J2300 Power System

The J2300 Services Router uses either AC or DC power. The autosensing power
supply (see Figure 2 or Figure 3) distributes the different output voltages to
the router components according to their voltage requirements.
The power supply is fixed in the chassis and is not field-replaceable. An AC power
supply has a single AC appliance inlet that requires a dedicated AC power feed. The
DC power supply has a terminal block that provides a single DC input (–48 VDC
and return) requiring a dedicated 15 A (–48 VDC) circuit breaker.
For information about site power preparations, see "Power Guidelines,
Requirements, and Specifications" on page 89. For information about connecting
the router to power and ground, see "Connecting Power" on page 102.

J2300 Cooling System

The cooling system includes a fan on the rear of the Routing Engine's
processor and a fan on the power supply.
The airflow produced by these fans keeps router components within the acceptable
temperature range (see Figure 6). The speed of the fan at the rear of the processor
is adjusted automatically according to current temperature.
