Control Board (QFX10000-RE)


Line Cards

The QFX10008 features eight horizontal line card slots and supports line rate for each line card. The line cards combine a Packet Forwarding Engine (PFE) and Ethernet interfaces enclosed in a single assembly. The QFX10008 line-card architecture is based on number of identical, independent PFE slices each with 500 Gbps full-duplex throughput. Line cards are FRUs that can be installed in the line-card slots labeled 0 through 7 (top to bottom) on the front of the switch chassis. All line cards are hot-removable and hot-insertable.

The QFX10008 supports the following line cards:

  • QFX10000-36Q–provides 36 ports of 40-gigabit QSFP+. Twelve ports are designed to be 100-Gigabit capable using QSFP28. Each of the 40-Gigabit QSFP+ can be configured as either a native 40-Gigabit port or four 10-Gigabit ports using a breakout cable. With breakout cables, the line card supports a maximum of 144 logical 10-Gigabit Ethernet ports.

  • QFX10000-30C–provides 30 ports of either 100-gigabit or 40-gigabit QSFP28. The ports autodetect the type of transceiver installed and set the configuration to the appropriate speed. Each of the 40-gigabit ports can be configured as either a native 40-gigabit port or four 10-gigabit ports using a breakout cable. With breakout cables, the line card supports a maximum of 96 logical 10-Gigabit Ethernet ports.

  • QFX10000-30C-M–provides 30 ports of either 100-gigabit or 40-gigabit QSFP28 that support MACsec security features.

  • QFX10000-60S-6Q–provides 60 SFP+ ports that can be configured for either 1-gigabit or 10-gigabit speeds. The card also provides six flexible configuration ports for 100-gigabit and 40-gigabit speeds. Of the six flexible configuration ports, two ports have QSFP28 sockets that support either 100-gigabit or 40-gigabit speeds. The remaining four ports have QSFP+ sockets that can be configured as either a native 40-gigabit port or four 10-gigabit ports using a breakout cable. With breakout cables, the line card supports a maximum of 84 logical 10-Gigabit Ethernet ports.

  • QFX10K-12C-DWDM-provides 6 coherent dense wavelength-division multiplexing (DWDM) ports with built-in optics. The card supports MACsec security features and provides a flexible rate modulation at 100 Gbps, 150 Gbps, and 200 Gbps speeds.

See Figure 5 for an example of a QFX10008 line card.

Switch Fabric

Five Switch Interface Boards (SIBs) provide the necessary switching functionality to a base configuration QFX10008. A sixth SIB is available in the redundant configuration to provide n+1 redundancy. SIBs are installed between the line cards and the fan trays inside of the chassis (see Figure 6). Each QFX10008 SIB has eight connectors that match to a line-card slot, eliminating the need for a backplane. When all six SIBs are installed, the QFX10008 has a net switching capacity of 42 Tbps. See QFX10008 Switch Interface Board.

Cooling System

The cooling system in a QFX10008 consists of two hot-removable and hot-insertable field-replaceable fan trays (see Figure 7) and two fan tray controllers (see Figure 8). The fan trays install vertically on the rear of the chassis and provides front-to-back chassis cooling. See QFX10008 Cooling System.

Power Supplies

The QFX10008 switches support AC, DC, high voltage alternating current (HVAC) and high voltage direct current (HVDC) by offering the following power supplies:

  • QFX10000-PWR-AC

  • JNP10K-PWR-AC2

  • QFX10000-PWR-DC

  • JNP10K-PWR-DC2

All of the power supplies are fully redundant, load-sharing, and hot-removable and hot-insertable field-replaceable units (FRUs). Each QFX10008 base configuration has three QFX10000-PWR-AC or QFX10000-PWR-DC power supplies; redundant configurations hold the maximum of six QFX10000-PWR-AC or QFX10000-PWR-DC power supplies. There are also high-voltage alternating current (HVAC), DC and high-voltage direct current (HVDC) base and redundant configurations. See QFX10008 Configurations and Upgrade Options. Each power supply has an internal fan for cooling. You can install the power supplies in any slot. See Table 1 and Figure 9 through Figure 12. See QFX10000 Status Panel. Table 1 provides the specifications for these different power supplies.

QFX10000 Component Redundancy

The QFX10000 is designed so that no single point of failure can cause the entire system to fail. The following major hardware components in the redundant configuration provide redundancy:

  • Routing and Control Board (RCB)—The RCB consolidates the Routing Engine function with control plane function in a single unit. The QFX10000 can have one or two RCBs. When two RCBs are installed, one functions as the primary and the other functions as the backup. If the primary RCB (or either of its components) fails, the backup can take over as the primary. See QFX10000 Routing and Control Board Description.

  • Switch Interface Boards (SIBs)—The QFX10000 has six SIB slots. Five SIBs are required for base operation and the sixth SIB provides n+1 redundancy. All six SIBs are active and can sustain full throughput rate. The fabric plane can tolerate one SIB failure without any loss of performance. See the QFX10008 Switch Interface Board Description and QFX10016 Switch Interface Board Description.

  • Power supplies—The QFX10000 requires three power supplies for minimum operation (two RCBs, two fan trays, six SIBs and no line cards). With additional power supplies, it provides n+1 redundancy for the system. AC, DC, HVAC, and HVDC systems tolerate a single power supply to fail without system interruption. If one power supply fails in a fully redundant system, the other power supplies can provide full power to the QFX10000 indefinitely.

    The QFX10000 also supports source redundancy. Two sets of lugs are provided for the QFX10000-PWR-AC cables, four sets of lugs are provided for the JNP10K-PWR-DC2 cables, and two AC power cords are provided for each JNP10K-PWR-AC2 power supply.

  • Cooling system—The fan trays have redundant fans, which are controlled by the fan tray controller. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the switch indefinitely. See QFX10008 Cooling System and Airflow and QFX10016 Cooling System and Airflow .
