1. On optical cards, each port has separate connectors for the transmit (Tx) and receive (Rx) circuits.
2. The low-density version of a card provides a limited number of ports that are enabled through software entitlement.
3. Protection features for various types of cards and ports depend on the release of the SmartEdge OS; the system supports a mix of protected and unprotected
ports.
4. The 20-port GE1020 card requires two adjacent slots.
