SRX5800 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 1 shows a Flex IOC with two typical port modules installed.
Figure 1: Flex IOC with Port Modules
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 1 describes the different port modules available.
Table 1: Port Module Types
Port Module Name | Number of Ports | Port Type | Maximum Throughput | Oversubscription Ratio | Maximum Configurable MTU |
---|---|---|---|---|---|
4x10GE-XFP | 4 | XFP 10 Gbps | 10 Gbps | 4:1 | 9192 Bytes |
16x1GE-TX | 16 | RJ-45 1 Gbps | 10 Gbps | 1.6:1 | 9192 Bytes |
16x1GE-SFP | 16 | SFP 1 Gbps | 10 Gbps | 1.6:1 | 9192 Bytes |
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 2.

Note: We strongly recommend the use of Juniper Networks SFP and XFP transceivers. We cannot guarantee correct operation if other transceivers are used. The transceiver type can be different in each port, as long as a supported part number is used. |
