Page 21: System Overview
System Software on page 4 QFX5200-32C Hardware The QFX5200-32C is a compact 1 U standalone switch that provides a line rate configuration packet performance, very low latency, and a rich set of Layer 3 features. The routing engine and control plane are driven by the 1.8 Ghz quad-core Intel CPU with 16 GB of memory and two 32 GB solid-state drives (SSD) for storage.
Page 22: System Software
Junos OS is installed on the redundant 32 GB solid state drives. The same Junos OS code base that runs on QFX5200 switches also runs on all Juniper Networks EX Series switches, and J Series, M Series, MX Series, and T Series routers.
Page 23: Functionality
Do not connect feed A and feed B to the same power supply input terminal. Cooling system—The QFX5200 has five fan modules. If a fan module fails and is unable to keep the QFX5200 switch within the desired temperature thresholds, chassis alarms occur and the QFX5200 switch can shut down.
Page 25: Chassis Components And Descriptions
Installing and Removing QFX5200 Hardware Components on page 99 QFX5200-32C Port Panel The port panel of the QFX5200-32C supports port configuration speeds of 100, 50, 40, 25, or 10 Gigabit Ethernet. The QFX5200-32C uses 28-Gbps quad small-form factor pluggable plus (QSFP28) sockets that are configured as 100 Gigabit Ethernet ports by default.
Page 26: Switch Ports
QSFP+ to SFP+ DACBO cables (40 Gbps breaks out to 10 Gbps) Channelizing Interfaces For downstream traffic, the QFX5200-32C has 32 physical or 128 logical ports (32 x 4) that can be used for port channelization. The 100 Gigabit Ethernet ports can be channelized using breakout cables either to 2 independent downstream 50 Gigabit Ethernet or to 4 independent 25 Gigabit Ethernet ports.

Page 65: Signal Loss In Multimode And Single-Mode Fiber-Optic Cables
An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications. In addition, the total dispersion must be within the limits specified for the type of link in the Telcordia Technologies Copyright © 2017, Juniper Networks, Inc.
