Step 4 Using the dsprevs and dspcd commands, complete the hardware and software configuration worksheet
in Table 2-8.
Step 5 Compare the versions you noted in Table 2-8 with the latest versions listed in the Release Notes for
Cisco MGX 8850 and MGX 8830 Software Version 3 (PXM45/B and PXM1E).
Step 6 If the switch requires software updates, upgrade the software using the instructions in Appendix A,
“Downloading and Installing Software Upgrades.”
Establishing Redundancy Between Two FRSM12 Cards
To establish redundancy between two FRSM12 cards, use the following procedure.
Step 1 Establish a configuration session using a user name with SUPER_GP privileges or higher.
Step 2 If you have not done so already, set the firmware version for both cards, as described earlier in
“Initializing FRSM12 Cards.”
Step 3 Enter the dspcds command to verify that both FRSM12 cards are in the “Active” state.
Step 4 Enter the addred command as follows:
pop20one.7.PXM.a > addred <redPrimarySlotNum> <redSecondarySlotNum> <redType>
Replace <redPrimarySlotNum> with the slot number of the FRSM12 card that will be the primary card,
and replace <redSecondarySlotNum> with the slot number of the secondary FRSM12 card. Replace
<redType> with the number 1, which selects 1:1 Y-cable redundancy. Although the online help lists other
redundancy types, 1:1 Y-cable redundancy is the only type supported on FRSM12 cards in this release.
Note One of the two cards can be configured before redundancy is established. If this is the case, the
configured card should be specified as the primary card. Redundancy cannot be established if
the secondary card has active lines. If the secondary card has active lines, you must delete all
ports and down all lines before it can be specified as a secondary card. You clear the
configuration on a single service module with the clrsmcnf command.
