The System Inventory screen lists the six possible units that can comprise one HiGain circuit: one ELU, one ERU
and up to three doublers. The information in the System Inventory Screen is presented as follows:
•
All six possible unit modules are always listed. The doublers are shown as: DB1, DB2, and DB3.
•
The model number, list number and software revision number of every unit that is present in the circuit is
listed in the Product column. Units that are not detected are not considered to be present in the circuit and are
labeled N/A.
•
Each of the unit IDs is limited to 24-character alphanumeric characters. To change an ID, select its line
identifying letter. The IDs, like the system settings, are stored in NVRAM and remain so when power is lost.
•
The ELU has no unit ID number since it is usually identified by the Circuit ID number, which appears in every
screen.
•
All detected modules have the product number listed. Whenever the ELU-319 loses sync with Span 1, the
product types are replaced by the N/A label until sync is reestablished and each module can in turn be
reidentified. Only the Circuit ID appears in the other ELU-319 List 5E and List 6E
Terminal Maintenance screens.
