Section 4 - Power Input Module Information
4. Power Input Module Information
The Power Input Module (PIM) is a half-height module that connects the power
source to the power supply. Install the Power Input Module behind the power
supply (in a rack mount or a panel mount rack) or above the power supply (in a
bulkhead rack). For example, if you install the power supply in the upper slot then
you must install its Power Input Module in the upper slot. Removal or insertion of
a Power Input Module will not disrupt operation of the 3500 rack as long as the
other power supply and its associated Power Input Module are installed.
4.1 AC Power Input Module (Low Voltage Version)
Use the low voltage AC Power Input Module, shown in Figure 4-1, when you will
use low voltage ac (85 to 132 Vac rms) to power the rack.
DANGER
Failure to properly ground the rack chassis may result
in high voltages on exposed surfaces of the 3500 rack.
High voltages can result in shock, burns, or death.
Always connect the metal rack chassis grounding
strap as shown in Figure 4-1 to avoid shock hazard.
