Replacing Cards
Gracefully upgrade from a Redundant PXM45 Card Set to a Redundant PXM45/C Card Set
To gracefully upgrade from a redundant PXM45 card set to a redundant PXM45/C card set, use the
following procedure:
Step 1 Enter the dspcds command to verify that the current PXM45 card is running Release 4 or later.
Step 2 If you are running CWM on your network, ensure that all workstations are running CWM Release 12.
Step 3 Enter the saveallcnf command to save the existing configuration on the current PXM45 card, and FTP
that configuration file to a remote location. This ensures that you will be able to go back to your old
switch configuration if you need to.
Step 4 Physically remove the standby PXM45 card set (front and back cards) from the switch on which you are
performing the upgrade, and replace it with the PXM45/C card set. Replace the back cards before
replacing the front cards.
Step 5 Log into the switch and configure boot parameters on the new PXM45/C card.
Step 6 Enter the dspcds command and verify that the PXM45/C comes up in the standby-ready state.
Step 7 Enter the switchcc command to witch the roles of the active and standby cards so you can upgrade the
non-upgraded card in standby mode. The PXM45/C now becomes the active card, and the PXM45
becomes the standby card.
Step 8 Enter the dspcds command to verify that the PXM45/C comes up in the active-ready state.
Step 9 Physically remove the standby PXM45 from the switch on which you are performing the upgrade, and
replace it with the PXM45/C.
Step 10 Enter the dspcds command and verify that the standby PXM45/C comes up in the standby-ready state.
Non-gracefully Upgrade a Single PXM45 to a PXM45/C
To non-gracefully upgrade from a single PXM45 to a PXM45/C, use the following procedure:
Step 1 Enter the dspcds command to verify that the current PXM45 card is running Release 4 or later.
Step 2 If you are running CWM on your network, ensure that all workstations are running CWM Release 12.
Step 3 Enter the saveallcnf command to save the existing configuration on the current PXM45 card, and FTP
that configuration file to a remote location. This ensures that you will be able to go back to your old
switch configuration if you need to.
Step 4 Physically remove the PXM45 card set (front and back cards) from the switch on which you are
performing the upgrade, and replace it with the PXM45/C card set.
Step 5 Log into the switch and configure boot parameters on the new PXM45/C card.
Step 6 Enter the dspcds command to verify that the PXM45/C comes up in the active-ready state.
Step 7 FTP the original PXM45 configuration file onto current switch. This is the file that you saved to a remote
location in Step 2.
Step 8 Enter the restoreallcnf command to restore the old configurations on the current switch.
Step 9 Enter the dspcd <slotnumber> command to verify that the reserved front card is a PXM45/C. Replace
<slotnumber> with the slot number of the active PXM45 card.
