I/O Cards

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 5 on page 9).
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).
The services gateway has a total of 8 slots. You can install IOCs in any of the slots
numbered
The slots at the bottom of the card cage numbered
IOCs install horizontally in the front of the device (see Figure 6 on page 9). You can
install any combination of IOC types in the device.
If a slot is not occupied by a card, a blank panel must be installed to shield the empty
slot and to allow cooling air to circulate properly through the services gateway.
Figure 5 on page 9 shows the IOCs supported on the SRX 5600 services gateways.
