Operations Manual: Operations
Engineered to Endure
• Checking the disconnect devices such as the circuit breaker.
• Checking the fuses.
•
For DC-powered IBUCs, the fuses are in the power supply.
•
For AC-powered IBUCs, the fuses are in the IBUC.
Fuses are 5x20 mm time-lag glass body cartridge type.
Time Stamp Data is Incorrect
Note:
This only applies if the customer is not using NTP.
The time stamp on the alarm log may be incorrect after the IBUC has lost power for an
extended period. In such cases you can set the system date and time by using the
provided CLI commands. To correct Time Stamp Data,
1. Open Terminal session using either RS232 or SSHv2 , described in Chapter 5,
Monitor and Control Features and login or by the steps provided in Appendix B,
Embedded Web Pages .
2. Check whether the IBUC time zone is correctly configured via command TZO on
page C - 47 .
3. Configure IBUC Real Time Clock via command CTM on page C - 21 .

appears to
be transmitting a signal, but the satellite network operations center (NOC) cannot
identify your carrier.
To determine whether your settings are correct,
1. Verify that your frequency is within the bandwidth slot that was allocated to you.
2. Determine whether the IBUC operates with the LO on the low side or the high side
of the frequency that was allocated to you.
3. Check the signal mix. Remember that low-side is non-inverting and high-side is
inverting.

WARNING
Before applying power to the unit, ensure that the waveguide output is
properly terminated. Failure todo so could lead to serious personal injury,
excessive RF radiation levels, and equipment damage.
