Srx5600 Services Gateway Card Terminology - Juniper SRX5600 Hardware Manual

Services Processing Cards (SPCs) provide the processing power to run integrated services such as firewall,
IPsec and IDP. All traffic traversing the services gateway is passed to an SPC to have services processing
applied to it.
Switch Control Boards (SCBs) power on and power off IOCs and SPCs; control clocking and system
resets; and control booting, monitor, and system functions. Each SCB has a slot in the front panel for a
Routing Engine.
Although the following modules are not cards in the sense of having a form-factor that fits the card cage
of the SRX5400, SRX5600, and SRX5800 Services Gateway, this guide also addresses the following modules
that fit into certain SRX5400, SRX5600, and SRX5800 Services Gateway cards:
Routing Engines fit into slots in SCBs and maintain the routing tables, manage the routing protocols used
on the device, control the device interfaces and some chassis components, and provide the interface
for system management and user access to the device.
Port modules fit into slots in Flex IOCs and add additional physical network interface ports to the services
gateway.
Modular Interface Cards (MICs) fit into slots in MPCs and add additional physical network interface ports
to the 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.

SRX5600 Services Gateway Card Terminology

Regardless of orientation, this information uses the same terms for all four edges of the card (see
Figure 40 on page 94):
Faceplate—Edge of the card that has connectors to which you connect cables or sockets in which you
insert SFP or XFP transceivers.
Connector edge—Edge opposite the faceplate; this edge has the connectors that attach to the midplane.
Top edge—Edge at the top of the card when it is vertical.
Bottom edge—Edge at the bottom of the card when it is vertical.
NOTE: This terminology applies to SPCs, IOCs, MPCs, and SCBs in addition to Routing Engines
and port modules.
