Physical Specification

Value

Chassis height

3.5 in. (8.8 cm)

Chassis width

17.5 in. (44.4 cm)

Chassis depth

18.2 in. (46.2 cm)

Chassis weight (includes one power supply without any GPIMs or Mini-PIMs)

21.96 lb. (9.96 kg)
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. Additional grounding is provided to an AC-powered services gateway when you plug its power supply into a grounded AC power receptacle.

Serial Console Port

Left side of the front chassis panel

Connects a laptop to the services gateway for CLI management. The port uses an RJ-45 serial connection, is configured as data terminal equipment (DTE), and supports the RS-232 (EIA-232) standard.

3

Mini-USB Console Port

Left side of the front chassis panel

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 plug is supplied with the services gateway. To use the USB console port, you must download a USB driver to the management device from the Downloads page. To download the driver for Windows OS, select 6.5 from the Version drop-down list. To download the driver for macOS, select 4.10 from the Version drop-down list.

4 SFP Ethernet ports:

  • Port labeled 0/6

  • Port labeled 0/7

  • Port labeled 0/8

  • Port labeled 0/9

Provides link speeds of 10/100/1000 Mbps.

Middle of the front chassis panel, lower edge

The SFP Ethernet ports have the following characteristics:

  • Operate in full-duplex and half-duplex modes.

  • Support flow control.

  • Support autonegotiation.

The SFP Ethernet ports can:

  • 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.

RESET CONFIG Button

Left side of the front chassis panel

Returns the services gateway to the rescue configuration or the factory default configuration. For more information, see Resetting the SRX550 High Memory Services Gateway.

11

Power button

Left side of the front chassis panel

Use the Power button to shut down the services gateway.

On a services gateway that has been previously shut down using the Power button, the services gateway starts up when the power button is pressed again.

Warning:

The Power button does not shut off power to the power supplies or the midplane. You must remove the power cables or power cords to completely shut down the services gateway. The DC OK LED light on the power supply unit (PSU) changes from green to amber indicating that the software has stopped running. After the software has stopped running, you can safely remove any GPIMs or Mini-PIMs from the services gateway.

12

USB 0 and USB 1 ports

Left side of the front chassis panel

The services gateway has two USB ports, labeled USB 0 and USB 1, that accept a USB storage device. These USB ports accept USB flash drives with Type A plugs. When the USB drive is installed and configured, it automatically acts as the secondary boot device if the primary CompactFlash card fails on startup.

Note:

You must install Junos OS on the USB storage device to use it as the secondary boot device. The services gateway supports the following USB devices:

  • Lexar 2 GB

  • Juniper Networks 2 GB

Depending on the capacity of the USB drive, you can also configure it to receive core files generated during a failure.

13

Electrostatic discharge (ESD) outlet

Left side of the front chassis panel

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, which will damage the device.
