Letter of Volatility EX4100-F-24P/T  2/2/2023 
   
   
  UNCLASSIFIED   
 
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 EX4100-F-24P/T platform. 
Non-Volatile  (NV)  storage  is  a  system  memory  that  can  store  user  data 
information and system configuration data even when system not powered.  
Volatile (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  EX4100-F-24P/T  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 the NV storage components used in the EX4100-F-24P/T 
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 
Juniper Networks EX4100-F-24P/T Ethernet Switches provide connectivity for 
high-density  environments  and  scalability  for  growing  networks.  These 
switches can be deployed wherever you need high density of Gigabit Ethernet 
ports or redundancy. Typically, EX4100-F-24P/T switches are used in large 
branch  offices,  campus  wiring  closets,  and  data  centers.  In  datacenters, 
EX4100-F-24P/T switches can be positioned as top-of-rack switches; the top 
devices in a rack to provide connectivity for all the devices in the rack. Juniper 
Networks SRX Series Ethernet Switches run Junos OS, which provides Layer2 
and Layer3 switching, routing, and security services. 
The  24-ports  EX4100-F-24P/T  switch  with gigabit  ports and  provide built-in 
Ethernet  network  ports,  0-23  built-in  1G  ports,  0-3  built-in  4x10G  SFP+ 
(Uplink-ports), 0-3 built-in 4x10G SFP+ (Stack ports) Ethernet network ports. 
Ethernet network ports support 1Gbps,10Gbps EX4100-F-24P/T is designed to 
fit in a standard 19" rack.
