5.4.12 Replacing a T/H Sensor
Prerequisites
Recommended tools: Phillips screwdriver, flat-head screwdriver
The T/H sensor needs to be replaced.
A spare T/H sensor of the same model is available and functional.
Context
The T/H sensors are configured based on site requirements. The installation positions are as
follows:
For the hot-aisle containment, configure one T/H sensor for each IT cabinet, Converged
Cabinet, and battery cabinet.
For the cold-aisle containment, outside the aisle, configure two T/H sensors on the top of
the Converged Cabinet; inside the aisle, configure one T/H sensor on the air inlet of each
IT cabinet, network cabinet, and battery cabinet. A maximum of nine T/H sensors can be
configured for one module.
When a T/H sensor is installed inside the aisle, its installation position is on the beam of
the side panel of the front cabinet door (air inlet).
When a T/H sensor is installed outside the aisle, its installation position is on the top of
the Converged Cabinet.
T/H sensors can be replaced in the same way. This section describes how to replace a T/H
sensor that is installed near the front door of the cabinet.
