HLU-388 List 5A September 15, 1999 37
System Inventory Screen
The System Inventory screen ( Figure 19 on page 38 ) lists the six possible units that can comprise one HiGain
circuit: one HLU, one HRU and up to four 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, DB3, DB4.
• 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
. When the HLU-388 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.
• Each description in the Product column is limited to 24 alpha-numeric characters. To change a description,
select its identifying letter. The descriptions, like the system settings, are stored in NVRAM and therefore
remain when power is lost.
• The System Inventory screen displays HiGain unit serial numbers. For HLU-388 List 5A units manufactured
prior to August 5, 1999, the screen displays only the last six digits of the serial number. Those HLUs
manufactured after that date display all ten digits.
• The HLU requires no unit ID number since it is usually identified by the Circuit ID number.
Press at the Maintenance Terminal Main Menu to display the System Inventory screen ( Figure 18 and Figure 19
on page 38 ).
From each System Inventory screen (depending on the number of doublers), you can do the following:
1 Select the unit for which you want to set the circuit ID by pressing the letter that precedes the unit name.
2 Type the circuit ID, then press .
You can use up to 24 alphanumeric characters for the circuit ID. If more than 24 characters are entered, a
warning beep is emitted and only the first 24 characters are accepted.
3 To set the circuit ID for another unit, repeat Step 1 and Step 2 .
4 Press to exit the System Inventory screen.
The system prompts you to confirm the circuit ID.
5 Press to confirm the circuit ID and exit the System Inventory screen.
Executing the default option from either the front panel or System Settings screen has no effect
on the ID values.
