15-Port 10-Gigabit, 40-Gigabit Ethernet, 100-Gigabit Ethernet PIC with QSFP28 (PTX Series)

Software Release

• PTX5000: Junos OS Release 15.1F5 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

• Fifteen ports (0 through 14) configurable as 10-Gigabit Ethernet ports, 40-Gigabit Ethernet ports, or 100-Gigabit Ethernet ports. If the port speed is not configured, the port speed on all ports on the interface module will be 100 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 | 100G)

• Model number: P3-15-U-QSFP28

• Name in the CLI: 15x100/15x40/60x10G QSFP+

• Independent per-port configuration of:

  • LAN-PHY for ports configured in 10-Gigabit Ethernet mode—Can be configured only on port numbers 0, 5, or, 10. The subsequent four ports are also configured in 10-Gigabit Ethernet mode.

  • LAN-PHY for ports configured in 40-Gigabit Ethernet mode—Can be configured only on port numbers 0, 5, or, 10. The subsequent four ports are also configured in 40-Gigabit Ethernet mode.

  • LAN-PHY for ports configured in 100-Gigabit Ethernet mode—Can be configured only on port numbers 0, 5, or, 10. The subsequent four ports are also configured in 100-Gigabit Ethernet mode.

  Note:

  To install the P3-15-U-QSFP28 PIC, you must have a third-generation FPC installed on your system.

  Following is the available port configuration for each FPC:

  • FPC3-PTX-U2-L and FPC3-PTX-U2-R—10 ports configurable as 10-Gigabit Ethernet ports (using a 4x breakout cable), 40-Gigabit Ethernet ports, or 100-Gigabit Ethernet ports. Only ports 0 through 9 can be used. Ports 10 through 14 cannot be used.

  • FPC3-PTX-U3-L and FPC3-PTX-U3-R—15 ports configurable as 10-Gigabit Ethernet ports (using a 4x breakout cable), 40-Gigabit Ethernet ports, or 100-Gigabit Ethernet ports.

• Power requirements:

  • 10-Gigabit Ethernet LAN mode (with QSFP+ transceivers on all ports)—9.1 A @ –12 V (110 W)

  • 40-Gigabit Ethernet LAN mode (with QSFP+ on all ports)—9.1 A @ –12 V (110 W)

  • 100-Gigabit Ethernet LAN mode (with QSFP28 on all ports)—10.8 A @ –12 V (130 W)

• High-performance throughput:

  • 10-Gigabit Ethernet LAN mode at 10.3 Gbps

  • 40-Gigabit Ethernet LAN mode at 41.2 Gbps (10.3 Gbps per lane)

  • 100-Gigabit Ethernet LAN mode at 103.1 Gbps (25.8 Gbps per lane)

• Configurable modes:

  • LAN-PHY—10-Gigabit Ethernet, 40-Gigabit Ethernet, or 100-Gigabit Ethernet

• Full-duplex mode

• Large maximum transmission units (MTUs): up to 9500 bytes

Cables and Connectors

LEDs

The STATUS LED is located on the front of the PIC next to the ONLINE/OFFLINE button. There are 15 port LEDs labeled 0 through 14. The LED located next to the port number indicates the link activity of the port. Table 2describes the functions of these LEDs.
