Does anyone have experience installing a second(redundant) Sup IV module in a 4507R? Do you remember the steps?
1. Install engine (Hot install or is it better to turn off switch)
2. Configure Switch for redundant operations.
3. Configure for auto-sync or manual sync enginge
4. Is good for IOS versions to match?
How long did it take to complete installation? How much downtime, if any?
Answers to these question or a rough outline would be great
