NOTE: Power cords and cables must not block access to the JRR200 route
reflector components or drape where people might trip on them.
CAUTION: The AC power cord for the JRR200 route reflector is intended for
use with the route reflector only and not for any other use.
JRR200 Route Reflector DC Power Supply
The JRR200 Route Reflector is shipped with two redundant DC power supply units
pre-installed in the rear panel of the chassis. The DC power supply unit is a
field-replaceable unit (FRU) and you can install it without powering off the JRR200 route
reflector or disrupting the route reflector function. If one power supply unit fails or is
removed, the other power supply unit redistributes the electrical load without interruption.
Each power supply unit is cooled by its own internal cooling system.
Each DC power supply unit weighs approximately 2.2 lb and has two independent pairs
of DC input lugs, a fan, and LEDs for monitoring the status of the power supply. It gives
an output of 650 W.
Figure 9 on page 26 shows the DC power supply unit.
Figure 9: DC Power Supply Unit
Each DC power supply unit faceplate contains three LEDs that indicate the status of the
power supplies.
Figure 10 on page 26 shows the location of the LEDs on a DC power
supply unit.

Table 12 on page 27 describes the DC power supply unit LEDs.
