    SRX5600 Services Gateway Interface Card Description

    Interface cards are cards that provide physical interfaces that you use to connect the services gateway to your data network. Three different types of interface cards are available:

    • I/O Cards (IOCs) have fixed interface ports on the front panel of the card.
    • Flex I/O Cards (Flex IOCs) have fixed interface ports on the front panel of the card.
    • I/O Cards (IOCs) have fixed interface ports on the front panel of the card.

    You can install interface cards in any of the slots that are not reserved for SCBs. If a slot is not occupied by a card, you must install a blank panel to shield the empty slot and to allow cooling air to circulate properly through the services gateway.

    I/O cards (IOCs) and Flex IOCs are optimized for Ethernet density and are capable of supporting up to 40 Gigabit Ethernet or four 10-Gigabit Ethernet ports (see Figure 1). The IOC assembly combines packet forwarding and Ethernet interfaces on a single board. The IOCs interface with the power supplies and Switch Control Boards (SCBs).

    Figure 1 shows typical IOCs supported on the services gateway.

    Flex I/O cards (Flex IOCs) are IOCs with two slots, which accept port modules that add Ethernet ports to your services gateway. A Flex IOC with installed port modules functions in the same way as a regular IOC, but allows greater flexibility in adding different types of Ethernet ports to your services gateway. Figure 2 shows a Flex IOC with two typical port modules installed.
