SRX5800 Services Gateway Interface Card Description

Copyright © 2015, Juniper Networks, Inc.
Interface cards are cards that support physical interfaces that you use to connect the
services gateway to your data network. Three different types of interface cards are
available:
I/O Cards (IOCs) have fixed interface ports on the front panel of the card.
Flex I/O Cards (Flex IOCs) have slots on the front panel that accept smaller cards
called port modules. Each port module has two or more physical interfaces on it. 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.
Modular Port Concentrators (MPCs) have slots on the front panel that accept smaller
cards called Modular Interface Cards (MICs). Each MIC has one or more physical
interface on it. An MPC with MICs installed functions in the same way as a regular I/O
card (IOC), but allows greater flexibility in adding different types of Ethernet ports to
your services gateway. MPCs and MICs are similar in form and function to Flex IOCs
and port modules. However, the two use different form-factors, so you cannot install
port modules in an MPC, nor can you install MICs in a Flex IOC.
For all interface card types, the card assembly combines packet forwarding and Ethernet
interfaces on a single board. The interface cards interface with the power supplies and
Switch Control Boards (SCBs).
You can install interface cards in any of the slots that are not reserved for 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.
Figure 1 on page 8 shows typical IOCs supported on the services gateway.
