SRX340 Chassis

SRX340 Firewall Chassis Overview

The SRX340 Firewall chassis is a rigid sheet metal structure that houses all of the other services gateway components. The chassis measures 1.72 in. (4.36 cm) high, 17.36 in. (44.09 cm) wide, and 14.57 in. (37.01 cm) deep (from the front to the rear of the chassis). The chassis installs in standard 800–mm (or larger) enclosed cabinets, 19 in. equipment racks, or telecommunications open-frame racks.

CAUTION:

Before removing or installing components of a functioning services gateway, attach an electrostatic discharge (ESD) strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the device.

The services gateway must be connected to earth ground during normal operation. The protective earthing terminal on the side of the chassis is provided to connect the services gateway to ground.

Description

1

Reset Config button

Returns the services gateway to the rescue configuration or the factory-default configuration.

2, 8

Console ports

  • Serial—Connects a laptop to the services gateway for CLI management. The port uses an RJ-45 serial connection and supports the RS-232 (EIA-232) standard.

  • USB—Connects a laptop to the services gateway for CLI management through a USB interface. The port accepts a Mini-B type USB cable plug. A USB cable with Mini-B and Type A USB plugs is supplied with the services gateway.

    To use the mini-USB console port, you must download a USB driver to the management device from the Downloads page at https://www.juniper.net/support/downloads/?p=junos-srx#sw.

    To download the driver for Windows OS, select 6.5 from the Version drop-down list.

    To download the driver for Mac OS, select 4.10 from the Version drop-down list.

3

Management port

Use the management (MGMT) port to connect to the device over the network.

4

Mini-PIM slots

Four slots for Mini-PIMs. Mini-PIMs can be used to provide LAN and WAN functionality along with connectivity to various media types.

5

ESD point

For personal safety, while working on the services gateway, use the ESD outlet to plug in an ESD grounding strap to prevent your body from sending static charges to the services gateway.

6

1-GbE small form-factor pluggable (SFP) ports

Eight 1-GbE MACsec-capable SFP ports for network traffic.

7

1-GbE Ethernet ports

Eight LAN ports (0/0 to 0/7), which are MACsec capable.

The ports have the following characteristics:

  • Use an RJ-45 connector

  • Operate in full-duplex and half-duplex modes

  • Support autonegotiation

The ports can be used to:

  • Function as front-end network ports

  • Provide LAN and WAN connectivity to hubs, switches, local servers, and workstations

  • Forward incoming data packets to the services gateway

  • Receive outgoing data packets from the services gateway

9

USB port

The services gateway has one USB port that accepts a USB storage device.

LEDs

Indicate component and system status at a glance.

11

Power button

Use the Power button to power on or power off the services gateway.

SRX340 Firewall Interface Modules Overview

Mini-Physical Interface Modules (Mini-PIMs) are field-replaceable network interface cards (NICs) supported on the SRX300 line of services gateways. You can easily insert or remove Mini-PIMs from the front slots of the services gateway chassis. The Mini-PIMs provide physical connections to a LAN or a WAN. The Mini-PIMs receive incoming packets from the network and transmit outgoing packets to the network. During this process, they perform framing and line-speed signaling for the medium type.

CAUTION:

The Mini-PIMs are not hot-swappable. You must power off the services gateway before removing or installing Mini-PIMs.

The following Mini-PIMs are supported on the SRX340 Firewall:

  • 1-Port Serial Mini-Physical Interface Module (SRX-MP-1SERIAL-R)

  • 1-Port T1/E1 Mini-Physical Interface Module (SRX-MP-1T1E1-R)

  • 1-Port VDSL2 (Annex A) Mini-Physical Interface Module (SRX-MP-1VDSL2-R)

  • LTE Mini-Physical Interface Module (SRX-MP-LTE-AE and SRX-MP-LTE-AA)

  • Wi-Fi Mini-Physical Interface Module (SRX-MP-WLAN-US, SRX-MP-WLAN-IL, and SRX-MP-WLAN-WW)

Note:

Gigabit-Backplane Physical Interface Modules (GPIMs) are not supported on the SRX340 Firewall.

For more information on the Mini-PIMs, see the SRX300 Series and SRX550 High Memory Gateway Interface Modules Reference.
