Questions & Answers
What is the RE-S-1800X4-32G-BB Routing Engine?
The RE-S-1800X4-32G-BB is a base-bundle routing engine for Juniper MX series routers featuring a quad-core 1.8 GHz CPU and 32 GB of DRAM.
Which Juniper MX routers support the RE-S-1800X4-32G-BB?
It is compatible with MX240, MX480, MX960, MX2020, and MX10003 platforms when used in the designated RE slot.
How do I install the RE-S-1800X4-32G-BB in my MX router?
Power down the router, insert the Routing Engine into the RE slot until it clicks, reconnect power, and verify operation via the console CLI.
What Junos OS versions does the RE-S-1800X4-32G-BB support?
It supports Junos OS Release 18.1R1 or later for full functionality, performance improvements, and security updates.
What performance benefits does this routing engine provide?
With a 1.8 GHz quad-core CPU and 32 GB DRAM, it accelerates control-plane processing, scales to large BGP tables, and improves route convergence times.
Is the RE-S-1800X4-32G-BB hot-swappable?
Yes. It supports in-service insertion and removal (IS-IR) on compatible MX systems to minimize downtime.
What is included in the Base Bundle?
The base bundle includes the Routing Engine, mounting bracket, installation guide, and default software license; power and network cables are sold separately.
How much power does the RE-S-1800X4-32G-BB consume?
Typical power consumption is 75 W, with a maximum draw of 90 W under full CPU and memory load.
Does the RE-S-1800X4-32G-BB support remote management?
Yes. It provides an RJ-45 console port, dedicated management Ethernet port, and out-of-band management capabilities via Junos SSH.
How do I reset the Routing Engine to factory defaults?
From the Junos CLI, run ‘request system zeroize all’ to erase configurations and return the engine to factory settings.
What warranty covers the RE-S-1800X4-32G-BB?
Juniper provides a one-year limited hardware warranty, with options to extend support through J-Care or J-Premium service plans.
Can I upgrade the memory on the RE-S-1800X4-32G-BB?
No. The 32 GB DRAM is factory-soldered and not field-upgradeable; future models may offer higher memory configurations.
What routing protocols are optimized on this engine?
It natively accelerates BGP, OSPF, IS-IS, RSVP-TE, and MPLS LDP for high-scale service-provider and enterprise deployments.
What physical dimensions and weight should I expect?
The module measures 36 cm (W) × 20 cm (D) × 3 cm (H) and weighs approximately 1.2 kg.
How does the RE-S-1800X4-32G-BB improve network security?
It enforces control-plane policing, hardware-accelerated packet filtering, and integrates Junos security policies for DDoS mitigation.
Which environments is the RE-S-1800X4-32G-BB best suited for?
Ideal for service-provider backbones, data-center interconnects, and large enterprise cores requiring high route scale and fast convergence.
