I am planning to upgrade a pair of 4506-E SUP 8-E supervisors in VSS mode to 3.8.6E with WS-X4748 UPOE line cards- The release notes state the following
Manual Field Programmable Gate Array Upgrades
If you have installed WS-X4748-UPOE in the chassis, note the following:
With Cisco IOS XE Release 3.8.xE, after an ISSU upgrade, you may have to manually upgrade the Field Programmable Gate Array (FPGA) for WS-X4748-UPOE+E line cards that have version ID (VID) 03 or later versions. (To check the VID, enter the show inventory command in privileged EXEC mode).
The required FPGA upgrades are not triggered automatically after an ISSU upgrade. This may result in an unexpected FPGA upgrade of all applicable linecards if a linecard is inserted online (OIR), after ISSU upgrade. The solution to this problem is to manually perform an FPGA upgrade during a maintenance window.
Follow these steps for all WS-X4748-UPOE+E linecards in the chassis:
Switch(config)# service internal
Switch(config)# end
Switch# hw-module module-number upgrade-fpga-all
Anyone got any experience of doing this? Any known gotcha's?
I presume I have to do this twice once for line card in the active switch and once for the card in the standby switch using the virtual switch mapping slot.
