I/O Card SRX5K-40GE-SFP Specifications
The SRX5K-40GE-SFP I/O card (IOC) is optimized for Ethernet density and supports 40 Gigabit Ethernet
ports (see Figure 7 on page 24). 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.
