myRoom LMR-EO Network

369872c 1 05.21.18

Installation Overview

The network architecture that forms the Local Area

Network (LAN) for the myRoom processor and

server communications of the myRoom guestroom

control system can be adapted to an existing hotel's

network infrastructure. While this can be of

substantial savings in time and material when

adapted to a hotel's network infrastructure, the

responsibility, setup, and authority for that network

falls directly under that hotel's IT administration.

When using a hotel's network infrastructure, the

myRoom LAN must have unrestricted

communication within that hotel's IT parameters.

This document lists the myRoom LAN

IT requirements and must to be given to the hotel's

IT administration prior to system installation.

Timeliness of a project where myRoom is residing

on the hotel's network is dependent on that hotel's

IT planning and cooperation. The earlier the hotel IT

administration is brought into the project the easier

and more efﬁcient the installation will be.

Ethernet Overview

The myRoom guestroom management system

requires an IEEE 802.3 Ethernet link to enable

communications between myRoom processors as

well as between myRoom processors and the

myRoom server. When this Ethernet link is supplied

by a customer’s IT department, it must be designed

and conﬁgured to meet the hotel’s IT requirements

and the myRoom LAN requirements.

myRoom Ethernet Network Conﬁguration

System Overview

Each facility will have its own characteristics. This

document outlines the guidelines and requirements for

the infrastructure to support the Lutron myRoom

system.

The myRoom Ethernet communications link follows

the IEEE 802.3 Ethernet standard using a minimum

cabling of Category 5 (CAT5). This copper or ﬁber

wiring must follow the standard IEEE 802.3 Ethernet

wiring rules for distance and separation.

•CAT5maximumdistancerequirement:

328 ft (100 m).

•Ifacablerunoflongerthan328ft(100m)isrequired,

an Ethernet switch (by others) will need to be used to

extend the length.

It is possible to use an existing Ethernet infrastructure

installed in the building as the myRoom processor

communications link. When this is done, the

customer, network installer, and network administrator

must be aware of the myRoom system requirements.

The myRoom system uses IP any-source multicast

between the myRoom server and processors by

default. The customer-provided network must be

conﬁgured to allow multicast trafﬁc between the

myRoom server and processors on the network.

The myRoom VLAN must be separate from the rest of

the hotel's network systems. This includes the guest

room network, point of sale systems and any public

access networks.

System Start-Up

When the network is supplied by others, the

network must be operational before the certiﬁed

Lutron service engineer arrives on-site for system

start-up. The system start-up cannot be completed

without reliable connectivity between the myRoom

processors and the myRoom server.

The customer may be required to schedule an

additional ﬁeld service visit at an additional charge if

start-up cannot be completed. This may occur if the

network is not installed or if any networking

equipment required to ensure connectivity between

myRoom components is not operational and

properly conﬁgured.

Site and Network Access

Certiﬁed Lutron service engineers and supporting

personnel must have access to network equipment

required to ensure communication between Lutron

components on the network.

If access to network equipment and/or use of

network analysis tools is not permitted, the

customer must ensure that qualiﬁed network

support personnel are on-site and available to

support the certiﬁed Lutron service engineer during

the commissioning process. Lack of support may

require scheduling additional ﬁeld service visits at an

additional charge.

Network Documentation

The network conﬁguration settings of the Lutron

equipment connected to the network; such as, IP

addresses, subnet masks, and gateway addresses,

must be supplied to Lutron prior to the certiﬁed

Lutron service engineer’s arrival on site to

commission the system.

Note: The server and each processor will need its

own unique IP address for the system VLAN.

Network Support Disclaimer

When the network is supplied by the customer’s IT

department, Lutron cannot be held responsible for

myRoom system downtime that results from network

downtime.

The network that is used to communicate between

Lutron myRoom equipment is utilized as a control and

a data network. Control networks require more

predictable and consistent response times. Increased

trafﬁc from corporate intranet data can greatly affect

these response times.

Network reliability impacts the collection of data from

the myRoom system. This data is used to generate

reports and to assess system performance. Network

reliability also impacts control functions.

Lutron recommends that the customer employ

qualiﬁed network support personnel that will maintain

the reliability and performance of the network post-

occupancy.

Network Equipment Requirements

All network equipment ports connected to the Lutron

myRoom processor are conﬁgured to

10 / 100 Mbps data speeds.

Network communications between the myRoom

processor and the Lutron server must not rely on

wireless technology. A wired IEEE 802.3 Ethernet

network is required for the myRoom system to

function.

The myRoom management software uses a browser

based user interface that can be used with wireless

technology, IEEE 802.11 in communications to the

myRoom server.

Physical and administrative access to network

equipment should be limited to authorized personnel

only.

IP Multicast Conﬁguration

Lutron uses IP any-source multicast for system

communication between myRoom processors and

the myRoom server.

Each guestroom in the myRoom system must have

its own unique multicast address. These multicast

addresses are assigned to Lutron for use with the

myRoom system only. These multicast addresses

must be determined and conﬁgured prior to the

certiﬁed Lutron service engineer’s arrival on-site to

commission the system.

Each assigned multicast address must have the

ability to reach its assigned myRoom processor on

the system. Every myRoom processor on the

system will communicate to the myRoom server

using multicast and unicast.

IGMP (Internet Group Management Protocol)

In order to properly route multicast trafﬁc between

Layer 2 and Layer 3 devices, "IGMP snooping"

needs to be enabled on all switches in both

directions from the myRoom server to the myRoom

processor and from the myRoom processor to the

myRoom server.

The myRoom system multicast supports the IGMP

standard versions 1, 2, and 3.

PIM (Protocol Independent Multicast)

If routing multicast trafﬁc between Layer 3 devices

over a LAN or WAN, Protocol Independent Multicast

will need to be enabled to properly route the multicast

trafc.Bothsparsemodeanddensemodeare

supported.
