PWR-60W-AC

PWR-60W-AC is a power supply module for Cisco equipment, rated at 60 W.

This is an AC part. Most carrier routing equipment expects minus 48 V DC, so an AC supply usually means the site has no DC plant, and the consequence is that there is no battery reserve behind the router unless a UPS provides it separately. That is a real availability difference rather than a technicality.

At 60 W, the figure to compare it against is not the chassis maximum but the configuration you actually intend to populate. Line cards vary enormously in draw, and a chassis specified for a light configuration will not power a full one. Over-provisioning power is also how redundancy is achieved: a chassis with two supplies either shares the load or runs one as standby, and which of those it does decides whether a single failure costs you anything.

Three questions worth answering before any router purchase, whatever the model. What the throughput requirement actually is with your feature set enabled, rather than the datasheet figure measured without it. Whether the features you need are licensed as well as present, since on most platforms security and performance are separate entitlements. And how many slots or ports you will need in three years, because adding capacity is cheap and replacing a chassis is not.

Tell us the chassis, what is already fitted and what you intend to populate it with, and we will confirm the supply is sized for it. On a replacement, read the part number off the unit in the chassis rather than working from the original order, because power modules are among the most commonly swapped parts in a router’s life.

Green Code Technologies is a supplier of Cisco, and we supply Huawei and Juniper networking alongside HPE, Dell, Samsung, Netgear, Ubiquiti and Asus. We would rather tell you a part is no longer supported, or that we need to check it, than take an order for something that will not do what you need.
