Pre-Installation

Room preparation

During the design of the data center, consider ease of entry for the equipment, floor loading factors, and accessibility to piping and wiring. In addition, the room temperature and humidity combination should conform to the environmental operating envelope as defined in the following graphics.

Seal the room with a vapor barrier to minimize moisture infiltration. Polyethylene film is recommended for ceiling and wall applications. Apply rubber- or plastic-based paints to concrete walls and floors.

Insulate the room to minimize the influence of exterior heat loads. Reduce fresh air to the minimum required by local and national codes and regulations. Fresh air imposes extreme load variation on the cooling equipment from summer to winter and causes increased system operating costs.

Air distribution

The equipment distributes air in a back-to-front discharge pattern, removing hot air from a hot aisle and discharging cooled air into a cold aisle.

NOTE: The equipment is designed for free air discharge or for use with the Rack Air Containment System or Hot Aisle Containment System. The equipment is not intended to be connected to a duct system.

Rack temperature sensors

The rack temperature sensors control the equipment airflow and ensure adequate supply of cooling air to the server racks in the data center.

The equipment is supplied with three external rack temperature sensors. See “Install kit inventory” on page 10. These sensors, along with cable ties and wire clips, are included in the installation kit shipped with the equipment.

How to install the rack temperature sensors

1. Insert the rack temperature sensor connector in the temperature sensor port customer interface connections. See “Customer interface connections” on page 39.

a. For a top installation, push the rack temperature sensor through the wire channel located at the top of the equipment in the left hand side just above the customer interface connectors.
b. For a bottom installation, route the sensor through the wire clamps along the electrical panel and then push the sensor through the customer access hole in the bottom of the equipment.

1. Route the sensor through either the top or the bottom of the adjacent server rack.
2. Secure the temperature sensor cable to the front door of the adjacent server rack at multiple locations using the provided wire clips as shown. See "Install kit inventory" on page 10.

NOTE: Remote rack temperature sensors must be installed for proper operation.

The sensors should be located on racks that are adjacent to the cooling unit. The optimum position of the rack temperature sensors will vary from installation to installation but should be located in close proximity to fan-cooled IT equipment to ensure accurate readings.

Servers most likely to have insufficient or inadequately cooled air due to the recirculation of hot air from the hot aisle include the following:

a. Servers positioned at the top of a rack
b. Servers positioned at any height in the last rack at an open end of a row
c. Servers positioned behind flow-impairing obstacles such as building elements
d. Servers positioned in a bank of high-density racks
e. Servers positioned next to racks with Air Removal Units (ARU)
f. Servers positioned very far from the equipment
g. Servers positioned very close to the equipment

Water outlet temperature sensors

There are two water outlet temperature sensors, one for top connection and one for bottom connection. These sensors are wired to the main board on the electrical panel.

The unit is delivered with top connection as the default configuration, i.e., the wire with a green tie wrap is positioned in connector J23 (marked with green) on the main board. If the configuration is changed from top to bottom, switch the wire already positioned in the connector J23 with the wire labeled with a green and a white tie wrap. This wire is part of the wire harness inside the electrical panel.

Communication connections

A-Link connections: The A-Link bus connection allows communication between cooling units. Only one InRow RC unit needs to be defined through the display. The numbering of the other InRow RC units (up to a maximum of twelve) will take place automatically.

To enable the equipment to work as a group, link the units using the supplied cables or CAT-5 cables with RJ-45 connectors as shown. Terminators (120 Ohm, 1/4 W) must be inserted into the open A-Link ports at the first and last InRow RC unit.

The maximum wire length for the entire group may not exceed 1000 m (3,280 ft).
