SRX300 Services Gateway Chassis Overview
The SRX300 Services Gateway chassis weighs 4.38 lb. and measures 1.37 in. high, 12.63 in. wide, and 7.52 in. deep.
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 rear of the chassis is provided to connect the services gateway to ground.

1-GbE Ethernet ports
Six LAN ports (0/0 to 0/5)
The ports have the following characteristics:
The ports can be used to:
1-GbE small form-factor pluggable (SFP) ports
Two 1-GbE MACsec-capable SFP ports for network traffic.
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.
Mini-USB console port
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.
