24-Port 10-Gigabit Ethernet, 40-Gigabit Ethernet PIC with QSFP+ (PTX Series)

Software Release

• PTX3000: Junos OS Release 15.1F6, Junos OS Release 16.1R2 and later, Junos OS Release 17.1R1 and later

• PTX5000: Junos OS Release 15.1F3 and later, Junos OS Release 16.1R2 and later, Junos OS Release 17.1R1 and later

For information about which FPCs support these PICs, see PTX Series PIC/FPC Compatibility.

Hardware Features

• Twenty-four ports (0 through 23) configurable as 10-Gigabit Ethernet ports or 40-Gigabit Ethernet ports. If the port speed is not configured, the default port speed on all ports on the PIC is 10 Gbps.

  Note:

  You can use the following command to change the mode:

  [edit chassis]

  user@host# set fpc slot-number pic pic-number port port-number speed (10G | 40G)

  The interface speeds are configured by port group. There are eight port groups on the 24-port PIC—each port group consists of three ports. The port groups are:

  • 0 through 2

  • 3 through 5

  • 6 through 11

  • 12 through 14

  • 15 through 17

  • 18 through 20

  • 21 through 23

  When you configure the first port in a group the remaining ports in the group are configured with the same port speed. For example, if you configure the port-speed of port 0 to be 10G, then ports 0, 1, and 2 operate at 10 Gbps. If you later change the port-speed configuration of port 0 to 40G, then ports 0, 1, and 2 operate at 40 Gbps. Only the first port in each port group can be configured.

• Model number: P3-24-U-QSFP28

LEDs

The STATUS LED is located on the left side of the PIC, the opposite end of the ONLINE/OFFLINE button. There are 24 port LEDs grouped in pairs below each set of ports. The LED located below the port pairs indicates the status of the port. Table 2 describes the functions of these LEDs.
