power-up sequence is as follows:
- The Status LED above the PWR switch should
illuminate and should change colors from red, to
green, to amber, and finally remain green.
- The alphanumeric display should light up and quickly
display a self-test screen, then the version of the
installed firmware, and finally the Main Screen.
Some typical screens are shown in Figure 3-10. The
exact screens will vary depending on installed
hardware.
- The TCU will typically power up using the last settings
in use when power was turned off.
- If the TCU does not power up normally, refer to the
“Troubleshooting” Chapter on page 4-1.
