CHAPTER 4 MAINTENANCE AND TROUBLESHOOTING

4.1 Maintenance

Maintenance of the Unity 4600 is limited to keeping the chassis clean and ensuring that cables remain firmly connected. Occasionally wipe the exterior with a soft, damp cloth to remove any accumulated dust and dirt and check that cables are securely attached.

The Unity 4600 incorporates security labels over some of the screws. There are no user-serviceable components within the Unity 4600. Tampering with the security labels or opening the unit will void your warranty. If you have any questions, contact Wegener’s Customer Service Department at the address or numbers listed under Customer Service.

4.2 General Troubleshooting

No output or indications

No audio, video, or ASI output

This section is not intended as an exhaustive list of all possible situations, but a list of the most common installation problems. Please contact us (see Chapter 5, Customer Service), with any problems you cannot resolve independently.

If you are experiencing any difficulties, first check the LED indicators on the Unity 4600 front panel. See Table 3.2: Front-panel LED Indicator Descriptions on page 33 for details about the LED indicators. Note that during typical operation, the green CARRIER, TRANSPORT, COMPEL, SERVICES, and AUTH LEDS should be on.

If the unit provides no output and neither the LCD nor any LEDs are lit, there is likely a loss of AC power or the internal power supply has failed. Do the following:

1.Check that AC power cord is firmly connected at both ends.

2.Check that your AC power source is supplying AC power.

3.If both checks a) and b) are okay, contact Customer Service (see Chapter 5) before returning the unit for service.

LEDS: ALARM ON and CARRIER OFF

The Unity 4600 is unable to lock to an RF carrier at the selected RF port:

1.If the first front-panel alarm message is "No RF Signal", then: (1) either the outdoor antenna LNB is not operating or is not connected to the IRD at the selected RF port; or (2) the selected IRD RF port has failed; or (3) the IRD receiver card has failed. To rule out (1), verify that the LNB (and any intermediate line amplifiers) has DC power and trace the connection from the LNB to the IRD or try replacing the LNB. If a spectrum analyzer is available, look for the carrier at the L-band intermediate
