The ACX1100 Universal Metro Routers are principally designed to provide superior management for rapid provisioning to the access network.
Juniper ACX1100 Router Overview
ACX1100 is a very good router from the Juniper ACX series.
Key Advantages
- Source NAT support
- IPsec
- Fan-less design (quiet operation)
Acquisition
I got mine via eBay at an extremely affordable price. The only issue was an alarm LED—turns out it lights up when there’s no console management cable connected or a second power-supply plugged in, which actually worked in my favor.
“Maybe it’s not the smallest router in the world, but being fan-less is another plus.”
Firmware
- Upgraded to Junos 21.2R3.8
- Originally found the firmware online (Google it!)
Lab Use
Since I don’t have any production use for it, and I don’t want to sell it, I’m using it as a lab device.
Bonus: It supports Juniper Logical Systems.
