UCN node number
When displaying the UCN node number, it is important to realize that the HPMM has no concept of
redundancy while in the Alive, Loading, or Fail state. Therefore, at best, the HPMM knows the user
configured UCN node number (pinned odd address only) and the physical card file number (pinned), and
whether it resides in a 7 or 15 slot HPM backpanel. This information produces the following methods of
uniquely displaying a UCN node number at all times.
Fnn
nn
represents the user configured decimal UCN node number (01-64) preceded by a physical
position indicator during the Alive, Loading. and Fail HPM states.
The actual physical position indicators are represented as “L” and “R” to indicate residency in a 7-
Slot card file and “1” and “2” to indicate residency in the file-1 and file-2 15-Slot
backpanels.Although this information is inconsistent when viewed from the LCN, it eliminates the
ambiguity of having another HPMM node in the Alive, Loading, or Fail state display the identical
UCN node number of its redundant partner in the Idle or OK state.
nn
nn
represents the decimal UCN node number (01-64) during normal HPMM Runtime
operation. The primary (or nonredundant configured) HPMM node displays the user configured
odd node address, and the secondary HPMM, if configured and loaded, displays the even node
address. This is consistent with the information that is viewed from the LCN.
Format descriptions
Using the UCN node number conventions described on the previous page, the alphanumeric display
formats are described in the following table.
Table 65 Alphanumeric Display Formats
Condition
Format
Description
Afnn
A = Alive
f = actual physical position indicators (as “L” and “R” to indicate residency in a 7-Slot
card file
and “1” and “2” to indicate residency in the file-1 and file-2 15-Slot
backpanels)
nn = user configured decimal UCN node number (01-64)
Indicates the successful Cold startup of the HPMM Communications processor. In this
state the Communications processor loops indefinitely while performing background
diagnostics and waiting for a UCN download to occur. The Control processor and I/O
Link processor are held initialized. This display message blinks at a 1/2 second rate to
indicate the Communications processor is still running.
Backup State
B nn
Indicates the personalities of the Communications, Control, and I/O Link processors
have been loaded into the secondary HPMM, or the primary HPMM has successfully
transitioned to the synchronized secondary status. This display does not blink.
Backup Soft
Fail State
BSnn
Indicates that the HPMM has transitioned to the Backup Soft Fail state.
