SSR1400 Appliance Overview

The Juniper Networks SSR1400 is a 1-U fixed-configuration appliance that is ideal for medium data center or campus deployments. Powered by the Juniper Session Smart Router (SSR) software, the SSR1400 provides secure and resilient WAN connectivity.


To use the SSR1400, you must purchase the SSR software subscription license that is sold separately. You can onboard and monitor the SSR1400 in a cloud network by using Juniper Mist™.

Benefits of SSR1400

  • Zero Trust Security (ZTS)—The SSR1400 ensures ZTS by authenticating all routes and encrypting all session traffic. Applications, devices, or users cannot initiate any session that does not comply with the authentication policies and access rules. The SSR1400 supports Layer 2 through Layer 5 stateful firewall functions, including DoS/DDoS protection, NAT, encryption, VPN, and traffic filtering.

  • Adaptive encryption—The SSR1400 automatically detects traffic encrypted using HTTPS or IPsec and does not re-encrypt such traffic. This capability results in improved performance and reduced overhead due to double encryption.

  • Simplified onboarding and monitoring with Juniper Mist WAN Assurance—You can quickly onboard the SSR1400 to the Mist Cloud using the claim code (QR code). This helps in reducing the operational complexity and simplifying the deployment and configuration process.


    Starting from SSR Release 6.0, you can manage the SSR1400 using Juniper Mist WAN Assurance.

Field-Replaceable Units in SSR1400 Appliances

Field-replaceable units (FRUs) are components that you can replace at your site. Following are the two types of the SSR1400 FRUs:

  • Hot-insertable and hot-removable—You can remove and replace these components without powering off the appliance or disrupting the appliance function.

  • Hot-pluggable—You can remove and replace these components without powering off the appliance, but the appliance function is interrupted until you replace the component.

The FRUs in SSR1400 appliances are:

  • Fans (hot-insertable and hot-removable)

  • Power supplies (hot-insertable and hot-removable)

  • Transceivers (hot-pluggable)
