1. Can I have no downtime to do this activity ? As per Cisco HW installation guide, It seems I should replace 2 SUP at same time, but if I can replace separately, please let me know. - Replacing supervisors will have downtime as you need to move hardware physically in and out of chassis.
2. How many minute is required for upgrade EPLD with above HW inventory ? I assummed this time about 1hr ~ 90 min(max), is it correct ? - Once the supervisor is upgraded, you may upgrade all the modules parallely so considering the boot time of all these modules you are in safe limit.
3. If this upgrade is failed, then I need to rollback from SUP2E(S2-6.1.2) to original SUP1(S1-6.1.1). Is below step is correct for rollback ? - Indeed its correct.
4. when I downgrade to n7000-s1-epld-6.1.1a, only linecard will be downgrade > or All SUP and FAN or Power module EPLD also downgrade ? If so, how many minute will re required with previous HW inventory ? I assummed this time about 40 ~ 60 min(max), is it correct ? - Check this:
