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.

EX9200-32XS 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.
