SRX345 Services Gateway Chassis Overview
The SRX345 Services Gateway chassis is a rigid sheet metal structure that houses all of the other services gateway components. The chassis installs in standard 800–mm (or larger) enclosed cabinets, 19 in. equipment racks, or telecommunications open-frame racks.
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.

Reset Config button
Returns the services gateway to the rescue configuration or the factory-default configuration.
Use the management (MGMT) port to connect to the device over the network.
Four slots for Mini-PIMs. Mini-PIMs can be used to provide LAN and WAN functionality along with connectivity to various media types.
Note: The SRX345 device with dual AC power supplies ships with tamper-proof labels.
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.
1-GbE small form-factor pluggable (SFP) ports
Eight 1-GbE MACsec-capable SFP ports for network traffic.
1-GbE Ethernet ports
Eight LAN ports (0/0 to 0/7), which are MACsec capable.
The ports have the following characteristics:
The Gigabit Ethernet ports can be used to:
The services gateway has one USB port that accepts a USB storage device.
Indicate component and system status at a glance.
Use the Power button to power on or power off the services gateway.

SRX345 Services Gateway 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.
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 SRX345 Services Gateway:
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)
Gigabit-Backplane Physical Interface Modules (GPIMs) are not supported on the SRX345 Services Gateway.
