48-Port Sfp Line Card In An Ex8200 Switch - Juniper EX8208 Hardware Manual

The ports are divided into two port groups:
The ports 0 through 23 form one port group.
The ports 24 through 47 form another port group.
The ports in each group share 10 gigabits of bandwidth. You can transmit up to 10 gigabits of traffic
through a port group without packet drop. The oversubscription ratios of different port groups can differ
from one another; the ratios depend on the amount of traffic being transmitted through a port group.
For more information about using these ports:
To understand how traffic is handled by oversubscribed ports, see Understanding CoS Queues on EX8200

The line cards in EX8200 switches combine a Packet Forwarding Engine and Ethernet interfaces on a single
assembly. They are field-replaceable units (FRUs) that can be installed in the line card slots on the front
of the switch chassis. The line cards are hot-insertable and hot-removable: You can remove and replace
them without powering off the switch or disrupting switch functions (see
