Description

The PWR-1.6KW-DC is a 1.6 kW DC-input power module for the Cisco ASR 9900 fixed-chassis compact routers, such as the ASR 9903. It suits service provider and telecom sites that run on -48 VDC power and need to keep ASR 9900 aggregation and edge routers powered from a DC plant.

This variant takes a -48 VDC input and is the DC counterpart to the PWR-1.6KW-AC. Each module is rated at 1.6 kW, and an ASR 9903 chassis accepts up to four modules. With DC modules fitted, the chassis supports 2+2 power redundancy. AC and DC modules cannot be mixed in the same chassis, so a DC system should use DC modules only.

The ASR 9903 is supported from IOS XR 7.1.25, and the chassis operates at 5 to 40 C with front-to-back airflow. The AC alternative for the same chassis family is the PWR-1.6KW-AC.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: What input voltage does the PWR-1.6KW-DC use?
A: It is a DC module with a -48 VDC input, which is the standard supply in telecom and service provider facilities.

Q: How many power modules does an ASR 9903 take?
A: The ASR 9903 chassis supports up to four 1.6 kW power modules. With DC modules this gives 2+2 redundancy.

Q: Can I mix AC and DC power modules in the same chassis?
A: No. Mixing AC and DC power modules is not supported, so all modules in a chassis must be the same type.

Q: How does this differ from the PWR-1.6KW-AC?
A: The PWR-1.6KW-DC takes a -48 VDC input, while the PWR-1.6KW-AC runs from AC mains. Both are 1.6 kW modules for the ASR 9900 fixed chassis.

Q: Which chassis is this power supply used in?
A: It is a power supply option for the ASR 9900 compact fixed-chassis routers, including the ASR 9903, which is supported from IOS XR 7.1.25.
