ESI Communications Servers Sales Overview

Power consumption

The following table shows the power consumption of each ESI Communications Server when fully loaded:

System Cabinets (Base and Expansion) Power consumption (watts)

ESI-1000 6 1,080

ESI-600 4 720

ESI-200 2 360

ESI-100 2 125

ESI-50, ESI-50L 2 72

ESI-1000, ESI-600, and ESI-200

For the ESI-1000, ESI-600, or ESI-200, each Base Cabinet or Expansion Cabinet is powered by its own separately

fused power transformer. For rack-mounted systems, a power shelf is available onto which all power transformers may be

mounted so only one power cable is required for connection to a commercial AC power outlet or UPS system.

Since each cabinet has its own distributed power, the heat dissipation of each power “brick” is well within the environmental

range for proper operation of all system components. In an installation environment with insufficient space surrounding

the system and mounting rack, the power shelf may be mounted at the top of the rack (above the Base Cabinet) so that

the power bricks can utilize convection cooling as a means of dissipating any potential build-up of heat.

ESI-100, ESI-50, and ESI-50L

For the ESI-100, ESI-50, and ESI-50L, each Base Cabinet shares a 24-VAC power supply “brick” (five-amp on the ESI-100,

and three-amp on the ESI-50 and ESI-50L) with an Expansion Cabinet which is installed upon the Base Cabinet.

Typically, the connected cabinets will be wall-mounted, which should allow sufficient space to allow venting of heat from

the power supply.

Special software requirements

Flexible numbering and compatibility with the optional VIP Softphone and VIP ACD (Supervisor/Agent) applications are

available with the following system software:

• ESI-1000, ESI-200, ESI-100, ESI-50, and ESI-50L

— All versions.

• ESI-600 — Version 16.1.0 (and higher).

Environmental considerations

Common sense should dictate where an ESI Communications Server is installed: a dry, clean and accessible area.

Every ESI Communications Server is tolerant of broad ranges in environmental characteristics:

• The ambient room temperature should fall within the range of 40°–80° F.

• The relative humidity in the room should not exceed 90%.

If the equipment is to be rack-mounted, ensure that there is adequate room for a standard 19-inch rack. If wall mounting

is planned, ensure that all power cords have ready availability to a 110 VAC power outlet. For optimum performance,

ensure that the system is located no further than 1,000 feet from the farthest station location.

FCC regulatory information

Each ESI Communications Server model has been tested and found to comply with the limits for a Class A digital

device, pursuant to Part 15 and Part 68 of the FCC Rules. These limits are designed to provide reasonable protection

against harmful interference when the system is operated in a commercial environment. The FCC number for all ESI

Communications Servers is 1T1MF08B33727, with a ringer equivalency of 0.8.

ESI Communications Servers and all associated ESI telephone station equipment meet all FCC requirements for

hearing-aid compatibility.

The ESI-50L is incompatible with both VIP Softphone and VIP ACD. It may be upgraded to an ESI-50, which supports both applications.
