: Resolves bugs where RADIUS accounting server tracking fails or disconnects intermittently.
Users have reported issues with older JL381A firmware versions, including:
Firewall blocking UDP port 69. Solution: Temporarily disable Windows Firewall or add an inbound rule allowing TFTP.
Before updating the firmware on your 1920S switch, it is highly recommended to take the following steps:
as the transfer protocol (this allows you to upload the file directly from your browser). Software Image as the file type. to select the file you downloaded from HPE. 4. Apply and Reboot
is also widely used as a stable release for those coming from the older PD.01 software branch.

Set the CH341A speed to “Slow” (under 1 MHz) to avoid bus errors with long wires.
You can update your switch using three primary methods depending on your environment. 1. Web Interface (Recommended for Small Sites)
: Before first use, charge the JL381A smartwatch fully, which typically takes 2-3 hours. A full charge during its first use ensures a stable setup and helps future updates run smoothly.
Updates post-version 02.06 resolved several "unexpected restart" bugs that occurred during high uptime periods.
Keeping your firmware updated to current releases addresses systemic errors like packet-buffer memory drops, unauthorized Web GUI authentication bypasses, and unstable Spanning Tree Protocol (STP) topologies. Where to Safely Download Authentic JL381A Firmware
Unlike newer cloud-only models, the 1920S series runs on specialized local-management software branches. The primary firmware release branches are:
Homelab Note: If you run this hardware in a home-lab or test setting, HPE typically requires an active user account to download standard packages. To circumvent account validation blocks, avoid using temporary or disposable free email domains when creating your profile. Pre-Upgrade Checklist: Minimize Network Downtime
But like any Layer 3 switch, its soul lives in the . Here is everything you need to know about keeping your JL381A secure, stable, and speedy.
The 2930F series runs on the ArubaOS-Switch operating system (formerly ProVision ASIC). Unlike consumer routers that hide firmware updates behind vague "stability improvements," the JL381A firmware changelogs are dense with critical fixes for:
