EX9200-15C Line Card


The line cards in EX9200 switches combine a Packet Forwarding Engine and Ethernet interfaces in a single assembly. Line cards are field-replaceable units (FRUs) that you can install in the line card slots on the front of the switch chassis. Line cards are hot-insertable and hot-removable: You can remove and replace them without powering off the switch or disrupting switch functions.

Line Card Models

Table 1 shows the model number, description of the line card model, and the Junos OS release in which the line card was first supported.

Table 1: EX9200-15C Line Card



Junos OS Release Required

Name In the CLI


  • Fixed-configuation line card with 15 rate-selectable ports. All ports can operate at 10-Gbps, 25-Gbps, 40-Gbps, or 100-Gbps speeds. The ports are configured to operate at 100-Gbps speed by default.

  • Line-rate throughput of up to 1.5 Tbps when installed with an enhanced midplane.

    Note: In the CLI, when you run the show chassis hardware command, the midplane description will say <platform>-BP3 for an enhanced midplane. The EX9214 only uses enhanced midplanes.

  • Line-rate throughput of up to 800 Gbps when installed with a standard midplane.

    Note: In the CLI, when you run the show chassis hardware command, the midplane description will say <platform>-BP for a standard midplane.

  • Supports maximum transmission units (MTUs) from 256 bytes through 16,000 bytes for transit traffic, and from 256 bytes through 9500 bytes for host-bound packets.

20.3R1 or later


  • For the EX9200-15C line card to be operational, you must install the EX9200-SF3 Switch Fabric module (SF module) in the switch. See EX9200-SF3 Module in an EX9200 Switch.

  • To achieve maximum line-rate performance, the line card’s fabric redundancy mode must be configured in increased bandwidth mode.

  • To achieve maximum performance, the following number of EX9200-SF3 SF modules must be installed in the system:

    • EX9214—Three EX9200-SF3 SF modules

    • EX9204 and EX9208—Two EX9200-SF3 SF modules

Line Card Components

The EX9200-15C line card has:

  • Fifteen network ports that can be configured for 10-Gbps, 25-Gbps, 40-Gbps, or 100-Gbps (breakout cables are used for 10-Gbps and 25-Gbps speeds).

  • The Switch Processor Mezzanine Board (SPMB) consists of a 1.6-GHz Intel Broadwell 8-core CPU, 100-GB SATA SSD, and two 16-GB ECC DDR4 DRAM modules.

  • Three Packet Forwarding Engines, each providing a maximum bandwidth of 500 Gbps.

  • Juniper Penta silicon for increased scaling for bandwidth, subscribers, and services.


On EX9214 switches, the EX9200-15C is not supported in the line-card slots numbered 0, 1, and 11.

EX9200-15C Power Requirements

The power numbers are measured using the following configuration:

  • IPv4 forwarding with 200-bytes packet size

  • Line-rate traffic on all ports for 1.5-Tbps aggregate bandwidth

  • All 15 ports are configured for 100GbE, with QSFP28 LR4 transceivers installed on all ports

At different temperatures:

  • 104° F (40° C): 785 W

  • 77° F (25° C): 720 W

EX9200-15C LEDs

OK/FAIL LED, one bicolor:

  • Green—MPC is functioning normally.

  • Red—MPC has failed.

Port LED:

  • Off—Port link is down with loss of signal.

  • Green—Port link is up with no alarms or failures.

  • Amber—Port link is down with alarms. Or the port has been administratively disabled through the CLI.

  • Red—A transceiver on the port is experiencing a fault.

Lane LED:

There are four Lane LEDs, which are shared by the network ports. The Lane LEDs work with the Junos OS software to determine which port the Lane LEDs are displaying the status for.

The Lane LEDs are used for the following configurations:

  • When a network port is configured for 4 x 10GbE channelized interfaces with a breakout cable.

  • When a network port is configured for 4 x 25GbE channelized interfaces with a breakout cable.

Cables and Connectors

You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device.

The list of supported transceivers for the EX Series is located at EX Series Supported Transceivers.
