A network engineer is doing software updates on a C9010 chassis and Port Extenders. The engineer updates the Operating System and boot flash images. Some PoE ports are NOT working. The engineer needs to complete the following updates so that all PoE ports work.
-PoE Controller
-FPGA
-
CPLD
In which order should the engineer complete the updates so that all PoE ports work?
A.
1. Upgrade the PoE Controller.2. Upgrade the CPLD image on attached PEs.3. Upgrade the FPGA and CPLD images on C9010 RPMs and line cards.
B.
1. Upgrade the PoE Controller on attached PEs.2. Upgrade the FPGA and CPLD images on C9010 RPMs and line cards.3. Upgrade the CPLD image on attached PEs.
C.
