EX9200-40XS 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.

Line Card Components

The EX9200-40XS line card has:

  • 40 10-Gigabit Ethernet MACsec-capable ports, each of which can house SFP+ transceivers. These ports support 10GBASE-SR, 10GBASE-LRM, and 10GBASE-LR transceivers.
  • 40 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—One LED on 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.

The ports are divided into two port groups of 20 ports each. The 10-Gigabit Ethernet ports labeled 0/0 through 0/19 form one port group. The 10-Gigabit Ethernet ports labeled 1/0 through 1/19 form the other port group. The ports in each group share 200 gigabits of bandwidth. Thus, you can transmit up to 200 gigabits of traffic through each port group, without packet drop.
