For some time I simply used unmanaged gigabit switches to extend my network.
This worked without a problem for a long time.
However, more recently I was looking into the possibility of adding VLANs to my network, something unmanaged switches do not support.
Additionally, each of my HPMicroservers have two gigabit NICs and both FreeNAS and Proxmox support link aggregation, something I wanted to implement.
Again, this is not possible with unmanaged switches.
I spent some time looking at the options available.
The Cisco SG300 was a very strong contender but at the time it was a little more expensive than I would have liked.
While the v1910-24G is technically a Layer 2+ “smart” switch and not a true Layer 3 “managed” device, it supports vlans and static routes which is all I actually required.
Making it quiet
I was very happy with my new purchase, that is until I powered it up.
Being a 1U rackmount device, the v1910-24G is equipped with a single 40mm fan which is extremely loud to say the least.
In fact at approximately 38dB, the noise it created easily drowned out everything else in my lab combined.
(NB: The 5v part is crucial as the power provided to the fan by the switch is not enough to power a 12v fan.)
It was a very simple process to open the switch and replace the fan using the scotchlok kindly included by Noctua.
To avoid the “FAN_FAILED” and “FAN_RECOVERED” messages in the logs I connected the red and black power leads to the fan and connected the white PWM cable to the switch’s ground screw.
While certainly not silent this did massively improve the noise output of the switch.
Accessing the WebGUI
The switch came with a sticker detailing the default IP address of the device and I was simply able to log in with the username “admin” and no password.
HP are still producing firmware for the v1910-24G so the first thing I did was to download the latest firmware and install it via the web interface.
I then configured the management interface IP address and went through the initial setup wizard to configure the switch. All fairly straight forward.
I will go through further configuration of the switch in future posts.
While the Web GUI of the v1910-24G is not fantastic, it’s certainly functional and allows for everything I require from a switch.
I did however want to access the switch from the command line like the Cisco devices that I am more used to working with.
Accessing the Command Line
I was pleased to find that I was able to enable ssh on the switch.
However, after ssh’ing into the switch I was rather disappointed to find that I was rather limited to a very small selection of commands which didn’t really allow for any configuration.
Thanks to Fred’s blog post at https://glazenbakje.wordpress.com I was able to enable the full commandline mode by using the command _cmdline-mode on.
The password on all v1910’s is 512900.
When opening an ssh session to the v1910-24G I typically copy and paste the following:
This looks like the following:
The commands available in this mode are as follows:
Additionally the system-view command allows for further configuration and unlocks the following commands:
To summarise I was and am very happy with my new switch and would highly recommend the v1910-24G for a homelab scenario.
