Network

Overview

The network consists of a cable modem feeding an OpenWrt router/AP, which in turn uplinks to the mezzanine switch. From there, connections run to two loft patch panels: one Blue, one Grey. Each network drop in the space has a corresponding Blue and Grey jack; only some are wired through to the switch, and only some are currently used.

Blue and Grey cables are functionally identical. The colours reflect physical routing rather than logical separation.

Static Devices

Most fixed equipment uses static DHCP leases on the OpenWrt router. If you add a static IP address, give it a static DHCP lease on the openwrt router, even if the device doesn't use dhcp. These are the main devices:

Device	IP Address
OpenWrt router	192.168.0.1
Home Assistant	192.168.0.2
Lazzor	192.168.0.4
