SRX5600 Services Gateway Flex IOC and Port Module Description

Flex I/O Cards (Flex IOCs) are IOCs with two slots, which accept port modules that add Ethernet ports to your services gateway. A Flex IOC with installed port modules functions in the same way as a regular IOC, but allows greater flexibility in adding different types of Ethernet ports to your services gateway. Figure 6 shows a Flex IOC with two typical port modules installed.

Note: Your services gateway must be running Junos OS Release 9.5R1 or later in order to recognize Flex IOCs and port modules.

Each Flex IOC has a processor subsystem, which includes a 1.2-GHz CPU, a system controller, 1 GB SDRAM, and two Packet Forwarding Engines (PFEs) with a maximum throughput of 10 Gbps each.

Table 7 describes the different port modules available.

You use port modules and Flex IOCs to add different combinations of SFP, XFP, and TX ports to your services gateway to suit the specific needs of your network. The available port modules are shown in Figure 7.

Note: Juniper strongly recommends the use of Juniper SFP and SFP transceivers. Juniper cannot guarantee correct operation if non-Juniper transceivers are used. The transceiver type can be different in each port, as long as a supported part number is used.
