A9KV2-DC-CBL-E Overview
A DC power cable is a power-distribution interconnect that carries direct current from a rectifier plant or DC distribution panel to networking equipment. In the service provider hierarchy, it sits between the facility DC power infrastructure and the router or satellite shelf power supply modules. DC powering is widely used in carrier and data center environments because it enables efficient power transmission, reduced energy conversion losses, and stable operation for high-availability networking gear.
Key characteristics of the A9KV2-DC-CBL-E include its purpose-built compatibility with the ASR 9000v-V2 Satellite Shelf (DC ETSI variant), an ETSI-standard connector interface, and genuine Cisco manufacturing that guarantees compatibility and warranty compliance. The cable is finished in black and is orderable both as A9KV2-DC-CBL-E and as the spares-orderable suffix A9KV2-DC-CBL-E=. Distributor listings place the part under UNSPSC code 26121636, and typical street pricing ranges from approximately $186.99 to $207.99 USD as of 2026-10-19.
Architecturally, the ASR 9000v-V2 satellite shelf extends the Cisco ASR 9000 Series aggregation router to remote locations, and the DC power cable is the mandated power-feed accessory for the DC/ETSI version of that shelf. Using third-party or generic cables risks connector mismatch and voids Cisco hardware warranty coverage, so Cisco specifies this exact MPN in the ASR 9000 satellite system installation documentation.
Typical applications include central offices, carrier hotel installations, and service provider data centers deploying ASR 9000v-V2 satellite shelves where -48V DC ETSI power plants are the standard. It is also used during rack integration and spare-parts stocking programs.
When installing, verify the DC plant polarity and breaker rating against the shelf installation guide, and follow Cisco torque and grounding requirements for the ETSI connector.

Typical Applications
A9KV2-DC-CBL-E is suitable for 6 applications: Service Provider Central Office DC Power Feed, Data Center ASR 9000 Satellite Deployment, Rack Integration and Factory Staging, Network Spare-Parts Stocking Programs, Mobile Backhaul and Remote Aggregation Sites, Cable Television and MSO Head-End DC Powering.
Service Provider Central Office DC Power Feed
Central offices run -48V DC plants as the standard power infrastructure, and the Cisco A9KV2-DC-CBL-E is the specified power-feed cable for connecting the ASR 9000v-V2 Satellite Shelf (DC ETSI) to that plant. The ETSI connector interfaces directly with the shelf power entry, while the cable lugs land on the DC distribution panel per ETSI positive-ground practice. Because satellite shelves extend ASR 9000 aggregation capacity to remote cabinets, a correctly gauged, genuine Cisco cable ensures the shelf's full current draw is delivered without excessive voltage drop. Installers should size breakers per the Cisco installation guide and verify polarity before energizing, since reversed DC feeds can trip plant protection and interrupt aggregation services.

Data Center ASR 9000 Satellite Deployment
In service provider and enterprise data centers deploying the ASR 9000v-V2 Satellite Shelf, the A9KV2-DC-CBL-E connects the shelf to -48V DC distribution, a topology chosen because DC power enables efficient power transmission, reduced energy consumption, and stable operation for networking equipment. The cable's ETSI connector mates with the shelf's DC power entry without adaptation, and its genuine Cisco construction preserves hardware warranty and TAC support entitlement. DC is often preferred over AC in these facilities because it removes rectifier-per-device conversions and simplifies battery-backup design. Plan one A9KV2-DC-CBL-E per power feed and stock spares, since Tech-America and 4networks listings show intermittent stock and backorder lead times as of 2026-10-19.
Recommended
Rack Integration and Factory Staging
During rack-level integration of ASR 9000 satellite systems, integrators stage the ASR 9000v-V2 Satellite Shelf with power, management, and fabric cabling before deployment. The A9KV2-DC-CBL-E is fitted at this stage to validate DC polarity, lug torque, and ETSI connector seating under controlled conditions. Using the exact Cisco MPN during staging eliminates the risk of discovering connector mismatch on site. Distributors such as Howard Computers identify the part explicitly as the power cable for the ASR 9000v-V2 Satellite Shelf (DC ETSI), and ITS directories classify it under power-cable categories. A common staging pitfall is ordering the older-generation A9K-AC-DC-CBL=; the Cisco Community confirms that cable serves first-generation ASR-9000V units, not V2 shelves.
Recommended
Network Spare-Parts Stocking Programs
Carrier spare-parts programs stock the A9KV2-DC-CBL-E=, the spares-orderable packaging of this identical cable, so field teams can replace damaged or lost DC feeds without waiting on project procurement. Distributor data shows meaningful price spread between listings - Zones at $186.99-$207.99 and 4networks at GBP 173.34 ex VAT as of 2026-10-19 - so bulk stocking agreements reduce per-unit cost. Because DC power cables are consumable-adjacent accessories frequently damaged during rack moves, maintaining at least one spare per populated ETSI shelf minimizes mean time to repair. Note that stock availability fluctuates; Tech-America reported the part out of stock, so programs should qualify at least two resellers or a Cisco spare-order channel.
Recommended
Mobile Backhaul and Remote Aggregation Sites
Remote aggregation and mobile backhaul sites frequently run on -48V DC plants with battery backup, making the DC ETSI variant of the ASR 9000v-V2 Satellite Shelf the default configuration there. The A9KV2-DC-CBL-E provides the mandated power feed between the DC plant and the shelf, and DC powering ensures the shelf rides through AC utility failures on plant batteries without per-device power supplies. Its ETSI-standard connector and genuine Cisco build support the environmental and reliability expectations of unattended sites. Field technicians should confirm plant voltage window and breaker coordination against the Cisco installation guide, and log cable MPN and torque values during installation for audit and warranty purposes.
Recommended
Cable Television and MSO Head-End DC Powering
Cable operator head-ends and hub sites commonly operate -48V DC plants, and MSOs deploying ASR 9000 aggregation with satellite shelves use the A9KV2-DC-CBL-E for the DC ETSI shelf variant. The cable delivers plant power to the shelf's ETSI power entry, supporting the high-availability uptime targets of video and broadband delivery networks. DC distribution in these facilities reduces conversion stages and provides a common battery-backed rail across routing, optical, and satellite equipment. Go Communications Systems notes this cable family is designed for data centers requiring high-speed connectivity around the ASR 9000 series, and genuine Cisco cabling keeps the deployment within Cisco support scope. Verify plant polarity and conductor sizing before commissioning each feed.

Key Differentiators
- Native compatibility with ASR 9000v-V2 ETSI shelf (vs A9K-AC-DC-CBL=)
- Lower street price than spares packaging (vs A9KV2-DC-CBL-E=)
- Genuine Cisco warranty and TAC entitlement preserved (vs Generic third-party DC cable)
Design Notes
Before energizing the A9KV2-DC-CBL-E feed, confirm DC plant polarity and breaker rating against the Cisco ASR 9000v-V2 satellite installation guide. ETSI practice uses positive-ground -48V DC; reversing polarity at the distribution panel can trip plant protection or damage shelf power circuitry. Verify the breaker coordinates with the shelf inrush and steady-state current, and land lugs on correctly sized ring terminals with a calibrated torque tool per the Cisco guide.
The most frequent ordering error is confusing generations: per a January 2025 Cisco Community thread, the A9K-AC-DC-CBL= serves first-generation ASR-9000V units, while the ASR 9000v-V2 Satellite Shelf (DC ETSI) requires the A9KV2-DC-CBL-E. Also note that the trailing '=' suffix is only Cisco spares packaging - A9KV2-DC-CBL-E= is the identical cable, often priced higher ($207.99 vs $186.99-$202.99 at Zones as of 2026-10-19). Buy the base MPN when both are available.
Route the DC cable away from fabric and management cabling in the rack to minimize coupled transients on signal lines, and maintain the bend radius recommended in the Cisco installation guide at the ETSI connector. Dress and strain-relieve the cable at the rack so lug weight does not load the shelf connector. Stock one spare cable per populated ETSI shelf; distributor stock is intermittent (Tech-America out of stock, 4networks backorder as of 2026-10-19), so lead time can extend field repairs.
