35InRow RC Installation Manual
Installing the rack temperature sensors
1. Insert the rack temperature sensor connector in the temperature sensor port at the user interface. See
“User interface connectors” on page 33.
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 user
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.
2. Route the sensor through either the top or the
bottom of the adjacent server rack.
3. Secure the temperature sensor cable to the front
door of the adjacent server rack at multiple
locations using the provided wire clips as shown.
NOTE: Remote rack sensors must be installed for proper operation.
The sensors must be installed where lack of sufficient cooling air is most likely. The optimum position of
the rack temperature sensors will vary from installation to installation. Servers most likely to have
insufficient or inadequately-cooled cooling air due to the recirculation of hot air from the hot aisle
include:
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.
