Services Processing Card SRX5K-SPC-4-15-320 Specifications

The SRX5K-SPC-4-15-320 Services Processing Card (SPC) contains four Services Processing Units (SPUs), which provide the processing power to run integrated services such as firewall, IPsec, and IDP (see Figure 4). All traffic traversing the services gateway is passed to an SPU to have services processing applied to it. Traffic is intelligently distributed by I/O cards (IOCs) to SPUs for services processing.

The services gateway must have at least one SPC installed. You can install additional SPCs to increase services processing capacity.

You can install SPCs in any of the slots that are not reserved for Switch Control Boards (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 device.

If your services gateway contains a mix of SRX5K-SPC-4-15-320 SPCs and earlier SRX5K-SPC-2-10-40 SPCs, an SRX5K-SPC-4-15-320 SPC must occupy the lowest-numbered slot of any SPC in the chassis. This configuration ensures that the center point (CP) function is performed by the faster and higher-performance SPC type.

Each SPC consists of the following components:

  • SPC cover, which functions as a ground plane and a stiffener.
  • Two small form-factor pluggable (SFP) chassis cluster control ports for connecting multiple devices into a redundant chassis cluster. See Junos OS Security Configuration Guide for more information about connecting and configuring redundant chassis clusters.

    Caution: If you face a problem running a Juniper Networks device that uses a third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.

  • Fabric interfaces.
  • Two Gigabit Ethernet interfaces that allow control information, route information, and statistics to be sent between the Routing Engine and the CPU on the SPCs.
  • Two interfaces from the SCBs that enable the boards to be powered on and controlled.
  • Physical SPC connectors.
  • Midplane connectors and power circuitry.
  • Processor subsystem, which includes a 1.2-GHz CPU, system controller, and 1 GB of SDRAM.
  • LEDs on the faceplate that indicate the SPC and SPU status.

Software release

  • Junos OS Release 12.1X44-D10 and later

Cables and connectors

CHASSIS CLUSTER CONTROL 0 and CHASSIS CLUSTER CONTROL 1–SFP ports for control links in chassis cluster configurations.

Supported SFP transceivers:

1000BASE-LH (model numbers SRX-SFP-1GE-LH, SRX-SFP-1GE-LH-ET)

1000BASE-LX (model numbers SRX-SFP-1GE-LX, SRX-SFP-1GE-LX-ET)

1000BASE-SX (model numbers SRX-SFP-1GE-SX, SRX-SFP-1GE-SX-ET)



Supported Slots

  • SRX5400–Any slot, except the bottom slot 0 which is reserved for SCB/RE.
  • SRX5600–Any slot, except the bottom slots 0 or 1 which are reserved for SCB/RE.
  • SRX5800–Any slot, except the slots 0 or 1 which are reserved for SCB/RE.

Power Requirement

450 W typical, 585 W maximum


  • In the SRX5600 and SRX5800 Services Gateways, you must have high-capacity power supplies (either AC or DC) and high-capacity fan trays installed in the services gateway in order to install and use SRX5K-SPC-4-15-320 SPCs. If you do not have high-capacity power supplies and fan trays installed, the services gateway will log an alarm condition when it recognizes the SRX5K-SPC-4-15-320 SPCs.
  • On SRX5600 Services Gateways with AC power supplies, we recommend that you use high-line (220v) input power to ensure the device has adequate power to support SRX5K-SPC-4-15-320 SPCs.

OK/FAIL LED, one bicolor:

  • Steady green–The SPC is operating normally.
  • Red–The SPC has failed and is not operating normally.
  • Off–The SPC is powered down.

STATUS LED, one tricolor for each of the four SPUs SPU 0 through SPU 3:

  • Green–The SPU is operating normally.
  • Amber–The SPU is initializing.
  • Red–The SPU has encountered an error or a failure.
  • Off–The SPU is offline. If all four SPUs are offline, it is safe to remove the SPC from the chassis.

SERVICE LED, one bicolor for each of the four SPUs SPU 0 through SPU 3:

  • Green–Service is running on the SPU under acceptable load.
  • Amber–Service on the SPU is overloaded.
  • Off–Service is not running on the SPU.

HA LED, one tricolor:

  • Green–Clustering is operating normally. All cluster members and monitored links are available, and no error conditions are detected.
  • Red–A critical alarm is present on clustering. A cluster member is missing or unreachable, or the other node is no longer part of a cluster because it has been disabled by the dual membership and detection recovery process in reaction to a control-link or fabric-link failure.
  • Amber–All cluster members are present, but an error condition has compromised the performance and resiliency of the cluster. The reduced bandwidth could cause packets to be dropped or could result in reduced resiliency because a single point of failure might exist. The error condition might be caused by:
    • The loss of chassis cluster links which causes an interface monitoring failure.
    • An error in an SPU or NPU.
    • Failure of the spu-monitoring or cold-sync-monitoring processes.
    • A chassis cluster IP monitoring failure.
  • Off–The node is not configured for clustering or it has been disabled by the dual membership and detection recovery process in reaction to a control link or fabric link failure.


  • Green–Chassis cluster control port link is active.
  • Off–No link.


  • Green–The chassis cluster control port is enabled.
  • Off–The chassis cluster control port is disabled.
