Line Card Components
The EX9200-6QS line card has:
•
Six 40-Gigabit Ethernet ports, each of which can house QSFP+ transceivers. These
ports support 40GBASE-LR4 and 40GBASE-SR4 transceivers. Starting with Junos OS
for EX Series switches, Release 15.1 R3, these ports support the JNP-QSFP-40G-LX4
transceiver.
•
24 10-Gigabit Ethernet ports, each of which can house SFP+ transceivers. These ports
support 10GBASE-SR, 10GBASE-LR, 10GBASE-ER, and 10GBASE-ZR transceivers.
•
Line card LED—An LED labeled OK/FAIL, which indicates the status of the line card.
See “Line Card LED in an EX9200 Switch” on page 75.
•
Network port LED—One LED on each network port, the Link/ActivityLED, which indicates
the link status and activity on the port. See “Network Port LEDs on Line Cards in an
EX9200 Switch” on page 37.
The ports are divided into two port groups. The twelve 10-Gigabit Ethernet ports labeled
0/0 through 0/11 form PIC 0 and twelve 10-Gigabit Ethernet ports labeled 1/0 through
1/11 form PIC 1; PIC 0 and PIC 1 for one port group. The three 40-Gigabit Ethernet ports
labeled 2/0 through 2/2 form PIC 2 and three 40-Gigabit Ethernet ports labeled 3/0
through 3/2 form PIC 3; PIC 2 and PIC 3 form the other port group. The ports in each port
group share 240 gigabits of bandwidth. Thus, you can transmit up to 240 gigabits of
traffic through a port group, without packet drop.
Only the PICs forming one of the port groups can be active at a time. PIC 0 and PIC 1 are
activated by default. If you deactivate both PIC 0 and PIC 1, PIC 2 and PIC 3 are
automatically activated. Similarly, if you deactivate both PIC 2 and PIC 3, PIC 0 and PIC 1
are automatically activated. You can choose to deactivate one of the PICs that are
activated and keep only the other active. To deactivate an active PIC, use the power
command.

EX9200-MPC 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.
