Cisco ASR1004-PWR-DC Power Supply | ASR 1000 Series DC PSU UK

Cisco ASR1004-PWR-DC is a Power Supply for ASR 1004 routers. High-capacity DC PSU with hot-swappable design for enterprise and telecom networks. Go by the part number. Items like this are routinely identical to look at and specific in what they actually fit.

Choosing the right supply. Three things decide whether a power supply will do the job. The chassis it is specified for, because supplies are not interchangeable across generations even where the connector looks the same. The input, AC or DC, which has to match the rack. And the output rating, which has to cover the PoE budget as well as the switch itself. If you are fitting a second unit for redundancy, both should be the same model and the same airflow direction.

How we supply it. Supplied new where available, otherwise as tested stock with warranty, subject to availability. If you are unsure whether this is the right part, give us the model it is going into and we will confirm it. Quotes by the next working day.
