SRX4300 Firewall Overview

SRX4300 Firewall Overview

The SRX4300 Firewall is a midrange next-generation firewall that consolidates firewall and security features. The SRX4300 is ideal for small to medium enterprise edge, campus edge, data center edge, and secure VPN router deployments for distributed enterprise use cases.

The SRX4300 is a 1-U chassis with the following port configurations:

  • Eight 1/2.5/5/10 Gigabit Ethernet (GbE) BASE-T ports

  • Eight 1/10GbE SFP+ ports

  • Four 1/10/25GbE SFP28 ports

  • Six 4x10/4x25/2x50/40/100GbE QSFP28 ports

  • Two 1GbE SFP high availability (HA) ports

All ports are Media Access Control Security (MACsec)-capable ports. The SRX4300 ships with a 120-GB SSD and a 960-GB SSD that are not field replaceable.

The SRX4300 Firewall is available in both AC and DC models. The SRX4300 runs the Junos OS and provides next-generation firewall capabilities including application identification (AppID), User Firewall (UserFW), intrusion prevention system (IPS), Content Security, and so on. It also provides advanced threat detection and mitigation capabilities through Juniper Advanced Threat Prevention Cloud (Juniper ATP Cloud).

You can manage the SRX4300 using Juniper® Security Director on Premise, Juniper® Security Director Cloud, J-Web, and the CLI.

Field-Replaceable Units in SRX4300

Field-replaceable units (FRUs) are components that you can replace at your site. The SRX4300 supports the following FRUs:

  • Fan modules

  • Power supply units (PSUs)

  • Transceivers

You can remove and replace the power supply units, fan modules, and transceivers without powering off the device or disrupting the device functions.

CAUTION:

  • Replace a failed PSU with a new PSU within 5 minutes of removal of the failed PSU. When a PSU fails, the device continues to operate with only one PSU running. You need quick replacement of the PSU to maintain power redundancy.

  • The time within which you must replace a failed fan module depends on the ambient temperature. Check the temperature of the CB 0 TMP75 Inlet Right sensor in the show chassis environment command output.

    If the temperature is up to 104°F (40°C), you must replace the fan module within 2 minutes. If the temperature is above 104°F (40°C), you must replace the fan module within 40 seconds.

Benefits of SRX4300 Firewall

  • Deployment flexibility—The SRX4300 integrates carrier-class routing and feature-rich switching in a single platform. You can install the SRX4300 in enterprise edge, campus edge, and data center edge deployments.

  • Advanced threat prevention—You can secure your network with Juniper ATP Cloud integrated with the SRX4300. Juniper ATP Cloud provides advanced threat mitigation and detection capabilities, which help protect your network against potential vulnerabilities such as zero-day attacks and other unknown threats.
