There are four network switches in room B.Z14, and one in room B.01, each providing 44 1000baseT ('Gigabit ethernet') ports. Ports on each of these switches can be configured onto any of the public or private VLANs available in the building. Each of these five switches has a 10Gbps uplink to the network core.
A port in one of the switches will be configured for your machine on installation. Switch ports are not interchangeable: you must not re-patch your machine to any other switch port. Please, never rearrange, add or remove any network connections.
