From Sequoia Fabrica

Our Internet drop is from Monkeybrains and lands in the mezzanine lounge. Monkeybrains generally reaches the rest of the Internet via SFMIX, Cogent, Wave, Hurricane Electric

This connects to a Mikrotik router, Aruba IAP-225 access point, and Home Assistant hub. Wifi networks are Sequoia Fabrica and Sequoia Fabrica 24.

The space was wired with Cat6/6a and Cat5e long ago and there's a much larger network closet in the storage room near the front bathroom which contains a managed Cisco POE switch, switch1.

Ansible for defining what runs on soil and nursery is on github.

There is a single flat IP network and broadcast domain for this modestly-sized space:

Security LAN[edit | edit source]

There are some security devices in use inside the space. Currently, this is just PoE IP cameras with no microphones attached.

This uses IP space (which is currently only reachable via Tailscale and Nursery)

Frigate is running at

Telephone Network[edit | edit source]

There are two red analog telephones in the space. These are driven by Grandstream HT801 ATAs to put them on the network.

An asterisk instance is running on nursery, to which the telephones are registered.

Currently, only calling between the telephones is supported. One uses extension "100" and the other is "101"
