Modular Port Concentrator (SRX5K-MPC) Specifications

The SRX5K-MPC (see Figure 10) is an interface card with two slots that accept MICs. These MICs add Ethernet ports to your services gateway. An MPC with MICs installed functions in the same way as a regular IOC but allows you to add 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.

You must install at least one interface card in the services gateway. The interface card can be of any of the available IOC, Flex IOC, or MPC types. You can add just one MIC; or you can add two MICs of the same or different types.

You can install MPCs in any of the slots that are not reserved for Switch Control Boards (SCBs).

If a slot in the SRX5400, SRX5600, or SRX5800 Services Gateway card cage 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. If a slot in an MPC is not occupied by a MIC, you must install a blank panel in the empty MIC slot to shield it and to allow cooling air to circulate properly through the MPC.

SRX5K-MPC

Note: When installing an SRX5K-MPC in an SRX5600 or SRX5800 Services Gateway:

  • If the session-distribution-mode has not been explicitly configured using the CLI command:

    user@host set security forwarding-process application-services session-distribution-mode

    The SRX5K-MPC defaults to hash-based mode automatically even if existing SRX5K-MPC or non-MPCs are installed. You cannot set the session-distribution-mode to normal.

  • If the session-distribution-mode has been explicitly configured to normal, and the MIC is installed in the device, then the SRX5K-MPC will remain offline, and the services gateway generates a major alarm and logs the event for troubleshooting. You must explicitly configure the session-distribution-mode using the CLI command:

    user@host set security forwarding-process application-services session-distribution-mode hash-based

When installing an SRX5K-MPC in an SRX5400 Services Gateway, the session-distribution-mode will only function when hash-based mode is configured or set as the default. The normal mode is not supported.

A 9% drop is observed for PPS (throughput) when moving from session mode to hash mode (for SRX5K-MPC or non-MPCs), whereas no drop in performance is observed on CPS (connection per second) and session capacity numbers.

For more information about the CLI command, see the Junos OS documentation at www.juniper.net/techpubs/.

Description

  • MPC with slots for two MICs
  • Maximum throughput:

    75 Gbps per slot from Junos OS Release 12.1X46-D10 and later

    120 Gbps per slot from Junos OS Release 12.1x47-D15 and later

Software release

Junos OS Release 12.1x46-D10

Cables and connectors

Slots for two MICs

Controls

One ejector knob each for MIC slots 0 and 1. Pull the ejector knob to unseat and partially eject the adjacent MIC.

Supported slots

  • SRX5400–Any slot except bottom slot 0
  • SRX5600–Any slot except bottom slots 0 or 1
  • SRX5800–Any slot except center slots 0 or 1

Power requirement

Maximum of 570 W for the MPC with two MICs, including applicable transceivers.

Note:

  • To install and use SRX5K-MPCs 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 gateways. All models of SRX5400 Services Gateways already include high-capacity supplies. 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-MPCs.
  • On SRX5400 and SRX5600 Services Gateways with AC power supplies, we recommend that you use high-line (220 V) input power to ensure that the devices have adequate power to support SRX5K-MPCs.

Weight

Approximately 10 lb (4.5 kg) without MICs

LEDs

OK/FAIL LED, one bicolor:

  • Green–The MPC is operating normally.
  • Blinking green–The MPC is transitioning to online or offline.
  • Red–The MPC has failed and is not operating normally.
  • Off–The MPC is powered down.

Serial number location

The serial number label is yellow and is located on the opposite side of the card.
