Ethernet Network Installation
The following sections describe the recommended cable lengths and how to terminate
the cables at each face plate/wall jack.
• Topology
• Cable Runs
• Workstations, IP Printers, KDS Controller, and OCC
• LAN Cable Termination
• Extending Ethernet Beyond the 90 Meter Limit with Fiber Optic Cable
Topology
A twisted-pair Ethernet LAN is based on the distributed star or tree wiring topology
where the network switch or router is the central element.
Cable Runs
Before cable is pulled, determine the physical location of all devices including the
workstations, servers, wireless access points, IP Printers, RDU, and OCC. Specify the
equipment location in the floor plan or riser diagram of the property.
Workstations, IP Printers, KDS Controller, and OCC
Ensure all horizontal cable runs from the patch panel/switch/router(s) to individual
work area faceplates are at least 3 meters (10 feet) to no more than 90 meters (295
feet). The 3 meter minimum allows collisions to be more easily detected.
Limiting the cable run to 90 meters reserves 10 meters (33 ft.) for patch cables at the
patch panel and the device.
Ensure all faceplates, modular connectors, patch panels and patch cords are the same
category as the selected cable. In other words, when you pull Category 6 cable,
ensure all other components are rated for Category 6 as well. If you are installing
shielded cable, all other components including the patch panel must provide a location
to terminate the ground wire.
LAN Cable Termination
Several methods are available for terminating the horizontal cable runs. Oracle
MICROS recommends the 110 Connect system by AMP or other suppliers. This
system uses the reliable 110 style punch-down RJ45 modular jack and are available in
both shielded and non-shielded versions.
A second termination method is based on the 8-pin RJ45 modular “keystone”
insulation displacement connector, similar to those available for MICROS IDN devices.
