Network Processing Cards

Network Processing Cards (NPCs) are common form-factor module (CFM) cards that receive inbound traffic from the I/O cards (IOCs) and direct it to the appropriate Services Processing Card (SPC) for processing. Once services processing is complete, the NPC receives outbound traffic from the SPC(s) and directs it back to the appropriate IOC. Additionally, the NPC performs the following functions:

Buffers incoming traffic and queues outgoing traffic.
Performs advanced traffic management, including denial of service/distributed denial of service (DoS/DDoS) protective measures. For example, it can drop traffic to or from a particular IP address, protecting the device from Internet Control Message Protocol (ICMP), UDP, and TCP SYN flooding, and buffering bursty traffic to protect the SPC.

If a CFM 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 device.
The ONLINE button on NPC does not perform any function and currently it is not supported.

Figure 65 shows the NPC that can be used on SRX1400 Services Gateway.

Table 53 describes the NPC behavior indicated by the LEDs on its front panel.

Label	Color	Status	Description
SERVICE	Green	On steadily	The NPC is mapped to an IOC and is actively carrying traffic.
	Amber	On steadily	The NPC is mapped to an IOC, but there is no SPC present or reachable in the system so all traffic is dropped.
