I/O Card SRX5K-40GE-SFP Specicaons
The SRX5K-40GE-SFP I/O card (IOC) is opmized for Ethernet density and supports 40 Gigabit
Ethernet ports (see Figure 7 on page 26). 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 rewall. 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 rewall.
