Routing Engine SRX5K-RE3-128G Specifications

The Routing Engine maintains the routing tables, manages the routing protocols used on the device, controls the device interfaces, controls some chassis components, and provides the interfaces for system management and user access to the device.

Figure 1 shows the SRX5K-RE3-128G Routing Engine.

Description	Routing Engine for SRX5400, SRX5600, and SRX5800 Services Gateways, based on Intel’s Haswell-EP CPU with 6 cores, and 128GB of DDR4 memory. It provides increased control plane performance and scalability along with virtualization features in the SRX Series 5000 line of chassis.
Software release	Junos OS Release 19.3R1 and later
Cables and connectors	Slot for Routing Engine AUX–Connects the Routing Engine to a laptop, a modem, or another auxiliary device through a cable with an RJ-45 connector. CONSOLE–Connects the Routing Engine to a system console through a cable with an RJ-45 connector. MGMT–Connects the Routing Engine through an Ethernet connection to a management LAN (or any other device that plugs into an Ethernet connection) for out-of-band management.
Controls	RESET button–Reboots the Routing Engine when pressed.
Supported slots	Front panel slot in an SCB installed in: SRX5400: Bottom slot 0 SRX5600: Bottom slots 0 or 1 SRX5800: Center slots 0 or 1 Note: The services gateway host subsystem Routing Engine must be installed in the SCB in slot 0. A Routing Engine installed in an SCB in slot 1 only enables dual control links in chassis cluster configurations. Note: In the SRX5600 or SRX5800 Services Gateways chassis cluster configurations, dual control links functionality is not supported if you mix SRX5K-RE-1800X4 and SRX5K-RE3-128G Routing Engines. To support dual control links you have to install two SRX5K-RE3-128Gs.
Power requirement	110 W
Weight	2.69 lb (1.22 kg)
Serial number location	The serial number label is located as shown in Figure 2. Figure 2: SRX5K-RE3-128G Serial Number Label

SRX5K-RE3-128G Routing Engine Components

Each Routing Engine consists of the following components:

• CPU—Runs Junos OS to maintain the routing tables and routing protocols.

• EEPROM—Stores the serial number of the Routing Engine.

• DRAM—Provides storage for the routing and forwarding tables and for other Routing Engine processes.

• One 10-Gigabit Ethernet interface between the Routing Engine and Switch Control Board.

• Extractor clips—Control the locking system that secures the Routing Engine.

• Interface ports—The AUX, CONSOLE, and MGMT ports provide access to management devices. Each Routing Engine has one 10/100/1000-Mbps Ethernet port for connecting to a management network, and two asynchronous serial ports—one for connecting to a console and one for connecting to a modem or other auxiliary device.

  Note

  The control interface names differ based on the routing engine:

  • For RE2, the control interfaces are displayed as em0 and em1.

  • For RE3, the control interfaces are displayed as ixlv0 and igb0.

  For more information, see show chassis cluster interfaces.

• Status LEDs—Table 1 describes the functions of the ONLINE, OK/FAIL, MASTER, DISK1, and DISK2 LEDs.

• ONLINE/OFFLINE button—Takes the Routing Engine online or offline when pressed.

  Note

  The ONLINE/OFFLINE button must be pressed for a minimum of 4 seconds.

• USB1 and USB2 ports—Provide a removable media interface through which you can install Junos OS manually. Junos OS supports USB versions 3.0, 2.0, and 1.1.

• RESET button—Reboots the Routing Engine when pressed.

• SSD1 (primary) and SSD2 (secondary) Solid-state drives (SSD)—Two 200-GB each slim solid-state drives that provide storage for software images, configuration files, microcode, log files, and memory dumps. The Routing Engine reboots from SSD2 when boot from primary SSD1 fails.

• Captive screws—Secures the Routing Engine.

SRX5K-RE3-128G Routing Engine LEDs

Each Routing Engine has four LEDs that indicate its status. The LEDs, labeled ONLINE, OK/FAIL, MASTER, DISK1, and DISK2, are located directly on the faceplate of the Routing Engine. Table 1 describes the Routing Engine LEDs and their states.

SRX5K-RE3-128G Routing Engine Boot Sequence

Booting in a SRX5K-RE3-128G Routing Engine follows this sequence—the USB device, SSD1, SSD2, and LAN. SSD1 is the primary boot device. The boot sequence is tried twice for SSD1 and SSD2.
