I would like to check if it may be possible to hot-upgrade/swap the 4506E power supplies? Based on the configuraton guide; I have summarized the steps as follows:
1. Switch has 2 existing power supplies to be upgraded
2. Remove right side/bay 2 power supply and install new power supply
3. At this point; the new power supply will be in err-disabled due to different power supplies on the switch
4. Remove the left side power supply and install new power supply
For item 4; during the removal of the old power supply in bay 1/left side and installation of the new power supply; I am wondering if the switch would lose power even though the new power supply is installed in bay 2?
The power supplies are hot-swappable. So you will not need to power down the switch to replace or upgrade the power supplies in redundant mode. You can replace one of them, and the switch will continue to run on the original power supply until it is removed, after which the upgraded one will take over.
With dual power supplies running in combined mode, some chassis slots may lose power during an upgrade or power supply replacement.
