Established Global IT Distributor
With over a decade of industry experience, we are a certified Cisco Partner delivering genuine enterprise networking hardware and trusted services to system integrators, ISPs, and enterprises worldwide.
DS-CAC97-3KW Description
The DS-CAC97-3KW is the Cisco MDS 9700 3000W AC power supply, the AC unit that fills the power bays of the MDS 9700 Series Multilayer Directors and the part number that appears in the ordering tables of the MDS 9706, MDS 9710 and MDS 9718 data sheets alike as a common MDS 9700 Series component. On an MDS 9710 the chassis presents 8 power supply bays and the platform provides hot-swappable 2N redundant power, so units are added and replaced against a live director rather than during a chassis outage. The supply measures 22.04 x 3.95 x 1.6 in. (55.98 x 10.03 x 4.06 cm) and weighs 6 lb (2.7 kg), and its DC counterpart DS-CDC97-3KW carries the same 3000W rating in a physically longer 23.54 in. body, which is the visible difference between the two beyond the input type. How many of these units a chassis needs follows the port load rather than a fixed rule: Cisco publishes typical MDS 9710 consumption with three fabrics at 2695 W for 192 ports, 3655 W for 288 ports and 4615 W for 384 ports, and the pre-configured DS-C9710-V2K9 and DS-C9710-V3K9 bundles ship with four and six of these supplies respectively out of the eight bays available.

Application Scenarios
Installed in the power supply bays of MDS 9700 Series directors as the AC-fed unit supporting the platform hot-swappable 2N redundant power design.
Swapped into a director carrying production storage traffic, since the platform supports hot-swappable power without taking the chassis out of service.
Deployed in facilities running AC distribution within the 0 to 40 degrees C ambient envelope the MDS 9710 chassis specifies.
Related Ordering Boundary
Input Type Splits The Two Three Kilowatt Units
DS-CAC97-3KW is the AC unit and DS-CDC97-3KW the DC unit at the same 3000W rating; the AC body measures 22.04 in. deep against 23.54 in. on the DC version, so the two are not interchangeable on a facility feed and the input type has to be settled before the order rather than at install.
Bundle Configurations Already Include Some Units
DS-C9710-V2K9 ships with four of these supplies and DS-C9710-V3K9 with six, both against an eight bay chassis; ordering this PID alongside either bundle adds to that count rather than enabling power, and only the bare DS-C9710 chassis arrives with no supplies at all.
Unit Count Follows Port Load Rather Than A Fixed Rule
Cisco publishes MDS 9710 typical consumption with three fabrics at 2695 W for 192 ports, 3655 W for 288 ports and 4615 W for 384 ports rather than a required supply count, so the number of 3 kW units a chassis needs is derived from the planned port population and the chosen redundancy mode.
Selection Guide
1. The Bay Count Is Not The Order Quantity
An MDS 9710 has eight power supply bays but the platform is built for hot-swappable 2N redundancy, so the order quantity comes from doubling the units needed to carry the planned load rather than from filling every bay; a lightly populated director does not need eight supplies to be redundant.
2. Where The DC Unit Belongs Instead
A facility distributing DC power takes DS-CDC97-3KW at the same 3000W rating rather than this AC unit, and the DC body is 1.5 in. longer, so a rack sized tightly at the rear for the AC unit gains 1.5 in. of required clearance the moment the input type changes.
3. One Part Number Across Three Chassis Sizes
Because this supply appears in the MDS 9706, MDS 9710 and MDS 9718 ordering tables as a shared MDS 9700 Series component, a mixed estate of director sizes carries one AC power spare rather than one per chassis model, which simplifies the spares pool.
4. Growth Beyond The Bundled Supplies
The pre-configured DS-C9710-V2K9 and DS-C9710-V3K9 bundles leave four and two bays free respectively, so adding line cards later draws on this PID as a separate order line once the port load moves past what the shipped supplies carry.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Facility input type |
Confirm the rack feed is AC rather than DC. |
DS-CDC97-3KW is the DC unit at the same rating and the two are not interchangeable on a given feed. |
|
Existing supplies in the chassis |
Confirm how many bays are already populated, particularly on a chassis delivered as DS-C9710-V2K9 or DS-C9710-V3K9. |
Those configurations ship with four and six supplies respectively, so the additional quantity needed is smaller than the eight bay count suggests. |
|
Planned port population |
Confirm the port count the director will carry against the 2695 W, 3655 W and 4615 W typical figures for 192, 288 and 384 ports. |
The supply quantity follows the load rather than a fixed rule published per chassis. |
|
Redundancy mode |
Confirm whether the design runs 2N redundant power and size the unit count accordingly. |
The platform supports hot-swappable 2N redundancy, which doubles the units needed to carry a given load. |
|
Target chassis model |
Confirm the director is an MDS 9706, MDS 9710 or MDS 9718. |
The part number is listed as a shared MDS 9700 Series component across those three data sheets. |
|
Rear clearance |
Confirm the rack position accommodates the 22.04 in. body depth. |
The DC variant is longer at 23.54 in., so a later change of input type also changes the clearance requirement. |
