    PHYSICAL ENVIRONMENT Mount the UNITY4000 IRD in a standard EIA 19-inch equipment rack located in a clean, dry environment, and do not place unsupported equipment on the unit. Make sure that total rack power consumption does not exceed the limits of the AC branch circuit, and that a reliable earth safety ground is maintained.

  • Page 12: Security Labels

    Please note the maximum per-unit power dissipation of 45 watts. SECURITY LABELS The UNITY4000 uses security labels over some of the screws. There are no user serviceable components within the unit, and tampering with the security labels or opening the units will void your warranty.

    The control system on the main board is run by the main host processor. This processor interfaces with the COMPEL™ network as well as local users and then controls and monitors the unit’s operations. To do its job, this processor accesses the control data streams recovered from the main transport demultiplexor.

  • Page 29: Section 3 - Operation

    SECTION 3 OPERATION MODES OF OPERATION 3.1.1 Power Up At power up, the unit does a quick checksum test on the EEPROM. If the test passes, the unit then initializes various devices and configures itself according to the EEPROM settings. It then waits for the receiver board to complete its power up tests, which takes about 10 seconds.
