System Software on page 10 QFX5100 Hardware QFX5100 line of switches offer two compact 1 U models and a 2 U model that provide wire-speed packet performance, very low latency, and rich set of Layer 2 and Layer 3 features. In addition to a high-throughput Packet Forwarding Engine, the performance of the control plane running on all the QFX5100 switches is enhanced by the 1.5 Ghz...
Page 24: Figure 1: Qfx5100-48S Port Panel
The QFX5100-48S provides full duplex throughput of 1.44 Tbps. The QFX5100-48S has a 1 U form factor and comes standard with redundant fans and redundant power supplies. The switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies.
Page 25: Figure 2: Qfx5100-48T Port Panel
24 high-density QSFP+ ports. Each QSFP+ port can operate as a native 40 Gbps port or as 4 independent 10 Gbps ports. The QFX5100-24Q switch has a 1 U form factor and comes standard with redundant fans and redundant power supplies.

However, when an EX4600-EM-8F is inserted instead of the default QFX-EM-4Q, the new configuration causes the interfaces to temporarily go down. Likewise, when an EX4600-EM-8F is running on the QFX5100-24Q and it is swapped with a QFX-EM-4Q, the interfaces temporarily go down, which can cause a short disruption in traffic.

Page 32: Understanding Hardware Redundancy Of Qfx5100 Device Components And Functionality
Functionality The following hardware components provide redundancy on a QFX5100 switch: Power supplies—The QFX5100 switch has one or two power supplies. Each power supply provides power to all components in the switch. If two power supplies are installed, the two power supplies provide full power redundancy to the device. If one power supply fails or is removed, the second power supply balances the electrical load without interruption.
Page 33 Cooling system—The 1 U models of QFX5100 line of switches have five fan modules; the 2 U QFX5100-96S has three fan modules. If a fan module fails and is unable to keep the QFX5100 switch within the desired temperature thresholds, chassis alarms occur and the QFX5100 switch can shut down.

Page 37: Switch Ports
Expansion Module adds the switch uplink capacity by 2 for a total of 8 uplinks. To connect a QFX5100-24Q switch as a Node device in a QFabric system, you need: Four QSFP+ uplink ports on each QFX5100-24Q Node device to connect to the data plane network through the QFX3008-I or QFX5100-24Q Interconnect devices.
Page 38: Channelizing Interfaces (Non-Qfabric)
4 QFX5100 devices can be configured as spines. To connect a QFX5100-24Q device as a member in a QFX Virtual Chassis, you need to cable a pair of ports to link each member in the Virtual Chassis into a ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP) connection to each directly connected member.
Page 39: Port Leds
Chapter 2: Chassis Components and Descriptions To connect a QFX5100-24Q device as a spine or leaf device in a VCF, you need to cable a set of ports as VCP connections that link each spine device and leaf device. All spine devices have at least one direct VCP connection to each leaf device in the VCF.

Page 59: Expansion Modules For Qfx5100 Devices
Expansion Modules for QFX5100 Devices The QFX5100-24Q and QFX5100-24Q-AA devices have two bays on the port panel for optional expansion modules. These expansion modules can be hot-inserted or hot-removed. Expansion modules and transceivers are not shipped with the switch and must be ordered separately.
Page 60: Ex4600-Em-8F
When the expansion module is inserted into the expansion bay, the chassis detects the additional ports, recognizes them as 10GbE ports, and lights the Status LED. The QFX5100-24Q device is configured for the QFX-EM-4Q by default, but any combination of the two modules is supported. Expansion modules can be hot-inserted or hot-removed.
Page 61: Qfx-Em-4Q
QFX-EM-4Q The QFX-EM-4Q, provides 4 additional 40-Gigabit Ethernet QSFP+ ports to one of the bays in the QFX5100-24Q or QFX5100-24Q-AA. Port 0 and port 2 can be used for port channelization by configuring the system mode for 104 port mode.

When chromatic dispersion is at the maximum allowed, its effect can be considered as a power penalty in the power budget. The optical power budget must allow for the sum of component attenuation, power penalties (including those from dispersion), and a safety margin for unexpected losses.
