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.

Table 28 on page 62 shows the model number, description of the line card model, and
the Junos OS release in which the line card was first supported.
Table 28: EX9200-12QS Line Card
Junos OS Release
RequiredDescriptionModel
16.1R1 or laterA line card with 12 rate-selectable ports, each
of which can house transceivers. 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 31 on page 63) can operate at
100-Gbps speed also.
EX9200-12QS
NOTE: For the EX9200-12QS line card tobe operational,you must installthe EX9200-SF2 Switch
Fabric module (SF module) in the switch. See “Switch Fabric Module in an EX9200 Switch” on
page 29 and “Installing an SF Module in an EX9200 Switch” on page 232.
Figure 31 on page 63 shows the components of an EX9200-12QS line card.
