Line Card Ports - Juniper EX8208 Hardware Manual

Line card status LEDs—Two status LEDs labeled ON and ST that indicate the online and status for the
line card. See "Line Card LEDs in an EX8200 Switch" on page
Network port LEDs—Two LEDs per network port that indicate the link/activity and status of each port.
See Network Port LEDs in an EX8200 Switch.

Line Card Ports

Table 44 on page 96 shows the port number, port type, and port throughput on an EX8200-2XS-40T line
card.
Table 44: Ports on the EX8200-2XS-40T Line Card
Port Number Port Type
0 through 39 Oversubscribed, RJ-45
40 through 43 SFP
44 and 45 SFP+
The ports are divided into two port groups:
The RJ-45 ports 0–19 and SFP ports 40 and 41 form one port group.
The RJ-45 ports 20–39 and SFP ports 42 and 43 form another port group.
The ports in each group share 10 gigabits of bandwidth. The SFP ports operate at 1 gigabit bandwidth.
Thus, you can transmit up to 8 gigabits of traffic through a port group when the SFP ports are active and
up to 10 gigabits when the SFP ports are not active, 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.

Line rate Can be used as an uplink of 1-Gigabit Ethernet fiber
links in a link aggregation group (LAG).
