Juniper SRX5K-4XGE-XFP Internal Ethernet networking card

4x10 Gigabit XFP Ethernet I/O Card for SRX 5000, no transceivers The I/O Cards (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, with four 10-Gbps Packet Forwarding Engines. Each Packet Forwarding Engine consists of one I-chip for Layer 3 processing and one Layer 2 network processor. The IOCs interface with the power supplies and Switch Control Boards (SCBs).

You can install IOCs in any of the slots 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.
