I/O Card SRX5K-4XGE-XFP Specifications

The SRX5K-4XGE-XFP I/O card (IOC) supports four 10-Gigabit Ethernet ports (see Figure 8). 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 must install at least one IOC in the services gateway. The IOC can be of any of the available IOC or Flex IOC types.

You can install IOCs in any of the slots that are not reserved for Switch Control Boards (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.
