Installing a 10GbE card for the C and N interfaces (V20000 on v8.5.3 and higher)
The V20000 G1 appliance also adds the ability to replace the C and N interfaces with 10GbE fiber ports. This requires the P1/P2 and E1/E2 interfaces to be upgraded to 10GbE fiber ports as well. Like the E1 and E2 upgrade, the existing 1GbE copper C and N interfaces on the appliance will be disabled once the fiber card is installed. Note that the riser that holds the fiber cards for the P1/P2 and E1/E2 interfaces must be removed (see previous section) in order to install the fiber card for the C and N interfaces.
