Juniper SRX5K-MPC3-40G10G

The cards described in this guide let you upgrade and customize your SRX5400, SRX5600, or SRX5800 Firewall to suit the needs of your network. The following types of cards are available for the SRX5400, SRX5600, and SRX5800 Firewalls:

• I/O cards (IOCs) provide additional physical network connections to the firewall. Their primary function is to deliver data packets arriving on the physical ports to the Services Processing Cards (SPCs) and to forward data packets out the physical ports after services processing.

• Flex IOCs have two slots for port modules that add additional physical network connections to the firewall. Like IOCs, their primary function is to deliver data packets arriving on the physical ports to the SPCs and to forward data packets out the physical ports after services processing.

• 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 interfaces 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 firewall. 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.

• Services Processing Cards (SPCs) provide the processing power to run integrated services such as firewall, IPsec and IDP. All traffic traversing the firewall 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 Firewall, this guide also addresses the following modules that fit into certain SRX5400, SRX5600, and SRX5800 Firewall 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 firewall.

• Modular Interface Cards (MICs) fit into slots in MPCs and add additional physical network interface ports to the firewall. 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.
