Things to be considered before upgrading an IOS in a Cisco 6500 Series Switch with SUP720- Series 3

In the second series I  was talking about the Compact flash memory, now let’s proceed further, one more key thing you must consider before starting an IOS upgrade for a Cisco Catalyst 6513 Switch with Supervisor Engine SUP720 is the redundant power supply.  Make sure the Cisco Catalyst 6513 Switch is installed with the redundant power supply and they are connected to two different power sources.  Suppose one power source fails then the other source can take care of the Cisco Catalyst 6513 Switch while the IOS upgrade is going on.
