Statement of Volatility
Introduction
Dated: 4/17/2023
QFX5700 is a modular 5RU chassis with provision for dual-FEB cards (also referred to as PFE cards), dual-RCB cards(also
referred to as RE cards) and 8 I/O Slots. It delivers high density and cost efficient 100GE and 400GE optimized systems
and line cards based on Broadcom’s Trident 4 chipset. The primary motivation for this choice is that a single PFE system
generally provides a better economic model than the alternative multi-chip system. Broadcom is the dominant PFE
supplier for these single PFE systems and has a 12.8Tbps Trident4 PFE.
The 8 I/O slots can take a mix of the following card types.
• 16x100G QSFP28 with Macsec
• 4x400G QSFP56-DD with MacSec
• 20 x 25G/56G SFP28/SFP56 with MacSec
Purpose
The purpose of this document is to provide direction to identify volatile and non-volatile storages and remove non-volatile
(NV) storage from the Juniper Networks’ QFX5700, namely the JNP5700-CHAS, JNP5700-FAN, QFX5700-RCB, QFX5700-
FEB, QFX5K-FPC-16C, QFX5K-FPC-4CD, QFX5K-FPC-20Y.
Scope
This document only addresses the QFX5700. While other platforms offered by Juniper Networks may contain similar
hardware components, this document only applies to the QFX5700. Furthermore, this document only provides directions
for the identification, sanitization and removal of NV storage components. It does not address destruction procedures for
those components. As all of the NV storage components used in the QFX5700 are commercial off-the-shelf (COTS)
components, directions for destruction of those components are left to the customer’s governing department, agency, or
office.

FRU Overview
JNP5700-CHAS
The QFX5700, a 5RU System consists of the following assemblies.
• Routing and control board (RCB)
• FEB card
• Midplane: Control and Power distribution
• Fan tray with FTC
• Fan tray extension card
• Power Supply modules
• PSM extension card
It is designed for front to back cooling.
RCB and the FPC Cards are plugged in from the front side of the chassis. RCB cards are horizontally plugged to the chassis
on top and FPC cards are vertically plugged on bottom.
The Power supply modules and the Fan Trays are plugged from the rear side of the chassis. Both the AC and DC version of
the SKUs are supported. The chassis has 4 PSUs to support N+N mode with feed redundancy and N+1 mode without feed
redundancy. The AC/DC power supplies are plugged horizontally on top of the chassis from rear side through PSU
extension card to the mid plane.
The rear side of the chassis is also loaded with 2 Fan Tray assemblies with fan tray controller. The FAN tray assembly uses
4x 80mmx80mm dual rotor counter rotating fans. The fan tray assembly integrates a Fan controller card along with 4x
Fans and plugs onto the Midplane though fan tray extension card from rear side. The Fan assembly also provides a status
LED to indicate the operating condition of the Fan tray.
FEB cards are placed behind fan tray assemblies and are accessible after respective fan tray assembly is removed.
The QFX5700 uses modular 1RU AC/DC PSU’s. The power supply requires a dedicated air flow channel on top and both
sides of the chassis to intake fresh air to meet the thermal requirements of the PSU. One of the criteria to select the fan
is to manage the system to continue to perform, without any performance degradation under single fan/fan module
failure.
QFX5700-RCB
The QFX5700-RCB integrates the functions of a Routing Engine (RE) and Control Board (CB). RE complex is based on Intel’s
Hewitt Lake Processor.
The RCB performs the following high-level functions:
• As a Routing Engine (RE), it provides the high-performance compute horsepower, memory and storage
infrastructure that enables the operating system to run. It also provides the I/O interfaces that allow the
software to interact with the rest of the system and the outside world.

• As a Control Board (CB), it serves as the backbone of the chassis control and management plane, fanning
out control and management interfaces to all FRUs in the system. It provides the central timing function for
the chassis, distributing system-wide timing while enabling compliance to Synchronous Ethernet (SyncE) and
IEEE 1588.
QFX5700-FEB
QFX5700-FEB uses Trident 4 ASIC and has 64 pair Ortho Direct connectors.
QFX5700-FEB features:
• QFX5700-FEB is based on Trident-4 ASICs with 256 x 50G PAM4 Serdes configuration.
• QFX5700-FEB may operate either using up to 25.78125 Gb/s NRZ or 53.125 GB/s PAM-4 interfaces
QFX5K-FPC-16C
The QFX5K-FPC-16C Interface Card supports 16x 100GE QSFP28 ports. 16x100G FPC ports can come up in 100G, 2x50G,
40G, 4x25G and 4x10G in MACsec and Non MACsec modes. 16x100G FPC supports 100G and 40G optics/DAC.
QFX5K-FPC-4CD
The QFX5K-FPC-4CD Interface Card supports 4x400GE QSFP56-DD ports. 4x400G FPC ports can come up in 400G, 2x200G,
4x100G, 1x200G, 1x100G and 8x50G in MACsec and Non MACsec modes.400G FPC supports 400G optics/DAC and
backward compatible with 100G Optics/DAC.
QFX5K-FPC-20Y
The QFX5K-FPC-20Y Interface Card supports 20x50GE SFP56 ports. QFX5K-FPC-20Y ports can come up in
1G/10G/25G/50GE or SFP/SFP+/SFP28/SFP56 respectively in MACsec and Non MACsec modes. This board will not support
1G mode in Hillside because of PFE rate constraint.

Programmable device
Definition: A programmable logic device (PLD) is an electronic component used to build reconfigurable digital circuits.
Unlike a logic gate, which has a fixed function, a PLD has an undefined function at the time of manufacture. Before
the PLD can be used in a circuit it must be programmed, that is, reconfigured.

Power Down and removal of Non-volatile storage
The QFX5700-RCB has two solid-state drives (SSDs) that store the software images, system logs, and the configuration
files. Before returning a chassis to Juniper Networks as part of a Return Merchandise Authorization (RMA), you have the
option of removing the SSDs and disposing of them according to your own company’s security procedures. Before you
begin this procedure, ensure you have the following tools:
• ESD grounding strap (not provided)
• Antistatic bag or an antistatic mat
• Phillips (+) screwdriver, number 1
Use this procedure to remove the drives from the QFX5700-RCB after the device has shut down and removed from the
chassis (Follow system Power Down section to power down the system).
1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other
3. Place the device on a firm surface such as a workbench or a table.
4. Remove the two screws securing the SSD mezzanine board by using the Phillips (+) screwdriver.

5. Remove the single screw holding the SATA SSD in place and slide the drive out of the plug (see figure below).
SSDs are located at TOP and BOTTOM sides of the mezzanine board.
6. Place the SATA SSD in an electrostatic bag or on an antistatic mat.

7. Place the SSD mezzanine board back on the QFX5700-RCB and tighten the two screws securing the SSD
mezzanine board.
System power down
QFX5700-RCB should be powered down gracefully. Follow the steps below to gracefully power down the system.
1. Connect to QFX5700-RCB by using either console (COM) port or management port (MGMT).
2. Shut down Junos OS Evolved from the external management device by issuing the request system halt
operational mode CLI command. This command shuts down Junos OS Evolved gracefully and preserves
system state information. A message appears on the console, confirming that the operating system has
halted.
