For RISLU using DFI with FE mode, the maximum number of ports per PSU shelf is 96. This number
includes all packet switch ports beside ACD/OSPS positions.

Identify time slots which are currently assigned to the RISLU by reviewing RC/V 22.19 where LU field
indicates the RISLU unit number to be converted.
The total number of fully assigned time slots for the RISLU (RC/V 22.19 ST field indicates F) must be
less than or equal to the number of empty (or unused) time slots (RC/V 22.19 ST field indicates N) on
the same PSU shelf. If the total number of fully assigned time slots is greater than the number of empty
time slots, then ONE port from each of the FULL time slots must be degrown or deleted until the number
of FULL time slots is equal to the number of empty time slots (by checking with RC/V 22.19 after each
port is deleted) prior to the conversion.
The previous action would greatly reduce the chance of failure when updating RC/V view 22.9 during the
RISLU conversion.
Table 11.6-2 summarizes the previous discussion.

NOTE: At most, only ONE port belonging to each fully assigned time slot (time slot with ST field equals to F
for the PSU shelf in RC/V view 22.19) of the ACD/OSPS RISLU to be converted, will need to be
degrown per PSIUPIDB time slot.
The removed ports can be reinserted to the same RISLU after the conversion providing that there are
available empty or partially full time slots on the PSIUPIDB (by reading relation rlDGRP_RI again).
11.6.2.9 Post-Conversion
1. If some ports were degrown prior to the conversion, the following steps may be used to reinsert the ports
after a successful conversion providing that the PSU time slot pool is not exhausted.
NOTE: The reinsert work may include physical hardware movement of RISLU LCs to other positions.
(A) Time Slot Available Verifications
Collect the "post-conversion" PSU time slots data using Section 11.65.2.2.3. The following restrictions
must be met before degrown ports can be re-inserted. If the data indicates otherwise, hardware
addition (PSU shelf or PH) may be needed to add more RISLU port.
For 5E9(1) and 5E9(2) software releases:

Verify that (PSIUPIDB.sh_ts_nailup - PSIUPIDB.rpa_ts) is less than 32.
