1 INTRODUCTION
1.1 Purpose
The purpose of this document is to provide direction to identify and remove all
non-volatile (NV) storage from the Juniper Networks NFX250-S1 platform. Non-
Volative (NV) storage is a system memory that can store user data information
and system configuration data even when system not powered. Volative (V)
storage is a system memory that only retains data or its contents while system
powered but when system powered off or interrupted, its data or contents are
immediately lost.
1.2 Scope
This document only addresses the NFX250-S1 platform. While other platforms
offered by Juniper Networks may contain similar hardware components, this
document only applies to these devices. Furthermore, this document only
provides direction for the identification 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 NFX250-S1 are commercial off-the-shelf
(COTS) components, directions for destruction of those components are left to
the governing Department, Agency, or Office.
2 EQUIPMENT OVERVIEW
2.1 Identification of Chassis
NFX250 devices are available in two compact 1 U models that provide VNF and
Packet Forwarding Engine capacity, and a rich set of Layer 2 and Layer 3
features. The performance of the control plane running on all NFX250 devices is
enhanced by the 2.0 GHz 6-core Intel CPU. NFX250-S1 has 16 GB of memory
and 100 GB of enterprise grade solid-state drive (SSD) storage.
NFX250 device has Eight 1-GbE network ports, two 1-GbE RJ-45 ports which
can be used as either access ports or as uplinks, two SFP ports, two SFP+ ports,
and one management port. NFX250 device has a 1 U form factor and comes with
built-in fans and power supply.

2.2 Description of Field Replaceable Units (FRU)
NFX250-S1 and NFX250-S2 doesn't have any Field replaceable units
None of these components contain NV RAM. All NV RAM is either
soldered or installed onto the system board.
3 POWER DOWN AND REMOVAL OF NON-VOLATILE STORAGE
In order to ensure that no user data or system configurations remain resident on
a NFX250-S1 platform, the following steps must be performed:
1. Power must be removed from the system to clear all volatile storage
2. The SATA Flash modules must be removed from the system board
sockets
A detailed process is included in the following sections.
3.1 System Power Down
Power down the system by removing any connected power cords from power
supply.

3.2 Disassembly of the NFX250-S1 Chassis and Identification of NV
storage
The NFX250-S1 does contain NV storages that is replaceable.In order to access
the memory for removal, refer to the following steps:
1. Remove the power supplies from the system.
2. Remove the ear-mounts on both left and right side of the chassis if any.
3. Remove the six screws from the top of the system (figure 3-1)

3.3 Removal of the SATA FLASH and SPI FLASH from the System Board
Once the NV storages has been located, follow the instructions below.
a) Use screw driver to unscrew the screw and remove the SATA SSD
module
NOTE : Before removal, ensure J-TAC and the appropriate account team has
been notified of your intentions.
