Description

The PWR-CH1-950WDC is a hot-swappable -48V DC power supply module for the Cisco Catalyst C8500-20X6C edge platform in the Catalyst 8500 Series. It suits DC-powered deployments of the high-performance WAN and SD-WAN edge router, such as service-provider, data-centre, colocation and telco sites running a -48V power plant.

Each module is rated at 950W maximum output, with a DC input range of -40 to -72V and a 12V, 79A output. Nominal efficiency is 86%, and input current runs from 27.6 A to 15.3 A (23 A). Power connects through an Amphenol FXTH series 2-terminal block, with #10 wire rated for 30 A. It is the DC option alongside the 1100W AC PWR-CH1-1100WAC for the same chassis.

The 3RU C8500-20X6C has four power supply slots and needs at least two power supplies populated and powered, so a second or further module provides redundancy. All power supplies and fan modules in a chassis must use the same airflow direction. The power supply itself needs no licence.

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

FAQs

Q: Does this power supply need a licence?
A: No. The power supply itself needs no licence. The host Catalyst 8500 Series platforms initially require a Cisco DNA Advantage software subscription.

Q: Which chassis does the PWR-CH1-950WDC fit?
A: It is for the Catalyst C8500-20X6C. It is not for the C8500-12X or C8500-12X4QC, which use PWR-CH1-950WDCR and PWR-CH1-750WACR.

Q: How many power supplies does the chassis need?
A: The C8500-20X6C has four power supply slots and needs a minimum of two power supplies populated and powered. Additional modules provide redundancy.

Q: What power feed does it require?
A: A DC feed of -40 to -72V (-48V nominal), drawing 27.6 A to 15.3 A (23 A). It connects through a 2-terminal block with #10 wire rated for 30 A.

Q: How does it differ from the PWR-CH1-1100WAC?
A: The PWR-CH1-950WDC is a 950W DC unit running from a -48V supply. The PWR-CH1-1100WAC is the 1100W AC option for the same chassis.

Q: Can I mix airflow directions in one chassis?
A: No. All power supplies and fan modules in a chassis must use the same airflow direction, or an error and possible overheating will occur.
