Two dust covers for the two 100-Gigabit Ethernet ports and eight dust covers for the
eight 10-Gigabit Ethernet 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” on page 71 .
•
LEDs for the ports—One LED on each 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” on page 33 .
The ports are divided into two port groups. The four 10-Gigabit Ethernet ports labeled
0/0
through
0/3
and the 100-Gigabit Ethernet port labeled
1/0
form one port group. The
four 10-Gigabit Ethernet ports labeled
2/0
through
2/3
and the 100-Gigabit Ethernet port
labeled
3/0
form the other port group. The ports in each group share 130 gigabits of
bandwidth. Thus, you can transmit up to 130 gigabits of traffic through a port group,
without packet drop.

EX9200-4QS Line Card
The line cards in EX9200 switches combine a Packet Forwarding Engine and Ethernet
interfaces on a single assembly. They 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.
