Ideas about moving the rack two floors down to the basement

Leave a Comment / hardware, racks, Unifi / By /

This is a work in progress. As I make more decisions and receive additional suggestions/advice, I will update this page. I live in an apartment. The Verizon FiOS ONT is outside on the ground floor. I live two floors up. I am considering moving the rack from the bedroom to 7x12ft locked room in the basement. It would share space with my washer and dryer (which is vented to the outside). Why? noise […]

Disconnect UNIFI switch – US-16-XG

1 Comment / hardware, Unifi / By /

My Unifi US-16-XG switch was offline. It was still functioning correctly, but it was not in contact with the Controller. I wasn’t sure how to fix this, but this blog post shows what I now think should always work. It consists of two steps: Get the switch talking to the Controller Make the above change permanent The key point to remember: the Controller is always the voice of authority when it comes to

UAP-AC-PRO: setting the management VLAN on a Unifi AP

Leave a Comment / hardware, Unifi / By /

I have two Unifi WAPs at home. I’ve installed them at three other locations. They are a great product. One problem I had was getting the management interface set. By that, I mean the IP address of the unit. I wanted it to be in a specific range, and therefore it had to be in a specific VLAN. However, I wanted the WIFI traffic to be in a different VLAN. It is not

Getting into the CLI for a Unifi switch

7 Comments / hardware, Unifi / By /

I’m writing this down so I can find it later. The management IP address on my Unifi US-16-XG is wrong. I’m going to change it via a combination of the controller and the CLI. Let’s hope this works. Hope? Why hope? Unifi switches are designed to be managed via the webgui (i.e. their controller). I’m sure this will also work on my US-48 switch too. Get connected and get in I’ve done this

I’ve been given a Dell PowerEdge 710. I’ve installed two 30GB SSDs, installed FreeBSD 11 on them, and added four 500 GB SSDs. It will become a tape library server, replacing the R610 which will no longer be used. Some of the hardware came from the R610. The zpools: The filesystems: And dmesg:

Moving boot from one zpool to another

Leave a Comment / beadm, Disks, FreeBSD, Open Source, ZFS / By /

I’ve been having boot issues with a server containing 20 HDD, all behind HBAs. I have decided to start booting off SSDs. In that previous blog post, there was much speculation about where to mount the new drives, etc. In the meantime, I came up with a solution which did not involve magnets and used a pair of INTEL 730 SSDs I had in another chassis. Let’s start with how I configured those
