HPE 1920-8G-PoE+ (180W) (JG922A)
HPE (Hewlett Packard Enterprise) OfficeConnect 1920 Series Switch.
The 1920 series features a variable number of gigabit (1000BASE-T / IEEE 802.3ab) ports, as well as a smaller number of 1 Gbit/s SFP ports.
The JG922A variant features 8 1000BASE-T ports, and 2 SFP ports. It is has two 40mm fans, and has an integral AC supply (100 - 240V AC 50/60Hz 3.3A nominal). There is a console port which uses the H3C/Cisco pinout to provide RS232 on an 8P8C (RJ45) connector.
The 1920 series all use single core 500 MHz MIPS-4KEc Realtek RTL83xx SoCs, have 32 MB of flash, and 128 MB of RAM.
All 1920 series switches are designed to occupy “1U” (1.75“ / 44.5mm) in a standard 19” equipment rack. All models have rack mount options, but the 8 port models have smaller (under 19“ wide) enclosures which may be useful for non-rack usage.
General info about OpenWRT on Realtek switch SoCs can be found on the wiki that OpenWRT developer Sander Vanheule maintains.
break the generic 1920 series info out in to a separate page, since so much info is shared between all models in this series.
Design Origins and Alternative Brandings
The software and hardware design of these switches appears to originate from 3Com (which was acquired by HP in 2010), rather than the “HP ProCurve” line of switches which run HP's own in-house embedded OS rather than Linux. The design and manufacturing was carried out by H3C (which was wholly owned by HP during this time, but was later sold off).
Older examples of these switches were manufactured before Hewlett Packard split into “consumer” and “enterprise” divisions. These carried the branding “HP 1920-8G-PoE+ (180W) Switch” and the same JG922A model number.
H3C also sold these switches under their own brand as the H3C S5110 switch series, with the S5110-28P-SI assumed to be equivalent to the JG924A.

Hardware Highlights
Installation
→ Install OpenWrt (generic explanation)
Before installing OpenWrt, you may wish to install the latest OEM firmware (at time of writing CMW520-R1120) in order to ensure you are running the latest bootloader version. You can either do-so via the OEM software web interface, or using the tftp method as outlined below.
Installation is currently via TFTP.
- Configure a tftp server on a computer which is reachable from the switch via Ethernet. Note the IPv4 of the tftp server.
- Download the “initramfs-kernel” image from the download link below (either current or stable), rename it with a file name of 50 characters or less e.g.
host(the default), and make it available to the tftp server. - Connect to the serial port on the front of the switch using an 8P8C RS232 adapter.
- Power on the switch.
- Allow the switch to begin booting its second stage bootloader.
- When prompted
Press Ctrl+B to enter extended boot menu..., do-so. - Select menu item 3
Enter Ethernet SubMenu. - In the
Ethernet SubMenu, select item 5Modify Ethernet Parameter. - When prompted
Protocol (FTP or TFTP), entertftp. - When prompted
Load File Nameenter the name you chose above. - When prompted
Target File Nameleave it unchanged (value is not used). - When prompted
Server IP Addressenter the IPv4 address of the tftp server. (default is 192.168.0.11) - When prompted
Local IP Addressenter a spare unused IPv4 address which is accessible from the tftp server (e.g. an unused IP address on the local subnet) (default is 192.168.0.123). - When prompted
Gateway IP Addressenter a value if the Local and tftp Servers are on different subnets, otherwise leave at the default. - Back at the
Ethernet SubMenu, select item1-Download Application Program To SDRAM And Run.
OpenWRT will now boot from RAM (it is not yet on flash). At this point you may wish to backup the existing factory firmware and configuration - either by following the create_full_mtd_backup instructions, or by downloading a copy of every mtd partition via the LuCI web interface (e.g. at http://192.168.1.1/cgi-bin/luci/admin/system/flash ).
Of note is no DHCP server on the switch, unlinke routers, at least on the build 23.05.4 so go for static IP in the 192.168.1.0/24 range.
Once that is done, you can download and install the sysupgrade package to overwrite the factory firmware install, then you will need to follow the instructions in the Initial installation: section of the git commit message to configure the bootloader to automatically run OpenWrt.

OEM easy installation
The instructions below are for Broadcom devices and only serve as an example.
Remove / modify them if they do not apply to this particular device!
This section deals with
- How you install OpenWrt from a device freshly opened
- The steps required such as reset to factory defaults if the device has already been configured
Note: Reset router to factory defaults if it has been previously configured.
- Browse to
http://192.168.1.1/Upgrade.asp - Upload .bin file to router
- Wait for it to reboot
- Telnet to 192.168.1.1 and set a root password, or browse to
http://192.168.1.1if LuCI is installed.

Upgrading OpenWrt
These are generic instructions. Update with your router's specifics.
LuCI Web Upgrade Process
- Browse to
http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/LuCI Upgrade URL - Upload image file for sysupgrade to LuCI
- Wait for reboot
Terminal Upgrade Process
If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:
sysupgrademtd
Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
sysupgrade
- Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
mtd
If sysupgrade does not support this router, use mtd.
- Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot
Debricking
Failsafe mode
Basic configuration
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
Specific Configuration
Please fill in real values for this device, then remove the EXAMPLEs
Network interfaces
The default network configuration is:
| Interface Name | Description | Default configuration |
|---|---|---|
| br-lan | EXAMPLE LAN & WiFi | EXAMPLE 192.168.1.1/24 |
| vlan0 (eth0.0) | EXAMPLE LAN ports (1 to 4) | EXAMPLE None |
| vlan1 (eth0.1) | EXAMPLE WAN port | EXAMPLE DHCP |
| wl0 | EXAMPLE WiFi | EXAMPLE Disabled |
Switch Ports (for VLANs)
Please fill in real values for this device, then remove the EXAMPLEs
Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.
| Port | Switch port |
|---|---|
| Internet (WAN) | EXAMPLE 4 |
| LAN 1 | EXAMPLE 3 |
| LAN 2 | EXAMPLE 2 |
| LAN 3 | EXAMPLE 1 |
| LAN 4 | EXAMPLE 0 |
Buttons

Fan failure is indicated by GPIO457. If it's low that means one of the two fans or both has failed. Future work could be moving to gpio-fan hwmon devices in device tree.
The PoE ID's are backwards to the port numbers if you're going to use realtek-poe As of time of writing the PoE LED's don't light but PoE itself works. Factory PoE had 190W PoE limit:
