EX9200-12QS 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 2 shows the model number, description of the line card model, and the Junos OS release in which the line card was first supported.

See Figure 2.

You can use the show version command to see the version of Junos OS for EX Series switches loaded on the switch.

Line Card Components

• Twelve rate-selectable Gigabit Ethernet ports. All ports can operate at 10-Gbps and 40-Gbps speeds. The ports are configured to operate at 10-Gbps speed by default. The ports labeled 0/2, 0/5, 1/2, and 1/5 (see Figure 2) can operate at 100-Gbps speed also. You can configure the port speed by using the following command:

  user@host# set chassis fpc fpc-slot-number pic pic-slot-number pic-mode pic-speed number-of-ports number
  • You can configure a port to operate at 10-Gbps speed. The ports support QSFP+-4X10G-SR and QSFP+-4X10G-LR transceivers. If you configure the ports to operate at 10-Gbps speed, each port operates as four 10-Gbps interfaces.
  • You can configure a port to operate at 40-Gbps speed and install a 40-gigabit QSFP+ transceiver in the port. The ports support QSFP+-40GE-SR4 and JNP-QSFP+-40G-LR4 transceivers.
  • You can configure the ports labeled 0/2, 0/5, 1/2, and 1/5 (see Figure 2) to operate at 100-Gbps speed and install 100-gigabit QSFP+ transceivers in these ports. These ports support QSFP-100GBASE-SR4 and QSFP-100GBASE-LR4 transceivers.
• Twelve dust covers for the ports
• Line card LED—An LED labeled OK/FAIL, which indicates the status of the line card. See Line Card LED in an EX9200 Switch.
• Network port LED—Four LEDs for each network port, the Link/Activity LED, which indicates the link status and activity on the port. See Network Port LEDs on Line Cards in an EX9200 Switch.

  There are four LEDs labeled 0, 1, 2, and 3 for each port (see Figure 2). If a port is configured to operate at 10-Gbps speed, four 10-Gbps interfaces are created and the LEDs labeled 0, 1, 2, and 3 for that port becomes operational. Each of these LEDs indicates the link/activity on each four interfaces on the corresponding port. If a port is configured to operate at 40-Gbps speed, the LED labeled 0 for that port becomes operational. If the ports labeled 0/2, 0/5, 1/2, and 1/5 are configured to operate at 100-Gbps speed, the LED labeled 3 for each of these ports becomes operational.

The ports are divided into two port groups. The six ports labeled 0/0 through 0/5 form one port group, PIC 0. The six ports labeled 1/0 through 1/5 form the other port group, PIC 1. The ports in each group share 240 gigabits of bandwidth. Thus, you can transmit up to 240 gigabits of traffic through a port group without packet drop.
