Overview
The DC2400 DC-input and DC-output power module provides a
maximum output of 2400 W. The available model is NSQM1DC2400.
It has the following features:
•It has protection against undervoltage input, overvoltage input,
overvoltage output, output short circuit, overcurrent output, and
overtemperature.
•It is hot swappable. You can install and remove the power
module on an operating device.
•It can operate in N+1 or N+N redundancy. For more information,
see "Power module configuration."
NOTE:
The power module shuts down automatically when its
temperature exceeds the acceptable range. When the
temperature returns to the acceptable range, the power module
restarts automatically.

Power module configuration
Follow these guidelines to configure power modules for a device:
•Determine the required number of power modules based on the
actual power consumption, the power module slot number, and
power redundancy design.
•Determine the power module redundancy design based on the
power source conditions.
{When two mains power inputs are provided, you can
configure the power modules in N+N redundancy. N+N must
be not greater than the total number of power module slots.
{When one mains power input is provided, you can configure
the power modules in N+1 or N+N redundancy. N+1 or N+N
must be not greater than the total number of power module
slots.
•For easy usage and maintenance, configure a circuit breaker for
each power input. The rated current of the circuit breaker must
be greater than 80 A.

Installing and removing the power
module
CAUTION:
Do not install the DC2400 power module and other types of
power modules on the same device.
The power module slots are either vertically or horizontally oriented,
depending on the device model. The power module installation and
removal procedure is similar for vertical and horizontal power module
slots. The figures in this section are for illustration only.
Installing the power module
To avoid bodily injury and device damage, follow the procedure
in Figure 2 to install the power module.
