Table A-2 Upgrade Options
Option Used when... Steps
Y-Red BXMs,
manual Legacy BXMs are Y-red
and the “auto BXM
upgrade parameter” is
set to “N” for the
cnfnodeparm
command.
1.
Remove the standby BXM card and replace it with the BXM-E card.
2. BXM-E card scan be flagged as “Mismatch” if the configured channel
statistics level or number of connections is smaller than those configured on
the active BXM card. Use the command
cnfcdparm <BXM-E slot_num> to
configure the desired level of channel statistics and number of connections,
if not already configured. The BXM-E card is reset after the
cnfcdparm
command is executed. After the BXM-E card boots, there should be no
mismatch.
3.
Y-red the switch so that the standby BXM-E becomes active.
4. Repeat steps 1-2 for the other slot. You still can fall back to the legacy card
up to this point.
5.
Upgrade the logical card using the command upgdlogcd <log_card_num>.
Switch software upgrades the logical database from the number of
connections configured on the legacy BXM card to the number of
connections configured in step 2 and 4. From this point on, mismatch is
declared if the legacy card is reinserted.
Note
During upgrading Y-red BXM cards to BXM-E cards, the level of service
disruption is expected to be the same as the one experienced when
switchyred is executed for Y-red legacy BXMs.
