Keeping Your Network Sharp: A Guide to Updating HPE 1920S (JL381A) Firmware HPE OfficeConnect 1920S 24G 2SFP Switch (JL381A)

is a workhorse for small to mid-sized businesses. However, like any critical piece of hardware, its performance and security rely on keeping its firmware up to date. If you’ve been putting off that update, here is a quick guide to getting it done safely. Why Update? Firmware updates for the 1920S series typically address: Security Vulnerabilities: Patching exploits that could compromise your network. Bug Fixes:

Resolving intermittent connectivity or PoE (Power over Ethernet) issues. Feature Enhancements:

Improving the Web Management interface or SNMP capabilities. Pre-Update Checklist Before you begin, ensure you have the following: Backup Your Configuration:

Never start an update without saving your current settings. Navigate to Maintenance > Backup and Update Manager in the web interface. Verify the Model: Confirm your unit is specifically the The Correct File: Download the latest image file directly from the HPE Support Center The Update Process (Step-by-Step) 1. Access the Web Interface

Connect your PC to the switch and log in. The default management IP is often 192.168.1.1 192.168.2.10 jl381a firmware

, depending on your initial setup. If you haven't set a password, the default username is with no password. 2. Navigate to Firmware Management Maintenance tab and select Backup and Update Manager 3. Upload the Firmware as the action.

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

Once the upload is complete, the switch will ask if you want to set the new image as the image. Confirm this, then navigate to Maintenance > Reboot to apply the changes. Important:

Do not power off the switch during the reboot. The process usually takes 2–5 minutes. Post-Update Verification After the switch reboots, log back in and check the System Information page. Verify that the Software Version matches the version you just uploaded. Troubleshooting Tip

Why the JL381A Firmware Matters More Than You Think

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: Keeping Your Network Sharp: A Guide to Updating

• Security vulnerabilities (DoS attacks, authentication bypasses).
• PoE negotiation issues (especially for IP cameras or VoIP phones).
• Stacking stability (when using the 2930F in a chain).
• SFP+ module compatibility (third-party transceivers often break between versions).

Skipping updates on this unit is not an option if you rely on 802.3af/at power delivery or VLAN segmentation.

3. FIXED ISSUES

• [BugFix] Resolved an issue where the switch could become unresponsive to web UI management requests after 45 days of continuous uptime (Memory Leak).
• [BugFix] Fixed a PoE negotiation failure with specific legacy IP cameras (802.3af class 2).
• [BugFix] Corrected SFP link flapping on Port 51/52 when using certain 10G DAC cables.

Update process:

Step 1 – Copy firmware to switch

copy tftp flash <tftp-server-ip> K_16_12_0005.swi primary

Step 2 – Verify image integrity

show flash

Step 3 – Set as boot image

boot system flash primary

Step 4 – Save config and reload

write memory
reload

Step 5 – Post-update check

show version
show running-config

3. Keep a Rollback Plan

Save the previous JL381A firmware file. To downgrade, use:

copy tftp flash <server_ip> old_firmware.swi secondary
boot system secondary

Error 4: Flash write fails at 50%

• Cause: Bad sector in SPI flash (common on cheap Puya chips).
• Fix: Replace the flash chip entirely (desolder, solder a new Winbond 25Q32).

Step-by-Step Firmware Upgrade (Web GUI & TFTP)

Upgrading the JL381A is low-risk if you follow the "Primary/Secondary" partition strategy.

4. Interoperability

If you have mixed networking gear (e.g., JL381A with Cisco, UniFi, or older HP switches), firmware updates ensure the spanning tree protocol (STP) and link aggregation (LACP) work harmoniously.

Final Verdict: What Firmware Should You Run Right Now?

• If your JL381A is in production: Download 16.11.0012 (or the latest 16.11.x patch). Test it in a maintenance window.
• If you are deploying a brand new JL381A: Downgrade to 16.11.xxxx. Never ship the factory firmware (usually 16.08 or 16.09) to a secure site.
• If you need REST API v2 scripting: Suffer the bugs and go to 16.12.xxxx, but keep a cold spare ready.
