T1600 Three-Input 240-A DC Power Supply Description

Each three-input 240-A DC power supply weighs approximately 25 lb. (11.3 kg) and
consists of three inputs, three 80-A circuit breakers, a fan, and LEDs to monitor the status
of the power supply. Figure 36 on page 60 shows the three-input 240-A DC power supply.

T1600 Three-Input 240-A DC Power Supply Inputs

The three-input 240-A DC power supply inputs are labeled
from top to bottom. Each input consists of –48 VDC and return—each with its own 80-A
circuit breaker. The input mode switch on the faceplate allows you to set the DC power
supply to either or

T1600 Three-Input 240-A DC Power Supply Load Sharing and Fault Tolerance
When the T1600 router is operating normally and both power supplies are switched on,
load sharing between them occurs automatically. When one power supply fails or is
turned off, the other power supply immediately assumes the entire electrical load for
the system. A single power supply can provide full power for as long as the router is
mode. mode is required for the T1600 Core
