First, I'm always willing to entertain the possibility that there is a hardware fault in the switch. But it's good to try and eliminate that possibility by diagnosis.
Ports shut down for a number of reasons.
1. PoE overcurrent. Are you drawing too much for the switch, either per-port or total?
2. Security. Is there MAC security on? That will shut down a port if a strange device is attached.
3. Spanning-Tree. If it detects a loop, it will shut down the port.

Use the interfaces to check the status of the 'down' port. Check the (CLI) logs in the switch for events. Put a PC on the console port and monitor the switch from reboot to fail for messages.

Customizable features include VLANs, Spanning Tree, Link aggregation trunking, and IGMP Snooping. All models include Rapid Spanning Tree Protocol (RSTP) and DSCP QoS policies.
These switches support flexible installation options, including mounting on walls, under tables or on desk tops.
Some models are of a fan-less design, making them quiet for office deployments.
Energy Efficiency and Lower TCO
The HPE 1820 Switch Series include the latest energy-savings capabilities, including Energy Efficient Ethernet (IEEE), idle-port power down and PoE Port Scheduler.
The 8-port Gigabit Ethernet model can be powered by an upstream PoE switch for environments where no line power is available.

Quality of Service (QoS)
The HPE 1820 Switch Series traffic prioritization provides time sensitive packets (like VoIP and video) with priority over other traffic based on DSCP or IEEE 802.1p classification. Packets are mapped to eight hardware queues for more effective throughput.
Broadcast control allows limiting of broadcast traffic rate, to reduce unwanted network broadcast traffic.
IEEE 802.11p/Q delivers data to devices based on the priority and type of traffic.

This how-to will go through the process of updating the firmware on an HP switch. To check your current version run #show version from the command line. You will need a TFTP server for this. You can download one from http://www.solarwinds.com/products/freetools/free_tftp_server.aspx. Once installed, disable your Firewall or allow TFTP, UDP port 69, through it.
9 Steps totalStep 1: Search for your switch on HP's Networking Lookup Tool
Go to https://h10145.www1.hpe.com/support/SupportLookUp.aspx and type in the switches model number, then select your switch and click “Show selected items”
Step 2: Next, click on “Software downloads”Step 3: Select the most recent version and download the firmware
If the current firmware version is substantially older than the most recent, review the information on the download page and the Release Notes to verify that you can update directly to the new version.
Step 4: Copy the .swi file from the downloaded firmware folder to your root TFTP folder. On Solarwinds it is located at C:TFTP-RootStep 5: Log into the switch and backup the current config
Before you update the firmware, backup the current config. Save any changes by running
#write memory
Then, copy the config to the TFTP server.
#copy startup-config tftp .cfg
Step 6: Enter the menu interface on the switch
The firmware can be downloaded from CLI, but this tutorial will cover the menu interface way of downloading it. You can enter the menu from the CLI by running:
#menu
Step 7: Select the option Download OS from the menu![]() Step 8: Fill in the information about the file transfer and select 'eXecute'
First, make sure the Method is set to “TFTP” and change the TFTP Server to the IP address of your computer. Then, change the Remote File Name to the name of the .swi file on the TFTP server.
Step 9: Reboot and verify that the firmware has been updated
Cannot open .jpg files in windows 10. Once the firmware finishes installing, the switch will need to be rebooted for the changes to take effect. You can then verify it updated successfully by running:
#show version

Learning has never been so easy!
Whilst learning about updating our HP Pro-curve switches, I found many contradicting pieces of information on how to do this. This is my method for updating via the web interface (Focusing on a 2910-24G-PoE+ al Switch). Please bear in mind that not all of the HP pro-curve switches support the web interface. I'm going to assume you don't necessarily know the model of your switch, so i'll explain how to find it. Before any thing else, it is massively important to ensure that no-one will be disrupted whilst you are working on the switch. In my case, I was able to update our switches during the Christmas break period. Very few users were on site, so it was a good opportunity to do so.
11 Steps totalStep 1: Ensure you know correct IP address
The IP address is used to connect your machine to the switch to do the update. You should have a record of these IP addresses available to you.
Step 2: Find the model of the switch you are updating
It is important to ensure you know the model of your switch, as the software is different for each model. I've placed the IP address of my switch into an internet browser (Note: some older HP switches require java support in browser), and you can see the model is a 2910-24G-PoE+ al Switch (J9146A)
Step 3: Obtain copy of new software from HP
Using the 'HP networking support tool', find the appropriate switch's links. Navigate to the software downloads page.
Step 4: Navigate to the software downloads page
Upon the page loading, you should find all of the available software for your switch. Ensure you know which version you are currently on (can be found via the web interface), and find the latest version. Also, it's always beneficial to read the release notes, both to check compatibility and to find which new features have been added/which bugs have been fixed.
Step 5: Download software
Once you've found the version you require, click on the marked button to continue to the download page.
Step 6: Open the web interface
Enter the IP address of your switch into a web browser. Log in with the 'manager' account and navigate to 'uploads/downloads' under the 'system' heading.
Step 7: Download configuration file
Important: HP always recommend backing up your switch's configuration file BEFORE updating software. Click on the listed configuration file and select download. This will download the configuration file to your local PC.
Step 8: Upload the software to the switch
Click on 'update' under the primary image. It will then ask you to choose a file. As default, the file for uploading uses the version of software as its title. In this case, W_15_14_0012.swi is the file required.
Step 9: Begin the upload/flash process
The switch will now prompt you to being the upload/flash. This may take a few minutes and the web interface should refresh when completed. DO NOT interrupt the power to the switch during this process, as it could easily cause irreparable damage to your hardware.
Step 10: Verify the switch has successfully written the new software
The page will re-load. The 'Primary' software image will now show the new version of software. The upload/flash was successful.
Step 11: Reboot the switch
Assuming that no one will be disrupted, reboot the switch from the web interface (using the link 'reboot'). Upon reboot, the switch will display the new software version on the home page. Check that all of your port configurations are still in place. If not, you can re-upload the configuration file (step 7, upload instead of download)
You've successfully updated you HP switch software. Remember, this guide only covers updating via the web interface and there are other methods of updating if this isn't suitable for you. The most common of these is via a TELNET session, which is covered in a 'how-to' by 'Gitclaus' found here: http://community.spiceworks.com/how_to/82205-how-to-update-hp-switch-firmware
