1.2 Changes Since the Previous Release


ATTENTION

Always flash the Level-A PROM when upgrading CSM software. This is especially important when upgrading from CSM V1.4.1 or earlier to CSM V1.5 or later. Serious problems can result if the Level-A and Level-B versions do not match. Beginning with CSM V1.6.0, a warning message is displayed if the Level-A and Level-B versions do not match. This situation is likely to occur when replacing a CSM board.

After correcting a mismatch, you may need to erase the NVRAM and install the factory default NVRAM settlings using the ram scrub command. Be sure to write down any customized NVRAM data before performing the scrub so that you can re-enter the data after the scrub.

Refer to Appendix A for instructions about flashing PROMs.


Version 1.6.1 includes all the functionality of Version 1.6 for S5000 and WS5000 systems plus the following new features:
