Thermal Limits for Chassis Loading
The specified ambient operating temperature range for each module is listed in the
specifications area at the end of each section throughout this manual. The required
operating temperature range for all modules is from 0 to 50°C (32 to 122°F).
The cooling fans will maintain the operating temperature of all components below maximum
limits in a fully loaded chassis as long as the following conditions are maintained:
■
There is sufficient clearance in front of and behind the chassis for air circulation.
■
The front and back panels of a chassis are not blocked.
Powering Considerations
The CHP chassis requires at least one Power Supply module. An additional redundant
load-sharing Power Supply may be installed in for improved reliability. All outputs of the
Power Supply module(s) are connected using internal diodes or steering field effect
transistors (FETs) with another Power Supply module. The function of the diodes or steering

Install chassis from the bottom of
the rack toward the top of the
rack to prevent the rack from
toppling.
