The local network infrastructure requirements for any networks where Orchard Macs are located are as follows.
- Per managed desktop Mac a dedicated 100MBit/sec (or faster) Ethernet port
- Static IP addresses for all managed desktop Macs allocated using DHCP
- Ethernet docking stations for managed laptop Macs are recommended for connection to shared storage and printers
- DNS including PTR records following the IT Services naming scheme for all managed desktop Macs
- NetBoot from the central Orchard servers (mmpboot1.nsms.ox.ac.uk & mmpboot2.nsms.ox.ac.uk) by enabling them as ip-helper-addresses/dhcp-relays
The following firewall exclusions are required.
- Allow SSH (tcp port 22) to all managed Macs from NSMS IP range (184.108.40.206/26)

- Allow bootps/bootpc (upd ports 67, 68) to all network segments containing managed Macs from NSMS NetBoot server (new-toy.orchard.ox.ac.uk)
For clients with more than 50 users we also recommend a network volume (shared using AFP or SMB reshared as AFP) with about 300GB free disk space to be used as a local software repository.
