Line-Card Chassis Six-Input DC Power Supplies Description

 

The six-input DC power supply is required for a line-card chassis (LCC) in the TXP-T1600-3D configuration, TXP-T4000-3D configuration, and TXP-Mixed-LCC-3D configuration.

Each six-input DC power supply weighs approximately 39.7 lb (18.0 kg) and consists of six inputs, two blowers, a front and side air filter, and LEDs to monitor the status of the power supply. Each power supply is cooled by its own internal cooling system. Figure 1 shows the six-input DC power supply.

The six-input DC power supply inputs are labeled INPUT 0, INPUT 1, INPUT 2, INPUT 3, INPUT 4, and INPUT 5, from top to bottom. Each 60 A input consists of –48 VDC and return.

Note

There are no circuit breakers or passive fuses in the router.
