Documentation and Release Notes
To obtain the most current version of all Juniper Networks®technical documentation, see the product
documentation page on the Juniper Networks website at https://www.juniper.net/documentation/.
If the information in the latest release notes differs from the information in the documentation, follow the
product Release Notes.
Juniper Networks Books publishes books by Juniper Networks engineers and subject matter experts.
These books go beyond the technical documentation to explore the nuances of network architecture,
deployment, and administration. The current list can be viewed at https://www.juniper.net/books.
Using the Examples in This Manual
If you want to use the examples in this manual, you can use the load merge or the load merge relative
command. These commands cause the software to merge the incoming configuration into the current
candidate configuration. The example does not become active until you commit the candidate configuration.
If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example
is a full example. In this case, use the load merge command.
If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In
this case, use the load merge relative command. These procedures are described in the following sections.
Merging a Full Example
To merge a full example, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration example into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following configuration to a file and name the file ex-script.conf. Copy the
ex-script.conf file to the /var/tmp directory on your routing platform.
system {
scripts {
commit {
file ex-script.xsl;
}
}
}
interfaces {
fxp0 {
disable;
unit 0 {
family inet {
address 10.0.0.1/24;
}
}
}
}
xi
2. Merge the contents of the file into your routing platform configuration by issuing the load merge
configuration mode command:
[edit]
user@host# load merge /var/tmp/ex-script.conf
load complete
Merging a Snippet
To merge a snippet, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following snippet to a file and name the file ex-script-snippet.conf. Copy the
ex-script-snippet.conf file to the /var/tmp directory on your routing platform.
commit {
file ex-script-snippet.xsl; }
2. Move to the hierarchy level that is relevant for this snippet by issuing the following configuration mode
command:
[edit]
user@host# edit system scripts
[edit system scripts]
xii
3. Merge the contents of the file into your routing platform configuration by issuing the load merge
relative configuration mode command:
[edit system scripts]
user@host# load merge relative /var/tmp/ex-script-snippet.conf
load complete
For more information about the load command, see CLI Explorer.

SRX550 Services Gateway Power over Ethernet
Power over Ethernet (PoE) supports the implementation of the IEEE802.3 af and IEEE802.3 at standards,
which allow both data and electric power to pass over a copper Ethernet LAN cable.
The SRX550 Services Gateway provides PoE ports, which supply electric power over the same ports that
are used to connect network devices. PoE ports allow you to plug in devices that require both network
connectivity and electric power, such as Voice over IP (VoIP) and IP phones and wireless access points.
The PoE ports for the SRX550 Services Gateway reside on the individual XPIMs. The SRX550 Services
Gateway supports the following XPIMs with PoE:
16-Port Gigabit Ethernet XPIM
•
24-Port Gigabit Ethernet XPIM
•
The Services and Routing Engine (SRE) manages the overall system PoE power. You can configure the
services gateway to act as power sourcing equipment to supply the power to the GPIMs connected on
the designated PoE ports.
Table 4 on page 10 lists the SRX550 Services Gateway PoE specifications.

SRX550 Services Gateway Boot Devices and Dual-Root Partitioning Scheme
By default, the SRX550 Services Gateway boots from the following storage media (in order of priority):
12
1. Internal CompactFlash card (default; always present)
2. USB storage key (alternate)
NOTE: When you explicitly boot the services gateway using the CLI and the services gateway
has two USBs installed (one in slot 0 and the second in slot 1), if the USB in slot 0 fails, the
booting sequence will not boot from the second USB installed in slot 1. Instead, the device will
boot using the next storage media in its storage media booting priority list, the internal
CompactFlash card.
The dual-root partitions allow the services gateways to remain functional if there is file system corruption
and facilitate easy recovery of the corrupted file system.
The dual-root partitioning scheme keeps the primary and backup Junos OS images in two independently
bootable root partitions. If the primary root partition is corrupted, the system will be able to boot from
the backup Junos OS image located in the other root partition and remain fully functional.
When the services gateway powers up, it tries to boot Junos OS from the default storage media. If the
device fails to boot from the default storage media, it tries to boot from the alternate storage media. With
the dual-root partitioning scheme, the device first tries to boot Junos OS from the primary root partition
and then from the backup root partition on the default storage media. If both primary and backup root
partitions of a media fail to boot, then the device tries to boot Junos OS from the next available type of
storage media. The services gateway remains fully functional even if it boots the Junos OS from the backup
root partition of storage media.

A Gigabit-Backplane Physical Interface Module (GPIM) is a network interface card (NIC) that installs in the
front slots of the services gateway to provide physical connections to a LAN or a WAN. The GPIM receives
incoming packets from a network and transmits outgoing packets to a network. These modules complement
the onboard Ethernet interfaces to extend the types and port counts of network connections for the LAN
or WAN.
Interface Module Terminology:
GPIM—The Gigabit-Backplane Interface Module (GPIM) includes standard GPIMs that can be installed
•
in a single-high, single-wide GPIM slot that has gigabit connectivity to the system backplane.
XPIM—The XPIM can be installed only in the 10-gigabit GPIM slot 3 or in the 20-gigabit GPIM slot 6. It
•
could be:
A single-high, single-wide LAN switch XPIM that uses one slot
•
A double-high, single-wide LAN switch XPIM that uses two standard slots vertically
•
A double-high, double-wide LAN switch XPIM that uses two standard slots vertically and two standard
•
slots horizontally
NOTE: When installing the 24-Port Gigabit Ethernet XPIM, which uses four slots, you must
install it in the 20-gigabit GPIM slot 6, which refers to the top four slots 5 through 8.
Figure 6 on page 25 shows how the slots on the front panel of the SRX550 Services Gateway are numbered.

CHAPTER 5
Cooling System Description
IN THIS CHAPTER
SRX550 Services Gateway Cooling System | 27
SRX550 Services Gateway Cooling System
The SRX550 Services Gateway cooling system consists of four fixed fans. The fans provide cooling to the
components installed in the services gateway. To function properly, the entire cooling system requires an
unobstructed airflow and proper clearance around the site.
27
The fan controller constantly monitors the temperature of the services gateway and all modules (Mini-PIMs
and GPIMs) installed in the device. Under normal operating conditions, the fans function at lower than full
speed.
If any one of the four fans fails, the services gateway generates a warning but keeps the system running.
If the temperature keeps rising, the services gateway lowers the power consumption by reducing the
performance or shutting down some of the chassis components. However, if the ambient maximum
temperature specification exceeds the warning limit and the system cannot be adequately cooled, then
the services gateway shuts down the system and hardware components completely.

Power System Description
IN THIS CHAPTER
SRX550 Services Gateway Power Supply | 28
SRX550 Services Gateway Power Supply
The SRX550 Services Gateway uses either one AC or one DC power supply unit (PSU). The services
gateway is equipped with one AC power supply (see Figure 10 on page 29) for non-power redundancy. A
second PSU is optional (sold separately) for power redundancy. A second PSU can be used to meet power
requirements exceeding the wattage provided by a single PSU (a nonredundant configuration). The two
power supplies, either both AC or both DC, will load-share and provide power redundancy to the services
gateway, increasing its availability and reliability. If one power supply fails or is removed, the other power
supply redistributes the electrical load without interruption. The services gateway reassesses the power
required to support its configuration and issues errors if the available power is insufficient.
Figure 11 on page 29 shows the diagram of the DC power supply.
28
CAUTION: Do not mix AC and DC power supplies within the same services gateway
because this can damage the device.
All power supplies are hot-swappable and support single or dual redundant power supply versions. Each
power supply is cooled by the system’s fans.

SRX550 Services Gateway Electrical Wiring Guidelines
Table 14 on page 50 describes the factors you must consider while planning the electrical wiring for the
SRX550 Services Gateway at your site.
CAUTION: It is particularly important to provide a properly grounded and shielded
environment and to use electrical surge-suppression devices.
Table 14: Site Electrical Wiring Guidelines for the SRX550 Services Gateway
GuidelineSite Wiring Factor
50
Signaling limitations
Radio frequency
interference (RFI)
Electromagnetic
compatibility (EMC)
To ensure that signaling functions optimally:
Install wires correctly.
•
Improperly installed wires can emit radio interference.
Do not exceed the recommended distances or pass wires between buildings.
•
The potential for damage from lightning strikes increases if wires exceed recommended
distances or if wires pass between buildings.
Shield all conductors.
•
The electromagnetic pulse (EMP) caused by lightning can damage unshielded
conductors and destroy electronic devices.
To reduce or eliminate the emission of RFI from your site wiring:
Use twisted-pair cable with a good distribution of grounding conductors.
•
Use a high-quality twisted-pair cable with one ground conductor for each data signal
•
when applicable, if you must exceed the recommended distances.
Provide a properly grounded and shielded environment and use electrical
surge-suppression devices.
Strong sources of electromagnetic interference (EMI) can cause the following damage:
Destroy the signal drivers and receivers in the device.
•
Conduct power surges over the lines into the equipment, resulting in an electrical
•
hazard.
TIP: If your site is susceptible to problems with EMC, particularly from lightning or radio
transmitters, you might want to seek expert advice.
CAUTION: Some ports are designed for use as intrabuilding interfaces only (Type 2
or Type 4 ports, the battery return connection is to be treated as an Isolated DC return
(that is, DC-I), as defined in GR-1089-CORE) and require isolation from the exposed
OSP cabling. To comply the NEBS requirements and protect against lightening surges
and commercial power disturbances, the intrabuilding port(s) of the device MUST NOT
be metallically connected to interfaces that connect to the OSP or its wiring. The
intrabuilding port(s) of the device is suitable for connection to intrabuilding or
unexposed wiring or cabling only. The addition of primary protectors is not sufficient
protection to connect these interfaces metallically to OSP wiring.

SRX550 Services Gateway Autoinstallation Overview
Autoinstallation provides automatic configuration for a new SRX550 Services Gateway that you connect
to the network and turn on, or for a services gateway configured for autoinstallation. The autoinstallation
process begins whenever a services gateway is powered on and cannot locate a valid configuration file in
the CompactFlash. Typically, a configuration file is unavailable when a services gateway is powered on for
the first time or if the configuration file is deleted from the CompactFlash. The autoinstallation feature
enables you to deploy multiple services gateways from a central location in the network.
If you are setting up many services gateways, autoinstallation can help automate the configuration process
by loading configuration files onto new or existing devices automatically over the network. You can use
the CLI to configure a services gateway for autoinstallation. The J-Web interface does not include pages
for the autoinstallation feature.
For the autoinstallation feature to work, you must store one or more host-specific or default configuration
files on a configuration server in the network and have a service available—typically Dynamic Host
Configuration Protocol (DHCP)—to assign an IP address to the services gateway.
Autoinstallation begins automatically when you connect to the Ethernet port labeled 0/0 (interface
ge-0/0/0) on a new services gateway connected to the network and power on the services gateway. To
simplify the process, you can explicitly enable autoinstallation on a services gateway and specify a
configuration server, an autoinstallation interface, and a protocol for IP address acquisition.
63
NOTE: Autoinstallation is enabled on all ports of the services gateway. If you do not want to
use the autoinstallation feature, you must delete it using the CLI. For more information about
the autoinstallation feature, see the Initial Configuration for Security Devices.

Installing an AC Power Supply on the SRX550 Services Gateway
g034119
To install an AC power supply:
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to
one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic
Discharge Damage to the SRX550 Services Gateway.
2. Using both hands, slide the power supply straight into the chassis until the power supply is fully seated
in the chassis slot. The power supply faceplate should be flush with any adjacent power supply faceplate
(see Figure 17 on page 72).
3. Attach the power cord to the power supply.
4. Route the power cord along the cable restraint toward the left or right corner of the chassis. If they
are needed to hold the power cord in place, thread plastic cable ties, which you must provide, through
the openings on the cable restraint.
72
5. Attach the power cord to the AC power source, and switch on the dedicated facility circuit breaker for
the power supply. Follow the ESD and connection instructions for your site. If the power supply is
correctly installed and functioning normally, the POWER LED lights steadily.
Figure 17: Installing an AC Power Supply on the SRX550 Services Gateway
Installing a DC Power Supply on the SRX550 Services Gateway
g034121
To install a DC power supply:
1. Ensure that the voltage across the DC power source cable leads is 0 V and that there is no chance that
the cable leads might become active during installation. To ensure that all power is off, locate the circuit
breaker on the panel board that services the DC circuit, switch the circuit breaker to off position (O),
and tape the switch handle of the circuit breaker in the off position.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to
one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic
Discharge Damage to the SRX550 Services Gateway.
3. Orient the power supply so that the locking lever is on the left, as shown in Figure 18 on page 73.
Figure 18: Installing a DC Power Supply on an SRX550 Services Gateway
73
4. Using both hands, slide the power supply straight into the chassis until the power supply is fully seated
in the chassis slot. The power supply faceplate should be flush with any adjacent power supply faceplate.
5. Tighten the captive screws on the lower edge of the power supply faceplate.
6. Remove the clear plastic cover protecting the terminal studs on the faceplate.
7. Verify that the DC power cables are correctly labeled before making connections to the power supply.
In a typical power distribution scheme where the return is connected to chassis ground at the battery
plant, you can use a multimeter to verify the resistance of the –48V and RTN DC cables to chassis
ground:
The cable with very large resistance (indicating an open circuit) to chassis ground will be –48V.
•
The cable with very low resistance (indicating a closed circuit) to chassis ground will be RTN.
•
CAUTION: You must ensure that power connections maintain the proper polarity.
The power source cables might be labeled (+) and (–) to indicate their polarity.
There is no standard color coding for DC power cables. The color coding used by
the external DC power source at your site determines the color coding for the leads
on the power cables that attach to the terminals on the power supply.
8. Connect DC power cables to the A+ and A- terminals:
74
a. Remove the screws and square washers from the A+ and A- terminals. Use a Phillips (+) screwdriver,
number 2. The square washers are permanently attached to the screws.
b. Secure each power cable lug to the appropriate terminal with a screw. Apply between 23 lb-in.
(2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each screw.
Secure the positive (+) DC source power cable lug to the A+ (return) terminal.
•
Secure the negative (–) DC source power cable lug to the A- (input) terminal.
•
Figure 19: Connecting DC Power Cables
g034111
75
9. Replace the clear plastic cover over the terminal studs on the faceplate.
10. Verify that the power cables are connected correctly, that they are not touching or blocking access to
services gateway components, and that they do not drape where people could trip on them.
11. Remove the tape from the switch handle of the circuit breaker on the panel board that services the
DC circuit and switch the circuit breaker to the on position ( | ). Observe the status LEDs on the power
supply faceplate. If the power supply is correctly installed and functioning normally, the POWER LED
lights green steadily on the services gateway front panel.
NOTE: If more than one power supply is being installed, turn on all power supplies at the same
time.
