ACX7348 Routing Engine

SUMMARY Learn about the ACX7300 Routing Engine and its specifications.

The ACX7348 Routing Engine provides control plane and chassis management functions. The Routing Engine provides high-performance compute horsepower and memory and storage infrastructure that enable the operating system to run. You can install one or two Routing Engines on the router. A redundant system hosts two Routing Engines, one being the primary and the other, the backup. The ACX7348 Routing Engine is a hot-pluggable FRU.

Each Routing Engine includes the following internal components:

CPU—High-performance 2.2-GHz Intel 4 Core ICX-D CPU
DRAM—2x32-GB DDR4 RAM
Solid-state drive (SSD)—One 100-GB SATA SSD

1 — USB port	6 — ACT LED
2 — Management (MGMT) port	7 — ALM LED
3 — Console (CON) port	8 — PWR LED
4 — Reset button	9 — STS LED
5 — Online/Offline button

The Routing Engine ports function as follows:

CON—Connects the Routing Engine to a system console through a serial 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. The port uses an autosensing RJ-45 connector to support 10-Mbps, 100-Mbps, or 1000-Mbps connections. Two small LEDs (an activity LED and a link LED) on the port indicate that the connection is in use.

The link LED is:
- Green (steady) when the 1000-Mbps link is up.
- Orange (steady) when the 100-Mbps link is up.
- Off when the link is down.
- Off and the ACT LED is yellow (blinking) when the 10-Mbps link is up.
The activity LED is:
- Yellow (blinking) when traffic is passing through the port.
- Off when link is down.
- Yellow (steady) when traffic is not passing through the port.
Both activity and link LEDs are off when the link is down.
USB—Provides a removable media interface through which you can install Junos OS Evolved manually. Junos OS Evolved supports USB version 2.0 and later.

The Routing Engine also has these buttons on its front panel:

Reset button—When pressed, reboots the Routing Engine as follows:
- Short press reboots the Routing Engine.
- When pressed for more than 10 seconds, the Routing Engine reboots with an option for BIOS recovery.
Online/Offline button—When the Routing Engine is offline and if the button is pressed (short press), the Routing Engine starts booting. When the Routing Engine is online and if the button is pressed for four seconds or more (long press), the Routing Engine shuts down.

Routing Engine LEDs

The LEDs labeled STS, ALM, ACT, PWR are located on the faceplate of the Routing Engine.
