Appendix A Upgrade Information
Upgrade Options
Stand alone
BXM, manual Legacy BXM card is
non-yred and the “auto
BXM upgrade”
parameter is set to “N”
for the cnfnodeparm
command. 1. Use an empty slot to configure the BXM-E card for the desired level of
channel statistics and number of connections. The channel statistics level
and number of connections must be either equal to or higher than the ones
configured on the legacy BXM card that it is replacing. While this step is
optional, if skipped, the BXM-E card may not have the desired channel
statistics level and appropriate number of connections.
2.
Remove the BXM card and replace it with the BXM-E card. If step 1 is
skipped, the BXM-E card can create a mismatch if it does not have the
desired configuration. In that case, use the command cnfcdparm <BXM-E
slot_num> to set the card to the desired level of channel statistics and
number of connections. This may prolong service disruption.
3. Issue the upgdlogcd <log_card_num> command to upgrade the logical card
database. 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 1. From this point on, mismatch is declared
if the legacy card is reinserted.
Note In non-yred cases, the traffic disruption is unavoidable
because the legacy BXM has to be removed and replaced
with the BXM-E card.
Stand alone
BXM,
automatic Legacy BXM card is
non-yred and the “auto
BXM upgrade”
parameter is set to ‘Y’
for the cnfnodeparm
command.
1.
Use an empty slot to configure the BXM-E card for the desired level of
channel statistics and number of connections. The channel statistics level
and number of connections must be either equal to or higher than the ones
configured on the legacy BXM card that it is replacing. While this step is
optional, if skipped, the BXM-E card may not have the desired channel
statistics level and appropriate number of connections.
2. Remove the BXM card and replace it with the BXM-E card. If step 1 is
skipped, the BXM-E card can create a mismatch if it does not have the
desired configuration. In that case, use the command cnfcdparm <BXM-E
slot_num> to set the card to the desired level of channel statistics and
number of connections. This may prolong service disruption.
3.
Switch software automatically upgrades the logical database when step 2 is
done.
Note
In non-yred cases, the traffic disruption is unavoidable
because the legacy BXM has to be removed and replaced
with the BXM-E card.
