SRX4200 Services Gateway Chassis Overview
The 4200 Services Gateway chassis is a rigid sheet metal structure that houses all the other hardware components. The chassis measures 1.75 in. high, 17.48 in. wide, and 25 in. deep. The chassis installs in standard 600-mm deep (or larger) enclosed cabinets or 19-in. equipment 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.

Gigabit Ethernet port to connect to the device over the network.
Two USB 2.0 ports that accept a USB storage device.
Two 10-Gigabit Ethernet ports, CTL (control port) and FAB (fabric port), to synchronize data and maintain state information in a chassis cluster setup. These ports support enhanced small form-factor pluggable (SFP+) transceivers.
Eight 1-Gigabit Ethernet/10-Gigabit Ethernet SFP+ ports for network traffic.
Indicate component and system status at a glance.
Connects a laptop to the services gateway for CLI management. The port uses an RJ-45 serial connection, is configured as DTE, and supports the RS-232 (EIA-232) standard.
Returns the services gateway to the factory-default configuration.

Connects the services gateway chassis to earth ground.
Use the Power switch to power on or power off the services gateway.
Alarm Off button
Use this button to turn off an alarm triggered because of an abnormal DC output voltage caused by any of the following:
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.
Four fan trays for cooling the services gateway and its components. Each fan tray contains two fans.
Three fan trays are required for proper air flow across the chassis internal components. The fourth fan tray provides redundancy.
Two power supply slots. Each power supply contains a power cord outlet. Two 650-W DC or AC power supplies are provided with the services gateway.
