LifeSize Video Communications Systems Installation Guide 2

Preparing for Installation

As you prepare to install your LifeSize video communications system, consider the physical conditions of

the room, compatibility with displays and your network configuration and settings. Related documentation

is available from lifesize.com/support.

Before You Install

If you are not using DHCP, you might need guidance from your network administrator to complete the initial

configuration. You will need to manually set an IP address, subnet mask, and default gateway for your

LifeSize system.

Network Bandwidth

Poor audio and video quality might result from insufficient bandwidth on your network. LifeSize

recommends that your network be capable of at least 1 Mb/s (incoming and outgoing) for a high definition

video call. During video calls with lower bandwidths, LifeSize systems automatically select the best

resolution that can be achieved with the available bandwidth.

Domain Name Service Server

If you intend to use domain addresses for placing calls, either configure a DNS server or use a DHCP

server that automatically sets a DNS server.

Room Configuration

The size, shape, layout, and occupancy of the room dictate where you place your video conferencing

components. For example, in a multi-user conference room, place a LifeSize MicPod or LifeSize Phone at

the center of the group of participants.

All LifeSize codecs except LifeSize Room 220i can be locked with a secure loop to prevent physical

removal of the device. For assistance, contact your LifeSize Partner or LifeSize Customer Support.

WARNING Avoid routing cables from the codec across foot-traffic areas. Tripping on

the cables can cause personal injury as well as permanent damage to the

connectors in the cables and the codec itself.

The lighting in your environment affects image quality. The optimal lighting for LifeSize systems is 300 to

500 LUX. If light levels are set too low, consider adding artificial light. Indirect light from shaded sources or

reflected light from pale walls often produces excellent results. Avoid the following:

•direct sunlight on the subject matter, background, or camera lens

•direct illumination of the subject matter and camera lens

•colored lighting

•harsh side lighting or strong light from above

System Components

Your package contains the following components:

•LifeSize codec and power supply unit (PSU)

NOTE The LifeSize Room 220i does not feature a PSU. Instead, a power cord plugs

directly into the back of its chassis.

•Codec stand (LifeSize Room 220 and LifeSize Team 220 only)

•LifeSize remote control, including three AAA batteries

•Standard cable kit

You can substitute cables of longer lengths with the following limits:

-HDMI: 15 meters (49 feet)

-Ethernet: 100 meters (328 feet)

Read Cables for more information.

•Quick reference card (QRC)

•Documentation CD

Depending on the package that was purchased, one of the following audio components might also be

included:

•LifeSize Phone

•LifeSize MicPod (includes strain relief clip)

Similarly, your package might include the LifeSize Camera 10x, along with a power supply and standard 3

meter (9.8 foot) HDMI cable.

Rack Mounting Considerations

You can mount LifeSize Room 220i without the use of rails. Before you install the system in a rack,

however, consider the following:

Consideration Description

Rack stability Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor when

the full weight of the rack rests on them. In a single rack installation, attach stabilizers to the

rack. In multiple rack installations, couple the racks together.

Airflow and access Leave approximately 75 centimeters (30 inches) of clearance behind the rack to allow for

sufficient airflow and ease in servicing.

Ambient operating

temperature

If you install the device in a closed or multi-unit rack assembly, the ambient operating

temperature of the rack environment might be greater than the ambient temperature of the

room. Consider installing the equipment in an environment that is compatible with the

manufacturer’s maximum rated ambient temperature.
